In one embodiment, a code server and edit server are provided. The code server stores the source code. Users do not access the code server directly. Rather, an edit server is used where users can log in to the edit server and send requests to edit portions of the source code. The edit server then sends requests to the code server for requested portions of the source code. Different users may have different access-rights to portions of the code. When the request is received from the edit server, if the code server determines the user requesting the portion of the source code does not have access rights to it, then the code server does not allow the portion of code to be accessed. However, if the user does have access rights, then the portion of the source code is retrieved and sent to the edit server. The user can then edit the source code on the edit server.

Filtering access to data objects

An asymmetric network system manages bandwidth allocation and configuration of remote devices in a broadband network. A modular architecture of the system permits independent scalability of upstream and downstream capacity separately for each of the upstream and downstream physical paths. Allocation of downstream bandwidth to requesting devices is made according to bandwidth utilization by other devices, bandwidth demand by the requesting remote device, class or grade of service by the requesting remote device or bandwidth guaranteed to other remote devices. Configuration parameters remotely managed by the network include device addresses (global and local), transmission credit values, upstream channel assignment and upstream transmit power level. Further, management of device configuration profiles and bandwidth allocation occurs through control and response packets respectively generated by the network and the remote devices according to network operating software located at both ends. Control packets include poll packets that request, among other things, demand for an upstream transmission. Configuration packets instruct remote devices to assume an operational state or return status or statistical data. Response packets transmitted by the remote devices provide information to the network operations center for control purposes or to confirm the state of operation of remote devices, including channel operating statistics, errors, noise, etc. in order to remove or reallocate assigned upstream channels. Downloadable network operating software enables the network operator to upgrade remote operating software or to reconfigure the response profile of the remote devices. Account administration and usage reports are also generated. IP or ATM encapsulation, as well as forward error correction and encryption, are employed in the broadband network which may include an RF, satellite and cable medium with or without a telephony or router return path.

High-speed internet access system

A hybrid access system and method using a hybrid access system point of presence router and a remote link adapter to connect a user computer terminal to a network for fast downstream information transfer by high speed information broadcasting with lower speed upstream information transfer through an independent upstream channel to the hybrid access system point of presence router. High speed downstream information transfer passes through a cable TV headend or a TV transmitter or a cell station.

Hybrid access system employing data acknowledgement suppression

An asymmetric network system manages bandwidth allocation and configuration of remote devices in a broadband network. A modular architecture of the system permits independent scalability of upstream and downstream capacity separately for each of the upstream and downstream physical paths. Allocation of downstream bandwidth to requesting devices is made according to bandwidth utilization by other devices, bandwidth demand by the requesting remote device, class or grade of service by the requesting remote device or bandwidth guaranteed to other remote devices.

Hybrid access system with remote device monitoring scheme

An asymmetric network communication system for use in a client-host 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 asymmetric communication between the host and plural client devices in a way to pre-authorize the amount of upstream data sent by a remote client.

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. The network manager switches upstream channel assignment based on quality of signals transmitted to the host. The system effects changes in the upstream transmitted power based on sensed conditions.

The network manager switches upstream channel assignment based on quality of signals transmitted to the host, effects changes in the upstream transmitted power based on sensed conditions, and automatically configures new client devices as they are added to the network. The system issues data transmission credits to client devices for enabling them to independently transmit data without supervision up to their allowed credit limit thereby reducing polling for channel allocation requests.
