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.

Embodiment 1

[0077] refer to figure 1 , figure 1 It is a flowchart of a method for establishing a hard pipe plane in a network provided by an embodiment of the present invention. The network includes multiple routers and a network management system, and among the multiple routers, adjacent routers are connected by links with a certain bandwidth. , the multiple routers form a network topology through the links. This embodiment will describe how to establish a hard pipe plane in the network from the side of the network management system in the network.

[0078] like figure 1 As shown, the method includes:

[0079] S101: The network management system acquires bandwidth of all links in the network.

[0080] S102: The network management system notifies the routers in the network topology to divide the fixed bandwidth in the link bandwidth of the network topology, divide the links with the fixed bandwidth to form sub-links, and divide the sub-links into the sub-links. Link routers form a ha...

Embodiment 2

[0109] The embodiment of the present invention is based on the embodiment of the present invention—from the side of the router in the network to describe how to forward the service packets of the leased line service, Figure 5 It is a flowchart of a method for forwarding messages in a network provided by an embodiment of the present invention, the network includes a first router, a second router, and a network management system, and the method includes:

[0110] S501: The first router receives a label forwarding entry issued by the network management system, the label forwarding entry includes a static MPLS label, and the label forwarding entry is used to establish a hard pipe from the first router to the second router , the hard pipe is an LSP or PW from the first router to the second router.

[0111] S502: The first router receives the service packet of the leased line service sent by the user, and encapsulates the static MPLS label and the leased line label corresponding to...

Embodiment 3

[0120] refer to Image 6 , Image 6 A flow chart of a method for establishing a hard pipe in a network provided by an embodiment of the present invention. The network includes multiple routers and a network management system, and among the multiple routers, adjacent routers are connected by links with a certain bandwidth. This embodiment will describe how to establish a hard pipe in the network from the side of the network management system in the network.

[0121] like Image 6 As shown, the method includes:

[0122] S601: The network management system obtains the bandwidth of all links between the first router and the second router, the first router is one of the multiple routers, and the second router is one of the multiple routers of a router.

[0123] Please refer to Example 1 for this step figure 1 The related description of S101 in the illustrated embodiment will not be repeated here.

[0124] S602: The network management system determines a static MPLS label set....

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, ...
