Abstract
AbstractThis paper introduces a net‐centric architecture based on ETSI and TIA Regenerative Satellite Mesh‐A (RSM‐A) standard that uses satellites with on‐board packet switching. An Internet Engineering Task Force (IETF) IP protocol family‐based extension of RSM‐A for enhanced user interoperability, combined with multiple spot beam satellite implementation facilitates higher capacity, easy deployment and full mesh terminal‐to‐terminal operation that is required for managing emergency situations. This Net‐centric Satellite Mesh (NSM) architecture adequately addresses the current and evolving networking needs for emergency‐management information systems that can generate high data rate and real‐time multi‐media traffic. The NSM architecture supports the evolving IETF Emergency Telecommunications Service standards with packet flow‐level admission control for guaranteed packet quality‐of‐service needed by real‐time unicast and multicast traffic over satellite networks. The multi‐plane architectural discussion is supported with measurements of selected end‐to‐end application behavior that validate the technical capabilities of NSM by using a pioneering Ka band satellite system, based on RSM‐A, which has recently been deployed in North America.
