System and a method for routing traffic in an MPLS network

A method for use in an MPLS network by a managing entity comprises in a routing element, wherein said routing element is configured to share one or more circuits among multiple Intermediate System to Intermediate System (IS-IS) routing protocol instances, and wherein each of the routing protocol instances is dynamically associated with a database selected from among a plurality of databases, said method comprising the steps of:

• managing a plurality of traffic engineering software agents, and to dynamically select a database from among the plurality of databases, to be associated with a traffic engineering software agent from among said plurality of the traffic engineering software agents, wherein said traffic engineering software agent is used for conveying traffic along a path being currently used for conveying traffic, and wherein said selection of a database is made based on an ad hoc selection of a database from among the plurality of databases,
• updating databases associated with respective routing protocol instances and based on that update, to allocate available resources to routing protocol instances via which traffic is being conveyed;
• and
• conveying traffic via a specific routing protocol instance, wherein said specific routing protocol instance is associated with the one or more databases currently selected from among the plurality of databases.
