Method and system for management of network domains
First Claim
1. A method for management of a network domain formed from network elements interconnected with links, each link comprising at least one transport medium component, the method comprising steps of:
- a) providing an NMS (network management system) of the network domain;
b) providing a link attribute database associated with said NMS and incorporating link attribute data comprising a plurality of user attributes and values thereof assigned to each link existing in the network domain, c) applying to said link attribute database at least one instruction for processing said link attribute data according to at least one of said user attributes.

Abstract
A system and a method preferably intended for determining a path between a plurality of network domains in a network according to at least one path attribute. The path attributes are preferably stored in a database, and are used in order to determine a suitable path for data transport between the plurality of network domains. The particular desired outcome for selecting the path depends upon the nature of the path and the type of attributes which are selected for determining the path. Preferably, the system and method are employed for telecommunication networks, for example for connecting telephone exchanges and/or customer data equipment with service providers.

16. A system for routing a protected path between a plurality of network domains in a network, the network comprising at least a first network domain and a second network domain, the protected path comprising a main path and an alternate path, each of the main path and the alternate path being composed of a plurality of links forming respective path sections in the network domains, the system comprising:
-
(a) a first domain NMS (network management system) for managing the first network domain;
(e) a first link attribute database associated with said first domain NMS for storing link attribute data comprising a plurality of user attributes and values thereof assigned to each link existing in the first network domain;
(f) a second domain NMS for managing the second network domain;
(g) a second link attribute database associated with said second domain NMS for storing link attribute data comprising a plurality of user attributes and values thereof assigned to each link existing in the second network domain;
one of said NMS serving as a UNMS capable of maintaining consistency between said user attributes and values thereof in the first and second databases, and of applying to both of said network domains one instruction to determine in each of them a main path section and an alternate path section according to said at least one user attribute, said at least one instruction determining whether to include a particular link in any of the alternate path sections, such that none of the alternate path sections share a transport medium component used in any of the main path sections.
