A forwarding component of a routing node floods copies of a packet to a plurality of next hops associated with the same layer two (L2) network as an interface on which the packet was received. The plurality of next hops excludes a next hop that corresponds to the interface that received the packet. The forwarding component requires that forwarding information installed by a control unit specify the plurality of next hops to which to flood the copies of the packet, and the forwarding component is not capable of deriving the plurality of next hops to which to flood the copies of the packet from a single flooding next hop identifier after the packet is received. Prior to receiving the packet, a flooding next hop control module derives the plurality of next hops based on the flooding next hop and installs the derived next hops into the forwarding information.

Samples from an addressed data forwarding devices, such as a router, are forwarded to a specified next hop address and/or out a specified next hop interface. However, the sampling and/or next hop forwarding is suppressed if the specified next hop address is unstable or unresolved.

Samples from an addressed data forwarding devices, such as a router, are associated with path-centric information. Information from the samples is used to update corresponding path-centric traffic information, such as flow information for example. The aggregated path-centric traffic information can then be used by traffic analysis operations.

A method and system generate a boundary of a Schmoo plot. In accord with the method, a plurality of seed points having a resolution that is less than or equal to the acquisition resolution indicated by a smoothness of a representative Schmoo boundary are selected. A coarse boundary search is performed to identify a plurality of test points that are within an acquisition resolution of the boundary. The test points that comprise the coarse boundary are interpolated to produce a fine estimate of the boundary.

In general, techniques are described for flooding VPLS traffic with a network device according to flood groups. The network device resides within a layer 3 (L3) network and includes a control unit that executes a virtual private LAN service (VPLS) protocol that enables a VPLS domain to operate over the L3 network. The network device further includes a plurality of packet forwarding engines, each of which include a plurality of interface cards that receive a layer 2 (L2) message originating from the L2 network. The packet forwarding engines associate the L2 packet with a configurable flood group, wherein the flood group defines criteria to determine which messages to associate to the flood group and indicates a set of the interface cards for forwarding the associated messages. The packet forwarding engines further flood the L2 packet via each interface card indicated by the associated flood group.

A network device includes a memory, a routing engine and a forwarding engine. The memory stores a forwarding table and the routing engine constructs a first composite next hop that includes multiple next hops, where each of the multiple next hops represents an action to be taken on a data unit as it transits the network device or represents another composite next hop, and where the first composite next hop specifies a function to be performed on the plurality of next hops. The routing engine further stores the composite next hop in an entry of the forwarding table. The forwarding engine retrieves the composite next hop from the forwarding table, and forwards a data unit towards one or more network destinations based on the composite next hop.

In general, techniques are described that facilitate application of service within MPLS networks. More specifically, a router comprises a forwarding plane, a service plane and a routing engine. The routing engine maintains data defining an association between a handle identifying a property common to a plurality of packets of a particular context and one or more MPLS labels associated with these packets. The routing engine automatically generates and installs a filter to identify these packets within both the forwarding and service planes. The forwarding plane applies the filter to incoming packets to determine whether each of the incoming packets includes a label matching any of the labels of the filter and forwards the incoming packets to the service plane upon a match. The service card selects one or more services identified by the filter and applies the selected one or more services to the incoming packet.

A network device includes a processor that executes a software module above an operating system of a network device, wherein the software module is configured to create a set of forwarding structures for use in forwarding network traffic with the network device without regard to limitations of an underlying architecture of the forwarding plane. The network device also includes a forwarding structure control module operative within or below the operating system of the network device, wherein the forwarding structure control module is configured to create a set of derived forwarding structures based on the set of forwarding structures provided by the software module for installation in the forwarding information of the forwarding plane. The derived set of forwarding structures is created in accordance with the limitations of the underlying architecture of the forwarding plane.
