Problems solved by technology

[0007] In the link resource management method above, when dividing the attributes of links shared by a specific group of VPNs, it is realized by publishing the maximum number of sharing times of the V-LSP. The defect is that the shared VPN group actually formed in this way It is completely random and cannot be processed according to the characteristics of the actual business object. The attributes of the divided link resources may be unreasonable, and the transmission network resources cannot be used accurately and effectively.

Embodiment 1

[0028] Embodiment 1. A link resource management method, such as figure 2 shown, including,

[0029]A1. The source network edge device receives a link resource reservation indication for a specified object, where the link resource reservation indication includes the resource reservation path attribute corresponding to the object and the identifier of the object group to which the object belongs;

[0030] Similar to the existing link resource reservation process, the source network edge device starts the reservation division process according to the received resource reservation instruction. In the present invention, in addition to the resource reservation path attributes required to establish the virtual link in the existing indication, the indication also needs to include the object group identifier (GID, Group ID) to which the resource request object belongs.

[0031] The resource reserved path attribute is the basic identification attribute of the reserved path, which may ...

Embodiment 2

[0075] Embodiment 2. A transport network, including a network edge device and a path computation unit,

[0076] The network edge device is configured to receive a link resource reservation indication for a specified object, where the link resource reservation indication includes the resource reservation path attribute corresponding to the object and the identifier of the object group to which the object belongs; The unit sends a request to calculate the resource reservation path of the object; according to the resource reservation path calculated by the path calculation unit, the link resource is reserved for the object according to the link resource sharing of the same group of objects; the reserved Publish link resource information to other network edge devices in the network;

[0077] The path calculation unit is configured to receive the calculation request sent by the network edge device, and calculate the resource reservation path of the object according to the resource ...

Embodiment 3

[0078] Embodiment 3. A network edge device, such as Figure 4 As shown, it includes a control interface unit 1, a path request unit 2, a resource reservation unit 3, and an information diffusion unit 4;

[0079] The control interface unit 1 is configured to receive a link resource reservation indication for a specified object, where the link resource reservation indication includes the resource reservation path attribute corresponding to the object and the identifier of the object group to which the object belongs;

[0080] The path request unit 2 is configured to send a request for calculating the resource reservation path of the object according to the link resource reservation indication received by the control interface unit 1, receive the calculated resource reservation path and send it to the resource reservation unit 3 ;

[0081] The resource reservation unit 3 is configured to reserve link resources for the objects according to the resource reservation path sent by th...

Abstract

The invention discloses a link resource management method, and the core idea thereof is to carry out the link resource pre-reserve according to the groups of the resource requested objects and the strategy of sharing the resources as far as possible of the same group of the objects. The path calculation unit in the invention for the implementation of the pre-reserved path calculation can adopt the distributing type and be arranged on various network edge equipments; which can also adopt the centralized type, at the same time, the refreshment of the resource pre-reserved information is also needed to be distributed to the centralized type path calculation unit. The invention also provides a transmission network and the related network equipment which are applied in the method, including network edge equipments and the path calculation unit. As the invention carries out the shared processing of the pre-reserved resource according to the determined object groups, the objects can make full use of the divided shared resource after the group division according to the actual characteristics, the division of the link resource can be more reasonable and accurate, and the invention can achieve the effects of improving the utilization ratio of the transmission network resource, improving the efficiency of operators and decreasing the expenses of business users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a link resource management method, a transmission network and related network equipment applied to the method. The present invention is applicable to link resource management in virtual private network (VPN, Virtual Private Network) or virtual network topology (VNT, Virtual Network Topology) and the like. Background technique [0002] In a virtual network, especially in a virtual network that realizes physical isolation through the control and allocation of data links, how to accurately and reasonably divide and manage link resources is the need to improve the efficiency of transmission network usage and effectively utilize network resources. important issues to solve. [0003] Taking Layer 1 Virtual Private Network (L1VPN, Layer 1 Virtual Private Network) business as an example, the general structure of L1VPN network is as follows: figure 1 As shown, it usually ...
