Embodiment approach

[0063] Such as image 3 As shown, the specific processing steps of the packet receiving module are:

[0064] A101, register the packet receiving callback function, and dynamically configure the packet types counted by the flow sampling module, including Ipv4 and Ipv6 packets, and both Ipv4 and Ipv6 packets can carry Vlan and Mpls;

[0065] A102, set the ACL rule, monitor the PCIE interface and sample from the physical port, and receive the Ipv4 and Ipv6 messages obtained from the NP unit;

[0066] A103. Select the corresponding analysis function according to the message type to extract the message's own information. If it is an unsupported message type, the original message is directly discarded. The message's own information includes: source IP address, destination IP address, protocol type, ToS , source port, destination port, incoming interface, outgoing interface, IP version, Tcp flag, flow direction, packet arrival time, packet byte count, flow count, aggregation mode, I...

Abstract

The invention relates to an IP stream information statistical method for charging and monitoring. Flow statistical analysis is carried out on an IP data packet through a stream sampling module to obtain original, detailed and basic IP data streams flowing through a port, and the flow statistical analysis comprises message analysis, message information statistics, statistical information aging and collection and statistical information output. The stream sampling module is arranged in a common service board card, and comprises four submodules, namely, a packet collecting module, a statistical module, an aging and collection module and a communication module. The IP stream information statistical method can accurately grasp a network operating state, provides the accurate information of network flow in real time, can find and process network abnormal conditions in real time, can allow management and the charging for service application, helps network administers to carry out network planning, network monitoring and flow trend analysis, and achieves network visualization management.

Description

technical field [0001] The invention relates to the technical field of IP flow information statistics, in particular to a statistical method for IP flow information used for billing and monitoring. In particular, it refers to the traffic statistics analysis method for Ipv4 and Ipv6 flows with Vlan and Mpls label conversion. Background technique [0002] With the increasing number of services and applications supported by the network, users have put forward higher requirements for traffic statistics and analysis. Traditional traffic statistics and analysis such as SNMP (Simple Network Management Protocol, Simple Network Management Protocol), RMON (Remote Network Monitoring, remote network monitoring ) probe processing, etc., due to the inflexibility of statistical traffic methods or the need to invest in dedicated servers, etc., it cannot meet the needs of more detailed management of the network. A new technology is needed to better support network traffic statistical analysi...
