This is a Internet traffic manager that helps you work comfortably even when a heavy download is continuing.

Even when your download manager or torrent client is downloading a large files, you should be able to work comfortably with your other activities including Internet surfing. NetBalanacer balances the load effectively by controlling and monitoring data traffic on Windows. NetBalancer is an Internet traffic control and monitoring tool designed for Windows XP/2003/Vista platforms. This tool will let you set download/upload transfer rate priority for any application and monitor their Internet traffic to manage an even balance. Applications with higher priority are allowed more bandwidth compared to the lower priority one. By making it priority based rather than a fixed bandwidth allocation strategy, this application would not starve a lower priority one when a higher priority task has no bandwidth demands.

You would be able to set several levels of priority to ensure load balancing between all the current activities. The priority levels that could be set include High priority, low priority, normal priority, block traffic, ignore traffic and limit traffic. Each network adapter can have its priorities and limits that can be individually managed. The tool supports IPv6 already so that there need not be any worries as to what might happen when the changeover takes place or any compatibility issues. Several traffic measurements help you make sense of what’s going on and tune things (tweak the priorities). Graphic displays help make sense of the situation quite easily. This is quite a useful tool. The Free version is limited to a maximum of 5 process priorities/limits and 5 rules at a time, has no separate network adapters management and no support for Network Grouping though.
