How does TCP detect congestion?
It don't control congestion that is up to the routers and gateways as they are the ones that look at the traffic and figure out the best way to send something over the internet.
What is TCP-friendly?
TCP-Friendly Rate Control (TFRC) is a congestion control mechanism designed for unicast flows operating in an Internet environment and competing with TCP traffic. The goal is to compete fairly with TCP traffic on medium timescales, but to be much less variable than TCP on short timescales.[wiki]
How does TCP try to avoid network meltdown?
No, TCP is responsible for reliable transport delivery. It doesn't know about network congestion (other than flow control caused by ICMP messages).
What mechanism is used by tcp to provide flow control?
the station window size the congestion window memory buffers receipt acknowledgement
Why is that the tcp's rfc has more pages and is more complex than udp's rfc?
Because TCP does far more things than UDP. UDP does not do flow control or congestion control or guarantee in-order and reliable packet delivery. TCP does all those things therefore it needs more functionality.
What are the 3 major components of the TCP congestion-control algorithm and give a brief explanation of each?
The three major components of the TCP congestion-control algorithm are slow start, congestion avoidance, and fast recovery. Slow Start: This phase begins with a small congestion window (cwnd) size, typically starting at one segment, and increases exponentially with each acknowledgment received, allowing the sender to probe the network capacity. Congestion Avoidance: Once the congestion window reaches a certain threshold (ssthresh), TCP transitions to this phase, where it increases the window size linearly to avoid overwhelming the network, thereby reducing the likelihood of congestion. Fast Recovery: This mechanism kicks in after packet loss is detected (usually through duplicate acknowledgments), allowing TCP to quickly reduce the congestion window and retransmit lost packets without returning to the slow start phase, thus improving overall efficiency.
Why is TCP fair?
TCP uses congestion control mechanisms such as slow start, congestion avoidance, and fast retransmit to ensure fairness among competing connections by sharing available network bandwidth proportionally. Through dynamically adjusting its sending rate based on network conditions, TCP strives to ensure that all connections have an equal chance of utilizing the network resources.
How does sctp differ from tcp?
SCTP is a protocol that has the ability to deliver functionality that is similar to TCP. Like TCP, an SCTP session can be configured to offer ordered, guaranteed, delivery with congestion control and a notion of a session. It differs in that it offers other features and has an implementation that is not directly compatible with TCP; both peers' network stacks and applications will also need to support SCTP.
How does TCP handel the flow control problem explain it with the help of a diagram showing the status window at the different stages?
Tcp is a transport layer protocol which provides end to end delivery in sequence of byte stream. It is a reliable connection oriented protocol. To provide the reliable and correct data tcp performs various function in which one is "Flow control". In flow control function tcp handle timeout and retransmission of missed/duplicate packets. Time out and retransmission is a function performed to handle the congestion.
What is a congestion control mechanism?
Congestion control mechanisms are tools that control how backed up a substance may get. Traffic congestion control mechanisms can be stop lights, for example.
Which layer is done by congestion control?
at the network layer, congestion control mechanism takes place
What is tcp server processes?
The process of a TCP server is to receive TCP connections and handling the data correctly. The letters TCP in TCP server stands for transmission control protocol.
