The invention discloses a TCP (transmission control protocol) header compression method in wireless IPv6 network, belonging to the technical field of improving the compression ratio and robustness of a wireless link. The invention emphasizes the three compression states, three working modes, W-LSB (...
By opening and closing fewer TCP connections, CPU time is saved in routers and hosts (clients, servers, proxies, gateways, tunnels, or caches), and memory used for TCP protocol control blocks can be saved in hosts. HTTP requests and responses can be pipelined on a connection. Pipelining allo...
●Protocal(协议字段):占8比特,用来指出IP层所封装的上层协议类型,如传输层TCP/UDP/ICMP/IGMP。 ●Header checksum(头部校验和字段):占16比特,内容是根据IP头部计算得到的校验和码。计算方法是:对头部中每个16比特进行二进制反码求和。(和ICMP、IGMP、TCP、UDP不同,IP不对头部后的数据进行校验)。 ●source addres...
Protocol analyzers like wireshark will often use a relative sequence number of 0 since it’s easier to read than some high random number. Acknowledgment number: this 32 bit field is used by the receiver to request the next TCP segment. This value will be the sequence number incremented by ...

Three bits suffice: explicit support for passive measurement of Internet latency in QUIC and TCP The Internet measurement of round-trip time (RTT) is important as an indication of performance and latency. While the Ping utility can and does measure RTT... JS Edwards - 《Computing Reviews》 被...

To this end, a change was made in how the TCP checksum is computed. This special TCP checksum algorithm was eventually alsoadopted for use by the User Datagram Protocol (UDP). Instead of computing the checksum over only the actual data fields of the TCP segment, a 12-byte TCPpseudo heade...

"Protocol" field of IPv4 header The 8-bit "Protocol" field indicates the protocol that will receive the data payload. For example, ICMP (Internet Control Message Protocol) has a Protocol number of 1, TCP (Transmission Control Protocol) has a Protocol number of 6, UDP (User Datagram Protocol...
