In accordance with aspects of the present principles, the quality of voice traffic and bandwidth utilization for data communication over a wireless multi-hop network may be improved. In an implementation of the present principles, a data packet transmission rate over a wireless multi-hop network may be controlled at an interface between the multi-hop network and a wired network based on a voice packet quality measure calculated from network parameters. Voice and data traffic quality and efficiency may be further improved by reordering a packet transmission queue at the interface to avoid timeout and/or varying a packet queue length at the interface using an acknowledgement window transmitted to a data packet sender.

The invention discloses an automatic repeat request (ARQ) window management method which is characterized in that receiving terminals of layer entity are controlled by use of wireless links of confirmation mode; and when the sections of the wireless link control protocol data cell corresponding to the lower boundary of the currently-received window or all the wireless link control protocol data cells are not received successfully and the preset conditions are met, the receiving window are triggered to move continuously. The ARQ window management method overcomes the problems of wireless resource waste and unfairness when the service data unit (SDU) is discarded, and avoids the complexity of sending the move receiving window (Send MRW).

Re-synchronization of sets of transmit and receive state variables in a communication system is achieved when an error is detected, without disrupting the connection. Each of first and second transceivers, connected by a communications channel, have a common set of transmit and receive state variables supporting a data encoding algorithm function. The transmitter of one of the first and second transceivers fist encodes data to be transmitted and updates the transmit state variables according to the data encoding algorithm and the receiver of the receiving transceiver validates whether or not each data block has been received correctly. During the process of decoding the data, the receive state variables are updated according to the same algorithm used to update the transmit state variables, thereby keeping the two sets of state variables in synchronism with each other. When an error is detected, re-synchronization occurs by switching to transparent mode in the direction of communication in which the error occurred and resetting the corresponding transmit and receive sets of state variables.

A method and system for preventing a timeout from reaching a network host when bringing up a down link that is slow to waken. The method generally comprises receiving a request to access an information. If a link along a path to a remote computer containing the information is down, the link is established while concurrently returning a plurality of imposter responses, such as domain names, until the network link is established. Software implementing this method may be stored and executed in any network host. This method is particularly advantageous when waiting for a dial-up telephone connection to a network to be established.

A method and system for providing access control to networked resources is provided. Optimally, the system comprises at least one networked resource coupled to the internet via a gateway having a ‘private’ or ‘internal’ side coupled to an intranet, and a ‘public’ or ‘external’ side coupled to the internet, and the gateway controls access to the resource. An access controller is coupled to the external side of the gateway, i.e. outside the intranet. Upon access request by an access requester, the gateway communicates the request to the access controller. The access controller utilizes the requested URL to select a login applet that is communicated to the requester. When the requester returns the login information, the access controller authenticates the user and generates an access management applet specific to the user. The access management applet controls access to the networked resources in conjunction with code on the gateway. Additional optional features include auditing and the capacity to provide access to several organizations using a single login.

Rapid and reliable network data delivery uses state sharing to combine multiple flows into one meta-flow at an intermediate network stack meta-layer, or shim layer. Copies of all packets of the meta-flow are buffered using a common wait queue having an associated retransmit timer, or set of timers. The timers may have fixed or dynamic timeout values. The meta-flow may combine multiple distinct data flows to multiple distinct destinations and/or from multiple distinct sources. In some cases, only a subset of all packets of the meta-flow are buffered.
