Reva Systems, a venture-backed company specialising network-intelligent enterprise architecture for RFID installations, has launched an open source implementation of the Simple Lightweight RFID Reader Protocol (SLRRP) within the SourceForge.net open development community.
Working with industry standards bodies, consortiums, reader vendors, and reader silicon merchants, Reva has been facilitating the definition of SLRRP as an open standard for RFID reader control and data transport in Internet Protocol (IP) networks. Links to the SLRRP draft specification and mailing-list may be accessed directly at its SourceForge web address (http://slrrp.sourceforge.net).
This effort works hand in hand with the definition of standard RFID air protocols, which govern reader and tag interactions. According to Reva, SLRRP will support existing air protocols (such as Auto-ID Class 0/1 and ISO 18000-6b) as well as recently developed standards including EPCglobal UHF Gen2 and ISO 18000-6c. The company also says that SLRRP is future-proofed, having been designed to allow the introduction of new air protocols via its plug-in internal architecture.
Call for open development
According to Reva, the main benefit of this effort to the RFID end-user community is arguably a reduction in the inefficiency and confusion inherent in more than a dozen proprietary reader protocols.
The introduction of open source projects such as this is aimed at encouraging incumbent RFID reader vendors, new market entrants and technology suppliers to actively participate in the ongoing development, refinement and testing of the SLRRP protocol in a public forum.
According to David Husak, CTO of Reva Systems, "The implementation of a standard such as SLRRP will ultimately allow enterprises to select best-of-breed readers that operate seamlessly with their RFID applications and enterprise network infrastructure."
