The embodiment of the invention provides a disaster recovery method and disaster recovery equipment. The disaster recovery method comprises the following steps: first network equipment is used for monitoring faults of second network equipment; the first network equipment is used for finding a standby PW set corresponding to a primary virtual link PW set from the pre-configured information; the first network equipment switches a state of a second primary PW in the standby PW set to active-active from inactive-active, and switches the state of the second standby PW to active-inactive from inactive-inactive; the first network equipment utilizes the standby PW set to send the received business data to network transfer equipment connected with the third network equipment; when the second network equipment has faults, the first network equipment utilizes the standby PW set to send the received business data to the third network equipment which is taken as standby equipment of the second network equipment, thereby realizing business data normal transmission charged by the second network equipment.

The invention discloses a data synchronization method and device; the method comprises the following steps: synchronizing history data of a main device to a standby device before data synchronization; determining whether the main device has data change or not in a running process when the main device and the standby device perform history data synchronization; if yes, synchronizing the changed data to the standby device. In the prior art, when a host and a spare machine are not simultaneously powered up, the host needs to be shut down when the host and spare machine need data synchronization; the novel data synchronization method and device can solve the said problems, so the host system needs not be shut down in data synchronization, thus improving system stability.

An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and comprising a compression module that is operable to receive a plurality of bits associated with a communications flow, to inspect the bits, to determine whether one or more samples included in the flow should be suppressed, and to compress the samples. The cell site element is coupled to a back-up device that is operable to assume responsibility for active flows in a case where a primary device fails. Data is exchanged between the primary device and the back-up device, the data guiding the back-up device in how to process the active flows.

The invention discloses a data backup method. The method comprises the following steps of obtaining device state information of a target GPU device currently used for model training; judging whether the GPU equipment meets an early warning condition or not according to the equipment state information; if yes, performing storage operation on the model training data; and when it is detected that thedriving of the target GPU equipment fails, sending the model training data to standby GPU equipment of the target GPU equipment in the GPU cluster. By applying the technical scheme provided by the embodiment of the invention, the time is greatly saved, and the training efficiency is improved. The invention further discloses a data backup device and equipment and a storage medium, which have corresponding technical effects.

The invention discloses a traffic load sharing realization method based on a VRRPE backup group and a realization apparatus thereof. The method comprises the following steps sending a media access control (MAC) address allocation request to members in the backup group when a route device is added into the backup group; when master equipment receives the request, allocating a virtual MAC address, sending the virtual MAC address to member equipment in the group, carrying out load balancing calculation based on an address resolution protocol (ARP) entry so as to obtain a virtual MAC address of a target route device of a client in the entry, and sending the virtual MAC address of the target route device to the client for gateway MAC address update; when backup equipment in the group receive the virtual MAC address allocated by the master equipment for the newly-added route device, carrying out load balancing calculation based on an ARP entry so as to obtain a virtual MAC address of a target route device of a client in the entry, and sending the virtual MAC address of the target route device to the client for gateway MAC address update. According to the invention, when the state of the VRRPE backup group changes, traffic load sharing can be realized in time.

The invention relates to the field of satellite communication, discloses a distributed fault real-time monitoring and standby equipment switching method for satellite communication, and solves the problem of interruption of a satellite communication network caused by faults of node equipment in a large-scale satellite communication system. According to the technical scheme, the method is characterized by comprising the following steps that S1, a special management and control server is set for a satellite communication system to operate a management and control service system; S2, the management and control service system receives a fault alarm frame in the satellite network in real time through a narrowband control channel; S3, the management and control service system automatically completes state notification of the whole network equipment and the whole network service system; S4, the management and control service system generates network parameters for standby equipment to accessthe network; S5, the management and control service system automatically responds and sends a control frame switched to the standby equipment to complete troubleshooting according to the fault framesobtained actively and passively. According to the invention, real-time monitoring of equipment states of a central station and a gateway station can be realized, fault monitoring and switching are automatically completed by the management and control service system, the operation reliability of the equipment and the service system of the central station and the gateway station is greatly improved,and the problem of low efficiency of manual monitoring and switching is effectively solved at the same time.

The invention discloses a network switching method and system based on a dual redundant system, and a storage medium. The method comprises the following steps: standby equipment monitors a routing table entry and an ARP table entry of main equipment; when the main equipment adds or deletes the routing table entry and the ARP table entry in the process of establishing communication with the user host, the standby equipment synchronously adds or deletes the same table entry; and after the dual-computer redundant system is switched, the standby equipment has routing table entries and ARP table entries on which the communication with the user host is established, and the standby equipment becomes new main equipment to finish the switching of network communication. According to the method, after the dual redundant system is switched, the original standby equipment has the routing table entry and the ARP table entry which are depended on for establishing communication with the user host without operating the routing protocol and the ARP protocol after being changed into the new main equipment, so that the switching of network communication is quickly completed.
