Socket buffer (SKB) is the standard data structure for exchanging packets and their control information between NIC driver and protocol stack. The overhead of dynamic SKB management has been considered as the significant bottleneck in packet I/O. Some novel non-SKB mechanisms, such as DPDK, were thus proposed to solve the problem. However, these mechanisms usually cannot be widely adopted in the data...
The demands of programmability have become more and more exigent as novel network services appear, such as E-commerce, social softwares, and online videos. Commodity multi-core CPUs have been widely applied in network packet processing to get high programmability and reduce the time-to-market. However, there is a great gap between the packet processing performance of commodity multi-core and that...
