PacketHop's Technology Heritage
PacketHop's history begins with SRI International. SRI, based in Menlo Park, California, has a long history of innovation and several of SRI's breakthrough technologies are at the heart of PacketHop's mobile-mesh and video networking solutions. PacketHop is continuing to build on the foundation laid by SRI beginning in the 1960s to deliver exciting new products and technologies that improve communications and security using wireless mobile-mesh networks and applications.
1969: ARPANET and Network Information Center
SRI was one of the first four nodes and the recipient of the first log-on on this small network that developed into the Internet. For more than two decades, SRI served as the registration clearinghouse and support center for all computer hosts connecting to the ARPANET/Internet.
The 1970s: TCP Protocol on Wireless Networks
In 1977, in what is regarded by many as the first true Internet communication, SRI sent the first inter-network transmission between three networks, from its mobile packet radio net van in Menlo Park, California, to a host computer at the University of Southern California by way of London, England. The 1970's also saw the first area-coverage data transmission network for use in mobile digital radio serving as the precursor to today's wireless local-area and wide-area networks.
The 1990s: InCON and GloMo
The 90s saw the development of the InCON system that combines intelligence gathering and planning tools to allow field commanders to assess a situation in real time, plot a course of action, direct resources, and evaluate response effectiveness - even when connectivity and operability may be inconsistent. SRI carried out system engineering and integration for DARPA's Global Mobile Information Systems (GloMo) program, working on mobile-mesh networking on a broad front of technologies that included the development of radios and antennas.
The New Century: ReDDE and TBRPF
SRI's Reliable Data Distribution Engine (ReDDE) is successfully deployed on mission critical military and civilian applications. It is at the heart of SRI's family of products for situation awareness and command and control and enables a wired-like experience over less reliable wireless networks. It was deployed with the U.S. Marine Corps in support of the Urban Warrior Program.
PacketHop
PacketHop continues to pioneer revolutionary peer-to-peer wireless technology known as Topology Broadcast Based on Reverse-Path Forwarding (TBRPF) that creates scalable ad hoc networks for ubiquitous mobile broadband access, with no infrastructure needed. This directly leverages SRI's first wireless Internet demonstration in the 1970s and is being applied to a variety of new use cases today.
