Data forwarding method, device, equipment and storage medium

Abstract

The embodiment of the present invention discloses a data forwarding method, device, device, and storage medium, wherein the method includes: the first device searches the forwarding path table of the first device for the first prefix label associated with the private network address , the forwarding path table of the first device includes one or more private network addresses, and a prefix label associated with each private network address, and the first device uses the first prefix label, data content, and the private network address encapsulated into a first data packet, the first device sends the first data packet to a second device corresponding to the first prefix label, the first data packet is used to obtain a second data packet, and the second data packet The text is obtained by encapsulating the second prefix label, data content and private network address, and the second prefix label is associated with the private network address, which can realize data forwarding between the base station side gateway and the wireless service side gateway.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a data forwarding method, device, equipment and storage medium. Background technique [0002] IP-based wireless access network (Internet Protocol Radio Access Network, IPRAN) is a router / switch overall solution optimized and customized for IP (Internet Protocol, network protocol) base station backhaul application scenarios. With the continuous advancement of network IP , IPRAN is becoming more and more important for mobile networks. In IPRAN networking, usually the base station gateway and the wireless service gateway establish an end-to-end route to implement data forwarding between the base station gateway and the wireless service gateway. However, between the base station gateway and the wireless service gateway When data is forwarded through the prefix label, if the destination prefix label is not in the local forwarding path table of the gateway on the base station...

Problems solved by technology

[0005] In this technical solution, the first device can search the next hop address (that is, the first prefix label) for the first device to reach the private network address in the path forwarding table of the first device, and use the first prefix label, the private network address and The data content to be sent is encapsulated into a first data packet, and the first data packet is sent to the second device corresponding to the first prefix label, and the second device can search the second device in the forwarding path table of the second device to reach the private The next hop address of the network address (that is, the second prefix label), the first prefix label in the second data message is replaced by the second prefix label to obtain the second data message, and the second device sends the second data message To the third device corresponding to the second prefix label, the data forwarding between the first device and the third device can be realized by exchanging the prefix label, which can solve the problem that the prefix label of the third device is not in the forwarding path table of the first device , the problem that data forwarding cannot be realized between the first device and the third device
