Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, for a multi-layer and multi-domain routing domain, no matter how complex the structure is, it is always passed by a single domain figure 1 The several operations shown are evolved step by step. exist figure 1 In , the domain on the left always precedes the domain on the right in time, so we call the domain on the left the front domain and the domain on the right the posterior domain. At the same time, the field on the right is always introduced by the field on the left through some operation, and the field on the right must depend on the field on the left to exist. Therefore, we can use an identical relation to express the generation relationship between routing domains:

[0031]

[0032] Therefore, each routing domain of a multi-layer multi-domain routing domain, from the perspective of evolut...

Abstract

The invention discloses a method for naming and analyzing a subnet point pool in an automatically switched optical network, which relates to a naming and analysis method for transmission network resources. The invention can dynamically adapt to variation of the routing domain in order to realize that analysis of an SNPP, thus meeting requirements for actual operation of the network. The method includes the following steps: (1) an alias name of the subnet point pool is deduced from a genuine name of the subnet point pool and a relation chain between the genuine name of the subnet point pool and the alias name of the subnet point pool is established; (2) mapping of the alias name of the subnet point pool to the genuine name of the subnet point pool is established; and (3) mapping relationship between the alias name of the subnet point pool and a physical transmission resource is established. Starting with evolution of a routing domain, the invention obtains relationship among the routing domains over different layers and domains, educes the SNPP naming educing relation chain among the nodes in different routing domains and proposes an SNPP naming and analysis scheme, thus effectively solving a problem that the same node in different routing domains is subject to multiple names.

Description

technical field [0001] The invention relates to a method for naming and analyzing transmission network resources, in particular to a method for naming and analyzing a subnet point pool of an automatic switching optical network. Background technique [0002] SubNet Point Pool (SNPP: SubNet Point Pool) and SNPP Link are the reflections of the transmission resources of a transmission node on the control plane by the Automatic Switched Optical Network (ASON: Automatic Switched Optical Network), and are used for routing calculation and routing information diffusion on the control plane. The basis of SNPP, the naming of SNPP is the identification of SNPP. [0003] In an ASON network with a single layer and a single routing domain, since all routing nodes belong to only one routing domain, any routing node has and can only have one identifier in the entire routing domain, so it belongs to a specific SNPP of a certain node Only one named identifier is required in the fully routed d...
