Embodiment Construction

[0019] In order to solve the problems existing in the existing technology, the embodiment of the present invention improves the version upgrade scheme of the existing communication system, wherein, after the upgrade of the backup device is completed and before the upgrade of the master device, the master device upgrades the The forwarding table entries are synchronized to the standby device, and the standby device will synchronize the forwarding table entries to the active device after the upgrade of the active device is completed, so that the active device and the standby device do not need to re-learn the forwarding entries after the upgrade is completed, and further It avoids the problem of long-term disconnection caused by re-learning forwarding entries of the active device and the standby device after the upgrade is completed.

[0020] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention discloses a system upgrading method and a system upgrading device, which are applied to a communication system comprising first equipment and second equipment. Before the system is upgraded, the first equipment serves as standby equipment, and the second equipment serves as master equipment. The method comprises the following steps of: performing system version upgrading on the first equipment, and after the system version upgrading of the first equipment is finished and the first equipment is restarted, performing version upgrading on the second equipment, wherein the first equipment is restarted after the system version upgrading of the first equipment is finished, and a user port on the first equipment is blocked; the first equipment receives a forwarding table entry synchronized by the second equipment, is configured with the forwarding table entry, enables the blocked user port of the first equipment according to a port enabling notice received from the second equipment, and is upgraded into the master equipment after the port is enabled; and after the system version upgrading of the second equipment is finished and the second equipment is restarted, the first equipment synchronizes the forwarding table entry on the first equipment to the second equipment. By the method and the device, the long-term forwarding table entry learning process, caused by the version upgrading, of the system can be avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system upgrading method and device thereof. Background technique [0002] Currently, in large and medium-sized data center network applications, the core equipment adopts an IRF (Intelligent Resilient Framework) environment, and the IRF environment consists of two or more equipment. When upgrading the version, it is necessary to consider the impact on the actual business. When the new version is compatible with the old version, it is possible to ensure that the business is not affected during the upgrade process. If the new version is not compatible with the old version, there will be a period of packet loss during the upgrade process. If the time period is too long (for example, more than 50 seconds ), it is unacceptable for medium and large data centers. [0003] The upgrade process in the case of incompatibility between the new and old versions may include: first upg...
