Problems solved by technology

[0005] However, in the above process, when determining the traffic forwarding path according to the routing table information in the network, it is necessary to learn a complex routing iterative algorithm, and the routing iterative algorithm is often configured according to the routing policy of the routing device in the network. The routing strategy used is complex and changeable. Therefore, it is difficult to restore the routing track consistent with the real forwarding path of the routing device by using the above method.

Embodiment 1

[0051] An embodiment of the present invention provides a method for restoring a flow forwarding path, such as figure 2 As shown, the restoration method of the flow forwarding path includes:

[0052] S101. The network flow device obtains the port IP address of each of the at least two routing devices in the network, and determines the connection relationship between the ports of the at least two routing devices according to the obtained IP addresses. If there is a connection relationship The subnet mask in the IP address of both ports is the same.

[0053] Wherein, the port IP address of a routing device includes the IP address of each port of at least two ports of the routing device. The network flow device may obtain, from each routing device in the network, each of the at least two ports of the routing device.

[0054] Exemplarily, the network flow device may collect routing configuration information of the corresponding routing device from the routing device in the netwo...

Abstract

The embodiment of the invention discloses a method and device for restoring a flow forwarding path, relates to the field of communication technology, and can restore a service flow forwarding path with a high similarity to a real forwarding path. The specific scheme is: obtain the port Internet Protocol IP address of each routing device in at least two routing devices in the network, and determine the connection relationship between the ports of the at least two routing devices according to the obtained IP address; obtain at least two The statistical flow transmission information of each routing device in the routing devices; according to the connection relationship between the ports of at least two routing devices and the obtained statistical flow transmission information, determine each first service flow in the at least one first service flow A flow forwarding path, the first service flow is composed of at least two statistical flows flowing into ports with a connection relationship, and the address information of the statistical flows in the first service flow is the same.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for restoring a flow forwarding path. Background technique [0002] With the rapid development of services such as mobile broadband and data centers, the pressure on the operator's network is increasing; and the expansion of the operator's network is becoming more and more difficult. During the expansion of the operator's network, local network congestion often occurs. [0003] Among them, the operator needs to restore the (Internet Protocol, IP) service route in the network, that is, analyze and obtain the traffic information of each segment of the route and the routing track of each traffic, so as to avoid network congestion in the operator network. [0004] In the prior art, the IP service routing can be restored in the following way: collect statistical flow information (including traffic size) at the network entrance, and determine the traf...
