摘要： An in-band diagnostic tool and method are described herein that are capable of retrieving subscriber information from one or more nodes located within a layer 2 aggregation network. In one application, the diagnostic tool and method can be used by a customer service representative to retrieve subscriber information (e.g., user privileges, current bandwidth usage, available bandwidth) related to a customer that receives television, Internet etc. from an Internet Protocol Television (IPTV) network (which is an application-specific layer 2 aggregation network).

摘要： An access node (e.g., DSLAM, OLT/ONT) is described herein that implements a trust verification method comprising the steps of: (a) filtering an up-stream message initiated by a non-trusted device (e.g., CPE); (b) intercepting the filtered up-stream message if the filtered up-stream message is a connectivity fault management message (e.g., LB message, LBR message, CC message); (c) inserting a trusted identification into the intercepted up-stream message; and (d) outputting the intercepted up-stream message with the inserted trusted identification. Thereafter, a trusted device (e.g., BRAS) receives and analyzes the outputted up-stream message with the inserted trusted identification message to ascertain a trustworthiness of the non-trusted device (e.g., CPE). Several different ways that an access network (e.g., IPTV network) can implement the trust verification method are also described herein.

摘要： A network management system and a method are described herein that determine if one or more devices (e.g., consumer premises equipment(s)) are experiencing an unacceptable packet loss for downstream multicast traffic in an access network. In one embodiment, the network management system performs the following operations: (1) cause a trigger probe to be sent to the one or more devices, where each trigger probe contains information which causes the corresponding device to start a packet loss measurement; and (2) receive an unacceptable loss measurement message from one of the devices if that one device experienced packet losses over a certain period of time that exceeded a predetermined threshold which would be an indication that the one end device is experiencing an unacceptable packet loss.

摘要： An access node (e.g., Digital Subscriber Line Access Multiplexer) and a method are described herein that proactively monitor the connectivity of one or more end devices (e.g., residential gateways). In one embodiment, the access node performs the following: (a) receives continuity check messages from at least one of the end devices; (b) polls the received continuity check messages to ascertain the connectivity of each end device; and (c) if at least one continuity check message is detected as missing from one of the end devices during the polling step, then an alarm message is sent indicating a loss of connectivity to the one end device. Thereafter, an edge router (e.g., Broadband Network Gateway) would receive the alarm message and know there is no longer a connection to the one end device.

摘要： A system and method for monitoring end nodes using Ethernet Connectivity Fault Management (CFM) in an access network. In one embodiment, a broadband access server (BRAS) is operable to generate an Ethernet CFM frame that includes a query message with respect to a particular end node. An interworking function (IWF) entity associated with an access node that services the particular end node is operable to interpret the Ethernet CFM frame and construct a corresponding query message in a native protocol compatible with the particular end node. Upon receiving a reply message from the particular end node, the IWF entity constructs a suitable reply Ethernet CFM frame for transmission to the BRAS, wherein the reply Ethernet CFM frame includes a response corresponding to the reply message from the end node.

摘要： A computer-implemented method for facilitating DHCP diagnostic functionality comprises a plurality of operation. An operation is performed for identifying misconfigurations to a DHCP option configuration of a DHCP agent between a DHCP server and a client of the DHCP server. An operation is performed for confirming proper address concentration configuration with respect to the DHCP agent. An operation is performed for snooping on address assignments from the DHCP server to the client of the DHCP server to determine unauthorized ones of the address assignments.
