Definitions
- the present invention relates to communications management and is more particularly, although not exclusively, concerned with the management of communication between peripheral devices within a virtualised communications system for airports.
- a peripheral manager containing device drivers forms part of a client computer system which is geographically local to and is directly connected to one or more peripherals via a local communications system.
- a peripheral manager is constrained in establishing communications with central server-based applications due to the use of non-static internet protocol (IP) addresses and the requirement for IP address translation when the communication needs to traverse networks comprising a mix of public and private addressing schemes.
- IP internet protocol
- workstations including thin client devices, mobile/tablet devices
- peripheral devices may be shared for multiple airline usage.
- different airlines tend to utilise different systems and a problem arises where the same peripheral devices need to communicate with those different systems.
- One way of providing such communication requires the adaptation of existing client applications and print emulators to target remote hostnames in conjunction with addressing schemes based on fixed IP addresses.
- this is problematic for a number of reasons, including: the limited availability of public IP addresses; the complexity associated with security, firewalls and mobile data modes where 3G and/or 4G networks are used; the need for many routing configurations that need to be established and effectively managed; and the need to manage multiple stakeholders providing different elements of the communications, for example, airport authorities, network providers, airport information technology providers etc.
- US-B-8032353 describes a bridged computer system in which a host computer executes peripheral driver software associated with a remote client computer and communications between the host computer and the remote client is processed using peripheral emulation of an audio codec. Audio signals are communicated between the host and remote computer using network interfaces provided in both the host and the remote computer. In the host computer, an audio interface is provided which connects to a communications network, and, in the remote computer, interfaces are provided for connecting to speakers and a microphone associated with the remote computer.
- a peripheral emulator including an audio controller emulator and a codec emulator is provided in the host computer for connecting to the host computer network interface, the peripheral emulator implementing transcoding functions, such as, compression of outbound audio data samples and/or decompression of inbound audio samples.
- a link interface which terminates audio links by providing a physicai interface, bus transceiver logic and transport layer termination, the link interface transmitting output audio data and commands, receiving input audio data and responses, communicating codec control information to codec modules, distributing a sample clock, executing a power mode state machine, and providing bus reset and initialisation functions.
- Registers associated with the link interface maintain the configuration states of the codec modules and these registers are emulated at the host computer so that audio software on the host computer has rapid access to codec state information during driver initialisation or when the remote computer is disconnected.
- a peripheral interface including a peripheral emulator in the host computer is connected to the network, and a peripheral controller is provided in the remote computer for controlling a peripheral.
- the peripheral emulator in this case interacts with the driver software to emulate the interface of the peripheral.
- the peripheral interface interacts through the network with the peripheral controller within the remote client computer, the peripheral controller comprising a remote driver or other software and/or hardware for coupling to the peripheral.
- !t is a further object of the present invention to enable virtualised applications running on a server to establish communications with client-based peripheral managers and their associated peripheral devices.
