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...
Network processing platform based on the multi-core CPU becomes more and more prevailing in nowadays. Buffer allocation/deallocation operations consume a large number of CPU cycles in packet I/O process. The problem becomes even worse in the scenario of packet forwarding, as buffer allocation/deallocation operations are more frequent than the host-based network applications. We thus propose a novel...
