Method for establishing hard pipe as well as method and device for transmitting messages in network

Abstract

The invention discloses a method for establishing hard pipe as well as a method and a device for transmitting messages in a network. The network comprises a plurality of routers and an NMS (network management system). The method comprises the following steps: the NMS acquires the bandwidths of all links in the network; the NMS informs the routers in a network topology of dividing fixed bandwidths in the link bandwidth of the network topology, a sublink is formed by the link for dividing into the fixed bandwidths, and a hard pipeline plane used for bearing a private line service is formed by the sublink and the routers which divide the sublinks; a static MPLS (Multi Protocol Label Switching) label integration is distributed to the hard pipeline plane by the NMS, and the label of the MPLS label in the static MPLS label integration can be transferred by the hard pipeline plane only, therefore, a private line service can be borne in the hard pipeline plane, the bandwidth of the private line service cannot be occupied by other non-private line services, and the private line service which ensures the bandwidth can be provided.

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, ...

AI Technical Summary

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.
