Title: CAPACITY UPDATING METHOD AND APPARATUS FOR DISTRIBUTED DEVICE
Abstract:
The present application relates to the technical field of communications. Disclosed are a capacity updating method and apparatus for a distributed device. The method comprises: receiving a first distribution table sent by a second device, the first distribution table carrying a CPU identifier sequence, each CPU identifier in the CPU identifier sequence separately indicating a CPU in the second device; determining, from the first distribution table, a CPU identifier corresponding to each state entry in a first device, so as to form a mapping relation between the state entry and the CPU identifier; generating at least one backup packet according to the mapping relation, and after instructing the second device to update the state entry of each CPU included therein, switching to the second device for processing service packets. The backup packet is generated according to the first distribution table, and therefore, after switching to the second device for processing service packets, the second device also performs packet distribution according to the first distribution table, so as to prevent the service packets from being dropped to cause a traffic interruption.
