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： The present invention relates to an access node (2) for connecting a subscriber device (1) to an IPv6-capable aggregation network (3),and adapted to receive an upstream IPv6 packet (Ns1O; RS1O; NA1O) comprising an IPv6 address (LLIP@O) held by the subscriber device.An access node according to the invention is further adapted to assign a new interface identifier (IDT) to the subscriber device that is unique within the scope of a L2 communication domain (6), which the subscriber device belongs to,to substitute, within the upstream IPv6 packet, the new interface identifier for an original interface identifier (IDO) of the IPv6 address, thereby yielding a translated upstream IPv6 packet (Ns1T; Rs1T; NA1T) comprising a translated IPv6 address (LLIP@T), and to forward the translated upstream IPv6 packet towards the aggregation network. The present invention also relates to a method for connecting a subscriber device to an IPv6-capable aggregation network.
摘要翻译：本发明涉及一种用于将用户设备（1）连接到能够支持IPv6的聚合网络（3）的接入节点（2），并且适用于接收包括IPv6地址的上行IPv6分组（Ns1O; RS1O; NA1O） LLIP @ O）由用户设备持有。根据本发明的接入节点还适用于在用户设备所属的L2通信域（6）的范围内为用户设备分配新的接口标识符（IDT），以在其内部替换上行IPv6分组，用于IPv6地址的原始接口标识符（IDO）的新接口标识符，从而产生包含翻译的IPv6地址（LLIP @ T）的翻译的上游IPv6分组（Ns1T; Rs1T; NA1T），并转发将上游IPv6数据包转发到聚合网络。本发明还涉及一种将用户设备连接到具有IPv6能力的聚合网络的方法。

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： The present invention relates to an access control unit (21) of a data communication network (61) comprising an access control means (101) adapted to receive an authorization (111) from an authentication server (51), whereby a particular user (15) is authorized to access said data communication network, and thereupon to grant said particular user an access (106) to said data communication network. An access control unit according to the invention is characterized in that said access control means is further adapted to derive, from an additional information element (112) encoded into said authorization, an association (114) for said particular user between a particular payload type (Ipv6) and a particular virtual network (VLAN2) overlaying over said data communication network, and in that said access control unit further comprises a frame classifier (102) coupled to said access control means (via 103), and adapted to tag particular untagged frames (121) entering said data communication network, related to said particular user and carrying said particular payload type, with a particular virtual network identifier (VID2) of said particular virtual network. The present invention also relates to a method for controlling the access to a data communication network, and to an authentication server for use in cooperation with the access control unit.

摘要： The present invention is applicable to access networks across which virtual connections have been provisioned to meet traffic and QoS requirements. The present invention improves service integrity by controlling the right for a service instance to use the network resources that have been provisioned for its class of service. Whenever a subscriber requests a service that requires a pre-determined bandwidth with a pre-determined QoS, one checks whether the virtual connection over which the service will be delivered to the subscriber can convey the required bandwidth with the required QoS. According to the check outcome, the service is granted or denied to the subscriber. The present invention may further improve the usage of the network resources. This second object is achieved by adapting the configuration of the access network according to the real traffic demand.
