Abstract: Disclosed in the present invention are TRIP steel and a preparation method therefor, a cold-rolled steel sheet, and a hot-dip galvanized steel sheet, wherein the TRIP steel comprises the following chemical components, in percentages by mass: C: 0.15-0.3%, Si: 0.6-1.0%, Mn: 1.7-2.5%, Al: 0.5-0.9%, P?0.01%, S?0.01%, N?0.007%, and Fe?90%. The TRIP steel of the present invention is based on carbon-silicon-manganese steel. By means of optimizing the proportions of carbon, silicon, manganese and aluminum, and replacing Si in traditional TRIP steel with a part of the Al, the effects of inhibiting carbide precipitation and stabilizing residual austenite can be achieved so as to ensure the mechanical properties of the TRIP steel, and the surface quality and plateability of the steel sheet can also be improved.

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.

Abstract: A method and apparatus for generating a forwarding path, a network device and a storage medium, related to the technical field of network communications, are provided.

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.
