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.
recommended standard.
This is an experimental, not
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 Messages


8
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

JMS Connections
 The actual network connection
 TCP, SSL, HTTP/S
 Authentication Identity
 user/pw, certificate
 Factory for Sessions

JMS Sessions

Sessions create and “own” Producers, Consumers

Sessions create Messages

Sessions define ordered sequence of production, consumption

Brokers, Clusters, Nodes, and DRA
 Broker is the basic message server
 Brokers can be Clustered
Cluster
• A cluster acts like one Broker
in terms of messaging
• Messages are automatically routed to all cluster
members
 Brokers alone or in a cluster can
be in Primary-Backup CAA™ pairs
Broker Cluster

 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!
