Bandwidth Controller enables you to monitor and limit bandwidth usage on your computer or local network. You can create rules for upload and download activities and limit the bandwidth usage to X bytes/sec with the option to further filter the rule by local or remote IP address. The program also includes a real-time traffic monitor with detailed statistics for each ongoing upload or download. Bandwidth Controller Personal Edition is limited to the TCP protocol.

Bandwidth Controller Standard contains many useful features for home and small office networks. It brings high performance traffic shaping to the desktop in a small, easy to use package. No server or gateway computer is needed as the product is designed for networks with a direct connection to the modem or router.

Prioritization
Give applications a boost using traffic prioritization. This feature delivers maximum throughput for time-sensitive network software including games, VoIP and video.

Speed Limiting
Speed limits allow you to cap the transfer rate for high bandwidth applications such as web downloads, peer-to-peer applications and FTP. Because the product operates at layer 3 in the TCP/IP stack, speed limits are protected from users and cannot be altered or exceeded in any way.

Traffic Monitoring
Internet usage is viewed using the built-in traffic monitor. It displays the amount of bandwidth being used, and the protocol, direction, user, port and traffic statistics.

Bandwidth Controller provides many features for traffic shaping and bandwidth management. The table below lists the features that are found in each edition.

Features and Specifications:

Server-Free Mode Allows automated bandwidth distribution for networks that connect directly to a hardware modem or router, without the need a server or gateway computer.
Speed Limits Sets a maximum transfer rate for users and protocols that are traffic-intensive.
Layer 3 Kernel Processing All network transactions are processed at Layer 3 in the IP stack resulting in the highest possible traffic shaping performance for larger networks.
Traffic Monitor View traffic statistics for internet streams in real time including protocol, speed, transfer totals and graphs for all active connections.
Prioritization Boosts real-time protocols such as VoIP, games and video for extra performance. Priority can also be given to workstations or other applications.
Remote Management Provides access to centralized shaping rules, traffic monitoring and configuration from any client computer.
Protocol Classification Different flow types are processed separately, allowing user-defined Quality of Service and traffic shaping.
Address Groups Allows policies to be set for entire groups of users which can be identified by IP address, MAC address (for DHCP networks) or domain name.
Guaranteed Reservation Service Level Agreements can be quickly implemented using guaranteed minimum speeds for specified users and protocols.
Percentage Allocation Splits bandwidth at a pre-defined ratio between groups of users. For example, one group can be allocated 25% of available bandwidth, and another can be given 75%. The available bandwidth is calculated dynamically and varies according to the internet load.
Deep Packet Inspection Classifies traffic based on Layer 7 stream content, rather than the Layer 3 protocol and ports used. This allows shaping by application such as FTP, HTTP, Video streaming and other high level protocols.
Dynamic / Batch Rules Automatically detects active users and evenly distributes traffic between them. This feature is useful for web servers, for instance, where the IP addresses of the remote machines are not known in advance, allowing traffic shaping with a single rule for a group of users.
