AI Technical Summary

Technical Problem

Traditional cluster device firmware batch upgrade solutions rely on external management tools, resulting in high deployment and maintenance costs, low reliability, and susceptibility to network outages and human error, making it difficult to balance reliability and efficiency in the upgrade process.

Method used

By generating encrypted access credentials to build an upgrade cluster, splitting the firmware image into fragments and establishing a mapping table, collecting node status information to construct a topology structure, predicting node write time to generate a zero-wait transmission sequence, transmitting missing fragments on demand, and skipping existing fragments, the cluster enables collaborative upgrades of nodes.

Benefits of technology

It enables secure, efficient, and low-redundancy cluster firmware upgrades, improves bandwidth utilization and upgrade reliability, reduces reliance on external tools, and enhances overall distribution efficiency.

Abstract

The application discloses a cluster upgrading method and electronic equipment, and relates to the technical field of equipment upgrading, and comprises the following steps: generating an encrypted access credential and broadcasting, joining the upgrading cluster and locking the node whose credential verification is passed; cutting the firmware image into multiple fragments, and establishing a fragment mapping table; collecting the state information of each node in the upgrading cluster, calculating the node score and constructing a topology structure, determining the transmission path of the fragments in the upgrading cluster; predicting the time for each node to complete the fragment writing, generating a zero-waiting transmission sequence, and determining the distribution timing of the fragments along the transmission path; querying the fragment mapping table to determine the missing fragments of each node, determining the receiving node according to the transmission path, and transmitting the corresponding missing fragments to the receiving node according to the distribution timing; if the node already holds the corresponding fragment, the transmission is skipped. In this way, the safe, efficient and low-redundancy cluster self-coordinated firmware upgrading is realized, the bandwidth utilization and upgrading reliability are improved, and the dependence on external tools is reduced.
