  • Rate enforcement for frame relay networks
    Patent number: 5412647
    Abstract: A Frame Relay network must implement a rate (bandwidth) enforcement function at the access in the network so that service subscription violation by some users will not cause performance or throughput degradation of other users' service. A novel rate enforcement technique is disclosed. The new technique makes use of a "leaky bucket" algorithm in which a portion of one "leaky bucket" is set aside for high priority frames only.
