摘要： In one embodiment, a method includes identifying at least one parameter as being associated with a service provided to an entity, as for example a subscriber. The service is arranged to service the entity. The method also includes monitoring the parameter to determine if accessibility to the service by the entity is compromised, and invoking a notification mechanism to send a notification to the entity if it is determined that the accessibility to the service by the entity is compromised. The notification indicates that the accessibility to the service is compromised.

摘要： In one embodiment, an aggregation device operating in a computer network may have a down maintenance end point (MEP) configured on certain of its user-to-network interface (UNI) ports. These down MEPs may then receive continuity check messages (CCMs) from down MEPs configured on customer edge (CE) devices, where each CCM has a media access control (MAC) address of a corresponding CE device UNI port from which the CCM is transmitted. In response to detecting conflicting MAC addresses between CE device UNI ports based on the CCMs, the aggregation device may notify the CE devices corresponding to the conflicting MAC addresses of the conflict.
摘要翻译：在一个实施例中，在计算机网络中操作的聚合设备可以具有在其某些用户到网络接口（UNI）端口上配置的下行维护端点（MEP）。然后，这些下行MEP可以从客户边缘（CE）设备上配置的下行MEP接收连续性检查消息（CCM），其中每个CCM具有从其发送CCM的相应CE设备UNI端口的媒体访问控制（MAC）地址。响应于基于CCM检测CE设备UNI端口之间的冲突MAC地址，聚合设备可以通知冲突MAC冲突的对应CE设备。

摘要： A method of operation for a node of an Ethernet access network includes issuing a multicast message on the Ethernet access network by a maintenance end point (MEP) of the node. The multicast message contains a name of a target MEP. The node is further operable to receive a unicast reply message from the target MEP, the unicast message reply containing a MEP identifier (MEP-ID) and a MEP Media Access Control (MAC) address of the target MEP.

摘要： A broadband access node includes a port for connection with a Digital Subscriber Line and a processor to run code that implements a virtual maintenance end point (vMEP). The vMEP translates an IEEE 802.1ag Loopback Message (LBM) received from a device on an Ethernet access network into a legacy operations and maintenance (OAM) message that is transmitted to a residential gateway (RG) device. The legacy OAM message determines a link-level connectivity status between broadband access node and the RG device. The vMEP also transmits a reply message back to the device on an Ethernet access network in compliance with the IEEE 802.1ag specification. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

摘要： A technique dynamically delivers multicast service notification messages in a computer network. According to the novel technique, a service provider (SP) network device determines if it is able to deliver a particular requested multicast service (stream) to a subscriber device, e.g., whether there is enough bandwidth, sufficient quality of service (QoS), appropriate access rights of the subscriber, and/or external triggers, etc. In the event it is unable to deliver the multicast service, the SP network device returns a network-based notification message (e.g., low bandwidth video, audio, data, etc.) using the same communication format as the requested multicast service as though the notification message were the requested multicast service itself. The notification message may be masked such that the subscriber device is substantially unaware that the notification is not the requested multicast service, or the subscriber device may be instructed to display a particular locally cached notification message.
摘要翻译：技术在计算机网络中动态地传送多播服务通知消息。根据新技术，服务提供商（SP）网络设备确定是否能够将特定请求的多播服务（流）传送到用户设备，例如，是否存在足够的带宽，足够的服务质量（QoS）用户的适当访问权限和/或外部触发器等。在无法传送多播服务的情况下，SP网络设备返回基于网络的通知消息（例如，低带宽视频，音频，数据等）使用与所请求的多播服务相同的通信格式，就像通知消息是所请求的多播服务本身一样。通知消息可以被屏蔽，使得用户设备基本上不知道该通知不是所请求的多播服务，或者可以指示订户设备来显示特定的本地缓存的通知消息。

摘要： Techniques for authenticating a user for access to an IP network include receiving from the user's host a DHCP request which includes user identifier data. A random challenge value is determined and sent to the user's host in a DHCP message format. A response message that includes a response value is received from the user's host in DHCP format. A verification value is determined based on a password value associated with the user identifier value in an AAA server and the current challenge value using a secure process that renders impractical an attempt to derive the password. If it is determined that the response value does not match the verification value, then a DHCP offer is prevented from being sent to the user's host in response to the DHCP request. Thus, a user is authenticated using DHCP instead of PPP.
摘要翻译：用于验证用户访问IP网络的技术包括从用户的主机接收包括用户标识符数据的DHCP请求。确定随机挑战值，并以DHCP消息格式发送给用户的主机。包含响应值的响应消息以DHCP格式从用户主机接收。基于与AAA服务器中的用户标识符值相关联的密码值和使用不切实际的尝试导出密码的安全过程来确定当前挑战值的验证值。如果确定响应值与验证值不匹配，则可以防止响应于DHCP请求向DHCP用户的主机发送DHCP报文。因此，使用DHCP而不是PPP进行身份验证。

摘要： One embodiment includes, inter alia, methods, apparatus, computer-storage media, mechanisms, and/or means associated with automated transitioning between different communication protocols in a network. In one embodiment, automatic transition routers are automatically discovered along with the knowledge of what non-native protocols need to be transported across a network. Communication pathways are automatically established as needed to transport these non-native protocols. One embodiment is particularly useful in transitioning a network from one protocol to another, such as from Internet Protocol version 4 to version 6.

摘要： A method is provided in one example and includes receiving signaling data associated with a request for a multicast channel, the request includes an Internet protocol version 6 (IPv6) source and an IPv6 group address. The method may also include identifying an Internet protocol version 4 (IPv4) source and an IPv4 group address to be mapped to the IPv6 source and the IPv6 group address. The signaling data can be converted from a first protocol to a second protocol. The converted signaling data can be communicated to a network element. In more particular embodiments, the network element is an IP edge router configured to join the multicast channel and stream data in response to receiving the converted signaling data. The IP edge router can be configured to perform an encapsulation operation to transport IPv6 multicast packets within an IPv4 multicast channel.
