摘要： A method for operating a computer network has a source router transmit a first message to be received by an intermediate router of the computer network, the first message to activate the intermediate router to listen for a designated time period for the intermediate router to receive a second message. Upon receiving a second message by the intermediate router during the designated time period, the intermediate router responds to the second message in response to receiving the second message during the designated time period.

摘要： A control mechanism enables a destination router to authenticate a response time request issued by a source router. The control mechanism uses a control message that is transmitted by the source router to the destination router. Receipt of the control message by the destination router causes the destination router to listen for a server request message for a designated response time. The source router, after sending the control message, transmits a server request message to the destination router. In the event that the destination router receives the server request message within the designated response time, then the destination router responds to the server request message by providing the request to service software. The control message may encapsulate a message that holds the response time request. The request message may be encrypted.

摘要： The invention provides a control mechanism that enables a destination router to authenticate response time requests issued by a source router before providing the requests to service software for processing. The control mechanism comprises a Network Endpoint Control Protocol (NECP) message format that is exchanged between the source and destination routers when measuring response time throughout the network. The NECP message format encapsulates a Command Length Status Data (CLSD) message that actually holds the response time requests. A collector router issues a novel control message to a responder router over a default responder port. If the responder is enabled for encryption communication, it will decrypt the control message according to the specified key and algorithm. If the responder is not so configured, it will check a conventional ACL to determine whether the client is authorized to communicate with the server. If permitted, the responder then responds to the collector in a manner dependent upon the particular protocol. In the case of a request to enable a UDP port for a particular time period, the responder processes a request and then sends back an acknowledgment to the collector. The collector receives the acknowledgment and then sends out a UDP probe packet to the responder. The responder then “echoes” the packet back to the collector, which keeps the result.
摘要翻译： 本发明提供了一种控制机制，其使得目的路由器能够在向处理服务软件提供请求之前，验证源路由器发出的响应时间请求。 控制机制包括当测量整个网络的响应时间时，在源路由器和目的地路由器之间交换的网络端点控制协议（NECP）消息格式。 NECP消息格式封装了实际保存响应时间请求的命令长度状态数据（CLSD）消息。 收集器路由器通过默认响应端口向响应者路由器发出新颖的控制消息。 如果响应者启用加密通信，则会根据指定的密钥和算法对控制消息进行解密。 如果响应者未配置，则会检查传统的ACL，以确定客户端是否被授权与服务器进行通信。 如果允许，则响应者以取决于特定协议的方式响应于收集器。 在特定时间段内启用UDP端口的请求的情况下，响应者处理请求，然后将确认发回给收集器。 收件人收到确认，然后向响应者发出一个UDP探测包。 然后响应者将数据包“回显”回收集器，从而保持结果。

摘要： A method and apparatus for accurately calculating packet loss along a communication channel using data in a pair of measuring packets is disclosed. The invention calculates packet loss between a first and second node over a communication circuit. A first known quantity of packets is communicated from the first node to the second node at a first known time. A first actual count of packets received by the second node from the first known quantity of packets is then determined. A second known quantity of packets is then communicated from the first node to the second node at a second known time. A second actual count of packets received by the second node from the second known quantity of packets is then determined. The difference between the first known quantity of packets communicated at the first known time and the second known quantity of packets communicated at the second known time is calculated to obtain a value for “packets sent”. The difference between the first actual count of packets received and the second actual count of packets received is calculated to obtain a value for “packets received”. The difference between the packets sent and the packets received provides a value for “packet loss” between the first known time and second known time.

摘要： The invention is directed to a system and method for accurately determining the latency of a selected path within a computer network. First, a setup or signaling protocol is used to establish a bi-directional path state that is associated with a given traffic flow having predefined parameters at each intermediary node along the selected path. Once the path states are established, a source entity disposed at a first end of the selected path formulates and transmits a test message carrying a time record or time stamp to a receiver disposed at the opposite end of the selected path. The test message is configured in accordance with the predefined traffic flow parameters, but does not include any options. By virtue of the previously established path states at each node, the message is forwarded along the selected path without incurring any route or option processing delays. Upon receipt of the test message at the receiver, it is returned back to the source, and again follows the selected path. By comparing the time at which the test message is returned with the time record contained within the message, an accurate determination of the latency of the selected path may be determined.
