A network gateway element is provided. The network gateway element appears as a single node to the external world, while it physically is maintained in at least two chassis. A routing node handles functions typically associated with routers, while another network element, such as a server, may handle functions typically associated with the server. The routing node may load-balance the traffic directed at the server. Additionally, the routing node may process packets for the server without the server having to become involved.

In one embodiment, a device in a computer network establishes a reliable map that defines a set of packet criteria for which reliability is desired over an unreliable link to a peer device. In response to receiving a first packet from the peer device over the unreliable link, the device acknowledges the first packet to the peer device when the first packet matches the packet criteria of the reliable map. Also, in response to receiving a second packet destined via the peer device over the unreliable link, the device buffers the second packet when the second packet matches the packet criteria of the reliable map and retransmits the buffered second packet over the unreliable link to the peer device until acknowledged by the peer device.

A system and method for implementing an overlay network architecture called a Virtual Collapsed Backbone (VCB) are described herein. In one embodiment, a VCB provides a framework for consolidating campus network service elements in a centralized fashion, instead of distributing them at the edges of the campus network. End stations create tunnels to a new type of network device called Network Junction Point (NJP) located in the campus network and the NJP steers the traffic through service elements selected based on the traffic steering policy. Other methods and apparatuses are also described.

An efficient method and system for maintaining the data connectivity with the MLPPP peer in the event of failure of the processor running the Active MLPPP protocol engine, without requiring expensive, per-packet update messages between the redundant nodes is provided. Grouping of information from multiple bundles is implemented to implement multi-bundle redundancy.
