Internet Protocol (IP) is used to carry data from source to destination hosts across the Internet by providing addressing, fragmentation and reassembly, packet timeouts, and prioritization of traffic. IP uses 32-bit addresses to identify sending and receiving hosts and allows packets to be split into smaller fragments if needed to travel across networks. Routers use the IP Time to Live field to discard packets that have been traveling too long to prevent flooding of networks.

IP uses 32-bit addresses to identify sending and receiving hosts and allows packets to be split into smaller fragments if needed to travel across networks. Routers use the IP Time to Live field to discard packets that have been traveling too long to prevent flooding of networks.
The network layer is responsible for routing packets from the source to destination. The routing algorithm is the piece of software that decides where a packet goes next (e.g., which output line, or which node on a broadcast channel).For connectionless networks, the routing decision is made for each datagram. For connection-oriented networks, the decision is made once, at circuit setup time.
Routing Issues
The routing algorithm must deal with the following issues:
Correctness and simplicity: networks are never taken down; individual parts (e.g., links, routers) may fail, but the whole network should not.
Stability: if a link or router fails, how much time elapses before the remaining routers recognize the topology change? (Some never do..)
Fairness and optimality: an inherently intractable problem. Definition of optimality usually doesn't consider fairness. Do we want to maximize channel usage? Minimize average delay?
When we look at routing in detail, we'll consider both adaptive--those that take current traffic and topology into consideration--and nonadaptive algorithms.
SMTP is a protocol used to transfer email between servers. It uses a push protocol to send email from the sender to the receiver's email server, while POP3 or IMAP are used by the receiver to retrieve emails. SMTP uses TCP connections to transfer emails and operates using a client-server model, with SMTP servers listening for connections from SMTP clients to deliver emails. SMTP can use either an end-to-end or store-and-forward delivery method to route emails between organizations or within an organization.

AMQP (Advanced Message Queuing Protocol) is an open standard protocol for message queuing that aims to provide interoperability between platforms and vendors. It defines a wire-level protocol for message passing that can be implemented by different technologies, unlike proprietary middleware which is locked to specific platforms. AMQP includes concepts like exchanges, bindings, queues, and different exchange types (fanout, direct, topic) to route messages from publishers to subscribers in a decoupled manner. Several open source and commercial brokers like RabbitMQ and Qpid implement the AMQP standard.
Telnet is a protocol that allows administrators to remotely access and manage devices, but it transmits usernames and passwords in clear text, posing a security risk. SSH is a more secure replacement for Telnet, as it encrypts all transmitted data using public key cryptography. Both protocols require a client and server, with Telnet using port 23 and SSH typically using port 22.
HTTP is a protocol for transmitting hypermedia documents across the internet. It uses a client-server model where browsers make HTTP requests to web servers, which respond with HTTP responses. Key aspects of HTTP include using TCP/IP for communication, being stateless, supporting a variety of data types, and incorporating features of both FTP and SMTP protocols.
Web services allow for integration both within and between organizations through standardized XML messaging over the internet. The core technologies that enable web services are SOAP, which defines a standard messaging protocol, WSDL, which describes service interfaces, and UDDI, which allows services to be published and discovered. SOAP uses XML for flexible, self-describing messages and takes advantage of XML features like namespaces and schemas. It defines an envelope, header and body structure. Common uses of web services include processing purchase orders, answering inquiries, and processing shipment requests across organizational boundaries without tight coupling between partners.
The document discusses the World Wide Web (WWW) and Hypertext Transfer Protocol (HTTP). It describes the basic architecture of the WWW including clients, servers, web pages, and URLs. It explains that web pages can be static, dynamic, or active. The document then discusses HTTP in more detail, including how HTTP requests and responses are structured, how persistent connections work in HTTP 1.1, and how caching can improve performance.
This document describes the sliding window protocol. It discusses key concepts like both the sender and receiver maintaining buffers to hold packets, acknowledgements being sent for every received packet, and the sender being able to send a window of packets before receiving an acknowledgement. It then explains the sender side process of numbering packets and maintaining a sending window. The receiver side maintains a window size of 1 and acknowledges by sending the next expected sequence number. A one bit sliding window protocol acts like stop and wait. Merits include multiple packets being sent without waiting for acknowledgements while demerits include potential bandwidth waste in some situations.
Ns-3 is a new discrete event network simulator written completely in C++. It is not an extension of the older ns-2 simulator and does not support ns-2 APIs, although some models have been ported over. Ns-3 uses a library and build system approach and simulation programs are executable C++ programs. It simulates networking by modeling events like packet transmission and handling a list of scheduled events. Users can create network topologies, data traffic models, and analyze results from trace files and custom tracing of packets and nodes.
The document discusses the Simple Network Management Protocol (SNMP). SNMP is an application layer protocol used to manage network devices. It allows network administrators to monitor network-attached devices, retrieve performance metrics and configure device parameters. The key components of SNMP include SNMP managers, agents and MIBs (Management Information Bases). SNMP agents run on network devices and collect data from the device. SNMP managers communicate with agents to read/write data in MIBs to configure and monitor devices. The document describes the evolution of SNMP from versions 1 to 3, with newer versions focusing on improved security and management functionality.

OpenFlow is a standard protocol that allows separation of the control plane from the data plane in network devices like switches. It defines communications between controllers and switches. Controllers install flow entries in switches' flow tables which determine how traffic is forwarded. This allows centralized control over distributed switches using protocols like OpenFlow to program their forwarding behavior.
Overview of RARP, BOOTP, DHCP and PXE protocols for dynamic IP address assignment.
Dynamic IP address assignment to a host (or interface) is a common problem in TCP/IP based networks.
Manual and static assignment of IP addresses does not scale well and becomes a labor intensive task with a growing number of hosts.
An early approach for dynamic IP address assignment was RARP (Reverse ARP) which ran directly on the Ethernet protocol layer.
The many problems of RARP such as the inability to be routed between subnets were solved with BOOTP (Bootstrap Protocol).
BOOTP, however, ended to have its own set of limitations like lack of a lease time for IP addresses.
DHCP (Dynamic Host Configuration Protocol) was therefore defined as an extension to BOOTP.
DHCP is backward compatible with BOOTP thus allowing some degree of interoperability between the 2 protocols.
The state-of-the-art protocol for dynamic IP address assignment is, however, is DHCP.
DHCPv6 is an adaption of DHCP for IPv6 based networks.
TCP is a connection-oriented, reliable transport protocol that provides stream delivery, connection-oriented, and reliable services. It uses sequence numbers, acknowledgment numbers, and other features like flow control, error control, and congestion control to reliably deliver data between two endpoints. A TCP connection involves three phases - connection establishment using a three-way handshake, reliable data transfer with acknowledgments, and connection termination with another three-way handshake or four-way handshake with half-close option. TCP works well for both low and high-speed networks.
SNMP (Simple Network Management Protocol) allows network devices to be monitored and managed. It defines an agent-manager architecture where agents run on devices and respond to requests from managers to retrieve or store management information. SNMP uses a management information base (MIB) and structure of management information (SMI) to define managed objects and their properties. Key SNMP components include versions 1 and 2, protocol data units (PDUs) like get, set, and trap requests, and error codes. SNMP traps allow agents to asynchronously notify managers of events.
This document provides an overview of the Transmission Control Protocol (TCP). It discusses TCP services like reliable data delivery and connection-oriented communication. The document explains TCP features such as flow control, error control, and congestion control. It describes TCP segments, the three-way handshake for connection establishment, and the TCP state transition diagram. Examples are provided to illustrate TCP windows, acknowledgments, retransmissions, and timers.
This document describes a project analyzing source location privacy in wireless sensor networks through probabilistic model checking. It will model an algorithm for protecting source location privacy using the PRISM model checker. The model will be analyzed based on the probability of source location capture, expected number of messages, and expected time to source location capture. Future work may include implementing additional algorithms, expanding the network size, new network structures, and using high performance computing for larger models.
The main aim of this project is to avoid the accident and death in the gas leakage explosion in house, hotels and industries. Domestically we use natural gas and it is very useful for burning purpose. If this gas is leaked in our kitchens, hotels or factories and not sensed in time, it may lead to fatal disaster, and may cause human and material loss. For this purpose we have developed “GAS LEAKAGE DETECTION SYSTEM”.

Final Project
Final Project Details:
Description: Given a specific scenario, create an appropriate IP addressing scheme, document a given network by creating a logical network diagram and create the appropriate access lists for use on the routers. Deliverables:
· Demonstrate the theory and practice of Cisco networking, routing, and switching strategies as outlined in the Cisco CCENT Certification exam
Prior to implementing any design we need to first write-up our proposed network design on paper. With that in mind, we begin by performing a network discovery. Once we have identified all the network devices and the needs of the organization, we can document the TCP/IP information that is needed for our design. In this exercise you will determine the subnet information for each department and assign IP addresses for the network devices.
You have been assigned as a networking tech for a new client, AAA Fabricating. The network is configured with a Class C network and the current allocation of IP addresses has been depleted. You have been tasked to reconfigure the network with a Class B address and assign a subnet to each of the 10 departments and the three routers.
Your network audit consists of the following information:
AAA Fabrication consists of 10 departments spread across three buildings.
Each building is connected using three Cisco 2800 Series routers. The three routers are located in the MIS wiring closet in Building 2.
Each department has its own Cisco 2950 switch.
There are at least two workstations in each department.
The company plans to use a class B address range starting at 172.16.0.0.
Each department must be assigned a subnet. Subnets should be designed to allow for the maximum number of hosts on each department subnet using classful subnetting.
The company also wants the three routers to communicate on the minimum quantity of IP addresses using three subnets.

Varibale frequency response lecturer 2 - audio+Jawad Khan
This document discusses Bode plots, which are used to analyze the frequency response of variable-frequency networks. Bode plots consist of two graphs: a magnitude plot using a logarithmic scale on the horizontal axis to show gain or attenuation over frequency, and a phase plot to show phase shift over frequency. Zeros cause positive gain slopes on the magnitude plot, while poles cause negative slopes. Phase is determined from the tangent inverse of the transfer function. Bode plots provide an efficient way to understand a network's behavior at different frequencies.

There are four admittance parameters - Y11 is the short circuit input admittance, Y12 and Y21 are the short circuit transfer admittances, and Y22 is the short circuit output admittance. The document provides an example of calculating the admittance parameters for a given two-port network.
4. ideal transformer and load conversionJawad Khan
1) The ideal transformer ensures that no magnetic flux escapes and that it is lossless.
2) The ideal transformer equations relate the voltages and currents on the primary and secondary sides based on the turns ratio.
3) Impedances on one side of the transformer are reflected to the other side, following Ohm's law. The reflected impedance is proportional to the square of the turns ratio.
Magnetic coupled circuits involve circuits where the magnetic fields of coils or inductors are coupled or linked together. This causes the currents in each circuit to influence each other. Analysis of such circuits requires considering the effect of current in one coil on the magnetic flux and induced emf in the other coil.
1. The document describes writing mesh equations for circuits containing coupled inductors. It defines variables, writes loop equations in terms of inductor voltages, and derives equations relating the voltages in coupled inductors.
2. The equations for the coupled inductors are substituted into the loop equations and terms are rearranged to obtain the mesh equations solely in terms of inductor currents and voltages.
3. Additional examples are shown to determine the impedance seen by a source in a circuit containing coupled inductors by using similar steps: defining variables, writing loop equations, deriving coupled inductor equations, and substituting/rearranging terms.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Ground to ns3 - Basic wireless topology implementation
1. Ground to ns3
and
Implementing wireless topology
(Power Adaption) in ns3 plus
visualization in Network Animator
JAWAD ALI
UNIVERSITY OF ENGINEERING AND TECHNOLOGY PESHAWAR
2. Topics Covered
Introduction to ns3 and its comparison with ns2
Finding required modules for coding
Finding sample code
Understanding the code
Checking ns3 core-module.h
Adding animation interface to the code
Compiling and running simulation using NetAnim
Understanding the results from trace file
3. Introduction to ns3 and its comparison
with ns2
Ns3 is just like traditional network simulators and optimization softwares besides its ready to
modify codes and open source licensing
The drawback of ns3 as well as ns2 is that we can’t see the Graphical User Interface (GUI) while
building a project. All we can do is comment the c++ and otcl codes for its understanding. The
topology is defined in c++ in ns3
Ns2 uses traditional otcl and c++ language for its coding on the other hand ns3 uses object
oriented c++, gcc and python. Ns2 always needs otcl for its scripting and c++ for its core
In ns3, everything is c++. You should find it easy if you are good at OOP and c++
Ns2 only supports nam while ns3 supports both nam and PyViz for visualization
Overhead of connecting otcl with c++ in ns2 is removed in ns3, increasing simulation speed
Packet consists of a single portion in ns3 with metadata attached. Payload portion on the ns2
packet is this removed by defining packet as a single object.
4. Finding required modules for coding
Networking follows standards and these standards are kept in certain header files called modules
in ns3
For example, if want to initialize a node. You must initialize it as an object of the class called
nodecontainer that is defined in the network-module.h of ns3.
The same network module is responsible for addressing such as ipv4 addressing scheme.
The internet-module.h knows upd and tcp protocol schemes and one should use it in any
TCP/UDP based communication network.
Assigning applications to a node is done by referring to applicationcontainer, defined in
applications-module.h
Visualization needs network animator module and node topology formation needs a topology
module (e.g. point-to-point.h)
All of the above modules combined by core-module.h library that is responsible for the core work.
5. Finding sample code
For a pro in ns3, it is easy to figure out which module he/she is going to need if the scenario is
drawn on a rough page.
For example: Communication of a node with another node will require a topology defining
module, node formatter module, payload calculation module, application, visualization module
and core module.
For novice, it should be even a big deal to find a library. Though a library has to be known for its
classes and functions which is even a higher difficulty.
Therefore, it is a good programming practice to use already implemented codes and modify
according to our needs
Ns2 has a lot of online libraries as compared to ns3 but you need to understand otcl before any
modification in those ns2 based codes
Ns3 has a variety of user manuals and implemented codes given in ~/source/ns-3-dev/examples/
that are ready to use and to modify. One can easily find the desired sample code by roaming
through those examples
6. Understanding the code
After finding the closest sample code in the library, one needs to understand it.
Online help and documentation of each example is available so we should be
using that.
It is a good practice that one should first know about the scenario implemented in
the example code before roaming through the defined classes and objects called
by the developer of the code
7. Checking the ns3 core-module.h
Create a simple text file naming test1 in scratch directory of ns-3-dev with suffix .cc and
write the following code in it
#include <core-module.h>
using namespace std;
Int main (arg, arg )
{
cout<<“testing ns3 in terminal”;
Return 0;
}
Open terminal and type: cd source/ns-3-dev followed by ./waf –run test1
If you get the statement after you have written in console out. This most likely mean that
your core-module is working fine.
8. Adding Animation Interface to the code
#include "ns3/netanim-module.h“ header has to be included for enabling animation
generation in the compiling code
Also, before
Simulation::Run();
include
AnimationInterface anim ("animation.xml"); //or any other distinct fie name
9. Power Adaption (Compiling and running simulation
using NetAnim)
The simulation consists of 4 Nodes. Of which, 2 nodes are mobile access points
while 2 are Stations (STA#)
• The APs generates UDP traffic with a CBR of 54 Mbps to the STAs.
• The APs use any power and rate control mechanism, and the STAs use only * Minstrel
rate control.
• The STAs can be configured to be at any distance from the APs.
# A station in networking is a device that follows 802.11 protocol
10. Code to run in the terminal
./waf --run "power-adaptation-interference --manager=ns3::AparfWifiManager --
outputFileName=aparf”
Changing STAs position
./waf --run "power-adaptation-interference --manager=ns3::AparfWifiManager --
outputFileName=aparf --STA1_x=5 --STA2_x=205“
To enable the log of rate and power changes
export NS_LOG=PowerAdaptationInterference=level_info
11. Animation Interface in NetAnim
Type ./NetAnim after exploring netanim directory in the terminal
Open the directory from where you have run the ./waf commands
Locate animation stored as .xml file
Open and run
Animation Interface consists of 3 tabs
Animator
