Congestion control concerns controlling traffic entry into a telecommunications network, so as to avoid congestive collapse by attempting to avoid oversubscription of any of the processing or link capabilities of the intermediate nodes and networks and taking resource reducing steps, such as reducing the rate of sending packets.

Best method of transferring information between Gstreamer objects
In a gstreamer pipeline, I need a downstream element (a congestion control module) change the properties of an upstream element (an encoder) on the fly. What is the best mechanism to transfer this information?

Netty : back propogate pressure in channel handler pipeline to slow down sender
I am using netty to devlope application which will listen on specific port over TCP.
Once bytes received, I have a pipeline with business logic to run on received bytes.
This pipeline consist of multiple channel handlers like header decoder,…

Linux TCP congestion control algorithm in NS2
I am using NS2 and I have version 2.35 on my Ubuntu 16.04 with kernel 4.4.0. The default TCP congestion algorithm for my Ubuntu is CUBIC.
Which congestion control algorithm do they exactly use when I make Linux TCP agents in NS2?
At first, I thought…

Why congestion control is deployed at end hosts
Why is the congestion control process deployed at sender nodes?
I know one of the limitations that avoid deploying congestion control at routers is that routers need to maintain flow states, which increases the burden of routers. Put this aside, Is…

What can I do to decrease the impact of TCP's congestion control in ubuntu?
I am carrying out an experiment in which I turn on and off the network for random amounts of time. I expect packet exchange to begin as soon as I turn the network on again. However, I am seeing a sequence of consecutive on and off periods occurring…

Link saturation/capacity optimization algorithm
My question is related to telecommunications, but it's still pure programming challenge since I'm using a Soft-switch.
Goal:
create algorithm used by call routing engine to fully saturate
available link capacity with traffic sold at highest…

Retransmissions in Consecutive duplicated ACK in TCP
In the fast retransmission logic in TCP, TCP retransmit the packet when the sender gets the 3 duplicated ACKs. However, what if the sender gets 6 duplicated ACKS?
The following procedure is what I think,
1) sender sends lots of packets with big…

Congestion and traffic
I have seen somewhere while studying TCP , that if there is traffic in the networks, then it is not necessary that congestion is also there? What is the difference between Congestion and Traffic in computer networks?

How to implement pathfinding and congestion detection with neural network?
This is a conveyor system. Boxes enter the system at A and move towards C where they exit the system. The same goes for B->D.
Boxes on path A->C have higher priority than boxes B->D. Boxes can stop and wait in each square. If there is a box on A2…

Congestion control is network phenomenon , then why and how this is handled on transport layer.?
Congestion control is network phenomenon , then why and how this is handled on transport layer. Congestion occurs among the intermediary devices (router) in the network. But yesterday i was reading a paper (Host-to-Host Congestion Control for TCP,…

Determining the time to receive in object using TCP
The question I am trying to figure out is:
In this problem we consider the delay introduced by the TCP slow-start
phase. Consider a client and a Web server directly connected by one
link of rate R. Suppose the client wants to retrieve an…

Slow Start in ECN supported TCP
Assume a host joins with others to send packets to one host. All hosts connect to a switch that support ECN marking.
If the time it joins is when network congested and switch marks every packets incoming.
But this host is only begin at Slow-Start…

Congestion Control Algorithm at Receiver
Assume we talking about the situation of many senders sending packets to a receiver.
Often senders would be the one that control congestion by using sliding window that limits sending rate.
We have:
snd_cwnd = min(cwnd,rwnd)
Using explicit or…
