The embodiment of the invention discloses a route establishing method, a carrying network router and a network system. The route establishing method comprises the following steps: receiving data; determining a forwarding route for a data stream according to recorded network route information of the service carrying network; and establishing a label switching route through an explicit route according to the forwarding route, wherein the explicit route records carrying network routers and an ordinary router between the carrying network routers, through which the data stream passes when being forwarded. The embodiment of the invention correspondingly provides the carrying network routers and the network system. The technical scheme of the embodiment of the invention can better realize dynamic balance of network link loads.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a path establishment method, a bearer network router and a network system. Background technique [0002] With the continuous development of network technology, the requirements for building high-performance networks are becoming more and more urgent, so the development of high-speed routing and forwarding systems has become a more important issue. Based on this requirement, Multiprotocol Label Switching (Multiprotocol Label Switching, MPLS) technology emerges as the times require. [0003] MPLS technology is an emerging Internet Protocol (IP) backbone network technology, which provides a high-speed and efficient connection-oriented data transmission in the backbone network through the introduction of the label concept on the connectionless IP network. the transmission method. MPLS technology has the advantages of fast forwarding, support for explicit routing, etc., guaran...
