1. BOB - GSA’s Best Of Breed Protocol

2. Global Gaming Expo - October 2004 BOB: “Best of Breed” - EGM to System

3. Global Gaming Expo - October 2004 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

5. Global Gaming Expo - October 2004 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

6. Global Gaming Expo - October 2004 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)

7. Global Gaming Expo - October 2004 The BOB Classes Core Classes 1) Device ownership & subscriptions 2) Communications 3) Meters & subscriptions 4) Cabinet Class 5) Processor Class Additional Classes 1) Coin Acceptor 2) Note Acceptor & Dispenser 3) Coin Hopper 4) Printer 5) Handpay 6) Progressive 7) Bonus 8) Player 9) Voucher 10) Wagering Account Transfer 11) Game Authentication Terminal

10. Global Gaming Expo - October 2004 BOB: Achievements in 2004 Completed Work  BOB Message Protocol 1.0  BOB Transport / Security Standard 1.0 (SOAP / HTTPS over TCP/IP / Ethernet)  HOST and EGM Simulators Version 1.0 Work in Progress  sBOB - BOB over a serial link (WBXML / PPP )

11. Global Gaming Expo - October 2004 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

12. Global Gaming Expo - October 2004 The Protocol Development Suite S2S BOB

13. Global Gaming Expo - October 2004 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

15. Global Gaming Expo - October 2004 sBOB - BOB over a serial link

16. Global Gaming Expo - October 2004 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

17. Global Gaming Expo - October 2004 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

18. Global Gaming Expo - October 2004 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
