BOB - GSA’s Best Of Breed Protocol

Global Gaming Expo - October 2004

BOB: “Best of Breed” - EGM to System


GSA Protocols: Common Business Drivers

Make it easier for operators to install, manage, operate, and administer EGMS and hosts

Reduce the Total Cost of Ownership Continue to support existing functionality Reduce dependence on proprietary solutions Expanded functionality Make it easier to deploy new solutions

What Is BOB?

BOB = Best Of Breed Communications between EGMs and back-end servers Designed to supercede existing protocols Based on current, proven technology standards; XML, SOAP,

Web Services, etc. Expandable from low-speed (BOB messages between an

EGM and SMIB over a serial link) to very high-speed communications (EGM to multiple back-end servers over Ethernet)

Consists of three components: BOB Message Standards BOB Transport Standards BOB Configuration Standards


What Choices Led to BOB?

An open standard data model for an EGM

Satisfies evolving data requirements

Supports namespace extensions

An event driven architecture rather than polled protocol

Host as owner or guest (one can write, any can read)

A messaging protocol that is extensible and is encoded using industry standards, like XML

A messaging protocol that is independent of transport (Ethernet, serial, or dial-up)

Example of XML for meters


BOB XML Request Response Pair

Request

<getMeters>

<getPerfMeters

meterName=“coinIn”

themeId = “sum”

paytableId=“sum”

denomId=“all”

/>

</getMeters>

Response <meterInfo metertype =“onDemand”>

<perfMeter Metername=“coinIn” denomid=“5”meterValue=“50015” />

<perfMeter

Metername=“coinIn”denomid=“25”meterValue=“1003525” />

<perfMeter

Metername=“coinIn”denomid=“100”meterValue=“2504100” />

</meterinfo>


BOB: Achievements in 2004

Completed Work

BOB Message Protocol 1.0

TCP/IP / Ethernet)

HOST and EGM Simulators Version 1.0

Work in Progress sBOB - BOB over a serial link (WBXML / PPP )


BOB: Goals for 2005

Remote configuration of slot machines

Lottery class

Peripheral code download

Central determination (Class II gaming)

EGM operating system and code download

Printer class - template and code download

Protocol Testers for self-certification and verification

Protocol Simulator Overview

EGM Simulator Simulates a slot machine - configured via the User Interface or from a

Host Service

Game Play interface - supports all meters

BOB messaging with multiple hosts, simultaneously

Support for GDS devices

Host Simulator Up to 7 individually configurable Host Services

Full BOB communication with EGM or simulator

Support for multiple concurrent gaming machines

EGM and Host Simulator Demonstration


sBOB - BOB over a serial link


The Challenges

The industry needs an open protocol for older games

A reel spinning game can’t build large XML messages

Serial is not as fast as Ethernet

Goal - Use existing SMIBs to implement BOB now

Need a protocol that works on an embedded processor

Retain the BOB data model, if possible

Continue to use open standards


The sBOB Solution Set

Continues to use the BOB data model

Only changes the transport method

WBXML - encodes XML into binary representation

PPP - Standard for TCP/IP communications over Serial

Can be implemented now


The sBOB Datascope

Allows one to view the sBOB information being transported

Can see raw binary data, PPP packets, or decoded WBXML

Monitors traffic in both directions

Uses the provided sBOB dictionary document
