Abstract: At a customer premises equipment comprising one or more network interfaces, an instruction to provision a slice of the customer premises equipment (CPE) for a tenant application is received from a root network manager. The instruction identifies at least one network interface of the one or more network interfaces to allocate to the slice. The slice of the CPE is provisioned, where provisioning the slice comprises allocating CPE resources including the at least one network interface to the slice of the customer premises equipment. The tenant application is obtained. Data associating the tenant application with the slice of the CPE is stored. A management instruction for managing the tenant application is received directly from a secondary network manager associated with the tenant application. The management instruction is executed only in relation to the slice.

Abstract: A method and apparatus for mixing first and second video content portions is described. The method may comprise overlapping at least one frame of a first content portion comprising multiple frames with at least one frame of a second content portion comprising multiple frames to produce a composite video content. At least one reference frame comprising a frame of the first or second content portion prior to the overlapping may be designated. The composite video content and the reference frame may then be transmitted, for example, to a client device. The client device may use the reference frame to at least reduce an effect of the overlapping.

Abstract: In one embodiment, a method includes receiving gap information from an entertainment content source configured to provide an entertainment stream associated with a contributing source information providing a source of the entertainment stream and a chronological order to render the entertainment stream, the entertainment stream being encrypted and having an associated first decryption key multiplexed into a key distribution system, the gap information identifying a gap in the entertainment stream where an ad may be one of inserted or substituted, synchronizing a target ad from an advertisement stream to a time base corresponding to the gap, decrypting the entertainment stream using the first decryption key selected from the key distribution system based on the contributing source information, and rendering the entertainment stream and the target ad as a composite stream based on the chronological order, the target ad being rendered during the gap in the entertainment stream.

Abstract: One embodiment of an inventive networking environment includes clients called sending clients because they send network content through a network, and clients called receiving clients because they receive the network content from the sending clients through the network. Both sending clients and receiving clients are “clients” in that they rely on a management server to orchestrate the secure transfer of information from sending clients to receiving clients.

Abstract: A method of communicating messages across a network is provided. A router receives an RSVP (Resource Reservation Protocol) PATH message from a sending host that is directed to a receiving host. Upon identifying the protocol of the incoming PATH message as RSVP, the router accesses a proxy look-up table to identify a proxy host acting on behalf of the receiving host. The router then adds a proxy header to the PATH message and redirects the PATH message to the proxy host by sending the message to a predetermined port. The proxy host receives the PATH message and, in response, sends a resource reservation request (RESV) message onto the network with a proxy header and directed to the predetermined port. The router receives the RESV message, strips off the proxy header, and forwards the RESV message to the sending host as if the message had originated from the receiving host. A proxy host can also send PATH messages on behalf of the sending host.

Abstract: A data processing system for regulating access to a communication network is disclosed herein. The data processing system employs a component that can be implemented in hardware logic or software. The component regulates access to the priority queue or transmit channel that is attached to the shared medium local area network section. All access to the priority queue or transmit channel must pass through this component, thus subjecting all communication transactions to rejection or tracking by the component. The component allocates a frame size based on the information to be transmitted and the priority to assure the transmission will be completed in line with the quality of service required. The component monitors the rate and size of messages to assure that an application's actual throughput does not exceed its negotiated throughput. The component, moreover, is capable of operating in correction mode where throughput and frame size violations are prevented and reported.

Abstract: A method for providing files to a remote node including the steps of determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, reserving bandwidth for the requested file if bandwidth is determined to be available, and opening the requested file for transmission only if bandwidth is reserved. In addition, an apparatus for providing files to a remote node including apparatus for determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, apparatus for reserving bandwidth for the requested file if bandwidth is determined to be available, and apparatus for opening the requested file for transmission only if bandwidth is reserved.

Abstract: A system and method is provided to compliment use of priority for reserved traffic in multimedia computerized data communication networks, to insure that the opportunity for transmitting large, unreserved data frames is constrained. If frames transmitted when the server releases a token tend to be small, then the server will capture a larger portion of the bandwidth. Thus, a short bandwidth reservation acknowledgement is transmitted onto the ring by the client for selected frames which it receives. This is not addressed to any station on the ring. Rather it is simply transmitted at a non-zero priority less than the server's priority. The criteria which is employed by the client for such acknowledgement is that the sender will send a bandwidth reservation acknowledgement only when the IEEE 802.5 AC field is set, but will do so for a fixed amount of time or for a fixed number of received frames.
