A link resource management method and transmission method and network device

Abstract

The invention discloses a link resource management method, the core idea of ​​which is to reserve the link resource according to the group to which the resource request object belongs, and according to the policy that the objects in the same group share resources as much as possible. In the present invention, the path calculation unit that performs reserved path calculation can be distributed and configured on each network edge device; it can also be centralized, and at this time, the update of resource reservation information also needs to be released to the centralized path calculation unit . The present invention also provides a transport network and related network equipment applied to the method, including network edge equipment and path calculation units. Since the present invention performs shared processing on the reserved resources according to the determined object groups, the objects can be grouped according to the actual characteristics, and the divided shared resources can be fully utilized, so that the division of link resources is more reasonable and accurate, and the transmission network can be improved. Resource utilization, improving operator benefits and correspondingly reducing the effect of business user expenditures.

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 ...

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.
