TCP uses three mechanisms to trigger the transmission of data segments:
1. It sends a segment when it has collected MSS bytes from the sending process, where MSS is usually the largest segment size without IP fragmentation.
2. The sending process explicitly requests TCP to send data using the push operation.
3. A timer expires, causing TCP to send as many buffered bytes as possible in a segment.

Overview of SCTP (Stream Control Transmission Protocol)Peter R. Egli
Overview of SCTP (Stream Control Transmission Protocol), outlining the main features and capabilities of SCTP.
SCTP is a transport protocol that overcomes many of the shortcomings of TCP, namely head-of-line blocking and stream-oriented transmission.
SCTP supports multiple streams within a connection and preserves boundaries of application messages thus greatly simplifying communication.
Additionally, SCTP supports multi-homing which increases availability in applications with high reliability demands.
SCTP inherits much of the congestion, flow and error control mechanisms of TCP.
SCTP has its roots in telecom carrier networks for use in transitional voice over IP scenarios.
However, SCTP is generic so that it is applicable in many enterprise applications as well.
A distributed system is a collection of computational and storage devices connected through a communications network. In this type of system, data, software, and users are distributed.

NetWork Design Question2.) How does TCP prevent Congestion Dicuss.pdfoptokunal1
NetWork Design Question
2.) How does TCP prevent Congestion? Dicuss the information identifying congestion in the
network as well as the mechanism for reducing congestion?
Solution
Congestion is a problem that occurs on shared networks when multiple users contend for access
to the same resources (bandwidth, buffers, and queues).
Transmission Control Protocol (TCP) uses a network congestion-avoidance algorithm that
includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, with
other schemes such as slow-start to achieve congestion avoidance.
The TCP congestion-avoidance algorithm is the primary basis for congestion control in the
Internet.
Congestion typically occurs where multiple links feed into a single link, such as where internal
LANs are connected to WAN links. Congestion also occurs at routers in core networks where
nodes are subjected to more traffic than they are designed to handle.
TCP/IP networks such as the Internet are especially susceptible to congestion because of their
basic connection- less nature. There are no virtual circuits with guaranteed bandwidth. Packets
are injected by any host at any time, and those packets are variable in size, which make
predicting traffic patterns and providing guaranteed service impossible. While connectionless
networks have advantages, quality of service is not one of them.
Shared LANs such as Ethernet have their own congestion control mechanisms in the form of
access controls that prevent multiple nodes from transmitting at the same time.
Identifying:
Congestion is primarily reflected by a conventional user feeling-- slowness. This statement
reflects the change in the network effective flow, that is the time required to transmit an entire
data from one point to another. The effective flow doenot exist as such, it consists in reality of
three seperate indicators:
*Latency:the effective flow is inversely proportional to the latency.
*Jitter:it is latency variation over time, impacts by influencing the flow latency
*Loss Rate:the theoritical bandwidth is inversely proportional to the square root of the loss rate
These Congestion symtoms allow us to rely on objective indicators to characterize it.
Mechanism to reduce congestion:
The standard fare in TCP implementations today has four standard congestion control algorithms
that are now in common use. Their usefulness has passed the test of time.
The four algorithms, Slow Start, Congestion Avoidance, Fast Retransmit and Fast Recovery are
described below. (a) Slow Start
Slow Start, a requirement for TCP software implementations is a mechanism used by the sender
to control the transmission rate, otherwise known as sender-based flow control. This is
accomplished through the return rate of acknowledgements from the receiver. In other words, the
rate of acknowledgements returned by the receiver determine the rate at which the sender can
transmit data. When a TCP connection first begins, the Slow Start algorithm initializes a

A Packet Drop Guesser Module for Congestion Control Protocols for High speed ...ijcseit
Different high speed Transport layer protocols have been designed and proposed in the literature to
improve the performance of standard TCP on high BDP links. They are mainly different in their increase
and decrease formulas of their respective congestion control algorithm. Most of these high speed protocols
consider every packet drop in the network as an indication of congestion and they immediately reduce their
congestion window size. Such an approach will usually result in under utilization of available bandwidth in
case of noisy channel conditions. We take CUBIC as a test case and have compared its performance in
case of normal and noisy channel conditions. The throughput of CUBIC was drastically degraded from
50Mbps to 0.5Mbps when we introduced a random packet drops with 0.001 probability. When the
probability of the packet drops increases then the throughput gets decreases. Indeed, we need to
complement existing congestion control algorithms with some intelligent mechanisms that can differentiate
whether a certain packet drop is because of congestion or channel error thus avoid unnecessary window
reduction. In order to distinguish between packets drops, we have developed a k-NN based module to guess
whether the packet drops are due to the congestion or any other reasons. After integrating this module with
CUBIC algorithm, we have observed significant performance improvement.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. Triggering Transmission
Triggering Transmission
How does TCP decide to transmit a segment?
– TCP supports a byte stream abstraction
– Application programs write bytes into streams
– It is up to TCP to decide that it has enough bytes to send a segment.
TCP has three mechanism to trigger the transmission of a segment
i. TCP maintains a variable MSS and sends a segment as soon as it has
collected MSS bytes from the sending process
• MSS is usually set to the size of the largest segment TCP can send without causing
local IP to fragment.
• MSS: MTU of directly connected network – (TCP header + and IP header)
ii. Sending process has explicitly asked TCP to send it
• TCP supports push operation
iii. When a timer fires
• Resulting segment contains as many bytes as are currently buffered for
transmission
3. Triggering Transmission
Silly Window Syndrome
In TCP “full” containers (data segments) going in one direction and
empty containers (ACKs) going in the reverse direction, then MSS-
sized segments correspond to large containers and 1-byte segments
correspond to very small containers.
If the sender aggressively fills an empty container as soon as it
arrives, then any small container introduced into the system remains
in the system indefinitely.
That is, it is immediately filled and emptied at each end.
4. Triggering Transmission
Nagle’s Algorithm,
If there is data to send but the window is open less than MSS, then we may
want to wait some amount of time before sending the available data.
If we wait too long, then we hurt interactive applications like Telnet.
If we don’t wait long enough, then we risk sending a bunch of tiny packets and
falling into the silly window syndrome.
o The solution is to introduce a timer and to transmit when the timer expires.
Nagle introduced an elegant self-clocking solution
Key Idea
o As long as TCP has any data in flight, the sender will eventually receive an ACK
o This ACK can be treated like a timer firing, triggering the transmission of more data
5. Triggering Transmission
When the application produces data to send
if both the available data and the window ≥ MSS
send a full segment
else
if there is unACKed data in flight
buffer the new data until an ACK arrives
else
send all the new data now
