Protocol Usage and Benefits to BoB

DHCP Dynamic Host Configuration Protocol

Automatic network admission and IP Address assignment for gaming machines and host systems.

LDAP Lightweight Directory Access Protocol

Automatic configuration of gaming machines and host systems. Automatic notifications of configuration updates. Can store arbitrary binary objects including images, software updates, etc. Provides a secure access control mechanism to allow only authorized users to gain access to the portions of the LDAP directory they are allowed to access.

NTP Network Time Protocol

Automatic synchronization of time across all gaming machines and host systems in a gaming network.

SOAP/HTTP/TCP Simple Object Access Protocol/Hypertext Transfer Protocol/Transmission Control Protocol

Transport layer protocols to carry point-to-point ordered and reliable BoB XML messages between gaming machines and host systems.

XML Extensible Markup Language

All messages between gaming machines and host systems are encoded in XML. XML allows a flexible and extensible method of encoding data.

XML Schema The BoB protocol defines a set of XML schema. A schema is a blueprint for what an XML document can contain.

SSL Secure Sockets Layer

All messages between gaming machines and host systems are secured using SSL. SSL is used to authenticate both ends of a communication session and to encrypt all traffic flowing on that session.

Why XML?Why XML?

BoB strategy is to use “Off the Shelf” standards from computer industry Reduces engineering costs – training, etc Proprietary solutions are more difficult to implement and incompatible on the

casino floor Enables manufacturers to deliver products more quickly and focus on value

added game content

XML is a language useful for defining data exchange XML is a rich language for expressing data structures and defining the

interface (schema) Easily extensible to ensure backwards compatibility

Implementing Products with XML Rapid development environment Numerous tools support XML including most major browsers Integrates well with HTML and other Web standards Human readable and understandable protocol traces Allows automatic data validation against schema for development and

debugging
