Waitzman Request for Comments: 1149 BBN STC 1 April 1990 A Standard for the Transmission of IP Datagrams on Avian Carriers Status of this Memo This memo describes an experimental method for the encapsulation of IP datagrams in avian carriers. This specification is primarily useful in Metropolitan Area Networks. This is an experimental, not recommended standard. Distribution of this memo is unlimited. Overview and Rational Avian carriers can provide high delay, low throughput, and low altitude service. The connection topology is limited to a single point-to-point path for each carrier, used with standard carriers, but many carriers can be used without significant interference with each other, outside of early spring.

© 2008 Progress Software Corporation8 DEV-5: Did You Get The Message? JMS Messages  Message defines “standard headers” and “message properties”  Standard Headers: JMSDestination, JMSReplyTo, JMSTimestamp, JMSExpiration, JMSDeliveryMode, JMSPriority, JMSMessageID, JMSCorrelationID  Message Properties: user-defined name/value pairs  Subtypes define different types of message body  BytesMessage: stream of bytes  MapMessage: name/value pairs  ObjectMessage: serialized object  StreamMessage: stream of typed primitives  TextMessage: text string or XML document

JMS Administered Objects  “Administered objects” encapsulate things you want to change in deployment, without changing code:  JMS provider, logical destinations, connection and tuning parameters  Queue v. Topic defines distinct “messaging domains”  Most interfaces have domain-specific subtypes
