SLRRP BoF Overview 62 nd IETF

This overview provides context and examples of RFID tagged goods in various industries, such as retail stores, manufacturers, warehouses, and distributors. It introduces the Simple Lightweight RFID Reader Protocol (SLRRP), which aims to standardize RFID infrastructure operations based on scalable networking principles. The proposal includes a control and data access protocol for scalable deployments, with network management and operations to follow. This update includes the progress made since the WG exploration process started in October 2004.

  3. Deployment Today Manageable in small numbers...

  4. Deployment Tomorrow Each reader can put out 40x the RF power of a Wifi access point... What if all these IP devices were on your network...?

  5. SLRRP • Simple Lightweight RFID Reader Protocol • Goal to bring IP network-based RFID operations into the IETF family for standardization • Proposal to start with control and data access protocol (SLRRP) for scalable infrastructure deployments • Network management and operations to follow • Agenda includes presentations from RFID and networking companies

  6. Status Update • Started WG exploration process in Oct ’04 with goal to standardize RFID infrastructure operations based on open, scalable networking principles. • 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!

  7. Thanks! See you at the BoF – Tuesday 1300

  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
