An asymmetric network communication system for use in a client-server environment having independent forward and return channels operating at different speeds and/or under different protocols on the same or different communication media to provide efficient utilization of shared resources. A network manager, such as a hybrid access system, effects transmission of packetized data on a forward (downstream) channel from the host server to multiple client devices coupled with a shared downstream media at 10 or more megabits per second while simultaneously providing selectable multiple lower speeds of operation on shared or dedicated return (upstream) channels from the client devices to the host server depending on bandwidth availability, bandwidth demand, service level authorization, etc. for the return channel. Forward and return channels may be located on the same or different communication medium including a CATV network, direct broadcast satellite network, television or radio RF broadcast network, wireless or mobile cellular facilities or the like. The return channel may reside on a PSTN either directly coupled with the host server or connected with the network manager for subsequent transmission to the host server. The network manager handles or controls the forward and return communication to establish interactive full-duplex real-time network sessions between the host and a selected client device.
A hybrid access system for communication with at least a single data processor in a network, said system comprising:
In a wide area network that includes a host server, a plurality of remote clients, a headend facility, a high speed interface that connects said headend facility with said host server, and a high speed link for transferring downstream data packets, a method of providing high speed remote access from any of a plurality of client processors each connected to said wide area network including high-speed downstream and lower-speed upstream channels controlled by a hybrid system manager and a router, said method including the steps of:
In a full-duplex asymmetric network communication system for transferring information between a host server and a plurality of remote clients over a shared medium and wherein said remote clients include respective remote link adapters for receiving high speed downstream information from said host server over said shared medium and for transmitting lower speed return information over an upstream channel that is independent of the downstream channel, and wherein said network communication system includes a hybrid access system for providing interactive network sessions in downstream and upstream communication channels, a method of transmitting data from an upstream transmit queue in an upstream transmitter node to a selected receiver node located at a receiving end, said method comprising the steps of:
In a full-duplex asymmetric network communication system for transferring information between a host server and a plurality of remote clients over a shared medium and wherein said remote clients include respective remote link adapters for receiving high speed downstream information from said host server over said shared medium and for transmitting lower speed return information over an upstream channel that is independent of the downstream channel, and wherein said network communication system includes a hybrid access system for providing an interactive network session in downstream and upstream communication channels, a method of dynamically setting remote link adapter power levels in said hybrid access system, comprising the steps of:
In a full-duplex asymmetric network communication system for transferring information from a host server and a plurality of remote clients over a shared medium and wherein said remote clients include respective remote link adapters for receiving high speed downstream information from said host server over said shared medium and for transmitting lower speed return information over an upstream channel that is independent of the downstream channel, and wherein said network communication system includes a hybrid access system for providing an interactive network session in downstream and upstream communication channels, a method of packet suppression in communication between first and second nodes in said communication system having respective first and second transmit and receive queues, in which information packets having headers are transmitted from said first node to said second node, comprising the steps of:
In a full-duplex asymmetric network communication system for transferring information from a host server and a plurality of remote clients over a shared medium and wherein said remote clients include respective remote link adapters for receiving high speed downstream information from said host server over said shared medium and for transmitting lower speed return information over an upstream channel that is independent of the downstream channel, and wherein said network communication system includes a hybrid access system for simultaneously controlling the downstream and upstream in interactive network sessions, a method of dynamically responding to detected quality levels in a communication channel, comprising the steps of:
A network communication system including a server, a plurality of remote clients and an information distribution facility for distributing information signals to said remote clients, said communication system comprising:
In a split-channel asymmetric network communication system including a host server, a plurality of remote clients and a headend facility for distributing information signals to said remote clients, a full-duplex packet delivery system comprising:
A network communication system including a host, a plurality of remote users and an information distribution facility for distributing information signals to said remote users, said system comprising:

In combination with a CATV broadcast transmission facility including a shared medium downstream channel that is shared by a plurality of remote clients to receive high speed data packets from a host server, the improvement comprising:
In combination with a television signal broadcast facility, the improvement comprising:
In combination with a television signal broadcast facility, a network of host computers and a plurality of remote clients, the improvement comprising:
In an asymmetric network communication system including a host server and a plurality of remote clients wherein respective remote clients have associated remote link adapters that operate in accordance with predefined downstream and upstream protocols, said system including:
A packet delivery system for use in an asymmetric network to provide full-duplex communication, said system including a host server and at least one remote client that has a remote link adapter operating in accordance with a high speed downstream and a lower speed upstream protocol, said packet delivery system comprising:
