The invention is directed toward techniques for Multi-Protocol Label Switching (MPLS) upstream label assignment for the Resource Reservation Protocol with Traffic Engineering (RSVP-TE) The techniques include extensions to the RSVP-TE that enable distribution of upstream assigned labels in Path messages from an upstream router to two or more downstream routers of tunnel established over a network The tunnel may comprise a RSVP-TE P2MP Label Switched Path (LSP) or an Internet Protocol (IP) multicast tunnel The techniques also include extensions to the RSVP-TE that enable a router to advertise upstream label assignment capability to neighboring routers in the network The MPLS upstream label assignment using RSVP-TE described herein enables a branch router to avoid traffic replication on a Local Area Network (LAN) for RSVP-TE P2MP LSPs

Resource reservation protocol with traffic engineering point to multi-point label switched path hierarchy

Some embodiments provide a method that processes network data through a network. The method receives a packet destined for a network host associated with a logical datapath set implemented by a set of managed edge switching elements and a set of managed non-edge switching elements in the network. The method determines whether the packet is a known packet. When the packet is a known packet, the method forwards the packet to a managed switching element in the set of managed edge switching elements for forwarding to the network host. When the packet is not a known packet, the method forwards the packet to a managed switching element in the set of managed non-edge switching elements for further processing.

Packet processing for logical datapath sets

Principles of the invention relate to techniques for transmission of Layer 2 (L2) traffic over a point to multi-point (P2MP) label switched path (LSP) within a multi-protocol Label Switching (MPLS) network. A source or ingress network device may implement the techniques to connect multiple L2 interfaces to a P2MP LSP within an MPLS network via a P2MP Pseudo-Wire (PW) mechanism that emulates delivery of L2 data units over a packet switched network, such as the MPLS network. The ingress network device first establishes the P2MP LSP and then connects two or more L2 interfaces to the P2MP LSP via the P2MP PW mechanism. Egress network devices may also implement the techniques to terminate the P2MP LSP and de-multiplex traffic arriving via multiple P2MP PWs carried over the same P2MP LSP.

Transmission of layer two (l2) multicast traffic over multi-protocol label switching networks

The label distribution protocol (LDP) is extended to set up a point to multi-point (P2MP) label switched path (LSP) across a computer network from a source network device to one or more destination network devices. LDP is extended to create a P2MP label map message containing a label and a P2MP forwarding equivalence class (FEC) element having a root node address and an identifier. The P2MP FEC element may, for example, associate an address of the root node of the P2MP LSP with an opaque identifier. The P2MP FEC element uniquely identifies the P2MP LSP. The P2MP FEC element may be advertised with a label in a P2MP label map message. A source network device or the destination network devices may initiate setup and teardown of the P2MP LSP. The P2MP label map messages may be propagated from the destination network devices to the source network device.

A provider edge device, associated with a virtual private local area network service (VPLS) system, includes a memory to store instructions to implement a pseudowire mechanism to receive a first data frame from a source customer edge (CE) device associated with the VPLS system, incorporate the first data frame into a first VPLS packet, determine whether the source CE device is a single-homed CE device or a multi-homed CE device, and incorporate, into the first VPLS packet, a first pseudowire label, if the source CE device is a single-homed CE device, and incorporate, into the first VPLS packet, a second pseudowire label, different from the first pseudowire label, if the source CE device is a multi-homed CE device; and a processor to execute the instructions.

A method of processing traffic in a Virtual Private LAN service includes replacing a MAC address from a packet with a realm specific Virtual Private Network address. The packet with the realm specific Virtual Private Network address is then processed.
