  2. 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

  3. Agenda Welcome Agenda Bashing Status Update (I-D, rfid@ietf.org 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)

  4. 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!

  5. <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

  6. Discussion • Potential Work Items • Working Group Charter Strawman • Related Efforts

  7. 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)

  8. 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

  9. 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
