SLRRP spurs large-scale RFID rollouts

By Mike Grady

Radio frequency identification readers were originally operated
as peripherals typically connected to a host computer via a
serial port to support a dedicated application. This works OK
for deployments involving modest numbers of readers performing a
specific targeted business function, but to accommodate
large-scale RFID production environments, readers are evolving
to support TCP/IP stacks connected via wired or wireless
networks.

A typical RFID deployment would consist of a network of RFID
readers controlled by one or more Reader Network Controller
(RNC) element. Implemented in the form of software in a server,
embedded software in a router or switch, or a stand-alone
device, this controller provides the control and data path
interface to a reader network. The RNC is connected to servers
running RFID-enabled client applications, as well as management
applications that monitor operations of the reader network.

This network-centric architecture calls for a simple, flexible
controller-to-reader protocol. The IETF is deciding on
chartering a working group to develop the Simple Lightweight
RFID Reader Protocol (SLRRP [pronounced "slurp"]). SLRRP is a
proposed protocol for use in an IP-based network to convey
configuration, control parameters, status and tag information to
and from readers.

Reduce Fire Safety Risk in Your Network!

Concerns are rising about the growing number of combustible
cables present in buildings required to service the
ever-increasing demands of IT networks. More workstations are
taxing the infrastructure. These concerns are the thrust behind
new "limited combustible" cables that reduce fire safety risk.
