Buffer Requirements For TCP/IP Over ABR
Shiv Kalyanaraman, Raj Jain, Sonia Fahmy +1
We study the buffering requirements for zero cell loss for TCP over ABR. We show that the maximum buffers required at the switch is proportional to the maximum round trip time (RTT…
A Survey of Congestion Control Techniques and Data Link Protocols in Satellite Networks
Sonia Fahmy, Raj Jain, Fang Lu +1
Satellite communication systems are the means of realizing a global broadband integrated services digital network. Due to the statistical nature of the integrated services traffic,…
On Source Rules for ABR Service on ATM Networks with Satellite Links
Sonia Fahmy, Raj Jain, Shivkumar Kalyanaraman +2
During the design of ABR traffic management at the ATM Forum, we performed several analyses to ensure that the ABR service will operate efficiently over satellite links. In the cas…
Performance of TCP/IP Using ATM ABR and UBR Services over Satellite Networks
Shiv Kalyanaraman, Raj Jain, Rohit Goyal +2
We study the buffering requirements for zero cell loss for TCP/IP over satellite links using the available bit rate (ABR) and unspecified bit rate (UBR) services of asynchronous tr…
Performance of TCP over ABR on ATM backbone and with various VBR traffic patterns
Shiv Kalyanaraman, Raj Jain, Sonia Fahmy +3
We extend our earlier studies of buffer requirements of TCP over ABR in two directions. First, we study the performance of TCP over ABR in an ATM backbone. On the backbone, the TCP…
UBR+: Improving Performance of TCP over ATM-UBR service
Rohit Goyal, Raj Jain, Shiv Kalyanaraman +2
ATM-UBR switches respond to congestion by dropping cells when their buffers become full. TCP connections running over UBR experience low throughput and high unfairness. For 100% TC…
