The information synchronization method, apparatus, electronic device and computer readable storage medium provided in the present application are described in detail below with reference to embodiments.
Fig. 1 is a schematic flow chart of information synchronization according to an embodiment of the present application. Referring to fig. 1, an embodiment of the present application provides an information synchronization method, which may include:
it should be noted that, the information synchronization method provided in the embodiments of the present application may be applied to a power routing control plane, where the power routing control plane may be deployed on a computer device such as a server, a computer, and a network forwarding device such as a router, a switch, and the like.
It should be noted that, in the present application, the power routing control plane is responsible for controlling (issuing, modifying, updating, deleting) the power routing policy information on the power gateway.
And the computing force gateway forwards the service message to the designated computing force node according to the forwarding path designated in the policy information according to the computing force routing policy information.
It should be further noted that, the preconditions for implementing the information synchronization method of the present application are: the power computing nodes are addressed through an anycast-based power computing routing protocol, all power computing nodes providing the same power computing service share the same IP address, and the path and node selection decision is determined by a power computing routing control plane.

The service in the present application may be classified into a stateful service and a stateless service.
Stateless services refer to services without special states, and each request is uniformly and indiscriminately processed for a server, and the request carries all parameters required by all the servers (the server does not store any data related to the request and does not include database storage information).
The stateful business retains the information requested before the server for processing the current request, such as session.

It will be appreciated that in normal circumstances, different identification information should be used for user equipment, cell, stateful services.
The situation that the computing force node is switched in the application can comprise the following two situations:
1. switching the power calculation node due to the change of the access position of the user equipment;

The service context synchronization request is used for indicating the current accessed computing power node of the user equipment and synchronizing the service context information of the user equipment to the computing power node of the adjacent area.
After receiving the service context synchronization request, the service control system instructs the current power computing node accessed by the user equipment to synchronize the service context information of the user equipment in the stateful service to the power computing node in the neighboring cell.
When different user equipment accesses different stateful services, the corresponding service context information is different, so that the specific content of the service context information is not limited.
