Deadlock situations in TCP over ATM
IFIP Workshop on Protocols for High Speed Networks IV, Vancouver August 1994
abstract | bibtex | full text: [pdf]
The implementation of protocols, such as TCP/IP, and their integration into the operating system environment is very decisive for protocol performance. Putting TCP on high-speed networks, e.g. ATM, with large maximum transmission units causes the TCP maximum segment size to be relatively large. What Nagle s consider small is not small anymore. We report on TCP/IP throughput performance measurements over Fore s ATM cards between two Sun IPX machines running SunOS 4.1.1 for various sizes of send and receive socket buffers. For some common combinations of socket buffer sizes we observe a dramatic performance drop to less than 3% of normal throughput. The drop is caused by a deadlock situation in the TCP connection which is resolved by the 200 msec timer generated TCP acknowledgment. The factors which in combination force the TCP connection into deadlocks are large MSS s, asymmetry of the socket buffer sizes, use of Nagle s algorithm, the delayed acknowledgment strategy, the sequence of actions on acknowledgment reception, and at last the socket layer optimization for efficient memory management. We explain what causes the deadlock situations, discuss some alternatives to avoid or prevent the situations and present measurement results from proposed changes in the implementation.
