Abstract: A server device delivers content to a client device by sending the content as a series of segments using chunked delivery. The sending is paced in accordance with a class of service for the client device, the class of service having an associated target chunk send time that decreases with higher classes of service. Pacing includes sending a chunk over an actual chunk send time and calculating an inter-chunk delay as a difference between the target chunk send time and the actual chunk send time. If the inter-chunk delay is positive, then the server waits the inter-chunk delay before beginning to send a next successive chunk, and otherwise it immediately begins sending the next successive chunk. The server also employs bitrate selection to manage client use of available bandwidth.

Abstract: Apparatuses and methods control communication of content streams through a content distribution network. A data repository is accessed to retrieve information which identifies a group of user equipment nodes that are registered with one of a plurality of subscriber accounts and which further identifies weight values that are associated with the group of the user equipment nodes. Communication bit rates that are provided by a weighted fair queuing scheduler node to individual ones of a group of the content streams within bandwidth allocated to a virtual pipe for carrying the group of the content streams through the content distribution network to the group of the user equipment nodes, are regulated responsive to the weight values associated with the group of the user equipment nodes. Weighted fair queuing scheduling can thereby be provided at a virtual pipe level and, furthermore, at a user equipment node level.

Abstract: A method and device for communicating information resources between subscriber end stations and nodes belonging to different network domains is described. The device instantiates different virtual network machines for different network domains using separate independently administrable network databases. Each of the administrable chores of the separate independently administrable network databases includes the assignment of access control and the configuration of the policies for those network databases. The policies include traffic filtering policies to indicate what kind of information payloads can be carried, traffic and route filtering policies to indicate what paths through the network will be used for each payload carried. Each of the network domains includes one of the different virtual network machines and each of the different network domains is virtually isolated from other network domains.

Abstract: A method implemented by a network service provider to provide a virtual network to tenants requiring bandwidth in a cloud computing environment, where the virtual network includes a first set of one or more virtual switches that manage a second set of one or more physical servers that host virtual machines (VMs). The method starts with receiving by one virtual switch a request for a first plurality of VMs, where at least one VM of the first plurality of VMs contains a bandwidth different from bandwidths of the rest of one or more VMs. The it is determined whether to accept the request for the first plurality of VMs by calculating a set of allocation ranges (ARs) associated to the virtual switch, wherein each AR of the set of ARs denotes at least one discontinuous VM allocation space within a virtual switch. Then VMs are allocated for the request.

Abstract: A call set-up system sets up a call, which may be a voice call, between terminals through a plurality of packet switched networks using call agents. The networks are interconnected by network address translation (NAT) devices, and the messages to successive call agents include media addresses in the associated networks for the actual data packets of the call when it has been set up. The call set-up message includes the media address sent to at least some preceding call agents enabling NAT resources to be saved. The call agents can be incorporated into NAT devices, and the media addresses can be encrypted or in the form of a reference.

Abstract: Techniques for providing resilient multicast traffic processing in a network element are described herein. In one embodiment of the invention, a network element separately joins equivalent multicast traffic streams at a first and second interface respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives at the first interface and drops the packets of the equivalent multicast traffic stream it receives at the second interface. Upon an interruption of the packets of the multicast traffic stream being received at the first interface, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives at the second interface. Other methods and apparatuses are also described.

Abstract: A network node allocates (810), to each of two or more component carriers, a respective power share of a total UE transmit power and calculates (820) a required UE transmit power to achieve a target power density at the network node, where the target power density is the sum of a nominal target power density and a predetermined power density offset. The network node reallocates (830) 5 any excess available UE transmit power over the required UE transmit power for a carrier to another carrier or carriers and calculates (840) an achievable received power density at the network node based on the allocated UE transmit powers. The network node calculates (850) an adjusted power density offset by subtracting the nominal target power density from the achievable received power density, and uses the adjusted power density offset when performing (860) closed-loop power 0 control for the carriers.
