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

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 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
