Embodiment Construction

[0028] The design idea of ​​the present invention is: abandon the consistent processing idea of ​​configuring the address information table on the convergence layer device, directly extract the address information such as the source IP address and the source logical port number from the request message sent by the access layer device, and After they are stored in the Proxy-State attribute domain of the request message, they are forwarded to the backbone layer equipment. The prerequisite for the realization of the present invention is to ensure that the backbone layer equipment does not perform any processing on the information carried by the Proxy-State attribute domain of the request message; therefore , when the response message is fed back from the backbone layer device to the aggregation layer device, the address information such as the IP address and logical port number of the access layer device can be directly obtained from the Proxy-State attribute field of the response ...

Abstract

This invention discloses a message interactive method for increasing the repeating property, which comprises the following steps: a) the syntaxis layer device will enclose the address information of the switch-in layer in the requirement message sent by the switch-in layer in the proxy condition attribute area, and then sending to the backbone layer device; b) the backbone layer device will receive the requirement message, enclosing the address information in the proxy condition attribute area of the response message, then sending to the syntaxis layer device; c) the syntaxis layer device will return the response message to the switch-in layer device.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a message interaction method applied between an access layer device and a convergence layer device to improve the forwarding performance of the device. Background technique [0002] With the rapid development of Internet technology, the network structure of the network system is becoming more and more complicated. As shown in Figure 1, this figure is the basic network structure topology diagram of the existing network system; Layer 1, aggregation layer 2, and backbone layer 3 form a three-layer network framework structure, in which the number of network nodes in backbone layer 3 is relatively small, usually including some backbone layer devices such as business servers and backbone routers; the main task of aggregation layer 2 is A large number of access layer devices 11 in the access layer 1 are connected to the corresponding backbone layer devices in the backbone lay...
