Re: [AVT] Congestion is unidirectional or bidirectional ???

["Saverio Mascolo" <mascolo at poliba.it>]

i would say it is unnidirectional for the flow that goes from A to B, but this flow could be affected by congestion on the reverse path in case the flow A-->B is ack clocked such as in the case of TCP

Subject: [AVT] Congestion is unidirectional or bidirectional ???

Dear all,

 

I have to ask you because I couldn't find the answer on the web to my question...sorry again.

 

Suppose I transmit a media flow between A and B, and these points are connected through Internet2 or a similar high-speed network.

 

Suppose that in a given moment, there is a congestion in the path from A to B (let's say caused by a given router) that makes that no packets reach B.

 

At this same moment........is there a congestion from B to A too ???

 

Congestion states are a unidirectional or a bidirectional problem ???

 

One person from Internet2 tells me that he supposes and has experienced that congestion is mostly unidirectional, but he has not a good academic cite to confirm this.

 

Thanks a lot,

 

Alejandro
