Abstract
A router system implements a plurality of virtual routers. Various combinations of resources may be shared by the router system when implementing the virtual routers. In one embodiment, the particular combination of resources to share when implementing the virtual router is user programmable.
Claims20
A method comprising:
- allocating, by a processor of a single device, a set of logical resources between a plurality of virtual routers implemented in the single device;
- allocating, by the processor of the single device, a set of physical resources between the plurality of virtual routers implemented in the single device;
- and
- specifying, by the processor of the single device and based on a plurality of resource sharing configurations that specify different sets of network requirements, logical resources, of the set of logical resources, and physical resources, of the set of physical resources, that are to be shared between the plurality of virtual routers.

A routing system, comprising:
- a single device that implements a plurality of virtual routers,
- the single device being implemented at least partially in hardware, and
- the single device including:
- a set of logical resources between the plurality of virtual routers implemented by the single device;
- and
- a set of physical resources between the plurality of virtual routers implemented by the single device,
- a plurality of resource sharing configurations specifying different sets of network requirements that specify logical resources, of the set of logical resources, and physical resources, of the set of physical resources, that are to be shared between the plurality of virtual routers.

A network point-of-presence (POP) device comprising:
- a single physical router including a plurality of resources,
- the single physical router being implemented at least partially in hardware, and the plurality of resources including:
- logical resources, and
- physical resources,
- the single physical router further including:
- at least one backbone router, implemented as a virtual router by the single physical router, at an end-point of a high capacity network link, and
- at least one regional router implemented as a virtual router by the single physical router,
- the at least one backbone router and the at least one regional router sharing resources, of the single physical router, based on a plurality of resource sharing configurations that reconfigurably specifies different sets of network requirements that specify logical resources and physical resources that are to be shared between the backbone router and the regional router.
