An Analysis of 10-Gigabit Ethernet Protocol Stacks in Multicore Environments

Tags:
ethernet

Overview This paper analyzes the interactions between the protocol stack (TCP/IP or iWARP over 10-Gigabit Ethernet) and its multicore environment. Specially, for host-based protocols such as TCP/IP, one notices that a significant amount of processing is statically assigned to a single core, resulting in an imbalance of load on the different cores of the system and adversely impacting the performance of many applications. For host-offloaded protocols such as iWARP, on the other hand, the portions of the communication stack that are performed on the host, such as buffering of messages and memory copies, are closely tied with the associated process, and hence do not create such load imbalances.
