PARC Offers Content-Centric Networking (CCNx) Software to Advance Next-Generation Internet

Press Release

Palo Alto, California — PARC, a Xerox company, today announced that its Content-Centric Networking (CCNx) software is now available under the PARC Software License. Companies and developers can now download CCNx source code at no charge. PARC’s CCNx software can be downloaded at

PARC is continuing its legacy in networking with the creation and development of CCNx. Designed to model the way the network already works, CCNx addresses the problems facing the Internet today, including seamless content distribution, mobility, security, and scalability. PARC is well known for inventing networking technologies, including Ethernet, PUP, and XNS, as well as significant contributions to IPv6 and Internet multicast.

“We deeply appreciate our supporters, collaborators, and early adopters who have helped and encouraged us in studying CCNx and developing content-centric methods and solutions. We are very happy to make our software implementation available to all kinds of developers,” said Glenn Scott, PARC’s Area Manager for Networking Architectures and CCNx’s Principal Investigator. “We’re all seeing how sluggish the network can be, and with millions more connected devices expected to access the network, in particular through the upcoming roll out of 5G, it will only get slower. Additionally, security must be solved at the content level, rather than the end points. We hope today’s announcement will encourage developers to work with CCNx to promote wider acceptance of a content-centric approach.”

The Internet was originally designed as an end-to-end communications network, but has become a content distribution network for content sharing. The Internet architecture leads to many problems as we adapt an infrastructure optimized for point-to-point communication to handle the exponential flood of digital media, with more and more video programs being consumed on laptops and mobile devices. CCNx enables people to ask for content by name (rather than arbitrary address), finding it from the nearest location (rather than pipes carrying it), and ensuring greater security (by securing the actual content, not the pipes carrying it).

“The Internet of Things is only going to stress the Internet more, as tons of data starts to be collected and shared across the network,” said Teresa Lunt, PARC Vice President and Director of the Computing Science Laboratory. “Companies of all kinds need to consider how the network will handle the massive amount of information that will be collected and shared on an hourly basis.”
