A METHOD OF INCREASING THE EFFICIENCY OF UTILISATION OF BANDWIDTH IN A NETWORK

Abstract

The invention proposes a new method to utilize the network bandwidth in an efficient manner especially when the web client is browsing a web page along with its associated contents like images, scripts and styles. The new method proposed in the invention formulates a way to considerably reduce the possible transactions between the client and the proxy gateway in order to reduce the protocol overheads and network congestion caused by the transactions. The ultimate goal of this invention is to enable optimized access to applications and services from the current and emerging generations of web services that are sensitive to limited bandwidth requirements.

WE CLAIM 1. A method of increasing the efficiency of utilization of bandwidth in a network while browsing the web, wherein both the client and proxy gateway negotiate on the new system before making any transactions to the web document in that the client sends a request to a web document by including the CPI information of the system and the proxy gateway, in turn, sends a consolidated response over the network after receiving the associated contents from the origin server. 2. A method as claimed in claim 1, wherein the protocol overheads and network congestions, are alleviated and better quality of service is achieved in that the number of transactions is significantly reduced, as the proxy gateway consolidates the responses into a multipart object. 3. A method as claimed in the preceding claims, wherein the client directs the proxy gateway to initiate subsequent requests for associated contents like scripts, styles and images to be loaded along with web document thereby reducing the request & response chains between the client and the proxy gateway. 4. A method as claimed in claim 1, wherein the network is a low bandwidth network. 5. A method as claimed in claim 1, wherein the system works under persistent connections to improve the efficient usage of network and in non-persistent connections to provide a similar persistent behaviour at the application level. 6. The method as claimed in the preceding claims wherein optimized access to applications and services from the current and emerging generations of web services is enabled. WE CLAIM 1) An adaptive scheduling method for efficient resource allocation in WLAN in PCF mode comprising the steps of: (a) deciding the order in which to poll the mobile node; (b) deciding which node to poll at the given time; (c) sending the polling message and data to the node in the forward direction; and (d) sending an acknowledgement and data to the WLAN-AP by the mobile station on successful receipt of the packet. 2) A method as claimed in claim 1 wherein the said method involves WLAN-AP communicating with the 3G-BTS and two wireless hops. 3) A method as claimed in claim 1 wherein the said method of scheduling involves efficient resource allocation over the WLAN air interface to satisfy the QoS requirements of heterogeneous applications wherein to allow network operator to offer different types of fairness criteria and service level agreements to WLAN users for the forward and reverse link flows in the PCF mode of a WLAN network and wherein to compensate applications having QoS requirements specified by some of the parameters such as delay bound, delay jitter, average delay, throughput, and packet loss for flows in both the forward as well as reverse directions, flows are separated into forward link flows from the AP to MS and reverse link flows from MS to AP ; the flows consist of MAC layer packets; each MS has multiple flows with different traffic requirements in both directions; for each forward link flow to an MS, the AP maintains a queue of MAC layer packets and for each reverse link flow an MS maintains a queue of MAC layer packets; the scheduler is located at the WLAN access point but does scheduling for forward as well as reverse link flows; packets corresponding to forward as well as reverse link flows at the WLAN-AP are monitored and their rate and delay violation statistics are calculated and to compensate flows that are not getting their required QoS guarantees the QoS compensation metric Mk[Tn]for each flow k at each time t„ is
