Hard pipe building method, packet forwarding method and device in network

Abstract

The embodiment of the invention discloses a hard pipe building method, a packet forwarding method and device in a network. The network comprises a plurality of routers and a network management system. The hard pipe building method in the network comprises the following steps: obtaining bandwidth of all links in the network through the network management system; informing a router in a network topology of dividing fixed bandwidth from the link bandwidth of the network topology through the network management system; enabling the links with the fixed bandwidth divided to form a sub-link; enabling the sub-link and the router with the sub-link divided to form a hard pipeline plane for bearing private line service; distributing static MPLS (Multi Protocol Label Switching) label set to the hard pipe distributing plane through the network management system. According to the hard pipe building method, the packet forwarding method and device in the network, a service message with an MPLS label in the static MPLS label set can only be forwarded through the hard pipeline plane, so that the hard pipeline plane is only to bear the private line service, and the bandwidth for the private line service cannot be occupied by other public line services, and as a result, the private line service with the bandwidth ensured is brought.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for establishing a hard pipe in a network, a method and a device for forwarding messages. Background technique [0002] Currently, two types of services mainly provided by network operators in the network are leased line (Leased Line) services and common broadband services, and these two types of services share network bandwidth. [0003] In order to ensure the bandwidth of all services in the network, especially the bandwidth of dedicated line services, network operators will set the total bandwidth in the network to be much larger than the sum of the bandwidth of all services in the network. This way of setting bandwidth is generally called High bandwidth mode. [0004] The disadvantage of the large bandwidth method is that although the total amount of network bandwidth is set relatively large, the dedicated line service and other services still share the network bandwidth, ...

Problems solved by technology

[0004] The disadvantage of the large bandwidth method is that although the total amount of network bandwidth is set relatively large, the dedicated line service and other services still share the network bandwidth, so that the bandwidth of the dedicated line service is often occupied by other services, resulting in the loss of the dedicated line service. The bandwidth is unstable, and the effect of ensuring stable bandwidth that the private line service should have achieved cannot be achieved.
