摘要： Methods and apparatus are provided for managing multicast Internet Protocol (IP) flows. According to one embodiment, a multicast IP flow is identified at an interface of a network device using information from a packet header. For any newly identified multicast IP flow, if flow-specific services are required, a new first transmit control block (TCB), which includes one or more attributes relating to flow-specific services required by the newly identified multicast IP flow, is created for the newly identified multicast IP flow. Otherwise, if flow-specific services are not required by the newly identified multicast IP flow, a default second TCB, which excludes any attributes relating to flow-specific services and which includes one or more attributes related to a virtual interface (VI) serving as an outbound interface (OIF) for the newly identified multicast IP flow, is used.

摘要： Methods, apparatus and data structures are provided for managing multicast IP flows. According to one embodiment, a memory of a router has stored therein a data structure, which includes information relating to multicast sessions being handled by the router and including a first pointer for each multicast session, at least one chain of blocks of second pointers and one or more TCBs. Each first pointer points to a chain of blocks of second pointers. Each second pointer corresponds to an OIF of the router participating in the multicast session defined by the first pointer and defines how many times packets associated with the multicast session are to be replicated. The TCBs are configured to store control information relevant to processing or routing packets. Each second pointer points to a TCB and each TCB identifies the OIF out which packets of the multicast session are transmitted from the router.

摘要： Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a method for routing packets in a router includes establishing a flow data structure, which identifies a packet flow through a virtual router in the router. When a packet is received, a comparison is performed between a subset of at least one packet header associated with the packet and a subset of the flow data structure. If the subset of the packet header matches the subset of the flow data structure, then the packet can be hardware accelerated to a network interface. Otherwise, the packet may be either dropped or forwarded to a general purpose processor for processing.

摘要： This document describes, among other things, a router providing service-enabled multicast forwarding for a flow-based architecture. Services are enabled using inbound/outbound policies from Access Control Lists (ACLs). In a first mode, per-flow services are not enabled, and flows are aggregated for efficiency. In a second mode, per-flow services are enabled, and control information for an outbound interface (OIF) is shared across all multicast flows that do not have per-flow service enabled. A flow management scheme for these modes allows dynamic multicast membership updates while reducing disruption of active flows. This supports a large multicast OIF list and a high rate of multicast “Joins” and “Leaves”. This provides scalability and performance, such as desired for deploying multicast for broadband subscriber applications.

摘要： 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.
