A method for synchronizing network elements to a global clock derived from the GPS clock acquired by a plurality of base stations. The global clock is distributed to controllers of various networks, and from there to network access devices. The network access devices further distribute the global clock to various wire-line and local wireless networks and from there, to the users served by these networks. The user equipment is enabled with a simple clock discipliner that adjusts the local clock to the global clock, resulting in a reliable synchronization across the converged communication networks.

The ECMS also performs migration of containers between hosts in a network when the host running the container runs out of the resources.

The invention provides a server switching method, device and system and a readable storage medium, and relates to the technical field of articulated naturality web. According to the method, a standbyserver sends an online confirmation message to a main protocol conversion server, the main protocol conversion server is determined to be in an offline state under the condition that a response message returned by the main protocol conversion server is not received, and then the main protocol conversion server is switched to a working state, wherein the main message number of the standby server, the stored data and the configured program are the same as the main message number of the main protocol conversion server, the stored data and the configured program. Thus, the standby server enters the working state when the main protocol conversion server is offline, the standby server can replace the main protocol conversion server to provide service during the offline period of the main protocol conversion server, and the problem of service interruption caused by the fact that the main protocol conversion server enters the offline state due to faults is avoided.

Application servers are programmed such that when an application server changes a compromised service key, the compromised key is saved by the application server until all tickets that may have been issued under the compromised key expire. Whenever the application server receives a ticket from a client issued under the compromised key, it generates an authenticator for an error message using the session key extracted from the ticket and sends the error message with this authenticator to the client. Clients are programmed to be able to receive error messages from application servers that have changed their service keys. Because the error messages include an authenticator generated by the application server using the session key extracted from the compromised ticket, the client is able to rely on the error message. The client is able to automatically request a new ticket from a key distribution center in response to a successful authentication of the error message.
