Embodiment 1

[0029] Please refer to figure 1 As shown, the message forwarding configuration method of the communication device provided in this embodiment includes:

[0030] S101: The interface module of the communication device writes the next hop table of the narrowband interface; One hop table; it should be noted that the communication equipment in this solution mainly includes devices that can complete the three-layer forwarding function of messages, including routers, switches, etc.; the content of the next hop table includes: next hop hardware table , and the encapsulation information and forwarding information of the narrowband message; the narrowband message on the link does not have an Ethernet header, but in the forwarding device, in order to share the common forwarding process, after the message enters the device, the FPGA (Field-Programmable Gate The Array Field Programmable Gate Array) module will encapsulate the Ethernet header on the message and send it to the forwarding mo...

Embodiment 2

[0036] The present invention also provides a message forwarding method. The communication device is configured according to the configuration method described in any one of the above embodiments; the communication device forwards the message according to the configuration. In this embodiment, specific message forwarding method steps include:

[0037] Step 1, the communication device is configured according to the configuration method; the specific configuration process includes: the interface module of the communication device writes the next hop table of the narrowband interface, the routing module of the communication device obtains the routing table, and judges its route according to the routing table When the egress is the narrowband interface, establish an association with the next hop table in the routing table;

[0038] Step 2: The communication device forwards the message according to the configuration; since the destination address in the message is often a host address...

Embodiment 3

[0040] Please refer to figure 2 As shown, the communication device 20 provided in this embodiment includes an interface module 201 and a routing module 202; the interface module 201 is used to write the next hop table of the narrowband interface; the routing module 202 is used to obtain the routing table, and according to When the routing table judges that the routing egress is the narrowband interface, an association with the next hop table is established in the routing table. It should be understood that, during the creation process of the narrowband interface of the communication device 20, the next hop table of the narrowband interface is written in the interface module 201 of the communication device 20; A device with a three-layer forwarding function, including a router, a switch, etc.; the content of the next hop table includes: a next hop hardware table, and encapsulation information and forwarding information of narrowband packets; after the routing protocol negotiat...

Abstract

The invention discloses a message forwarding configuration method and device for communication equipment, and a message forwarding method. The message forwarding configuration method comprises that an interface module of the communication equipment writes in a next skip list of a narrow-band interface; a route module of the communication equipment obtains a routing table, and builds the correlation with the next skip list in the routing table when the routing outlet of the routing table is judged to be the narrow-band interface. The message forwarding configuration method solves problems, caused by that the configuration of the narrow-band interface needs the strong correlation between the interface modules and a routing modules, of complexity among modules and fault positioning difficulty in the prior art, reduces the complexity among the modules in the communication equipment, and simplifies the forwarding process of the narrow-band interface.

Description

technical field [0001] The invention relates to the field of data communication of communication equipment, in particular to a message forwarding configuration method and device of communication equipment and a message forwarding method. Background technique [0002] On communication devices such as routers or switches, Layer 3 forwarding is mainly based on route forwarding, and the egress of the message and the modification policy of the message header can be found for the message through the route and the next hop. However, on an existing router or switch, there are at least two types of interfaces for packet forwarding, including an Ethernet interface and a narrowband interface. The differences between the narrowband interface and the Ethernet interface mainly include: the Layer 3 forwarding of the Ethernet interface is connectionless, so one egress may correspond to multiple next hops, while the Layer 3 forwarding of the narrowband interface is generally connection-orien...
