Of possible interest to the homenet community, I think:

This disconnect between customer needs and > current practice suggests that we need to revisit how to solve this problem. > > In response to this customer demand, Aerohive, Aruba, Cisco, and Xirrus have > all recently announced "Bonjour gateway" products which allow service > discovery beyond the local link.

Enterprise networks > 2. Academic/Educational/University networks > 3. Multi-link home networks, such as that envisaged by HOMENET* > 4.

Enable discovery of services across multiple links. > > 2. Zero configuration operation possible, but not mandatory. > - i.e. Zero configuration operation is supported by the protocols, > but administrative control is also available on networks where that > is desired. > > 3. Scalability, in terms of: > - Network traffic > - CPU and memory requirements on network entities > - User interface (huge flat list is not user friendly) > - Having a smooth continuum of operation from local link to site to > global, rather than wildly different incompatible modes of > operation at different network scales > - Granularity of services available on a server (extend the notion of > service?) > > 4. Suitable for both local (zero-config) and global (configured) use > - i.e. Suitable out-of-the box defaults should enable zero- > configuration use on many small- to medium-sized networks, while still > allowing for administrative control in networks where that's desired. > > 5. Incremental deployability > - Identify what changes to existing network elements will be > required, and attempt to minimize those changes. > - Don't break existing DNS-SD/mDNS functionality and devices > > A BoF session is tentatively planned for 1520-1650 Tuesday 6th November 2012, > subject there being enough interest to warrant moving ahead to that stage. > > Stuart Cheshire _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
