Introduction: William T. Haggerty, an esteemed inventor based in Dunstable, MA, has significantly impacted the field of communications technology. With a portfolio that includes seven patents, his work reflects a deep understanding of networking systems and data management. Haggerty’s latest inventions demonstrate his commitment to enhancing efficiency in communication networks.

Latest Patents: Among Haggerty's most recent contributions are two key patents. The first is centered on the **aggregation of data flows over a pre-established path to reduce connections**. This method and apparatus improve connection-oriented switching in communications networks by establishing a predefined path between an ingress switch and an egress switch. By employing these pre-established paths, Haggerty’s innovation reduces the total number of connections within the switch cloud, lessens CPU load on trunk switches, and accelerates connection setup time. The design incorporates a “virtual path” that replaces traditional MAC frame data packet fields, streamlining the communication process significantly.

The second patent addresses **multicast switching**, providing a method for establishing connections in switch-based communications networks specifically for multicast traffic. This innovation allows a source to determine a group address from a multicast packet and effectively communicate with other switches in the network. Haggerty's method enhances the establishment of a connection path that allows multiple receivers to connect seamlessly to a sender, simultaneously improving controlled multicast traffic across various network interfaces.

Career Highlights: Haggerty’s career includes notable positions at leading technology companies. He has worked with **Cabletron Systems, Inc.** and **Enterasys Networks, Inc.**, where he contributed his expertise to advance communication technologies. His experience at these companies has enabled him to innovate and design solutions that address complex challenges in network connectivity.
