Abstract

The invention provides a network packet header compression method and a network packet header compression device used for network performance monitoring. The method comprises: the position informationof a transmitting device of a current network data package is obtained; if it is judged that the location information indicates that the transmitting device is located at an access location in the network, the packet header of the current network data packet is compressed based on the obtained terminal server physical address list. The invention provides a network data packet header compression method and a network data packet header compression device for network performance monitoring, which compress based on the physical address or the IP address granularity of the network data packet header according to the position of collecting the network data packet, thereby realizing higher compression ratio. The invention also reduces the bandwidth and storage space consumption in the process ofcollecting, transmitting and storing network packet headers when network performance is monitored, and reduces the fault tolerance of decompression.

Description

technical field [0001] The invention relates to the technical field of network monitoring, in particular to a network data packet header compression method and device for network performance monitoring. Background technique [0002] Network Performance Monitor (NPM) needs to analyze network data packet headers, which involves collection, transmission and storage of network data packet headers. In the transmission and storage stages, how to efficiently compress network data packet headers is the key to reducing bandwidth consumption and storage space. [0003] In the prior art, the sFlow technology is used for network monitoring. The sFlow technology does not compress the packet header during the collection, transmission and storage of the network data packet header. Since both IP and TCP can carry optional fields of up to 40 bytes, Therefore, when using sFlow technology for traffic collection, it is necessary to intercept at least 138 bytes of network data packets, of which...
