摘要： A novel and useful system and method for fast protection of dual homed Virtual Private LAN Service (VPLS) spokes. Fast protection is achieved by forwarding traffic to the dual homed VPLS spoke from the VSI that is not currently the one currently serving it, as long as the traffic is known unicast. Egress traffic at the VSI that does not currently serve the VPLS-spoke is re-routed over a protection transport entity to the VPLS-spoke through the device of the VSI currently serving it. Broadcast, multicast and unknown (BMU) traffic is sent to the VPLS spoke only by the BMU-primary VSI. BMU frames received at the BMU-secondary VSI are dropped. A fast election process serves to elect the BMU-primary for coordinating between the two VSIs serving the same VPLS spoke. In addition, a flag is inserted in each frame at an ingress VSI to indicate whether the frame is known or unknown unicast. Unknown unicast frames are forwarded to the VPLS spoke only by the BMU-primary.
摘要翻译：一种新颖有用的系统和方法，用于双重归属虚拟专用局域网服务（VPLS）辐射的快速保护。只要业务被称为单播，就可以通过将流量从VSI转发到目前不在服务的VSI的双归属VPLS分支来实现快速保护。目前不服务于VPLS-spoke的VSI上的出口流量通过保护传输实体通过目前服务于其的VSI的设备重新路由到VPLS-spoke。广播，组播和未知（BMU）流量仅通过BMU主VSI发送到VPLS。在BMU次级VSI处接收到的BMU帧被丢弃。快速选举过程用于选择BMU主用于在服务于相同VPLS语音的两个VSI之间进行协调。另外，在入口VSI的每个帧中插入一个标志，以指示该帧是否是已知的或未知的单播。未知的单播帧被转发到仅由BMU主设备的VPLS辐条。

摘要： A fast protection mechanism capable of maintaining end-to-end and fast local protection on the order of sub 50 ms for both VLAN only based connections and for connections that are based partially on VLAN technology and partially on MPLS technology. The present invention is suitable for use edge switches configured in a stack or ring topology. The NMS provisions both the main and alternative VLANs in each edge switch in the stack portions of the network. When a link failure occurs, the edge switches on either end of the failed link immediately switch all protected traffic going through that link to the alternative VLAN. The packets are then returned on the links over which they were received. Hello messages are used to signal the remote end that a link failure has occurred and that protected traffic must be switched to the main or alternative VLAN in accordance with the VLAN the Hello message was received on.

摘要： A novel and useful one-to-many OAM/protection inter-work function (IWF). The mechanism stitches a single OAM session (e.g., a CCM session) on a multi-traffic class (TC) M-domain to multiple OAM-sessions (which monitor different transport entities or connections) on a single-TC S-domain using duplication and filtering of OAM messages at the ENNI. Using the OAM sessions, protection decision manipulation is performed to coordinate the protection decisions of the different connections serving the different TCs of the same S-domain endpoint. The manipulation includes manipulating fields in one OAM-session as a function of information gained from an OAM-session monitoring a different transport entity such that the first connection is forced to follow protection decisions based on the second OAM-session. Bundled single-TC connections are forced to take protection decisions that steer user traffic through transport entities provisioned in advance to share the same fate in the event of link or equipment failures.

摘要： A novel mechanism for performing policy aware frame loss measurements that overcomes the problems of the prior art. The mechanism permits OAM frames to travel through the network in the same way data frames travel marked as green or yellow. The frame loss measurement is policy aware (i.e. SLA aware), taking CIR and EIR policy as well as policy in the middle of the network into consideration. In one embodiment, the value of the policer at the ingress to the client side is read just before sending an OAM frame and a potential decision value is calculated which reflects the decision that the policer would have taken if given the OAM frame at that time. If the calculated decision is to send the OAM frame as green or yellow, the frame is sent as green or yellow, accordingly. If, however, the calculated decision to drop the frame, the frame is randomly marked as either green or yellow in accordance with the ratio of CIR to EIR. In another embodiment, red traffic (i.e. dropped frames) is simulated using CIR and EIR counters. In another embodiment, frame loss measurements are made that take into account the action taken by policers in the middle of the network.
摘要翻译：用于执行克服现有技术问题的策略感知帧丢失测量的新颖机制。该机制允许OAM帧以与数据帧旅行标记为绿色或黄色相同的方式通过网络。帧丢失测量是政策意识（即SLA感知），考虑CIR和EIR策略以及网络中间的策略。在一个实施例中，在发送OAM帧之前读取在客户端入口处的策略器的值，并且计算潜在的决定值，其反映了当在该时间给定OAM帧时策略器将采取的决定。如果计算出的决定是将OAM帧发送为绿色或黄色，则相应地发送帧为绿色或黄色。然而，如果计算出的丢弃帧的决定，则根据CIR与EIR的比率将帧随机标记为绿色或黄色。在另一个实施例中，使用CIR和EIR计数器来模拟红色业务（即丢弃的帧）。在另一个实施例中，进行考虑了在网络中间的策略器采取的动作的帧丢失测量。

摘要： An end-to-end monitoring mechanism whereby edge nodes are notified that a particular path flows through a local protection tunnel along the way. The notification mechanism utilizes OAM packets which include a link protection indication that are transmitted on the Ethernet service layer. The link protection indication may be represented by one or more flags to indicate that local protection is in place along the path. The mechanism enables fast local protection to be used with slower end-to-end protection by informing the latter when local protection is activated. In an implementation in which local-protection does not preserve the CIR of the protected traffic, the invention provides minimal interruption of Committed Information Rate (CIR) connections by minimizing the time traffic is diverted through local protection tunnels. Notification of the edge node that local protection is in use occurs very quickly, thus allowing the edge node to rapidly switch to a backup path.
摘要翻译：端到端监控机制，通过边缘节点通知特定路径沿着本地保护隧道流过。通知机制利用OAM包，包括在以太网业务层上发送的链路保护指示。链路保护指示可以由一个或多个标志来表示，以指示沿着该路径的本地保护就位。该机制使得能够通过在启用本地保护时通知后者来实现较慢的端到端保护，从而实现快速本地保护。在本地保护不保护受保护流量的CIR的实现中，本发明通过最小化通过本地保护隧道转发的时间来最小化承诺信息速率（CIR）连接的中断。本地保护正在使用的边缘节点的通知非常快，从而允许边缘节点快速切换到备份路径。

摘要： A link based network protection path calculation mechanism wherein a protection route is calculated that is guaranteed not to traverse the link it is intended to protect. The mechanism takes advantage of the fact that the same color cannot pass twice through the same optical fiber. The protection path is determined by eliminating all colors from the logical topology of the network except for the color corresponding to the link to be protected before executing the search algorithm. This serves to guarantee that the protection path calculated will not traverse the same physical fiber as the link to be protected. Virtual colors can be assigned to the links running through fiber bundles such that they do not pass through the same fiber/bundle twice.

摘要： A novel and useful hitless node insertion mechanism for configuring a new node to be inserted into an Ethernet network. The mechanism comprises pre-configuring the new node into a partially configured state, disconnecting a network link where the new node is to be inserted and connecting the new node to at least one end of the disconnected link. All data traffic received from neighboring nodes is then blocked and fake signal failure (SF) messages are generated and sent if Ethernet Ring Protection (ERP) messages are detected. An in-band management port is then selected and a configuration from a Network Management System (NMS) is received. Once configuration of the said new node is complete, the new node is set to a fully configured state.
