BBN was acquired by GTE in 1997 and BBN's ISP division BBN Planet was joined with GTE's national fiber network to became GTE Internetworking, "powered by BBN". When GTE and Bell Atlantic merged to become Verizon in 2000, the ISP portion of BBN was included in assets spun off as Genuity. In March 2004, Verizon sold BBN to a group of private investors. In September 2009 Raytheon entered into an agreement to acquire BBN
Following the acquisition, BBN Technologies will become part of Raytheon Network Centric Systems.
I had not been to the BBN web site in quite some time ; upon browsing, they have some pretty amazing research projects listed:
- Flexible Intra-autonomous-system Routing Environment
- Smart Environment for Network Control, Monitoring and Management
- Density-and Asymmetry-aware wireless Networking
- Proprietary waveforms for wireless networks
- Terabit router traffic engineering
Network World has a very nice article (back in May) on DARPA military research projects. Check this one out (from the Network World article):
DARPA's Quantum Entanglement Science and Technology (QuEST) program is creating new quantum information science technologies, focusing on loss of information due to quantum decoherence, limited communication distance due to signal attenuation, protocols, and larger numbers of quantum bits (Qubits) and their entanglement. Key among the program's challenges is integrating improved single- and entangled-photon and electron sources and detectors into quantum computation and communication networks. Defense applications include highly secure communications, algorithms for optimization in logistics, highly precise measurements of time and position on the earth and in space, and new image and signal processing methods for target tracking.
