Component-based Network Protocol Architecture for Multi-core

The architecture and implementation of network protocol stack is very important for network communication. And now CMP(Chip Multi-processor) architecture is the trend of CPU because of its excellent parallelism and high efficiency. So this paper proposes a Component-based Network Protocol Architecture(CNPAM) based on Intel Multi-core. In this architecture, two important modules are brought in: distribution module and migration module. Distribution module takes charge of distributing close function components to the same core group in which the two cores share the L2 cache. And migration module guarantees the load balance of all cores. The performance of CNPAM gets a significant improvement.
