Sending FLASH Messages Quickly: Techniques for Low Latency Message Switching and Precedence Handling
Click here to download now
Overview: This paper from Isode looks at how messages can be handled to achieve message switching times of a few hundred milli-seconds, for both low and high volumes of traffic. The importance of Permanent Associations as a way of avoiding delays in opening a connection is described and consideration is given to Precedence Handling, describing techniques that ensure high precedence traffic gets optimum (low) latency. The paper explains why message pre-emption is not a useful approach and why DiffServ is important when there are bandwidth limitations.
