         C3 is supported by CableLabs ;    
         C3 follows after successful Linux Foundation model ; 
         C3 is a platform for collaborative software development ;
         C3 is scalable to accommodate a large number of projects ;       
         C3 provides a project template charter for anyone to start a new project ;
         Projects can be truly “open” where access is open to anyone ; 
         Projects can also be “closed” where access to code (etc) is restricted ;
         Projects can migrate from C3 to other Open Source and Standards Bodies ;

            PNM tools help operators troubleshoot the network ;
            Network devices measure key diagnostic attributes ;
            Identify and isolate problems before they are customer impacting ;
         case 2:  /* TruView */
            TruView software characterizes cable plant signaling ;

    * We assume that the plain text version of this story is easier for you to read.
    * The relevance of collaborative software development, including open source and  
    * community-source approaches, for the cable industry cannot be overestimated. 
    * Increasingly, collaboratively developed software is being deployed in cable  
    * products and services. And, the development tools that the industry uses to build  
    * those products and services often leverage open source implementations. The RDK  
    * is just one example that demonstrates the robust and powerful approach of sourcing  
    * the software development across an open or semi-open community (i.e. community  
    * source group) for the cable industry.  Other cross-industry organizations where 
    * the cable industry participates include the Open Platform for Network Function 
    * Virtualization  and the OpenDaylight Platform.  
    * So, what’s missing for the cable industry?  
    * ANSWER:  A platform where the cable industry (and beyond) can collectively  
    * collaborate around the development of tools and software assets relevant, 
    * but not limited, to cable.  
    * At its Winter Conference 2016, CableLabs announced the launch of the 
    * Common Code Community (C3) platform, including essential elements such as IT 
    * infrastructure, development tools, repositories, access control, recommended  
    * best practices, modular licensing, and outreach to other communities and standards. 
    * As of today, the C3 project hosts three projects:
    * 1.  OpenRPD – A software reference implementation supporting the Remote PHY
    *     Device architecture – a virtualization architectures used in distributed
    *     CCAP implementations.  Seeded with software developed and contributed by 
    *     Cisco, the project drives core router and remote PHY interoperability.
    * 2.  Proactive Network Maintenance (PNM) – A set of tools that reduce troubleshooting
    *     and problem resolution time by detecting and localizing network problems 
    *     before they impact the customer.   
    * 3.  TruView - Software seeded by Comcast and extended by CableLabs as a set 
    *     of tools to assist cable operators in the successful deployment of 2-way 
    *     infrastructure used to load and initialize settop boxes
    * Each project defines its own governance structure such as who is allowed 
    * to commit code, submit code, launch builds, define new code releases, and so on.
    * The C3 platform also provides a flexible license model where each project sets 
    * the licensing and IPR structures most appropriate for its goals and assets.
