2012 Political Conventions Turned to Cable for Telecom Services

For the national political conventions this year, cable was heavily involved with the telecommunications systems.

The IETF and an Evolving Internet

Last week, the Internet Engineering Task Force (i.e. the “IETF”) held their meeting in Beijing, China.  The IETF’s mission is “to make the Internet work better by producing high quality, relevant technical documents that influence the way people design, use, and manage the Internet.”   As the Internet is global, the IETF meets three times a […]
