    摘要: A technique is provided for mitigating loops in Ethernet networks. A first port in an Ethernet device receives an Ethernet frame. The frame includes a source identifier, a destination identifier, and a Virtual Local Area Network Identifier (VLAN ID). According to various embodiments, the VLAN ID (VID) has the encoding of both a community group as well as a source bridge ID. A VID database is accessed using the destination identifier and the VID to determine whether the first port has ingress enabled. A filtering database is accessed to determine an egress port for forwarding the Ethernet frame.

    摘要: A broadband access node includes a port for connection with a Digital Subscriber Line and a processor to run code that implements a virtual maintenance end point (vMEP). The vMEP translates an IEEE 802.1ag Loopback Message (LBM) received from a device on an Ethernet access network into a legacy operations and maintenance (OAM) message that is transmitted to a residential gateway (RG) device. The legacy OAM message determines a link-level connectivity status between broadband access node and the RG device. The vMEP also transmits a reply message back to the device on an Ethernet access network in compliance with the IEEE 802.1ag specification. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

    摘要: The present invention provides improved unicast routing, multicast routing and unicast load sharing as compared with conventional methods. Preferred implementations of the invention provide improvements to IEEE 802.1Q. According to preferred aspects of the invention, each bridge is the root of its own multiple spanning tree instance (“MSTI”). Preferred implementations of the invention require no learning of media access control (“MAC”) addresses on the backbone of a network. Some methods of the invention can resolve spanning tree asymmetries. Preferred implementations of the invention require a very low computational load for control protocols.

    摘要: An encapsulation mechanism efficiently transports packets between ports of different switches in a network on the basis of, inter alia, virtual local area network (VLAN) associations among those ports. The switches are preferably interconnected by a novel interswitch link (ISL) mechanism that appends ISL destination and source information, along with ISL error detection information, to VLAN-modified packets. The ISL mechanism keeps the VLAN associations of the packets intact during transfer between the switches in accordance with a high-performance switching bus architecture.

    摘要: In particular embodiments, a first switch implementing a first virtual local area network (VLAN) registration protocol and connected to a first end of the trunk detects whether a second switch connected to a second end of the trunk implements the first VLAN registration protocol. In an embodiment, the second switch may send an unsolicited message to the first switch indicating the VLAN registration protocol implemented by the second switch. The first switch may then determine the VLAN registration protocol implemented by the second switch. Alternatively, the first switch may send a solicited message to the second switch. By receiving a response to the solicited message, the first switch can determine that the second switch implements the first VLAN registration protocol. In response to determining that the second switch implements the first VLAN registration protocol, the first switch may enable a pruning technique in accordance with the first VLAN registration protocol.
