ET/BWMGR - Bandwidth Manager

Powerful enough for Large ISPs, cost effective for small corporate networks

Emerging Technologies' Bandwidth Manager is a full-featured traffic management tool that gives you control of your network traffic, increasing the efficiency of your network and reducing your overall bandwidth requirements. If you've been thinking that you need more bandwidth, or just that your traffic patterns are out of control, you should consider a bandwidth management product. The ET/BWMGR is available as a standalone appliance which plugs into your existing network, or as a software appliance that you can build on your own hardware from our CD.

Market Leaders

Emerging Technologies was the first to introduce full gigabit bandwidth managment and with 10 years of rock-solid performance, we continue to lead the market in price/performance by a wide margin. Most users of this product are Internet Service Providers and Universities with very heavily loaded networks, and the ET/BWMGR handles the heat like no other product can. Don't be fooled by the fancy marketing jargon used by our competitors. While our competitor's may offer a few extra bells and whistles, the core functionality of our product addresses the most pressing needs of Bandwidth Management. The bottom line is that the ET/BWMGR can give you the same rich feature set found in competitive products for a fraction of what our competitors are charging. How, do you ask? The reason is simple: We have leveraged the availability of off-the-shelf hardware and popular free operating systems to reduce our overhead. The result is that, while our competitors have teams of engineers debugging and developing hardware platforms (which is a function of their pricing), we can focus on the core software technologies and offer them to you at a much lower price.

Hardware Failover

We are now making our hardware failover card available for use with the software version of the ET/BWMGR. Hardware failover allows you to take the system offline remotely when doing maintenance, and also will allow your traffic to flow "through" the bandwidth management system in case of failure or while rebooting. If you can't afford to be down, or if you don't have 24/7 coverage, its a must-have add-on for the bandwidth management software.

Features:

Following are some of the more noteworthy features of the ET/BWMGR.

HTML Management Interface (GUI)
Bi-directional Bandwidth Limiting and Allocation
Multi-port Bandwidth Managment at full gigabit speeds
Unlimited Sessions or Policies (limited by CPU power only)

Integrated Firewall Function
Compression (FreeBSD only)
Multi-Speed Bridging on Any Number of Ethernet Interfaces (ie bridge gigabit to multiple 100Mb/s)
Support for Hardware Failover Card (eliminates single point of failure concerns)
Manage Traffic by IP, MAC or Network Address or Protocol
p2p Traffic Control (KaZaA, Morpheus, iMesh, AudioGalaxy, etc)

Allow your Customers to View Graphs of their Traffic
Statistics-only mode ("sniffs" your LAN and gathers stats without being inline)
Export Statistics via SNMP for any data type
Graphing of any definable address, network or traffic type with Daily, Weekly and Monthy Usage Reports
Graphing of external Routers and Devices with integrated SNMP Client (MRTG Replacement).

The ET/BWMGR includes all of the features that you would expect with the highest-end products available including a graphical interface, full-featured bandwidth management, statistical reporting, multi-level prioritization of traffic and much, much more.

Multi-Port Transparent Bridging

ET/BWMGR runs as a high-performance transparent bridge on multiple NICs, allowing it to operate as a multiport, multispeed switch. The ET/BWMGR includes advanced bridge group capabilities that allow unlimited groups to be set up to facilitate any numbering scheme you need.

The BurstManager

The ET/BWMGR has a burst management feature that allows you to grant additional bandwidth on a policy by policy basis based on overall traffic on your network. For example, you you can limit a particular IP or range of addresses to 512000bps when usage is below a defined threshold and 128000bps when usage is heavy. Burst thresholds can be flexibly applied, for example if you have a "premium" group of customers, other groups can be set to only burst when the premium group is using less that a specified amount of bandwidth. Bursting can be limited to a specific length of time, easily thwarting downloaders while providing snappy performance for browsing.

10 levels of Data Prioritization

The ET/BWMGR allows you to set 10 levels of priorities for traffic, and with multiple class grouping options you can do just about anything you want to do to manage your traffic. Prioritization along with "to the bit" bandwidth limiting allows you to allocate, limit, burst, prioritize and guarantee bandwidth with precision.

Corporate Streamlining

Not only ISPs can benefit from bandwidth management. Companies need to make sure that their critical traffic streams flow smoothly, and that database response times meet service level requirements. Imagine if you could dynamically allocate bandwidth for a critical download? Its easy with the ET/BWMGR.

Advanced Rule Indexing Increases Capacity

The ET/BWMGR implements a rule indexing technique that decreases overhead by up to 96% over linear scanning algorithms. Our powerful technology allows ET/BWMGR to manage literally thousands of individual streams and classes of traffic with hardly any rule matching overhead. As far as we know, ET/BWMGR can handle more simultaneous user-defined traffic streams than any other product on the market, and is the only product that can handle complete rulesets at gigabit speeds.

Customer Feedback

You can grant your customers access to the graphical output pages on ET/BWMGR by simply creating a simple access page for them. Your customers can view statistics and graphical analysis any time they want and for any period of time that is stored on the machine.
