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

Agenda

• Welcome
• Agenda Bashing
• Status Update (I-D, rfid_at_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)

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

• 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
