Abstract: The examples of the present disclosure provide a method and a device for determining a Segment Identity, and relates to the field of communication. The solution is as follows: receiving a first message and a second message sent by a second device; the first message includes at least one first Block Identity and a boundary address of an address space corresponding to each first Block Identity; the second message includes 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, where 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. By applying the technical solution provided by the examples of the present disclosure, 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.

Abstract: The present disclosure provides message sending, which relates to the technical field of communication. The technical solution provided by the present disclosure includes: receiving a first message; sending a second message, wherein the second message includes a segment routing header SRH and the first message, and wherein the SRH includes a plurality of compressed segment identifier C-SID containers and segment description information, and the segment description information includes a Block length, a C-SID length and a compression type of C-SID carried by each C-SID container, so that a complete segment list can be restored offline.

Abstract: 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.
