Abstract
A method and a multiprotocol network CD-ROM server for providing computer network users possibility to share information on CD-ROM, regardless of other file servers and their locations. The CD-ROM server is a self contained piece of hardware. It provides users connected to different computer networks, using various network protocols, shared access to information of any CD-ROM disc inserted into a connected CD-ROM drive.
Claims9
A method of providing computers connected to different networks using various network protocols, with shared access to files from any CD-ROM disc inserted into CD-ROM drives coupled to the computers via a server, and the method comprising the acts implemented on the server of:
- receiving datapackets from the computers each requesting a file access operation in one of a plurality of application protocols;
- identifying the transport protocol used in each of said datapackets;
- creating jobs for each of the datapackets with each job defined in a selected one of a plurality of application protocols associated with the corresponding transport protocol identified in said identifying act;
- translating each of the jobs created in said act of creating from the associated one of the plurality of application protocols into a file access operation;
- and
- executing each of the jobs translated in said act of translating to perform the file access operation requested in said act of receiving.
A multiprotocol network CD-ROM server, providing computers coupled to different networks using various network protocols with shared access to files from any CD-ROM disc inserted into CD-ROM drives coupled to the computers via the multiprotocol CD-ROM server;
- and the CD-ROM server comprising:
- a network module receiving datapackets from the computers each requesting a file access operation in one of a plurality of application protocols and identifying the transport protocol used in each of said datapackets;
- a job module for creating jobs for each of the datapackets with each job defined in a selected one of a plurality of application protocols associated with the corresponding transport protocol identified by said network module;
- a plurality of application modules each translating an associated one of the plurality of application protocols for each of the jobs created by said job module into a file access operation;
- and
- a file system module for executing each of the jobs translated by said plurality of application modules to perform the file access operation requested by the computers.
A multiprotocol network CD-ROM server, providing computer network users possibility to share information on CD-ROMs, providing users connected to different computer networks, using various network protocols, shared access to information from any CD-ROM disc inserted into a CD-ROM drive connected to the server, comprising:
- means receiving a data packet from a sender via the computer network,
- means for storing a protocol stack,
- means for identifying, among protocols in said protocol stack, the transport protocol used in said packet;
- means for creating a transport protocol inpacket of said packet;
- means for decoding said transport protocol inpacket to find out the application protocol used;
- means for creating an application protocol inpacket;
- means for decoding said application protocol inpacket to identify an executable operation in accordance with an implemented operation of said application protocol;
- means for decoding and translating said operation into a file system operation;
- means for performing said file system operation;
- means for making an answer packet to said sender according to said transport protocol;
- and
- means for sending said answer packet to said send.
