Slide 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
Slide 3
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 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!

Discussion
1. Potential Work Items
2. Working Group Charter Strawman
3. Related Efforts
Slide 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)
Slide 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
Slide 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
