Abstract

This article will give a solution to solve the problem on important applications accessing the network when network congestion happen. The solution can promise the higher priority applications get more bandwidth than the lower priority ones which is different from the known solutions, it consists of client and server and uses traffic control on the server side to control the applications.

System and methods of smart enterprise network traffic control

As we all know, network bandwidth is limited for all the companies. In work places, all the applications share the limited bandwidth, network congestion happen frequently, slow network speed, no response for a long time. Those situations impact the efficiency of our work, and even block the work. Hence, how to promise the important application get adequate bandwidth while in network congestion is a big problem.

There are several solutions for individual customers, these solutions limit the speed of networking applications on personal computer and can only be used in one client, it doesn't solve our problem and it is not suitable for enterprise use.

Another solution is described in the US application publication number 2002/0143911 A1 filed on 2002 entitled "Host-based network traffic control system". This patent has three parts, NetTC agent, NetTC administrator and Policy server. NetTC agent is responsible for enforcing the flow control on the data flows generated form the applications running on the client where the NetTC agent resides. NetTC administrator is responsible for centralized Qos provisioning and for remotely controlling the enforcement of flow control on the data flows generated by the host system, via the NetTC agents associated with the clients. Policy server is used to store QoS provisioning policies. This solution is for enterprise use and limit the client's network speed, but it doesn't solve the problem if the flow is in congestion, the higher priority applications get more bandwidth than the lower priority ones, so we give out this solution to resolve the problem we encountered.

This invention provides a solution to manage the network bandwidth which is being shared by various of applications in an enterprise scale. The purpose is to ensure the higher priority applications can be assigned more bandwidth than the lower priority applications in order to promise the daily work normally while the bandwidth is too little to match the requirement of all the applications in an enterprise scale. In this solution, only the upward flow will be managed.

To implement this solution, the traffic control service will be set on the server side, and each application from client sides will be collected and controlled before sending requests to internet. A stand-alone server is required to manage the assignment of bandwidth, according to the priority of each upward request from client sides. Meanwhile, an application is running on each client (laptop or desktop) to add tag into each upward packets to identify the application which send out the upward request . Also, the client will provide a GUI to the individual user to prioritize the applications which are important to this user.

The client will have a small application running on the OS, and it has two key functions below:


1. Provides a GUI console to the user, and allow the user to select different applications t...
