SLRRP BoF 62nd IETF Scott Barvick [email protected] Marshall Rose [email protected] Welcome! • Simple Lightweight RFID Reader Protocol BoF – Proposal to bring IP network-based RFID operations into the IETF family for standardization – NOT a proposal to do RF standards or high level APIs – just IP network scope – Discussion of proposed work items and Working Group agenda • Agenda includes presentations from RFID and networking companies Slide 2 Agenda • • • • Welcome Agenda Bashing Status Update (I-D, [email protected] list, etc) (5 min to here) Technical Presentations (60 min) – Architecture - P. Krishna, Reva Systems – Tags - Todd Humes, Impinj – Readers - Margaret Wasserman, ThingMagic – Dense Reader Considerations – Kevin Powell, Symbol – Network Operations - Josh Littlefield, Cisco • Discussion (context is proposed Working Group charter) (50 min) • Next Steps (5 min) Slide 3 Status Update • Started WG exploration process in Oct ’04 with goal to standardize RFID infrastructure operations based on open, scalable networking principles. • Engaged IETF ADs as well as representatives from other standards bodies to find appropriate scope. • Established open, IETF-hosted mailing list in Nov ‘04 – currently 110+ members – good mix of RFID, networking, applications, and research companies • ’01 version of initial I-D published containing updates and the results of feedback on ’00 draft, but it is still just the opening brain dump to get discussions going! Slide 4 <Presentations> • P. Krishna, Reva Systems – Architecture Perspective • Todd Humes, Impinj – Tag Perspective • Margaret Wasserman, ThingMagic – Reader Perspective • Kevin Powell, Symbol/Matrics – Dense Reader Considerations • Josh Littlefield, Cisco – Operations Perspective Slide 5 Discussion 1. Potential Work Items 2. Working Group Charter Strawman 3. Related Efforts Slide 6 Potential Work Items • Tag data access and operations (IDs, user data, writing, killing, locking, etc) • Dense reader control capability • Support for multiple air protocols from different standards bodies (initial framework with plugin details) • Security/Authentication based on reader capabilities • Reader Device Discovery and Configuration (DHCP options, profiles, SLP?) • Reader Device Management (MIB) Slide 7 IETF SLRRP Working Group Proposal • Define and document the scope (e.g. problems and solution spaces) – Propose within protocol spec (single deliverable) • Define the Network-Side Communications Mechanism – Simple Lightweight RFID Reader Protocol (SLRRP) is possible base for solution, other forms possible – Solutions to defined data access and control problems • Network Maturity Requirements (after protocol) – Scalable Operations (dynamic configuration, service discovery) – Enhanced Security (base security in initial protocol spec) – Management Slide 8 Related Efforts • ISO – Produces RFID air protocol and data specs – Data Access formats and interface specs (ISO 15961, 15962) for ISO protocols only – No networking specification for interfaces • EPCGlobal – 1+ year old consortium of users and vendors (spun from MIT Auto-ID center) – Produced ‘Gen2’ air protocol specification, submitted to ISO – Producing web-service style interface specifications at all levels of architecture including reader level (“Reader Protocol and Reader Management”). – RP/RM goals based on autonomous reader operation. SLRRP goals focus on network infrastructure requirements of large scale, interoperable deployments across air protocols; related efforts do not target nor meet those goals Slide 9
