Problems solved by technology

During the period from the migration of a service process to the end of the migration of the service process (that is, the service process is re-established on the standby node), the data packet cannot be received normally, but the client will not realize it The data packets sent were not received normally, so the data packets sent by the client during this period will be lost

Abstract

The invention provides a method of data communication and a device of data communication based on the socket. The method includes searching a host socket of a data package after the data package sent by a client is received, searching a tail end data package of a receive queue of the host socket, judging a checking point zone bit of the tail end data package is set as a value which shows that the content of the receive queue is saved in a check point file by a check point process or not. If the checking point zone bit of the tail end data package is set as the value which shows that the content of the receive queue is saved in the check point file by the check point process, and then the received data package is discarded directly.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a data communication method and device. Background technique [0002] With the rapid development of current network technology, many traditional services have been transferred to the network environment for implementation, such as financial transactions and enterprise management. Due to the fragility of the network environment, the server often needs to be maintained. Once the server is in the maintenance state, if the necessary measures are not taken, the services provided will be interrupted for a long time. For enterprise-level applications, such a long service interruption is unacceptable. [0003] In order to overcome the above-mentioned problems, today's high-availability clusters enable server systems to run uninterrupted, and the server systems generally consist of two or more nodes. If a node needs maintenance, the service process on the node will be migra...
