摘要： An apparatus for and method of packet loss measurement for TLS connections in an MEN that overcomes the problems of the prior art. The mechanism is operative to ensure that only one copy of each received packet is counted when exiting the TLS connection (unless dropped along the path due to congestion, etc.), so that the number of egress packets counted can be accurately compared with the number of ingress packets counted. Only a single copy of each packet is marked, i.e. flagged, at ingress. Any bridging along the path that needs to duplicate the packet forwards only a single marked copy of the packet. All other copies are forwarded unmarked. At the egress from the TLS, only marked packets are counted by the egress counter. In a second embodiment, a duplication field is inserted into each packet to better track all the duplicate copies of a packet.

摘要： This invention discloses a method for detecting a layout of a switched local network including at least one switching hub connected to a first plurality of elements, each identified by an address, via a corresponding second plurality of ports defining a corresponding second plurality of element to port connections, the method including determining all element to port connections for each switching hub, identifying the elements which communicate via each of that switching hub's backbone ports and based on the element to port connections and the elements communicating via each switching hub's backbone ports, determining the layout of the switched local network.An apparatus for monitoring a layout of a local network, the network including a first plurality of ports associated, via end-station to port connections, with a second plurality of end-stations is also disclosed.
