What is MTOM encoding?

MTOM is a mechanism for transmitting large binary attachments with SOAP messages as raw bytes, allowing for smaller messages. By default, the WSHttpBinding sends and received messages as normal text XML. The MTOM encoder can optimize arrays of bytes and streams.

What is message encoding?

Encoding is the process of turning thoughts into communication. The encoder uses a ‘medium’ to send the message — a phone call, email, text message, face-to-face meeting, or other communication tool. The level of conscious thought that goes into encoding messages may vary.

What is encoding in WCF?

Encoding is the process of transforming a set of Unicode characters into a sequence of bytes. Windows Communication Foundation (WCF) includes three types of encoding for SOAP messages: Text, Binary and Message Transmission Optimization Mechanism (MTOM).

Which type of encoding is not provided by WCF?

Use the text message encoder to interoperate with non-WCF endpoints. BinaryMessageEncodingBindingElement, the binary message encoder, uses a compact binary format and is optimized for WCF to WCF communication, and hence is not interoperable. This is also the most performant encoder of all the encoders WCF provides.

What do you need to know about MTOM encoding?

MTOM is a mechanism for transmitting large binary attachments with SOAP messages as raw bytes, allowing for smaller messages. Important. The samples may already be installed on your machine. Check for the following (default) directory before continuing.

When to use MTOM instead of base64 or Base64?

MTOM should only be used on large message transfers because it comes with an overhead. For small size of messages, MTOM’s performance will be worse than Text message encoding (Base64). If MTOM is used for large messages, it’s faster than Base64 since it uses raw binary for data transfer.

How many bytes of data can MTOM send?

MTOM is able to transmit binary data as raw bytes, saving the encoding/decoding time and resulting is smaller messages. The threshold of a few thousand bytes is small when compared to today’s business documents and digital photographs.

How does message transmission optimization mechanism ( MTOM ) work?

This sample demonstrates the use of the Message Transmission Optimization Mechanism (MTOM) message encoding with a WSHttpBinding. MTOM is a mechanism for transmitting large binary attachments with SOAP messages as raw bytes, allowing for smaller messages. The samples may already be installed on your machine.
