Abstract
Methods and systems for offering network-based managed security services are provided. According to one embodiment, an IP service processing switch includes multiple service blades and one or more packet-passing data rings. The service blades each have multiple processors for providing customized security services to subscribers of a service provider. Upon receipt of a packet by a service blade from the one or more packet-passing data rings, a PEID value within the packet is inspected and when the PEID value corresponds to a PEID assigned to a processor associated with the service blade, the packet is steered to a software entity of a VR on the processor that corresponds to an LQID value within the packet. And, when the PEID value does not correspond to any PEIDs assigned to processors on the service blade, the packet is passed to a next service blade on the one or more packet-passing data rings.
