In one embodiment, the gaming machine 50 may comprise video gaming machines manufactured by Bally Technologies, Inc. or other manufactures.
FIG. 3 illustrates one embodiment of a gaming machine 50. As depicted, the gaming machine 50 comprises a microprocessor 70 and non-volatile memory 75 that stores one or more gaming applications 80, which are run by the microprocessor 70. The gaming machine 50 further includes a video display 85, such as an LCD display, through which the gaming applications are presented to the casino patrons. The gaming machine 50 may further include a user input device 90, such as a keyboard or various game-specific buttons (e.g., bet one, bet all and the like). In one embodiment, the user input device 90 may include a touch screen. In some embodiments, the touch screen overlays the video display 85. The gaming machine 50 may also include various in-game devices 95, such as credit card readers, coin and bill acceptors, casino patron card readers, and the like. In one embodiment, an in-game device 95 may comprise an embedded additional user interface (not depicted), such as an IVIEW interface described in the commonly owned U.S. patent application Ser. No. 10/943,771, entitled USER INTERFACE SYSTEM AND METHOD FOR A GAMING MACHINE, which is incorporated by reference herein. In one embodiment, the gaming machine 50 also includes a network interface 55 and a serial interface 60, which may be connected to a serial-to-network adapter 65, purpose of which will be described in greater detail hereinbelow.
As indicated above, the gaming machine 50 comprises network interface 55, such as a network card, which facilitates IP-based communication with other networked devices. In a preferred embodiment, the network interface 55 may be operative under the control of the processor 70 to communicate with devices external to the gaming network 12, such as back office network servers, through network switch 45 and router 40, as will be described in a greater detail below. For example, the network interface 55 may be used to download gaming applications or updates thereto from the application server 20. The network interface 55 may also be used to communicate with the billing server 25 when casino patrons place wagers using credit or debit cards. In another example, the network interface 55 may be configured to communicate with user authentication server 30, which maintains information about casino patrons. This information may be used to monitor patrons' winnings and rewards and to provide various personalized services to the casino patrons. In yet another example, the network interface 55 may be used by “in game” devices, such as the IVIEW interface, to communicate with external computers servers, which provide advertisements and promotions-related information that is displayed on the IVIEW interface. The network interface 55 may be used for other purposes known to those of skill in the art.
As indicated above, the gaming machine 50 also includes a serial interface 60, such as a Universal Serial Bus (USB), FireWire, High-Speed Serial Interface (HSSI), or the like. In a preferred embodiment, the serial interface 60 may be under the control of the processor 70 and communicate with devices internal to the gaming network 12, such as other gaming machines 50. In a particular embodiment, the serial interface 60 may be dedicated to intra and inter-game communications, such as communications among gaming applications that run across several gaming machines 50 in the gaming network 12. For example, the serial interface 60 may be used by the gaming applications in a progressive networked gaming system in which several gaming machines 50 in a gaming network 12 compete for, and contribute to, a single jackpot price. In this networked gaming system, the gaming applications 80 may use serial interface 60 to exchange messages for synchronizing jackpot values, notify each other about winnings, and exchange other game-related information. In another embodiment, gaming applications 80 may communicate through serial interfaces 60 to set up group plays or tournaments across several gaming machines 50. Those of skill in the art will appreciate that there may be other applications of the serial interfaces 60.
To facilitate communication between the gaming applications 80 through the serial interfaces 60, the gaming machines 50 may be further equipped with serial-to-network adapters 65. For example, a serial-to-network adapter may include USB-to-Ethernet adapter, such as Netgear® USB 2.0 Fast Ethernet Adapter, or a USB-to-Wireless adapter, such as Lynksys® Wireless-G USB Network Adapter, or other types of adapters known to those of skill in the art. In one embodiment, the gaming machines 50 may be connected through their serial interfaces 60 and adapters 65 to a networking device, such as the aforementioned network switch 45. In another embodiment, another networking device, such as switch or a router may be used to interconnect gaming machines 50 through their serial interfaces 60. Furthermore, to communicate through the serial-to-network interfaces, the gaming applications 80 may use a custom network protocol, such as one based on Universal Datagram Protocol (UDP), Transmission Control Protocol (TCP), or other network protocols known to those skilled in the art.
Referring again to FIG. 2, in one embodiment the gaming network 12 may include a network switch 45 or a similar networking device that facilitates data communication between gaming machines 50 and networking devices external to the gaming network 12. To that end, the network switch 45 may be connected to the network router 40. The switch 45 may be implemented as programmable hardware or software network device, such as a switch, a router, an access point, or the like. In a preferred embodiment, the switch 45 may have an OSI Layer 2 (i.e., data link) and/or Layer 3 (i.e., network layer) switching capability. In addition, the switch 45 may support either a DHCP, BOOTP or similar IP address distribution protocol, as is described in greater detail below. In one embodiment, the in-game switch 60 includes a hardware-based network switch that supports DHCP, such as 3Com® 8800 series switches, Cisco Systems® Catalyst switches, Netgear® switches, Lynksys® switches, or the like. In alternative embodiment, the in-game switch 60 may be implemented as a software component stored in the non-volatile memory of one of the gaming machines 50 in the gaming network 12.
In a preferred embodiment, the network switch 45 includes twice as many data ports as there are gaming machines 50 in the give gaming network 12. In the event, a single switch does not have the sufficient number of data ports, additional switches may be connected to the switch 45 to provide the required number of data ports. In one embodiment, the data ports of the network switch 45 may be individually programmed to configure gaming machines connected thereto into one or more Virtual LANs (VLAN). Thus, in one embodiment, network devices connected to one set of data ports of the network switch 45 may be configured into a first VLAN and network devices connected to another set of data ports may be configured into a second VLAN. The first and second VLAN may be logically separated from each other and have independent data communication policies. As a result, data communications between network devices on the first VLAN may not be visible to the network devices on the second VLAN, thereby ensuring isolation and security of the two VLANs.
Referring again to FIG. 2, the gaming machines 50 may be connected to the network switch 45 in the following manner. In one embodiment, the gaming machines 50 may be connected through their network interfaces 55 to the first set of data ports of the network switch 45, thus forming a first VLAN. As indicated above, the network interfaces 55 may be configured to communicate with devices external to the gaming network 12, such as back office network servers. Therefore, the first set of data ports may be configured to direct all communications from the network interfaces 55 to the network router 40 and subsequently to the back office network servers. Otherwise stated, all communications from the external network devices, such as network servers, may be directed by the network switch 45 to the first set of data ports to which the gaming machines 50 are connected through their network interfaces 55. Accordingly, the first VLAN is dedicated to “external” communications.
Moreover, the gaming machines 50 may also be connected through their serial interfaces 60 via serial-to-network adapters 65 to the second set of data ports of the network switch 45, thus forming a second VLAN. As indicated above, the serial interfaces 60 are configured to communicate with devices internal to the gaming network 12, such as other gaming machines. Therefore, the second set of data ports may be configured to direct all communications from the serial interfaces 60 via serial-to-network adapters 65 to the network devices connected to second set of data ports. Furthermore, the second set of data ports may be configured not to accept any incoming or outgoing external communications. Accordingly, the second VLAN may be dedicated to “internal” or game-related communications only. Thus, the internal and external data communications are separated from each other both at the device and network levels.
In one embodiment, the network switch 45 may be configured to assign IP addresses to the network devices connected thereto. The IP address information may be provided to the network switch by the DHCP server 35 during system startup according to one embodiment. In another embodiment, the switch 45 may be manually configured by the system administrator with a default set of IP addresses. More specifically, the DHCP server 35 may transmit an IP address scope to the network switch 45 using, for example, DHCP, BOOTP or similar IP address distribution protocol. From the received IP address scope, the network switch 45 may assign IP addresses to the network devices connected to the first set of data ports and to the network devices connected to the second sets of data ports. Alternatively, the network switch may assign default IP addresses to the network devices connected thereto. Using the assigned IP addresses, the gaming machines 50 may communicate with the external network devices through the network interfaces 55, and with each other through the serial interfaces 60.
FIG. 4 illustrates a flow diagram of method for configuring a gaming network having a plurality of gaming machines in accordance with one embodiment. In step 410, a network switch is provided into the gaming network. The switch may have two sets of data ports, which can be independently configured. Each gaming machine may be connected through its network interfaces to the first set of data ports of the network switch, step 420. Then, each gaming machine may be connected through its serial interface and serial-to-network adapters to the second set of data ports of the network switch, step 430. The switch may then be configured to assign IP addresses to the network devices connected to its data ports, step 440. The first and second sets of data ports of the network switch may then be configured into first and second VLANs, steps 450 and 460, so that devices connected to the first and second data ports are logically separated from each other. The first set of data ports may then be configured to direct all communication from the device in first VLAN to the devices external to the gaming network, step 470. The second set of data ports may in turn be configured to direct all communications on the second VLAN to the devices internal to the gaming network, step 480.
In summary, the disclosed systems and methods provide a dynamic and scalable networked gaming system, in which a plurality of gaming machines are connected to a network switch to form a hybrid peer-to-peer gaming networks. The gaming switch has two sets of data ports configured into two VLANs. The first set of data ports is connected to the network interfaces of the gaming machine to form a first VLAN. The second set of data interfaces is connected via serial-to-network adapters to the serial interfaces of the gaming machines to form a second VLAN. The first VLAN may be dedicated to communications with devices external to the gaming network. The second VLAN may be dedicated to communications with devices internal to the gaming network. Thus, all server communications may be conducted on the first VLAN, and all game-related communications may be conducted on the second VLAN. The resulting hybrid peer-to-peer gaming network is highly secure and readily scalable. First, external and internal communications are segregated both at the device level and at the network level, which ensures security of the data transmissions. Second, the gaming network may be easily scaled by adding additional gaming machines and network switches to the network. Moreover, this network configuration simplifies both system and network resource allocation and facilitates implementation of highly complex gaming applications that can run across several gaming machines.
A preferred embodiment is directed towards a dynamic and scalable gaming system that includes a plurality of gaming machines connected into one or more hybrid peer-to-peer local-area gaming networks. Each gaming network may be dedicated to one or more gaming applications. For example, there may be a gaming network of blackjack dedicated gaming machines, a gaming network of craps-dedicated gaming machines, a gaming network of roulette gaming machines, and the like. These gaming networks may generally be autonomous and may be independently configured and managed. For example, within each network, the gaming machines may be configured into a master-slave configuration, with one machine acting as a master to the remaining slave machines. This architecture facilitates execution of gaming applications that run across several gaming machines, such as group plays, tournaments and progressive gaming applications.
To further facilitate execution of multi-machine gaming applications in a casino environment, gaming machines within each network are preferably able to directly communicate with each other. To that end, in a preferred embodiment, the gaming machines within each gaming network communicate with each other through their serial interfaces, such as a universal serial bus (USB) interface, rather than through their network interfaces, which may be dedicated to communication with network devices external to the given gaming network, e.g., gaming servers. Using serial interfaces for intra-game communications enables a gaming application to exercise full control over serial interfaces, thereby simplifying system programming. In addition, serial interfaces may be dedicated to intra-game communications, which simplifies system resource allocation. Moreover, by not using network interfaces, the gaming applications do not consume network resources and do not generate application-related network traffic outside the gaming network.
Preferably, each gaming machine includes a serial-to-network adapter, such as USB-to-Ethernet adapter, which may be connected to the serial interface of the gaming machine in order to facilitate networking of the gaming machines through serial interfaces. The network ends of the adapters may be connected to a first set of data ports of the network switch or similar networking device. The switch may be configured to organize gaming machines connected to the first set of data ports into a first virtual local area network (VLAN) dedicated to internal communications. In one embodiment, the network switch may be configured to manage and distribute “internal” IP addresses to the gaming machines connected to the first set of data ports. The gaming machines may use internal IP addresses to exchange game-related information with each other. The resulted peer-to-peer gaming network is highly secure because it is dedicated to communication of game-related information. In addition, the network is readily scalable to accommodate additional gaming machines that can be connected to the network switch.
As indicated above, the network interfaces of the gaming machines may be used to communicate with network devices external to the gaming network, such as various remote computers servers. To that end, the network interfaces of the gaming machines may be connected to a second set of data ports of the network switch or to another networking device, which would configure gaming machines into a second VLAN dedicated to external communications. In one embodiment, the network switch may be configured to manage and distribute “external” IP addresses to the gaming machines to be used for communicating with devices external to the gaming network. In this manner, all internal and external data communications on the gaming network are separated from each other both at the device and network level, which simplifies resource allocation and improves security of the system.
Furthermore, the various embodiments described above are provided by way of illustration only and should not be construed to limit the disclosed embodiments. Those skilled in the art will readily recognize various modifications and changes that may be made to the disclosed embodiments without following the example embodiments and applications illustrated and described herein, and without departing from the true spirit and scope of the disclosed embodiments, which is set forth in the following claims.
