Bandwidth Control

Bandwidth ControlOnce limited to recreational usage, today every major web site is incorporating streaming technology to promote its products and services. Many companies have one or more YouTube channels, and deliver streaming webcasts to promote their products and services.


Traditionally bandwidth has been controlled by protocol. For example, a company may define a policy that allocates 10% of its bandwidth for FTP, 60% for HTTP traffic, and 15% for SMTP traffic. Today, over 80% of the Internet-bound traffic from a corporation is HTTP or HTTPS. Allocating 80% of the total bandwidth to HTTP is not helpful if half a dozen streaming applications can consume most of that at the expense of, for example, your Salesforce.com or accounting application.

Control Bandwidth by Application

Zscaler enables organizations to intelligently monitor, allocate and manage bandwidth by providing policy-based bandwidth control based on the application being used. For example, a company might define a policy to allocate at least 20% of the bandwidth for its CRM application and 15% of its bandwidth for online meeting applications such as WebEx.

With Zscaler IT organizations can manage bandwidth usage based on:

  • Application: Tailor bandwidth policy based on applications, such as Salesforce.com or NetSuite. Limit the bandwidth used by social media apps.
  • Time: Create policies to limit use based on time of day; for example, to prevent media downloads, provide only 15% bandwidth to large file transfers between 8am and 5pm.
  • Location: Customize policies by office location; for example, headquarters with a higher number of sales and marketing users might be allocated more streaming bandwidth than a remote office location focused primarily on support.

Zscaler Saves MPLS Bandwidth

Many enterprises backhaul Internet traffic from various locations around the globe to a couple of central gateways at the headquarters, where URL filtering is performed. This is often done by purchasing multi-packet label switching (MPLS) networks. However, backhauling traffic creates latency and costs money. Zscaler’s distributed architecture with dozens of cloud nodes deployed around the globe eliminates the need to backhaul traffic, hence reducing latency and bandwidth costs.
