Abstract: In an optical line terminal connectable to optical network units in an optical communication network, an receiver converts an upstream optical signal, received from an optical network unit, into a corresponding upstream electric signal and then derives an upstream control signal controlling the optical line terminal from the upstream electric signal. A controller generates a power control signal switching on or off power supply to the receiver on the basis of the upstream control signal, and a power feeder switches on or off the power supply to the receiver in response to the power control signal. Thus, the optical line terminal can reduce the waste of standby electricity.

Abstract translation: 在连接光通信网络中的光网络单元的光线路终端中，接收机将从光网络单元接收到的上行光信号转换成对应的上行电信号，然后将控制光线路终端的上行控制信号 上游电信号。 控制器基于上游控制信号产生接收或接通电源的功率控制信号，并且电源馈送器根据功率控制信号接通或关断接收机的电源。 因此，光线路终端可以减少备用电力的浪费。

Abstract: A user's set top box (STB), or other client, executes a shell and has an application program interface (API) by which certain features of the client can be controlled. The client is in communication with a walled garden proxy server (WGPS). The client sends a request to the WGPS to access a service provided by a site in the garden. The site sends the client a message containing code calling a function in the API. The WGPS traps the message from the site and looks up the site in a table to determine the access control list (ACL) for the site. The WGPS includes the ACL in the header of the hypertext transport protocol (HTTP) message to the client. The shell receives the message and extracts the ACL. If the code lacks permission, the shell stops execution.

Abstract: A computer-implemented system and method for managing service requests are disclosed. The system includes a service provider, having a number of server devices, that provides a service response in response to a client service request. The service response includes a service instance ID associated with a server and a connection lease. A communication processing component routes a first client service request to one of the servers. Subsequent client service requests and responses are transmitted directly between the client device and the server device associated with service instance ID included in the first service response for the duration of the connection lease.

Abstract: Disclosed is a scalable, hierarchical, distributed network architecture and processes for the delivery of high-performance, end-to-end online multimedia services, including Internet services such as World Wide Web access. The network architecture connects a high-speed private backbone to multiple network access points of the Internet, to a network operation center, to a back office system, and to multiple regional servers in regional data centers. Each of the regional servers connects to several caching servers in modified head-ends, which in turn connect via fiber optics to many neighborhood nodes. Finally, each node connects via coaxial cable to multiple end-user systems. The processes include those for replicating and caching frequently-accessed content, and multicasting content customized per region or locality.

Abstract: In one embodiment, a first ranging timing description describing at least a duration of time during which a subject cable modem (CM) may burst and a duration of time during which the subject CM and other CMs in a multiple access network are not permitted to burst is translated into a second ranging timing description describing a duration during which a burst from the subject CM is expected to be received by a cable modem termination system (CMTS). The CMTS is conditioned to receive a burst from the subject CM during the duration of time described by the second ranging timing description. A timing offset is determined from at least an actual time a burst from the subject CM is received by the CMTS and the duration of time during which the subject CM and other CMs in the multiple access network are not permitted to burst to produce a determined timing offset. The determined timing offset is reported to compensate for delay in the multiple access network and the subject CM.

Abstract: In one embodiment, a processing device is coupled between at least one content source and at least one subscriber device within an Internet Protocol television (IPTV) system in order to receive a plurality of service flows from the at least one content source and to process multicast service flow requests from the at least one subscriber device. The processing device includes a map module to map a service flow from a content source to a multicast service flow based on a multicast service flow request from a particular subscriber device and a unicast module to assign a unique identifier to the mapped multicast service flow to convert the mapped multicast service flow to a unicast delivery of the mapped multicast service flow to the particular subscriber device.

Abstract: A system and method for facilitating communication between a CMTS and an application sever in a cable network. Customer premises equipment (CPE) generates packets that are sent through a cable modem (CM) to a cable modem termination system (CMTS). A packet is parsed by CMTS and the destination IP address and port number compared to the destination IP address-port tuples received by the CMTS from a datastore. A packet that is directed to an IP address-port tuple on the target list (a “service request packet”) is modified to incorporate CMTS-identifying information and subscriber-identifying information in the packet header. When the application server communicates with the CMTS to reserve the network resources, the application server provides the CMTS with the CM MAC and CM IP addresses to facilitate resource allocation, subscriber identification and billing.

Abstract: An arrangement and method for relieving the traffic load on an edge node in a broadband Ethernet-based access network, which normally employs traffic separation such that all traffic is routed via the edge node. Peer-to-peer traffic between end users places a large burden on the capacity of the edge node. The edge node identifies peer-to-peer traffic and generates address conversion information for access nodes connected to the end users concerned. The access nodes identify packets forming part of the peer-to-peer connection, modify address information to conceal the address of the source end user from the destination end user, and vice versa, and reroute the packets through the access network to the destination end user without passing through the edge node.

Abstract: A method of configuring a network element such that a Virtual Private Network (VPN) site can connect to the network element is disclosed. An interface on a Provider Edge (PE) router is configured in restricted mode. A request is received from the interface to authenticate a user associated with a VPN requesting to connect to the interface. A determination is made as to whether the user is authorized to submit requests to the interface. If the user is authorized, an activation request is received from the interface to allow the VPN can connect to the interface. A determination is made as to whether the user is authorized to connect to the interface via the VPN. If the user is authorized, VPN site parameters are configured at the PE router and the PE router is configured in unrestricted mode.
