Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] In this embodiment, a policy routing processing method and device are provided, figure 1 is a flowchart of a policy routing processing method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0028] Step S102, the interface module reports the detected interface failure information to the protocol layer, wherein the interface failure information is used to instruct the protocol layer to update the status of the policy routing forwarding table to invalid;

[0029] Step S104, the interface module invalidates the PBR forwarding table corresponding to the failed interface.

[0030] Further, the protocol layer delivers the ...

Abstract

The invention provides a strategy routing processing method, a message forwarding method, and a strategy routing processing device and a message forwarding device. The strategy routing processing method comprises the steps of reporting detected interface failure information to a protocol layer, wherein the interface failure information is used for instructing the protocol layer to update the state of a strategy routing forwarding table to be invalid; and setting the strategy routing forwarding table corresponding to a failed interface to be invalid. According to the method and the device provided by the invention, the problem of packet loss caused by a forwarding table maintenance mode in related technologies is solved, and the possibility of packet loss is reduced.

Description

technical field [0001] The invention relates to the field of data network communication, in particular to a strategy routing processing method and device. Background technique [0002] Compared with traditional routing, policy routing has stronger functions and more flexible use. It enables network managers to select forwarding paths not only based on destination addresses, but also based on packet applications or source IP addresses. The so-called message application includes the interface number of Transmission Control Protocol (TCP) or User Datagram Protocol (UDP), and also includes the length of the message. Policy routing can realize traffic engineering to a certain extent, so that flows with different quality of service or data of different nature, such as voice traffic and data traffic, take different paths. [0003] As the policy routing technology is more and more widely used in the network, the requirements for policy routing are getting higher and higher. For exa...
