Problems solved by technology

[0004] However, the rate at which the CPU sends packets to the SDH interface device is far greater than the rate at which the SDH interface device forwards packets to other devices, making the SDH interface device lose packets because it cannot forward packets exceeding its own forwarding rate.

Abstract

The application provides a message issuing method and forwarding equipment. The method comprises the following steps: determining a target SDH port corresponding to a to-be-issued target message by aCPU, adding feature information for indicating target message forwarding in the target message if the value of the recorded residual variable corresponding to the target SDH port is greater than target message length, issuing the target message added with the feature information to a logic device, and reducing the target message length from the value of the residual variable; stripping the featureinformation from the target message by the logic device, sending the target message to the target SDH port to forward after the feature information is stripped, and computing the forwarding durationof the target message based on the feature information, and indicating the CPU to add the target message length on the value of the residual variable when computing the forwarding duration and after passing through the forwarding duration, thereby limiting a rate of issuing the message to the SDH port by the CPU, and preventing the packet loss.

Description

technical field [0001] The present application relates to the field of computer communication, and in particular to a message delivery method and a forwarding device. Background technique [0002] POS: (Packet Over SONET / SDH, based on SONET / SDH bearer network IP packets) technology refers to a high-speed transmission channel directly provided by SONET (Synchronous Optical Network) / SDH (Synchronous Digital Hierarchy) A technology for transmitting IP (Internet Protocol, Internet Protocol) packets. [0003] The forwarding equipment using POS technology usually includes CPU, logic device and SDH interface device. When the CPU sends a message to the SDH interface device, the CPU can transparently transmit the message to the logic device, and then the logic device sends the message to the SDH interface device, and the SDH interface device can forward the message to other devices. [0004] However, the rate at which the CPU sends packets to the SDH interface device is far greater...
