Embodiment Construction

[0051] To solve the problem in the prior art that the steps of determining the data flow site are complicated, the source PE in the embodiment of the present invention receives the data flow from the source CE, and determines the The destination site of the data flow, thereby solving the above-mentioned problem.

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] As shown in Figure 3A, the method for determining the data flow site in the embodiment of the present invention includes the following steps:

[0054] Step a300, the source PE receives the data stream from the source CE.

[0055] Step a301: Determine the source site of the data flow according to the interface index bound to the VRF and the IP address of the source PE obtained from the data flow.

[0056] Step a302: Determine the destination site of the data stream according to the IP address of the destination PE obtained from the data stre...

Abstract

The method comprises: the source provider edge (PE) device receives the data stream from source client edge (CE) device, and according to the IP address of destination PE obtained from the stat stream and the inner layer label allocated for the destination site by the destination PE, confirms the destination site of the data stream.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and device for determining data flow sites and flow statistics. Background technique [0002] With the rapid development of the network, the traffic in the network is also increasing day by day. In a virtual private network (Vrtual Private Network: VPN), it is necessary to be able to accurately determine the data flow site (Site) in the VPN, so that the traffic status between different sites can be understood, and different sites can be billed, monitored, and so on. [0003] For example, currently, there are two ways to determine the data flow site: [0004] As shown in FIG. 1 , in the existing schematic diagram of determining a data flow site based on Simple Network Management Protocol (SNMP), [0005] The traffic index based on SNMP can only collect the data traffic flowing in or out of the interface of Site1 or Site2 within a unit time. The desire to notify the s...
