Problems solved by technology

[0003] However, as the routes of ASs are visible to each other across the country, and the SRGB label resources of border routers are limited, if there are not enough SRGB labels to allocate, the same incoming label may correspond to different outgoing labels, and then there will be Different next-hop addresses and different outgoing interface information, which makes the border router unable to forward data packets normally

Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0027] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0028] Below, introduce the inventive concept of the present invention: all deploy one or more boundary routers in each AS, each boundary router places the label information of...

Abstract

The invention discloses a data forwarding method and a router, relates to the technical field of communication, and is used for successfully forwarding data between autonomous systems AS. The method comprises the steps: obtaining a stack top label in a to-be-forwarded data packet; if a plurality of outgoing tags exist in the current tag forwarding table LFIB, obtaining a target internet protocol IP address, wherein each output label in the plurality of output labels corresponds to the stack top label, and the target IP address is a target IP address of the to-be-forwarded data packet; determining a target outgoing label from the outgoing labels according to the target IP address, wherein the target outgoing label forwards a label used by the to-be-forwarded data packet; and updating the to-be-forwarded data packet according to the target outgoing label, and sending the updated data packet. The embodiment of the invention is applied to sending the data packet between the ASs.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data forwarding method and a router. Background technique [0002] Currently, border gateway protocol (border gateway protocol, BGP) is usually used between different autonomous systems (autonomous system, AS) to select routes between border routers of the AS. Specifically, after a border router receives the data packet sent by the previous hop border router, it can obtain the outgoing label from the label forwarding table (label forwarding information base, LFIB) according to the incoming label carried by the stack top of the data packet. And use the outgoing label to replace the incoming label in the top of the stack, and send the data packet to the next-hop border router according to the next-hop address and outgoing interface information corresponding to the outgoing label, so as to realize the reachable routing of the data packet. Wherein, the incoming label include...
