摘要： Packet switch operating methods and packet switches provision a plurality of tunnels on a packet switch by associating each of the plurality of tunnels with a packet switch port and by configuring the packet switch to modify packets relayed by the tunnel to include a transport identifier associated with the tunnel. The tunnels of the plurality relay packets when permitted by a tunnel index. The plurality of tunnels and the tunnel index are associated with a virtual interface. The methods and packet switches also permit a first tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the first tunnel. The tunnel index indicates only one tunnel. The methods and packet switches also enable a second tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the second tunnel, thereby preventing the first tunnel from relaying packets.

One of the plurality is designated a primary tunnel configured to accept packets. Other tunnels of the plurality are designated as backup tunnels and are configured to reject packets. The methods and packet switches also determine which of the plurality of tunnels is the primary tunnel and determine a packet switch port associated with the primary tunnel. The methods and packet switches egress the packet via the primary tunnel on the packet switch port associated with the primary tunnel.

摘要： Packet switch operating methods and packet switches forward a first packet to a first packet switch via an active primary tunnel terminating on the first packet switch. The primary tunnel is associated with an inactive backup tunnel terminating on a different second packet switch. The methods and packet switches also deactivate the primary tunnel, activate the backup tunnel, and forward a second packet to the second packet switch via the activated backup tunnel. Network operating methods relay a first packet to a first one of a plurality of destination packet switches via two or more different tunnels in a first combination. The methods and packets switches also deactivate one of the tunnels of the first combination without deactivating any other tunnel of the first combination and relay a second packet to a second one of the packet switches via two or more different tunnels in a second combination.

摘要： Packet switch operating methods and packet switches detect, at a packet switch, a change in a first tunnel's ability to relay packets between the packet switch and another packet switch and, in response, send a control packet to the other packet switch. The control packet indicates a particular one of the tunnels is active on the packet switch. The packet switches are coupled together by the first tunnel and a second tunnel. A packet switch network includes a first packet switch and a second packet switch both configured to recognize disagreement regarding which one of a first tunnel and a second tunnel is active and which one is inactive in response to receiving control packets from each other and resolve the disagreement so that a particular one of the first tunnel and the second tunnel is active according to both the first packet switch and the second packet switch.

摘要： Systems and methods with dynamic Connectivity Fault Management (CFM) and Continuity Check Messages (CCMs) that enable dynamic configurations to avoid limitations associated with static reconfigurations. Variously, a network, a method, and a network element are configured to implement a dynamic CFM method for dynamic notifications and actions taken based thereon between Maintenance End Points (MEPs). The systems and methods may also include a CCM attribute adjustment method between two MEPs, a CCM suspension and/or resumption method between two MEPs, and a MEP auto-discovery and leaving method. Advantageously, the systems and methods may be utilized in a variety of contexts including controlled maintenance, in-service software upgrades, network congestion, discovery of new remote MEPs, and the like to enable dynamic configurations between MEPs. The systems and methods may also apply to Carrier Ethernet, Multiprotocol Label Switching-Transport Profile (MPLS-TP), and the like.
