A system and method for providing IP services. A packet is received at a line interface/network module and forwarded to a virtual routing engine The virtual routing engine determines if the packet requires processing by a virtual services engine. If the packet requires processing by the virtual services engine, the packet is routed to the virtual services engine for processing.

A virtual routing platform includes a line interface a plurality of virtual routing engines (VREs) to identify packets of different packet flows and perform a hierarchy of metering including at least first and second levels of metering on the packet flows. A first level of metering may be performed on packets of a first packet flow using a first metering control block (MCB). The first level of metering may be one level of metering in a hierarchy of metering levels. A second level of metering on the packets of the first packet flow and packets of a second flow using a second MCB. The second level of metering may be another level of metering in the hierarchy. A cache-lock may be placed on the appropriate MCB prior to performing the level of metering. The first and second MCBs may be data structures stored in a shared memory of the virtual routing platform. The cache-lock may be released after performing the level of metering using the MCB. The cache-lock may comprise setting a lock-bit of a cache line index in a cache tag store, which may identify a MCB in the cache memory. The virtual routing platform may be a multiprocessor system utilizing a shared memory having a first and second processors to perform levels of metering in parallel. In one embodiment, a virtual routing engine may be shared by a plurality of virtual router contexts running in a memory system of a CPU of the virtual routing engine. In this embodiment, the first packet flow may be associated with one virtual router context and the second packet flow is associated with a second virtual router context. The first and second routing contexts may be of a plurality of virtual router contexts resident in the virtual routing engine.

System and method for hierarchical metering in a virtual router based network switch

A method for routing packets in a router includes establishing a flow data structure identifying a packet flow through a virtual router in the router. Next, a system executing the method receives a packet, said packet having at least one packet header. The method then compares a subset of the at least one packet header to a subset of the flow data structure. If the subset of the at least one packet header matches the subset of the flow data structure, then the packet can be hardware accelerated to a network interface. Otherwise, the packet can be either dropped, or forwarded to a general purpose processor for processing.

System and method for routing traffic through a virtual router-based network switch

A network system for managing remote agents of a communication center includes a primary server connected to the network the primary server controlling at least one routing point; one or more secondary servers distributed on the network and accessible to the remote agents, the secondary server or servers having data access to agent computing platforms and communication peripherals; and, a software suite distributed in part to the secondary server or servers and distributed in part to one or more agents computing platforms and peripherals, the software suite including protocol for reporting agent status data. The system monitors agents computing platforms and peripherals for activity state through the one or more secondary servers whereupon the one or more secondary servers exchange control messaging and event related data using ISCC protocols with the primary server over the network for intelligent routing purposes.

In a network routing system, a control blade provides for redundancy and failover of virtual routers (VRs) instantiated by objects running on processing engines of the several virtual routing engines (VREs). When the control blade detects a failure of one processing engines, it may identify the virtual private networks (VPNs) and/or VRs operating on the failed processing engine. The control blade identifies a set of command lines corresponding with the identified VPNs and VRs, and replays the set of command lines with an identity of a new processing engine to recreate the identified VPNs and VRs on the new processing engine.

A method of maintaining a hierarchy of application objects commences with the automatic detection of the exit of a process of a child application object in an unexpected manner. Responsive to the detected exit, a grandchild application object, launched by the child application object, is automatically terminated. An attempt is then made to restart the child application object. The outcome of the restart of the child application object is reported to a parent application object that launched the child application object.

Method and system to maintain a hierarchy of instantiated application objects and to enable recovery from an applications failure

A method maintains a hierarchy of application objects in a computer system. The method includes automatically detecting an exit of a child application object, the exit resulting from a failed process, the child application object launched by a parent application object. A grandchild application object is automatically terminated after the exit of the child application object, the grandchild application object launched by the child application object. Notwithstanding the exit of the child application object, the computer system, which maintains the hierarchy of application objects, the parent application object, and the grandchild application object, remains active.
