From: Karthik Balaguru on 4 Mar 2010 21:10 Hi, In the case of error control, the positive/negative acks play a great role to help the sender in deciding on the retransmission. It seems that the sender has to maintain a timer for every frame in Data Link Layer. But, wouldn't maintaining a timer for every frame a very high overload in high speed connections ? Even if we go in for some counter based timers, every frame specific timer (counter based) should be monitored which in turn consumes some CPU resources. How is this scenario handled in x86 processor ? Any ideas ? Thx in advans, Karthik Balaguru
