Much of the Named Data Networking (NDN) project codebase is still at the Version zero-dot-something level. But things are nevertheless starting to get real for this content-centric architecture designed to blast past today’s host-based and point-to-point Internet scheme to one more suited for accessing applications across hugely scalable networks that are mobile and extend to all sorts of sensor-equipped things.
The NDN project team hosted more than 100 people from 63 institutions and 13 countries at UCLA last week to share progress and ideas at the second annual NDN Community Meeting (the first such meeting that we wrote about a year ago in "UCLA, Cisco & more join forces to replace TCP/IP" drew attendees from 39 institutions and 7 countries). A quick search of the IEEE digital library through early October turned up 42 papers from 2015 with Named Data Networking in their titles, whereas there were 52 new Named Data Networking papers for the entire span of 2014.
In addition to academic experts, influential network and computing vendors such as Cisco, Alcatel-Lucent, Huawei and Intel are behind this movement and took part in NDNComm, which featured sessions on topics such as advanced routing -- “hyperbolic” no less -- serious science applications and trust/security/encryption.
That meeting was immediately followed, up the coast in San Francisco, by the 2nd ACM Conference on Information-Centric Networking, where NDN was one of the stars. And prior to all this, UCLA hosted the first NDN hackathon.
NDN's spiritual leader, Internet Hall of Famer and UCLA adjunct professor in computer science Van Jacobson, delivered keynote addresses at both NDNComm and the ACM event. NDN has its roots in content-centric networking, a concept that Jacobson started discussing publicly about 10 years ago while at Xerox PARC.
Jacobson actually took the podium at NDNComm after Jeff Burke from UCLA’s School of Theater, Film and Television. Burke set the stage by focusing on how researchers in the arts and beyond are intensely interested in where the Internet is going as a means for communicating stories, and not just as in movie plots, but in the broader sense of the stories of our lives (think personal health, and tapping into everything from genome to Fitbit data). Named-based data could be a godsend for exploiting Big Data, including information served up by a sensor-based Internet of Things, and for supporting emerging applications, such as video streaming like you’ve never seen before, he said. “[NDN can] take us far beyond the connection-oriented model that a lot of our applications started in,” Burke said, adding that people should be excited about “the opportunities to be designing for applications that are coming
