摘要： In one embodiment, a method includes obtaining an indication that a state associated with a node is to be changed and preventing data from being received on a first link. The method also includes updating at least one selected from a group including an incoming interface check (IIC) table and an outgoing interface (OIF) table to reflect the state. The state indicates that a second link is to be activated. Finally, the method includes allowing the data to be received on the second link after updating either or both the IIC table and the OIF table and after the timer duration for the NULL value for IIC has expired.

摘要： An example method includes disengaging a target node from a cluster, where the disengaging comprises: selecting an inheritor; migrating flows from the target node to the inheritor; informing a migration manager that the target node is disengaged from the cluster; and broadcasting to peer nodes of the target node that the target node is replaced by the inheritor. In particular implementations of the present disclosure, the cluster can include a first layer of a network topology including a forwarding engine that implements hash-based packet forwarding; a second layer of the network topology comprising the target node and the inheritor, where the target node and the inheritor implement flow-based packet forwarding; and a third layer including service nodes configured for packet processing in a network.

摘要： In one embodiment, a first switch at a border between a first network of a first protocol (P1 network) and a first network of a second protocol (P2 network) is interconnected via the first P1 network with a second switch between a second P1 network (interconnected with the first P1 network) and a second P2 network. In response to detecting a merge of the first and second P2 networks, the first switch may: i) block data packets from traversing P1 network boundary ports of the first switch; ii) allow protocol messages to flow between the first and second P1 networks through the P1 network boundary ports of the first switch; iii) allow the first and second P1 networks to discover each other through the protocol messages and to prevent loops; and in response, iv) unblock the P1 network boundary ports of the first switch to allow traversal of data packets.

摘要： Systems, methods, and other embodiments associated with computing path costs based on link cost as a primary metric and hop cost as a secondary metric are presented. The secondary metric facilitates distinguishing between what would be equal cost multi-paths if only link cost was employed. One example method includes computing a modified link cost for a plurality of paths between switches. The example method may also include determining a lowest modified link cost associated with a path between the switches. The example method may also include providing a signal identifying the lowest modified link cost.

摘要： A system and method for load balancing transmissions across a multilink frame relay connection is disclosed. A credit value is assigned to each bundle link in the multilink based on the amount of data transmitted over a set period of time. Frames or frame fragments are sent over the link with the highest credit value. Credit is subtracted from the link in proportion to the size of the frame or frame fragment. When two or more links have the same credit value, the frame or fragment is sent over the slowest link. The credit values are reset when a specified time period has passed, a link has a negative credit value, or all the links have a credit value of zero.

摘要： A system and method runs a multiple spanning tree protocol (MSTP) in a computer network having a very large number of bridge domains. The computer network includes a plurality of intermediate network devices, each having a plurality of ports for forwarding network messages. Within each device, a plurality of bridge domains are defined, each bridge domain is identified by a Virtual Local Area Network (VLAN) Identifier (VID), and one or more device ports. For each port, a separate mapping of VIDs to Multiple Spanning Tree Instances (MSTIs), based on the bridge domains defined at the port, is established. Each mapping is converted to a port-based configuration digest, which is entered into Spanning Tree Protocol (STP) control messages sent from the respective port. Ports receiving STP control messages whose configuration digest values that match the configuration digests values computed for the ports are said to be in the same Multiple Spanning Tree region. Ports whose configuration digests differ from the configuration digests of received STP control messages are said to be in different regions.

摘要： In one embodiment, a first switch is located at a first border between first networks that utilize a STP to detect and break loops and second networks. The first switch is interconnected via the first networks with a second switch located at a second border between the first networks and the second networks. The first switch detects, via a protocol other than STP, addition of a link in the second networks that provides a new path across the second networks between the first switch and the second switch. The first switch blocks data packets from traversing through one or more network boundary ports of the first switch coupled to the first networks, while allowing STP BPDUs to traverse through the one or more network boundary ports, for a period of time sufficient for the first networks to discover the new path using STP.
摘要翻译：在一个实施例中，第一交换机位于利用STP检测和中断环路和第二网络的第一网络之间的第一边界。第一交换机经由第一网络与位于第一网络和第二网络之间的第二边界处的第二交换机相互连接。第一交换机通过除了STP之外的协议来检测在第二网络中添加链路，以在第一交换机和第二交换机之间跨越第二网络提供新的路径。第一交换机阻止数据分组穿过耦合到第一网络的第一交换机的一个或多个网络边界端口，同时允许STP BPDU跨越一个或多个网络边界端口遍历足够于第一网络的时间段发现使用STP的新路径。
