RFC 1149 - Carrier Pigeon Internet Protocol
Network Working Group D. 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. [ ... ]

JMS Overview
© 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

Broker is the basic message server Brokers can be Clustered
• A cluster acts like one Brokerin terms of messaging
• Messages are automatically routed to all cluster members
Brokers alone or in a cluster canbe in Primary-Backup CAA™ pairs
A Node is either a broker or cluster Dynamic Routing Architecture (DRA)
• on demand connections between Nodes• Node-to-Node Authorization/Authentication

In Summary
Enterprise Messaging enables• Application Reliability, Availability,
Performance, Scalability• Business Agility through Loosely Coupled
Architecture
SonicMQ enables• Globally Distributed Architecture• Business Continuity with HA built into the
software• Heterogeneous Connectivity (Java, ABL,
J2EE, C, C++, C#, HTTP, SOAP, … )
You need it in case something goes wrong – but more importantly, in case everything goes right!
