摘要： A method for changing a network characteristic or capability, such as the communication rate of network segments, software version or protocol. All nodes in the network perform the change synchronously while continuing to communicate within the existing capabilities. A new configuration is downloaded to the nodes, and a manager node exchanges validation messages with the other nodes in order to verify that the nodes can be reconfigured and will be able to complete the process successfully. The manager node then sends a command message to the other nodes to execute the change. In response, the other nodes begin substantially simultaneously to communicate in accordance with the new characteristics and/or capabilities. This method helps to minimize the duration of the upgrade process, while avoiding traffic hits and minimizing abnormal operation that may occur during the upgrade.
摘要翻译：一种改变网络特性或能力的方法，如网段的通信速率，软件版本或协议。网络中的所有节点同时进行更改，同时在现有功能中继续通信。新的配置被下载到节点，并且管理器节点与其他节点交换验证消息，以便验证节点可以被重新配置，并且能够成功地完成该过程。然后，经理节点向其他节点发送命令消息来执行更改。作为响应，其他节点基本上同时开始以根据新特性和/或能力进行通信。此方法有助于最大限度地减少升级过程的持续时间，同时避免流量命中并最大限度地减少升级期间可能发生的异常操作。

摘要： According to a disclosed embodiment of the invention, software download and installation in a ring network are synchronized in a two-stage operation in order to minimize service disruption time. In a first phase, the MPM's and UIM's in all the nodes are upgraded in parallel. Each node has two main processing modules, allowing one to be upgraded while the other continues to operate the node. In a second phase, the RIM's at the edges of a single ring segment are upgraded, one ring segment after the other, during which time each terminal node continues to operate with respect to the span connecting to its opposite side. While a span is non-operative, traffic is wrapped or diverted as necessary to maintain service of the ring. While one RIM of a node is being upgraded, the other RIM remains operational.
摘要翻译：根据本发明的公开的实施例，环形网络中的软件下载和安装在两级操作中被同步，以便最小化服务中断时间。在第一阶段，MPM和UIM在所有节点中并行升级。每个节点有两个主要处理模块，允许一个升级，另一个继续运行节点。在第二阶段中，单个环段边缘处的RIM升级，一个环段在另一个之后，在该时间期间，每个终端节点相对于连接到其相对侧的跨度继续操作。当跨度不起作用时，根据需要将流量包裹或转移以维持环的服务。虽然节点的一个RIM正在升级，但是另一个RIM仍然可以运行。
