The EIP icons library is available as a Visio stencil file adapted to render the icons with the Camel color : sand. Download it here for your presentation, functional and technical analysis documents. The original EIP stencil is also available in OpenOffice 3.x Draw (thanks to Marco Garbelini) , Microsoft Visio, or Omnigraffle.

Messaging Systems  Image Removed  Image Added | Message Channel | How does one application communicate with another using messaging? |  Image Removed  Image Added | Message | How can two applications connected by a message channel exchange a piece of information? |  Image Removed  Image Added | Pipes and Filters | How can we perform complex processing on a message while maintaining independence and flexibility? |  Image Removed  Image Added | Message Router | How can you decouple individual processing steps so that messages can be passed to different filters depending on a set of conditions? |  Image Removed  Image Added | Message Translator | How can systems using different data formats communicate with each other using messaging? |  Image Removed  Image Added | Message Endpoint | How does an application connect to a messaging channel to send and receive messages? |
Messaging Channels  Image Removed  Image Added | Point to Point Channel | How can the caller be sure that exactly one receiver will receive the document or perform the call? |  Image Removed  Image Added | Publish Subscribe Channel | How can the sender broadcast an event to all interested receivers? |  Image Removed  Image Added | Dead Letter Channel | What will the messaging system do with a message it cannot deliver? |  Image Removed  Image Added | Guaranteed Delivery | How can the sender make sure that a message will be delivered, even if the messaging system fails? |  Image Removed  Image Added | Message Bus | What is an architecture that enables separate applications to work together, but in a de-coupled fashion such that applications can be easily added or removed without affecting the others? |
Message Construction  Image Removed  Image Added | Event Message | How can messaging be used to transmit events from one application to another? |  Image Removed  Image Added | Request Reply | When an application sends a message, how can it get a response from the receiver? |  Image Removed  Image Added | Correlation Identifier | How does a requestor that has received a reply know which request this is the reply for? |  Image Removed  Image Added | Return Address | How does a replier know where to send the reply? |
Message Routing Image Removed Image Added | Content Based Router | How do we handle a situation where the implementation of a single logical function (e.g., inventory check) is spread across multiple physical systems? |  Image Removed  Image Added | Message Filter | How can a component avoid receiving uninteresting messages? |  Image Removed  Image Added | Dynamic Router | How can you avoid the dependency of the router on all possible destinations while maintaining its efficiency? |  Image Removed  Image Added | Recipient List | How do we route a message to a list of (static or dynamically) specified recipients? |  Image Removed  Image Added | Splitter | How can we process a message if it contains multiple elements, each of which may have to be processed in a different way? |  Image Removed  Image Added | Aggregator | How do we combine the results of individual, but related messages so that they can be processed as a whole? |  Image Removed  Image Added | Resequencer | How can we get a stream of related but out-of-sequence messages back into the correct order? |  Image Removed  Image Added | Composed Message Processor | How can you maintain the overall message flow when processing a message consisting of multiple elements, each of which may require different processing? |  | Scatter-Gather | How do you maintain the overall message flow when a message needs to be sent to multiple recipients, each of which may send a reply? |  Image Removed  Image Added | Routing Slip | How do we route a message consecutively through a series of processing steps when the sequence of steps is not known at design-time and may vary for each message? | | Throttler | How can I throttle messages to ensure that a specific endpoint does not get overloaded, or we don't exceed an agreed SLA with some external service? | | Sampling | How can I sample one message out of many in a given period to avoid downstream route does not get overloaded? | | Delayer | How can I delay the sending of a message? | | Load Balancer | How can I balance load across a number of endpoints? | | Multicast | How can I route a message to a number of endpoints at the same time? | | Loop | How can I repeat processing a message in a loop? |
 Image Removed  Image Added | Content Enricher | How do we communicate with another system if the message originator does not have all the required data items available? |  Image Removed  Image Added | Content Filter | How do you simplify dealing with a large message, when you are interested only in a few data items? |  Image Removed  Image Added | Claim Check | How can we reduce the data volume of message sent across the system without sacrificing information content? |  Image Removed  Image Added | Normalizer | How do you process messages that are semantically equivalent, but arrive in a different format? | | Sort | How can I sort the body of a message? | | Validate | How can I validate a message? |
Messaging Endpoints | Messaging Mapper | How do you move data between domain objects and the messaging infrastructure while keeping the two independent of each other? |  Image Removed  Image Added | Event Driven Consumer | How can an application automatically consume messages as they become available? |  Image Removed  Image Added | Polling Consumer | How can an application consume a message when the application is ready? |  Image Removed  Image Added | Competing Consumers | How can a messaging client process multiple messages concurrently? |  Image Removed  Image Added | Message Dispatcher | How can multiple consumers on a single channel coordinate their message processing? |  Image Removed  Image Added | Selective Consumer | How can a message consumer select which messages it wishes to receive? |  Image Removed  Image Added | Durable Subscriber | How can a subscriber avoid missing messages while it's not listening for them? | | Idempotent Consumer | How can a message receiver deal with duplicate messages? |  Image Removed  Image Added | Transactional Client | How can a client control its transactions with the messaging system? |  Image Removed  Image Added | Messaging Gateway | How do you encapsulate access to the messaging system from the rest of the application? |  Image Removed  Image Added | Service Activator | How can an application design a service to be invoked both via various messaging technologies and via non-messaging techniques? |
System Management  Image Removed  Image Added | Detour | How can you route a message through intermediate steps to perform validation, testing or debugging functions? |  Image Removed  Image Added | Wire Tap | How do you inspect messages that travel on a point-to-point channel? | | Log | How can I log processing a message? |
