摘要： A delay measurement technique according to an embodiment according to the present invention is based on the precept, ascertained by the inventors, that a link between network nodes will often contribute to the delay encountered between several different pairs of network nodes. Such a technique identifies the path between each pair of nodes by a list of links that form the path. Paths that are orthogonal are treated as being necessary for describing the delays encountered between nodes, and, once the requisite set of orthogonal paths has been derived, all other paths can be described in terms of one or more of these orthogonal paths. Such a technique also lends itself to matrix representation of the paths, and the use of matrix manipulation techniques in deriving delay and jitter.

摘要： A system in which a single VLAN architecture spans multiple VLAN transport protocols and technologies, including a method and system in which multiple different VLANs may be combined in a single enterprise network. Each LAN-switch in the system identifies each frame with an identifier, and associates that identifier with particular VLAN identifiers for each type of VLAN technology. When a frame is bridged or routed from a first type of VLAN to a second type of VLAN, the first VLAN encapsulation is removed and the second VLAN encapsulation is added, with appropriate change in the VLAN identifier for the frame or packet. The identifier may also be implicit for the frame, such as when a particular set of sender's MAC addresses are identified with a particular VLAN. Individual VLANs, of whatever architecture, may be added, configured or reconfigured, modified, or deleted, using control tools associated with the multiple VLAN architecture system. Individual ports may be associated with particular VLANS, or may be designated “dynamic” so that frames or packets associated with those ports are associated with particular VLANs in response to source or destination addresses or other information.
摘要翻译：单个VLAN架构跨越多个VLAN传输协议和技术的系统，包括可以在单个企业网络中组合多个不同VLAN的方法和系统。系统中的每个LAN交换机用标识符识别每个帧，并将该标识符与每种类型的VLAN技术的特定VLAN标识相关联。当帧从第一种类型的VLAN桥接或路由到第二种类型的VLAN时，将删除第一个VLAN封装，并添加第二个VLAN封装，并适当更改帧或数据包的VLAN标识。该标识符对于该帧也可以是隐式的，诸如当用特定VLAN识别特定发送者的MAC地址集合时。可以使用与多VLAN架构系统相关联的控制工具，添加，配置或重新配置，修改或删除任何架构的各个VLAN。单个端口可以与特定VLAN相关联，或者可以被指定为“动态”，使得与这些端口相关联的帧或分组响应于源或目的地地址或其他信息与特定VLAN相关联。

摘要： A method and apparatus are disclosed for managing network devices using a parsable string that conforms to a specified grammar. The parsable string is used to represent locations of entities and is called an entity location specifier. The grammar may conform to Augmented Backus-Naur Form (ABNF). The entity location specifier comprises one or more location elements taken from a superset of location elements needed to specify the locations of entities for network device platforms. The superset of location elements can include both physical and logical entities. As a result, a network management application can retrieve a description of entities and elements contained in a network device using a single request, and can receive a single string value that is parsable to identify individual entities or elements in the device.
