Websense Enterprise
® Bandwidth Optimizer enables organizations to reduce and optimize network bandwidth resources by allowing prioritization of network traffic. Bandwidth Optimizer (BWO) automatically
manages network traffic in real-time to ensure that business-critical applications are given priority to network resources, including the capability to temporarily disable non-business related traffic as
network usage thresholds reach certain levels. Internet threats pose bandwidth problems
Streaming audio, streaming video and peer-to-peer file sharing are placing increasing demands on network
resources.
Alarming bandwidth statistics:
- More than 72% of Internet users do more than just peruse Web content. Popular Internet activities now include bandwidth-intensive music downloads and video clips.
- 44% of corporate employees use streaming media.
- 74% of weekday Internet radio access takes place between 5am and 5pm.
While some network traffic is easy to classify as non-critical to business, much of it, including streaming media, may be either work-related or non-work-related. Therefore, Internet management policies
that simply block all bandwidth-intensive applications at the corporate firewall may be counter-productive.
The Bandwidth Optimizer solution
Bandwidth Optimizer provides a sophisticated Internet
management system for the allocation of network bandwidth in an enterprise employee computing environment.
BWO enables a network administrator to:
- Set lower network bandwidth thresholds for non-business-related Web sites, such as shopping and entertainment, and higher thresholds for work-related sites.
- Manage network bandwidth allocated to instant messaging sites by setting thresholds that vary by specific users or groups, allowing chatting when ample bandwidth is available.
- Manage network bandwidth allocated to streaming media by blocking bandwidth-intensive streaming media applications when network capacity is limited.
Key features
Flexible filtering options - Set network bandwidth limits by network protocol or Web site category. For example, block new requests for RealPlayerTM
when total network utilization surpasses 75% but continue to allow Windows Media PlayerTM
for the marketing team at any time. Network bandwidth thresholds can also be set for custom protocols and URLs.
Multiple network bandwidth limit types
- Bandwidth Optimizer supports two types of real-time thresholds on protocols and Web page categories:
- Limit-based outbound network traffic
- Denies new requests for bandwidth when total outbound traffic exceeds a pre-defined threshold. For example, allow access to shopping-related Web pages until total network utilization reaches 80% or allow streaming media when total traffic is less than 50% of total bandwidth.
- Limit-based per-application bandwidth usage
- Deny new requests when the total bandwidth being used by a particular network application exceeds a pre-defined threshold. For example, allow employees to use Microsoft® Windows Media
® Player until the bandwidth used by Media Player traffic exceeds 20% of the total Internet connection.
When a network bandwidth limit is reached, Websense Enterpriseautomatically disallows only new requests until bandwidth drops below the required threshold level, allowing business-critical Internet
applications to run at full speed. Existing network connections are unaffected.
User- and time-based policies
- Set different network bandwidth limits by user, group, workstation, network and time of day. For example, during business hours, a company's management team may be given a higher bandwidth threshold than the sales department, however, everyone is allowed full access after 5 pm.
Dynamic policy enforcement
- Websense Enterprise automatically monitors network bandwidth levels and dynamically allows and denies network application requests. No administrative intervention is required.
