Abstract
A multi-protocol label switching system using multiple cores. In establishing a virtual private network in a MPLS system, more than one core is available. Paths are established over each core separately and weights are assigned to the two routes. Thus, the route which is preferred by manually configuring in advance will be chosen.
Claims11
A method for routing data packets through a system comprising:
- providing a plurality of cores;
- connecting a data input to each core by way of an edge router;
- determining a data path through each core;
- weighting each path;
- and
- selecting one path for data transmission.
3 more elements
An MPLS system for transporting data, comprising:
- a plurality of cores;
- at least one edge router for introducing data flow into each core;
- a plurality of routers in each core for establishing a data path in each core;
- wherein a weight for each path is manually inserted with one path being selected based on said weight.
