    • A system and method for exchanging data processing capabilities between computers. The computers exchange capabilities so that data transfer between the computers may be made in the most efficient data format possible for the two computers. A first computer, which will receive a data file, sends a list of data processing capabilities to a second computer, which will transmit the data file to the first computer. The transmitting computer examines the capabilities list of the receiving computer as well as its own capabilities list and determines the most efficient data format for the transfer. The transmitting computer may process the data file into an intermediate format for efficient data transfer so that the receiving computer will process the intermediate data file into the desired data format. The capabilities list can be cached for future communication between the computers. The system can update the capabilities list and inform other computers whether their cached capabilities list is current. Capabilities can also be forwarded from one computer to another so that a third computer can determine the capabilities of the first computer from the second computer or the capabilities of the second computer from the first computer. The system is readily applicable to facsimile machines where custom and application data processing capabilities can be exchanged.
    • 一种用于在计算机之间交换数据处理能力的系统和方法。 计算机交换能力,使得计算机之间的数据传输可以以对于两台计算机可能的最有效的数据格式进行。 将接收数据文件的第一计算机将数据处理能力列表发送到第二计算机,第二计算机将数据文件传送到第一计算机。 传输计算机检查接收计算机的能力列表以及其自身的能力列表,并确定用于传输的最有效的数据格式。 发送计算机可以将数据文件处理为用于有效数据传送的中间格式,使得接收计算机将处理中间数据文件成为期望的数据格式。 功能列表可以被缓存以用于计算机之间的将来的通信。 系统可以更新功能列表,并通知其他计算机,无论其缓存的功能列表是否为最新。 能力还可以从一台计算机转发到另一台计算机,以便第三台计算机可以从第二台计算机确定第一台计算机的功能或从第一台计算机确定第二台计算机的功能。 该系统可以方便地应用于可以交换定制和应用数据处理能力的传真机。

    • The system of the present invention processes data for communication between first and second computers by linearizing the communications message. The message comprises a linear header portion, an extended header portion, and a message body. The linear header portion identifies the number of message recipients and message types. The extended header contains detailed information about the message recipients, such as recipient name and address. The extended header may also contain message subject information, polling information, and password data. The header information is used by the receiving computer to prepare to process the expected data type. The message body may be transferred in a form that takes advantage of the data processing capabilities of the first and second computers. The computers may exchange data processing capabilities so that the most efficient transfer form may be selected. The extended header and message body are encoded using a well-known ASN-1 data encoding process. In addition, the message body may be compressed and encrypted. The system may be readily used in facsimile communication where the first and second computers are facsimile machines.
    • 本发明的系统通过线性化处理通信消息来处理第一和第二计算机之间的通信的数据。 消息包括线性报头部分,扩展报头部分和消息体。 线性标题部分标识消息收件人和消息类型的数量。 扩展头包含有关邮件收件人的详细信息,如收件人姓名和地址。 扩展报头还可以包含消息对象信息,轮询信息和密码数据。 接收计算机使用头信息来准备处理期望的数据类型。 消息体可以以利用第一和第二计算机的数据处理能力的形式传送。 计算机可以交换数据处理能力,以便可以选择最有效的传送形式。 使用公知的ASN-1数据编码处理来对扩展的报头和消息体进行编码。 另外,消息体可以被压缩和加密。 该系统可以容易地用于传真通信,其中第一和第二计算机是传真机。

    • A method and system for processing messages is provided. In a preferred embodiment of the present invention, a message scheduler, a job process, and a format resolution module are used. The message scheduler identifies when a new message is to be processed, schedules the new message for processing, invokes the format resolution module to determine a method of converting data in the message to an appropriate format for a destination device or file, and invokes a job process. The format resolution module determines an appropriate method for converting data in the message from a format acceptable to the source devices or files to a format acceptable to the destination devices or files and creates a target message containing a reference to a destination device or file. The job process sends the data between the source devices or files to a destination device or file and performs the appropriate conversion. The preferred embodiment of the present invention is designed to allow for the support of new devices and new data formats with little change to the existing system through the use of a building block methodology. Therefore, new devices and data formats can be supported in an easy and efficient manner.
