Editing Path computation element, also associated with an entity that performs Routing Computation
{{context|date=July 2008}}
Routing is the process of finding a suitable route for conveying data between a source and one or a set of destination. Routing can be subject to a set of constraints, like QoS, policy, or price. Constraint-based path computation is a strategic component of traffic engineering in [[MPLS]] and [[GMPLS]] networks. It is used to determine the path through the network that traffic should follow, and provides the route for each [[Label Switched Path]] (LSP) that is set up.
