How can you control the congestion in tcp?
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
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.
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]
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 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 pieces of hardware can a network analyzer detect problems with?
Hubs, TCP/IP, Ports
What mechanism is used by tcp to provide flow control?
the station window size the congestion window memory buffers receipt acknowledgement
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.
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.
Why is header checksum required in TCP?
Its used to detect an error if the packet may be mis-routed. I'm not 100% sure.
What is the function Of RED?
the functions of the red cells is that it helps the DNA thing
What is elastic and inelastic internet traffic?
Elastic traffic: -adjust its throughput between end hosts in response to network condition. - Generally TCP-based application (HTTP,STMP,FTP) - Principle form of feedback: packet loss caused by network load/congestion, causing TCP to implements its congestion avoidance algorithm and reduce the rate at which packets are sent over the network -TCP traffic is considered to be "network friendly" Inelastic traffic: - does not adjust its throughput in response to network conditions - generally real-time multimedia (audio streaming, video,VoIP)
