.... are necessary at the sender host in TCP data transfer [14] One is from the file system to the application buffer, and the other is from the application buffer to the socket buffer, as shown in Figure 1 (a) The problem is that memory access is the largest obstacle in improving TCP data transfer [15], so reducing the number of memory copy operations in TCP data transfer is a key to improving the server s protocol processing speed. Reducing the number of memory accesses in TCP data transfer is not a new subject [1, 2, 3] In Drushel and Peterson [1] the authors proposed a fbuf (fast buffer) ....

....that the packet processing time has two components [15] ffl a fixed service time that is independent of the packet size, ffl an incremental service time that is proportional to the packet size. The fixed service time appears at almost every layer of the communication architecture and includes [3, 14]: the overhead associated with memory management, interrupt processing and context switching, and the propagation delay of a packet on the communication network. The incremental service time is mainly due to [3, 14, 15] data movement between different protocol layers, building CRC (or checksum) ....
....time appears at almost every layer of the communication architecture and includes [3, 14] the overhead associated with memory management, interrupt processing and context switching, and the propagation delay of a packet on the communication network. The incremental service time is mainly due to [3, 14, 15]: data movement between different protocol layers, building CRC (or checksum) when the packet is sent and verifying it when the packet is received, transmission of the packet on the communication network. As an example, consider a distributed application consisting of three processes running on ....

....based on the measurement shown in Table 1, the data copying part of a TCP based data transfer session consumes between 45.4 to 68 CPU resource, assuming the session s throughput is 50 MBytes sec. This is in addition to other CPU consuming tasks, such as network interrupt handling, TCP processing [4], NFS protocol handling, iSCSI processing and other related system tasks. Adding these tasks together will easily saturate the CPU and thereby degrade the overall throughput of NFS servers that are based on iSCSI storage. An effective solution to the performance problem of iSCSI based NFS ....
