A router advertises an aggregated service or route that can be evaluated by other routers as
a unitary segment rather than as a group of individual links/paths associated with the …

Techniques are described for selecting paths in accordance with service level agreements.
For example, spoke and hub routers may advertise routes associated with virtual routing and …

BACKGROUND Generally described, computing devices utilize a commu nication network,
or a series of communication networks, to exchange data. In a common scenario, data to be …

Link failure messages are sent through a network to accelerate convergence of routing
information after a network fault. The link failure messages reduce the oscillations in routing …

A router can consider two color vectors for a path including multiple links through a network.
One color vector indicates colors that all of the multiple links include. Another color vector …

TIME (SEC) 0 1 2 embodiments, the router (101, 103, 105) can facilitate calcu lating an
alternate path for routing the packet (107a-107f.) received from the communication interface …

Techniques are described for selecting paths in accordance with service level agreements.
For example, spoke and hub routers may advertise routes associated with virtual routing and …

In general, techniques are described to dynamically redefine a preference value used
during route resolution. A network device, such as a router, may implement the techniques to …

BACKGROUND Routing devices within a network, often referred to as routers, maintain
routing information that describe available routes through the network. Upon receiving an …

In exemplary embodiments of the present invention, a router determines whether or not to
establish a stateful routing session based on the suitability of one or more candidate return …
