Columbia Developing Large VoIP Systems for Verizon

Work by Columbia University’s Department of Computer Science, funded by Verizon Communications Inc.’s Verizon Laboratories, the research arm of Verizon’s Technology Organization, and under the direction of VoIP pioneer Dr. Henning Schulzrinne, is developing two VoIP network systems designed for very large network deployments.

Schulzrinne tells New Telephony that the first project is “to build and measure a very large-scale VoIP firewall for tens-of-thousands of concurrent calls.”

The second project is to design and prototype a very large presence system with privacy policies. The development of privacy policies enables users to control “what information they want to release and too hom,” says Schulzrinne, “so they can tailor the messages by recipient.”

Schulzrinne says Verizon “certainly seems interested in something where they can roll it out to subscriber bases that are larger than enterprise size or small groups of several thousand customers.”
