Abstract:
1. A method comprising: providing a first service processing switch at a first point-of-presence (POP) associated with a first site of a first subscriber of a service provider and a first site of a second subscriber of the service provider; providing a second service processing switch at a second POP associated with a second site of the first subscriber and a second site of the second subscriber, wherein the first service processing switch and the second service processing switch are communicatively coupled via a network; logically connecting a plurality of processors of the first service processing switch into a packet-passing ring configuration; logically connecting a plurality of processors of the second service processing switch into a packet-passing ring configuration; establishing a first set of virtual routers on the plurality of processors of the first service processing switch; establishing a second set of virtual routers on the plurality of processors of the second service processing switch; providing the first subscriber with a first set of customized application layer services and the second subscriber with a second set of customized application layer services and providing subscriber resource isolation by providing changeable provisioning of processing capacity between the first subscriber and the second subscriber by programmatically dynamically reallocating resources of the first service processing switch or the second service processing switch between the first partition and the second partition based on comparative processing demands of the first set of customized application layer services and the second set of customized application layer services.
