Deploy360@IETF98, Day 3: IPv6, IoT & DTLS

Wednesday at IETF 98 in Chicago features a mix of IPv6, the Internet-of-Things and TLS-related working groups. Each day we’re bringing you blog posts pointing out what Deploy360 will be focusing on.

The morning session offers a choice between the 6LO and PERC Working Groups. 6LO focuses on facilitating IPv6 connectivity over node networks with limited power, memory and processing resources, and has a busy agenda with three drafts related to Neighbour Discovery on IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs), one on running IPv6 over Bluetooth Low Energy Mesh Networks , one on the use of IPv6 in Near Field Communication, one on transmitting IPv6 over electrical power lines, and another two drafts dealing with packet fragmentation and expiration issues. Another draft describes the use cases for IPv6 over constrained node networks and describes practical deployment scenarios.

We don’t normally cover PERC which is working on privacy for RTP conferencing, but this session will be discussing a couple of drafts related to DTLS tunnelling and an extension to the DTLS and TLS protocols to support SDP.

NOTE: If you are unable to attend IETF 98 in person, there are multiple ways to participate remotely.

In the afternoon, it’s V6OPS which just has the three drafts primarily up for discussion. Requirements for IPv6 routers aims to learn the lessons of operating large scale networks on IPv4, Basic requirements for IPv6 Customer Edge routers focuses on some baseline requirements for provisioning these classes of routers, and there’s a draft dealing with the scenario whereby different IPv6 implementations have limited support for SLAAC and/or DHCPv6, and recommends that all hosts implement RFC 6105 (DNS options for SLAAC) and the stateless DHCPv6 functionality in RFC 3315. There may also be an update on Happy Eyeballs that aims to reduce user-visible delays on dual-stack networks, and on Provisioning Domains (PvDs) that allows hosts to retrieve configuration information for accessing the Internet.

Running at same time is LPWAN that’s working on enabling IPv6 connectivity with very low wireless transmission rates between battery-powered devices spread across multiple kilometres. There are five drafts under discussion, but there will also be an update on the IEEE 802.15.LPWA Interest Group activities, as well as a discussion on future work items.

Concluding the day from 15.30 CDT/UTC-6 onwards is the regular IETF Operations, Administration, and Technical Plenary session.
