Architecture for MTOM based file transfer

Web Services helps in better communication between different applications over the Internet. They can send any type of information using encryption techniques. Different techniques have been used to send binary files as an attachment to SOAP messages. W3C recommends MTOM (Message Transmission Optimization Mechanism) as the standard for transferring binary files as an attachment to SOAP messages. The basic feature of MTOM is that, it transfers the binary data without breaking the XML infoset. However, the work done so far on efficient processing of SOAP attachments is very little. This paper provides architecture for sending binary files as attachment using MTOM. The problem with DIME (Direct Internet Message Encapsulation) is that the binary content is sent outside the SOAP Envelope of the XML message. This means that even if your message is secure, the DIME attachment may not be secure. We realized that when MTOM is used, Web service automatically handles the encoding of the data in the Web service message. The architecture described in this paper for transferring binary files using MTOM will give approximately 10% faster result than DIME. This is because; in MTOM we do not need to package each chunk into the attachment, which is necessary in DIME.
