A new server I/O architecture for high speed networks

Guangdeng Liao, Xia Znu, Laxmi Bnuyan
2011 2011 IEEE 17th International Symposium on High Performance Computer Architecture  
The new architecture allows DMA engine to have very fast access to descriptors and keeps packets in CPU caches instead of NIC buffers, significantly simplifying NICs.  ...  They are inefficient for high-speed network processing with a bandwidth of 10Gbps and beyond. Long latency I/O interconnects on mainstream servers also substantially complicate the NIC designs.  ...  Acknowledge ments The research was supported by NSF grants CCF -0811834, CSR-0912850, and a grant fro m Intel Corporation.  ...
