Abstract
Multicast and broadcast frames transmission rate logic limiting the rate at which multicast or broadcast frames are forwarded by a MAC layer device interconnecting local area networks such as a bridge or switching hub, so as to prevent multicast or broadcast storms from propagating from one local area network to another local area network. Such logic is distributed among a plurality of local area network (LAN) ports of a switching hub, allowing the overall maximum rate at which such frames may be transmitted to be individually tuned on a per LAN port basis. The transmission rate logic includes a burst capability, in which the overall rate to which multicast and broadcast frames may be limited can be exceeded for a finite number of such frames. The burst capability may also be individually tuned on a per LAN port basis.
