Problems solved by technology

[0006] However, when the device undergoing soft restart upgrade is an aggregation layer or core layer device, the aggregation layer or core layer device is usually connected to a large number of other devices and runs many complex services. The CPU of the main control board itself is busy. If the CPU sends the protocol packets sent by the CPU of the interface board on behalf of the CPU, the burden on the CPU of the main control board will be increased; and the CPU of the main control board may not be able to send the protocol packets sent by the CPU of the interface board in time, which will further cause the protocol aging timeout of the peer device. The network topology flaps

Embodiment Construction

[0036] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The embodiment of the present invention proposes an ISSU soft restart upgrade method, which is applied to a network including a local device and a peer device that are directly connected to each other. In this embodiment, the local device needs to perform an ISSU soft restart upgrade as example, such as figure 2 As shown, the method includes the following steps:

[0038] In step 201, the local device obtains a physical interface that needs to send a proxy packet before performing a soft restart upgrade of the ISSU, and sends a packet sending request message to the peer device through the obtained physical interface.

[0039] In the embodiment of the present invention, the proxy packet sending request message is used to indicate that a soft restart upgrade is required, and the proxy packet sending request message carries the protocol type that re...

Abstract

The invention discloses a soft restart upgrading method and equipment of ISSU (In Service Software Upgrade). The method comprises the following steps: before home terminal equipment carries out the soft restart upgrading of ISSU, opposite terminal equipment receives an agent contract request message from home terminal equipment; the opposite terminal equipment records the identification of a physical interface of the received agent contract request message in a port index table; in the soft restart ISSU upgrading process carried out by the home terminal equipment, when the opposite terminal equipment detects that the keep-alive timer of the physical interface is overtime, the port index table is inquired through the physical interface; and if corresponding records exist, the protocal aging treatment is not carried out. In the soft restart upgrading method and equipment of ISSU, the load of a main control panel CPU (Central Processing Unit) can be reduced, and a network topology is prevented from shocking.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an ISSU (In-Service Software Upgrade, uninterrupted service upgrade) soft restart upgrade method and equipment. Background technique [0002] ISSU is a highly reliable way to upgrade device startup software, including incremental upgrade, soft restart upgrade, and restart upgrade. These three methods can achieve uninterrupted services during the upgrade process. Among them, the interface board needs to be upgraded by soft restart, and the main control board needs to be upgraded incrementally or restarted; before the soft restart and upgrade of the interface board, the main control board needs to be upgraded first, and will continue to be in a normal and stable working state. [0003] When the interface board starts soft restart upgrade, it needs to save the running data (such as running data, configuration data, hardware data, etc.) and state in the memory; Centra...
