NDIS (Network Driver Interface Standard)-based method and system

Abstract

The invention discloses an NDIS (Network Driver Interface Standard)-based method and system. The method comprises the following steps of: configuring parameter data and storing the parameter data to a shared storage module, wherein the parameter data comprises customized access rules; intercepting packet data sent from a protocol driver layer to a miniport driver layer or from the miniport driver layer to the protocol driver layer; analyzing the intercepted packet data and determining that the data carried in the packet data is in accordance with access rules stored in the shared storage module; and processing the intercepted packet data by redirecting or content filtering. According to the NDIS-based redirecting / content filtering method and system provided by the invention, because layer-upon-layer overlaying of an application layer is not needed when redirecting and content filtering processing are executed, the system expenses is reduced, and the response speed and the redirecting efficiency are increased, and the reliability of executing redirecting and content filtering based on the configured parameter data is higher.

Description

technical field [0001] The invention relates to a network driver interface standard technology (NDIS, Network Driver Interface Specification), in particular to an NDIS-based method and system. Background technique [0002] When a network user visits a website through a browser, he often notices that the address of the opened web page is not consistent with the address originally entered, that is, redirection. Uniform Resource Locator (URL, Uniform Resource Locator) redirection means that if the website has a "regular URL" and "alias URL", when the user enters the "alias URL", it needs to be redirected to the "regular URL" to access the same URL; or after the website has updated the domain name, after the user enters the old domain name, redirect the old domain name to the new domain name. Simply put, URL redirection is the process of first taking an incoming URL request and then modifying it to another URL that the website can handle. For example, if the URL coming in thro...

Problems solved by technology

However, it is difficult to customize configuration information and set access rules on the application layer, so it cannot meet the user's business requirements for filtering sensitive information and other content

In addition, the current URL redirection is performed at the application layer, which consumes a lot of system resources, causes slow system response, and cannot handle large concurrent accesses in a timely manner.
