Abstract

An information communication routing system and method for dynamically determining and utilizing available communication bandwidth is presented. Free excess bandwidth on a scheduled link is measured dynamically and free available bandwidth is dynamically distributed to a queue. In one embodiment, a bandwidth availability tracking value is utilized to measure free excess bandwidth on a scheduled link and the free excess bandwidth dynamically distributed or assigned to a queue. A first packet size (e.g., fixed packet size) is added to the bandwidth availability tracking value whenever a link is scheduled in a calendar scheduling slot. A second packet size (e.g., actual size of the packet departed) is subtracted from the bandwidth tracking value whenever information is departed from a queue. If the bandwidth tracking value exceeds a threshold value (e.g., is positive) it indicates there is excess available bandwidth and the excess available bandwidth is assigned to a queue.
