    摘要: An arrangement of trunk clusters and a method for interconnecting trunk clusters wherein the interconnection method has no single point of failure, the bandwidth between trunk clusters is not limited by the throughput of a single switch, and faults are contained within each trunk cluster. A trunked interconnection structure is provided between trunk clusters. Each switch of a trunk cluster has a logical port connected to a trunked port. The trunked port or trunk port provides a physical connection to each trunk switch of another trunk cluster. Each trunk switch of the another trunk cluster has a logical port connected to a trunked port which in turn has physical connections to each switch of the first trunk cluster. Trunked interconnect isolates faults to a single trunk cluster and there is no single point of failure and the total throughput is not limited to any single switches capacity. This always provides a single loop free path from one trunk cluster to the other or others. Multiple trunk clusters may be interconnected using point-to-point connections. A high throughput campus interconnect trunk cluster can be used to connect each building data center trunk cluster.

    摘要: A bridge (62) capable of reducing unwanted WAN multicast packet traffic in a LAN is disclosed. The bridge examines the contents of WAN multicast query and report packets and includes this information in its filtering database (88). The bridge designates ports on which query packets are received as query ports. When there is no WAN router generating multicast query packets into the LAN, the bridge simulates the behavior of a WAN router and generates WAN multicast query packets so as to cause report packet generation by end systems. A timeout interval for undesignating query ports and a method for determining an appropriate timeout for a port is disclosed.
