    • Described is a technology including an Ethernet layer 2 protocol by which a node of a computer network can discover information about other network computing elements, including discovering network topology information, and/or collecting diagnostic information. The protocol allows multiple responders to communicate data with a mapper node for topology discovery, with one or more enumerator nodes for quick enumeration, or with a controller node for network tests that collect diagnostic information. The responders process the received data to determine the type of service (quick discovery, topology discovery or network test) and the service type's related function, and take action based on these and possibly additional criteria in the data. Actions may include responding to the data, following received commands, collecting statistics, responding to queries, and so forth.
    • 描述了一种技术,其包括以太网层2协议,计算机网络的节点可以通过该以太网层协议发现关于其他网络计算元件的信息,包括发现网络拓扑信息和/或收集诊断信息。 该协议允许多个响应者与映射器节点进行数据传输以进行拓扑发现,具有一个或多个枚举器节点用于快速枚举,或者与用于收集诊断信息的网络测试的控制器节点进行通信。 响应者处理接收的数据以确定服务类型(快速发现,拓扑发现或网络测试)和服务类型的相关功能,并根据数据中的这些可能的附加标准采取行动。 操作可能包括响应数据,接收到的命令,收集统计信息,响应查询等。
