Problems solved by technology

[0007] When using a new version to upgrade a slave device or master device, if the new version is incompatible with the old version (the version used by the current IRF system), the device cannot join the old version of the IRF system after starting with the new version, that is Devices using the new version will run independently of the original IRF system and will generate a new node in the network, causing network changes and business interruptions

Embodiment Construction

[0044] In the prior art, when the ISSU technology is used, for the frame-type equipment, since the frame-type equipment contains dual main control boards, the standby main control board and the main main control board can be upgraded separately through the 1:1 ISSU upgrade mode. board, so as to ensure that during the upgrade process, there is always a main control board in working condition, which can continuously process various services.

[0045] However, for box-type equipment, since the box-type equipment has only one main control board, and the control plane and service plane are integrated together, it cannot be upgraded by using the above-mentioned ISSU upgrade mode, while using the ISSU technology based on the IRF system for upgrade , The existing IRF system of box-type equipment is upgraded to a new version. If the new version is incompatible with the old version, the equipment using the new version will run independently of the original IRF system, causing network cha...

Abstract

The invention discloses an intelligent resilient framework (IRF) system-based method and an intelligent resilient framework (IRF) system-based system for upgrading an box type equipment. The method comprises the following steps of: upgrading a current version of each equipment in a first group by using a new version, and sharing the service flow of each equipment in the first group to a second group; and upgrading a current version of each equipment in the second group by using the new version, and sharing the service flow of each equipment in the second group to the first group. Through the method and the system, the upgrading of incompatible versions in the box type equipment is realized, so that service is uninterrupted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an IRF system-based box device upgrading method and system. Background technique [0002] In order to ensure that the existing services are not interrupted during the version upgrade process, the ISSU (In-Service Software Upgrade) technology is proposed. Compared with the previous restart of the whole machine, ISSU technology is gradually upgraded to ensure uninterrupted services or minimize the interruption time. [0003] IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) is a software virtualization technology. By connecting multiple devices through IRF physical ports and performing corresponding configurations, they are virtualized into a "distributed device". [0004] Specifically, the IRF system includes a master device and multiple slave devices. When the master leaves, any slave device can take over the work of the master device, thus re...
