Problems solved by technology

After the interface board finds a piece of MTU information, it generates an RPC message and forwards it to the interface board that needs to be synchronized. Therefore, when the amount of MTU information is large, RPC messages need to be processed continuously and frequently, and the interface board cannot be used reasonably. computing resources

Abstract

The invention relates to the technical field of communication, in particular to a MTU information sending method and device, applied to a first interface board. The MTU information sending method comprises the following steps: step A, confirming a preset amount of maximum transmission unit MTU information carried by a remote procedure call protocol RPC message according to the current memory occupancy rate; step B, allocating memory for the RPC message carrying the preset amount of the MTU information; step C, storing the MTU information extracted from the MTU information linked list of the first interface board to the allocated memory to form the RPC message; and step D, sending the formed RPC message to a second interface board. The amount of the MTU information to be carried by the RPCmessage is confirmed for the MTU information based on the current memory occupancy rate, therefore, the memory can be allocated for the RPC message through the amount, and the computing resources of the interface board can be used more reasonably.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for sending MTU information. Background technique [0002] During multi-protocol label switching (Multi-Protocol Label Switching, MPLS) forwarding, a maximum transmission unit (Maximum Transmission Unit, MTU) needs to be configured on the interface of the routing device, so as to forward the ultra-long message in fragments. [0003] When configuring the MPLS MTU of an interface, each interface board will store the configured MPLS MTU information in a linked list. When configuring the protocol (Internet Protocol, IP) MTU and / or interface MTU between the networks of the interface, only the interface board where the configured interface is located responds to the configuration command, and the interface board creates another linked list for storage Configured IP MTU or interface MTU. The IP MTU or interface MTU needs to be synchronized bet...
