ABSTRACT
Current high speed networks cannot be fully utilized by today's high end systems. The processing requirements of applications and advanced services or security processing aggravate this situation. To overcome these shortcomings intelligent network cards with network protocol offload engines, for example based on a network processor, are necessary. To reduce development time, we reuse existing software protocol stack implementations for partitioning and implementing on the network card. Since manual partitioning is very expensive and fault-prone, we use a modified automatic debugging tool for the analysis. We outline the results of Linux TCP network stack analysis and partitioning when using an automatic debugger.

TCP-friendly Congestion Control for HighSpeed Network
SAINT '07: Proceedings of the 2007 International Symposium on Applications and the InternetThe currently used TCP congestion control, TCP Reno, has two weaknesses. To solve this TCP Reno drawback, HighSpeed TCP and Scalable TCP were proposed. However, the fairness between these proposed TCP and TCP Reno is not considered, when both ...
