This document provides an introduction to HTTP/2, including:
- HTTP/1.x has drawbacks like occupying one TCP connection per request and slow start-up times.
- HTTP/2 aims to address these by being binary based, multiplexed, compressed and allowing server push.

The status is categorized as official, unofficial, or multiple use to indicate if the port is registered with IANA for a specific application, not registered, or can be used by multiple applications.
TCP provides reliable data transfer over unreliable packet networks by using acknowledgments, retransmissions, and adaptive congestion control. It works with IP to transfer data through routers that may drop packets. While TCP ensures reliable delivery, it must control its transmission rate to avoid overwhelming network capacity and causing congestion collapse. This is achieved through additive-increase, multiplicative-decrease of the congestion window and techniques like active queue management.
The document discusses multimedia communication protocols including SDP, RTSP, and SIP. SDP is used to describe multimedia sessions to enable clients to join.

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.
This document discusses different types of ports including TCP Port Service Multiplexer which allows contacting TCP services on a single well-known port number, the Echo Protocol for testing round-trip network times, the Discard Protocol for testing and measurement, file transfer for transmitting files over networks, and the Time Protocol for time synchronization over the Internet.

Analysis of Link State Resource Reservation Protocol for Congestion Managemen...ijgca
With the wide spread of WiFi hotspots, concentrated traffic workload on Smart Web (SW) can slow down
the network performance. This paper presents a congestion management strategy considering real time
activities in today’s smart web. With the SW context, cooperative packet recovery using resource
reservation procedure for TCP flows was adapted for mitigating packet losses. This is to maintain data
consistency between various access points of smart web hotspot. Using a real world scenario, it was
confirmed that generic TCP cannot handle traffic congestion in a SW hotspot network. With TCP in
scalable workload environments, continuous packet drops at the event of congestion remains obvious. This
is unacceptable for mission critical domains. An enhanced Link State Resource Reservation Protocol (LSRSVP)
which serves as dynamic feedback mechanism in smart web hotspots is presented. The contextual
behaviour was contrasted with the generic TCP model. For the LS-RSVP, a simulation experiment for TCP
connection between servers at the remote core layer and the access layer was carried out while using
selected benchmark metrics. From the results, under realistic workloads, a steady-state throughput
response was achieved by TCP LS-RSVP to about 3650Bits/secs compared with generic TCP plots in a
previous study. Considering network service availability, this was found to be dependent on fault-tolerance
of the hotspot network. From study, a high peak threshold of 0.009 (i.e. 90%) was observed. This shows
fairly acceptable service availability behaviour compared with the existing TCP schemes. For packet drop
effects, an analysis on the network behaviour with respect to the LS-RSVP yielded a drop response of about
0.000106 bits/sec which is much lower compared with the case with generic TCP with over 0.38 bits/sec.
The latency profile of average FTP download response was found to be 0.030secs, but with that of FTP
upload response, this yielded about 0.028 sec. The results from the study demonstrate efficiency and
optimality for realistic loads in Smart web contexts.
The document summarizes key concepts about the TCP/IP transport and application layers:
1) The transport layer provides five basic services: segmenting data, establishing end-to-end operations, transporting segments, ensuring data reliability, and providing flow control.
2) TCP uses a three-way handshake for connection establishment and positive acknowledgment with sequence numbers to ensure reliability.
3) Common transport layer protocols are TCP and UDP, with TCP being connection-oriented and reliable while UDP is connectionless.
4) The application layer defines protocols for functions like DNS, FTP, HTTP, SMTP, and Telnet.
Overview of UDP protocol.
UDP (User Datagram Protocol) is a simple extension of the Internet Protocol services. It basically provides simple packet transport service without any quality of service functions.
Unlike TCP, UDP is connection-less and packet-based. Application PDUs (application packets) sent over a UDP socket are delivered to the receiving host application as is without fragmentation.
UDP is mostly used by applications with simple request-response communication patterns like DNS, DHCP, RADIUS, RIP or RPC.
Since UDP does provide any error recovery such as retransmission of lost packets, the application protocols have to take care of these situations.
This document summarizes the /etc/services file, which defines network services and their associated port numbers. It notes that the file contains services defined by IANA in the Assigned Numbers registry, including well-known ports from 0-1023, registered ports from 1024-49151, and dynamic/private ports from 49152-65535. Each entry lists the service name, port number, transport protocol, and optional comments or aliases.

The document describes the TCP/IP model and its layers:
1. The application layer contains common protocols like FTP, SMTP, HTTP, and DNS.
2. The transport layer contains TCP and UDP which manage end-to-end message transmission and error handling.
3. The network layer is IP which handles routing and congestion of data packets.
4. The lower layers include the data link layer which manages reliable data delivery to physical networks, and the physical layer which defines the physical media.
MainlineNet Holdings owns Extreme TCP, a new technology that improves upon the standard TCP congestion avoidance algorithm used on the internet. Extreme TCP uses complex router and network models to transmit data at higher speeds while avoiding congestion events that slow transmission. Testing showed transmission speed improvements of 400-1000% for some connections and up to 1400% for longer connections. While Extreme TCP can be applied as a software patch, its benefits are only seen on the device that has it installed, not requiring widespread adoption. It has the potential to significantly increase transmission speeds for most internet communications that use TCP.

The Application layer consists of protocols that focus on process-to-process communication across an IP network and provides a firm communication interface and end-user services. These services are sub protocols with specific goals.
ARP (Address Resolution Protocol) is responsible for resolving internet addresses into link layer addresses. It is also used for mapping a network address to a physical address.
TCP (Transmission Control Protocol) is connection-oriented, reliable communications service responsible for the establishment of a TCP connection, the sequencing and acknowledgement of packets sent, and the recovery of packets lost during transmission.
UDP (User Datagram Protocol) is used when the amount of data to be transferred is small, or when the applications or upper layer protocols provide reliable delivery.
FTP (File Transfer Protocol) allows files to be transferred between computers
HTTP (Hypertext Transfer Protocol) is used to transfer web pages to end-users.
Telnet is a bi-directional text communication via a terminal application; it’s used for logging on remotely to network hosts.
How does TCP ensure reliable delivery?
The TCP provides reliable communications services by providing sequencing services to the packets sent as well as an acknowledgment service. When the correct response is not received, TCP process the packet again to assure the requested transfer happens.

The document discusses several networking protocols including TCP/IP, Netware, IEEE 802 standards, IPX, UDP, IP, ARP, SMTP, POP, IMAP and more. It provides information on what each protocol is used for, such as IP being used for addressing, routing packet selection, and fragmentation. It also compares the OSI model, DoD model and TCP/IP protocol suite, noting similarities and differences between the layers and protocols of each.
TCP/IP was developed by DARPA in 1969 and is now the standard protocol for internet communication. It operates on a layered model with an application layer that includes protocols like HTTP, FTP, and SMTP. Below this is the transport layer, which includes TCP (connection-oriented) and UDP (connectionless). The internet layer includes IP and protocols for address resolution like ARP. The network access layer deals with data link protocols like Ethernet.
This document provides an overview of the TCP/IP and HTTP protocols. It describes TCP/IP as a standardized protocol used widely on the Internet that maps to a four-layer model consisting of network interface, internet, transport, and application layers. The layers contain independent protocols like IP, TCP, UDP, HTTP, and FTP. HTTP is specifically defined as a stateless protocol where a web client makes a request over TCP, the server responds with content, and the connection is typically closed.
This document provides an overview of TCP/IP and DNS. It describes the architecture of TCP/IP including the physical, data link, internet, transport and application layers. It explains how data moves between layers and across networks. Key TCP/IP concepts covered include IP, TCP, UDP, ARP and ICMP. The document also defines DNS and describes domain name space and the different types of DNS servers.
In this presentation, we will discuss in details about the TCP/ IP framework, the backbone of every ebusiness.

The document discusses Internet Protocol (IP) which specifies the format of data packets and the addressing scheme used on networks. IP allows for addressing and dropping packets in the network system like a postal system, but does not directly connect the source and recipient. Most networks combine IP with Transmission Control Protocol (TCP) to establish a connection between hosts to send messages back and forth. Commonly used internet protocols include TCP/IP, FTP, and HTTP. IP addresses provide a unique global address for network interfaces and encode network and host numbers. While IPV4 is currently used, IPV6 is designed to replace it and provide more addresses and functionality for future internet growth.
Network protocols are sets of rules that allow computers to communicate over a network. TCP/IP is a widely used set of protocols that power the internet. TCP/IP was developed in the 1970s-80s and includes protocols like TCP, IP, HTTP, and FTP. Network protocols define data formats, error handling, routing, and other aspects of network communication to ensure reliable data transmission between devices. Common protocols serve functions like file transfer, email delivery, and network management. Protocols provide benefits like increased connectivity and speed for data transmission.
This document discusses network protocols. It begins with an introduction and history of protocols and defines them as sets of rules that govern communications between devices on a network. Examples of common protocols are then outlined, including TCP/IP, HTTP, FTP, SMTP, UDP, and ICMP. The roles and functions of protocols are explained. Benefits include increased connectivity and transmission speed. The conclusion states that protocols have transformed human communication and networks will continue to evolve.
"Internet Protocol Suite" prepared by Szymon M. from Polandirenazd
The document summarizes the Internet Protocol Suite (TCP/IP), which is the set of communication protocols used for the Internet and similar networks. It consists of four layers - link, internet, transport, and application layers. Some important protocols included in each layer are IP, TCP, UDP, and higher-level protocols like HTTP, FTP, and SMTP. The TCP/IP model uses encapsulation, adding headers at each layer to abstract the protocols and allow communication across networks.
The application layer is the highest level of abstraction in networking models like TCP/IP and OSI. It defines protocols for process-to-process communication across networks. In TCP/IP, common application layer protocols are FTP for file transfer, SMTP for email, and HTTP for the web. The application layer depends on lower layers like transport for establishing connections between hosts.
This document provides an overview of the TCP/IP model and its layers:
1. It describes the 7 layers of the TCP/IP model from the physical layer up to the application layer.
2. It explains some of the key protocols used at each layer, including IP, TCP, UDP, FTP, and HTTP.
3. It provides brief histories of TCP/IP and how it emerged from ARPANET in the 1960s to become the fundamental protocol of the Internet.
A protocol is a set of rules for exchanging data between two or more computers. Common internet protocols include SMTP for email, FTP for file transfers. The TCP/IP model uses protocols like IP and TCP. IP is an unreliable connectionless protocol that does not guarantee delivery. TCP provides reliable data delivery through a connection-oriented approach requiring a connection be established before transmitting data. Common TCP/IP application layer protocols are Telnet, FTP, SMTP, and SNMP for network management. Devices on a TCP/IP network are assigned unique 32-bit IP addresses divided into four octets separated by periods, which can be static or dynamically assigned by DHCP.
FTP (File Transfer Protocol) allows users to upload and download files between a client and server. It uses TCP ports 20 and 21 and supports both ASCII and binary transfer modes. FTP connections can be initiated directly or through a proxy server using PASV mode, and FTP servers like wu-ftpd provide features like access control, logging, and compression.
