A method and a device for determining a Segment Identity by receiving a first message and a second message sent by a second device; the first message including at least one first Block Identity and a boundary address of an address space corresponding to each first Block Identity; the second message including at least a second Block Identity and a first index value; calculating the first SID by using a boundary address of a first address space corresponding to a same Block and the first index value, wherein the same Block is a Block characterized by the same Block Identity in at least one first Block Identity and at least one second Block Identity. The overhead of messages in the process of issuing SIDs is reduced, thus ensuring the performance of devices and the stability of message transmission protocol.

Method and apparatus for determining segment identity

Method and apparatus for generating a forwarding path, network device and storage medium. Method comprises: obtaining topology information of first network nodes supporting a target path calculation algorithm; performing, using the target path calculation algorithm, path calculation based on the topology information of first network nodes to generate a first forwarding path; obtaining a second forwarding path from the source node to the tail node when there is a path interruption in the first forwarding path; determining, from the second forwarding path, first network nodes communicated with second network nodes obtaining node pairs; updating a next hop device of the first node in each node pair on the second forwarding path as the second node in the node pair obtaining a forwarding path communicated from the source node to the tail node. Second node is located behind first node in each node pair in a direction of second forwarding path.

Method and apparatus generating a forwarding path, network device and storage medium

The present application provides a method and apparatus for synchronizing information between switches. The method includes: acquiring to-be-synchronized target data; sending BGP routes carrying the target data through BGP sessions established between the switch with one or more designated switches, so that the target data is synchronized between the switch and target switches that need to synchronize with the switch.
