Bandwidth Control

Optimize the Use of Bandwidth in the Face of Bandwidth-Hungry, Audio-Video Streaming Applications

With the arrival of Web 2.0, audio-video streaming applications have become very popular. It is not just the popularity of YouTube and Hulu¡ªevery major website is incorporating streaming technology to promote its products and services.

Web 2.0 Applications Can Degrade Performance of Critical Business Applications

As bandwidth need has gone up, so has the cost of providing bandwidth for corporations. Many organizations report that annual bandwidth costs have been growing over 30% per year. In a corporation, when a VoIP call is taking place or an online demo is being delivered to the customer, a few sessions of P2P, streaming media started by users unknowingly can degrade performance and quality.

Bandwidth Control Policy

Several policies are applied to conduct bandwidth control, assisting enterprises in building reasonable bandwidth allocation policies. Accelerate critical applications; reshape and optimize Internet traffic; cut down bandwidth cost.

- Protocol-based: provide control based on http, FTP, smtp, POP3 and self-define protocols. Users are free to define guarantee bandwidth, accelerate critcal applications to meet production needs.

- Application-based: offer policy based on application types such as P2P, streaming, URL categories, and specific applications such as BT, eMule. Allow user self-define volume for bandwidth reshaping.

- Time-based: choose bandwidth control policies based on time period. For example, allow larger volume to P2P, streaming use for employees entertainment needs.

- Usergroup-based: choose bandwidth control policies based on user/usergroup/department. Allow respective individual policy for sales department and RD team to realize resonable bandwidth allocation.

- Fair allocation-based: traffic from different users in the same pipe get chance of transportation in turn to realize fair allocation.

- Bandwidth pipe priority allocation: bandwidth objects under the same interface are free to share idle bandwidth after guarantee bandwidth is satisfied. Idle bandwidth is shared in the order of priority level of each object with portion corresponding to the guarantee volume. This process keeps going till all idle bandwidth is used or all bandwidth objects' demands are met.

- Single user-based:limit maximum volume of single user in a bandwidth bus.

- Up-going and down-going traffic-based bandwidth control: define guarantee volume and limit volume to Up-going and down-going traffic.
