Problems solved by technology

However, with the development of the Internet, new services and new requirements continue to emerge. The virtual private network requires a dedicated network layer protocol at the network layer. The original data plane packet forwarding method is no longer applicable, which brings great challenges to packet forwarding. inconvenient

Embodiment 1

[0054] figure 1 It is a schematic flowchart of a message forwarding method proposed in the first embodiment of the present invention. The method includes the following steps:

[0055] Step S110, analyzing the received message to obtain key information of the message.

[0056] Wherein, the key information includes information such as destination address, VPN identifier, virtual private line label, packet forwarding priority, source port, destination port, and incoming interface. The destination address includes an area identifier and a device name.

[0057] The message may include a PPP (Point-to-Point Protocol) message, an Ethernet message, a FR (Frame Relay Protocol) message, etc. of the key information.

[0058] The message is parsed to obtain message header information, and the key information is obtained according to the information in the message header.

[0059] Step S120, judging whether the message is a message to the current device.

[0060] When the destination ...

Embodiment 2

[0081] Figure 2a to Figure 2b It is a schematic flowchart of a message forwarding method proposed in the second embodiment of the present invention.

[0082] Step S210, analyzing the received message to obtain key information of the message.

[0083] This step is the same as step S110 in Embodiment 1, and will not be repeated here.

[0084] Step S220, judging whether the area identifier of the destination address is the same as the area identifier of the current device and whether the device name of the destination address is the same as the device name of the current device.

[0085] Compare the acquired destination address with the address of the current device, and judge whether the region identifier of the destination address is the same as the region identifier of the current device and whether the device name of the destination address is the same as the device name of the current device. If the region identifiers of the devices are the same and the device name of the...

Embodiment 3

[0123] image 3 It is a schematic structural diagram of a message forwarding device proposed by an embodiment of the present invention. The message forwarding apparatus 400 corresponds to the message forwarding method in Embodiment 1, and any optional items in Embodiment 1 are also applicable to this embodiment, and will not be described in detail here.

[0124] The packet forwarding device 400 includes: an analysis and acquisition module 410 , a first judgment module 420 , a processing module 430 , a second judgment module 440 , a first acquisition and forwarding module 450 and a second acquisition and forwarding module 460 .

[0125] The parsing and obtaining module 410 is configured to parse the received message and obtain key information of the message, wherein the key information includes at least a destination address, a VPN identifier, and a virtual private line label.

[0126] The first judging module 420 is configured to judge whether the packet is a packet destined ...

Abstract

The invention discloses a message forwarding method and routing equipment. The method comprises the following steps: analyzing a received message, so as to acquire key information of the message; judging whether the message is a message sent to the equipment according to a target address; if so, sending the message into a control panel for analysis; otherwise, judging whether a virtual special line label is valid, if the message is valid, acquiring outlet interface information of the message according to the virtual special line label and a VPN identifier, and forwarding the message in a virtual special line network according to the outlet interface information; and if the message is invalid, acquiring forwarding information and outlet interface information of the message according to theVPN identifier and the target address, and forwarding and processing the message in a common network according to the forwarding information and the outlet interface information. The invention discloses the method for forwarding a network layer protocol message for combining the forwarding of the virtual special line network and the common network, the method can meet multiple forwarding demands,and the diversity of message forwarding ways is added.

Description

technical field [0001] The invention relates to the technical field of data network communication, in particular to a message forwarding method and routing equipment. Background technique [0002] With the development of network technology and the popularization of mobile Internet, people's life, work and study have become more and more inseparable from the Internet. A router (also known as a router) is a computer network device that can transmit data packets to a destination (select a data transmission path) through a network. This process is called routing. A router is a device that connects two or more separate networks. It works on the third layer of the OSI model—that is, the network layer, such as the Internet Protocol (Internet Protocol, IP) layer, and mainly completes IPv4 (Internet Protocol version 4, Internet Protocol version 4). , IPv6 (Internet Protocol version6, Internet Protocol version 6), MPLS (Multi Protocol Label Switch, multi-protocol label switching) and...
