(see http://www.ccnx.org/releases/ccnx-0.6.1/NEWS)

Things in progress

• Transient repo storage

• Refactored ‘sync’ (decoupled from repo)

• Apps: Medical device interface, serverless XMPP, automatic photo sharing

On the radar

• Opportunistic caching support

• CDN-quality transaction logging framework

• Generic link level encap with hybrid ARQ

Community development• Many exciting things happening. E.g.,

‣NDN ospf-n, python bindings, device control & video streaming apps, ns3 simulator

‣ANR-Connect simulator, QoS framework

‣U. Basel CCN-lite

‣ ...

• PARC interested in setting up a clearinghouse to promote & connect these efforts.

Commercialization• Operator and vendor research interest.

• ENC (Emerging Networks Consortium) looking at scenarios and use cases.

• Need people solving real problems to evolve from ‘research’ to ‘advanced development’ stage.

• Eventually standardize based on ‘rough consensus and running code’ (the world may not need another 3GPP IMS)
