CONNECT 4.0 New Features ① Increased throughput targeting increased numbers of PD, QD, RD, AD, and DS transactions ② Exchange and process large payload sizes of up to 1 GB ③ Run CONNECT on additional application servers such as IBM WebSphere and Oracle WebLogic to meet their environment needs ④ More comprehensive event logging and metric data ⑤ Ability to determine the state of a transaction across messages in order to better review and analyze the operation of CONNECT and adopters’ trading partners ⑥ Minimize deployment load by supporting a lightweight gateway which allows smaller server footprint and use of system resources ⑦ Support Direct messages to allow for greater adoption and exchange 4

Agenda Updated tech stack -Enables : +increased throughput, +large payload sizes, and +multi-app support Improved performance Large payloads Event logging -How it works and how you can use it Transaction logging “Lightweight gateway” -Current users – changes to be noted -Direct 5

Updated Tech Stack Support for WebLogic, WebSphere, and GlassFish application servers –Deploy via an Enterprise Archive Web service stack introduced to expand CONNECT’s capabilities –Apache CXF replaces Metro Source code now at GitHub –Simplified code contribution process Build with maven –Better dependency management –Replaces ant –Easier project setup 6

Start developing Get the CONNECT 4 Source –Checkout source: git clone Solution/CONNECT.git. –Alternatively, create a fork of our repo and clone your fork: git clone /CONNECT.git. /CONNECT.git – git checkout Compile Source – Mvn clean install Request Enhancements or Log Issues – Submit Code – Follow the “how to contribute code” wiki page: 7

Increased Throughput 8 Achieved through: Reduction in memory usage ApacheCXF & OpenSAML Reduced number of static classes Fewer number of web services running Removed redundant and duplicative code flows *These numbers are based on the same testing methodology performed during the CONNECT benchmark testing for release 3.3. Document Submission Patient Discovery Document Retrieve Document Query Messages per Second CONNECT 4.0 CONNECT 3.3 CONNECT CONNECT 3.1

Large Payloads Using Streaming Web Services using HTTP “Chunking” –Minor wsdl file change – does not affect interoperability. –“Over the wire” message is unchanged File size limited only by network and server capabilities –No longer limited by memory available to the server Backwards compatible –Up to limitations of partner gateway. 9

Event Logging Goals and Data Points Two formal high level business goals: CONNECT provides the ability to count and produce durations for the following values: Number of a given transaction type (PD, QD, RD, etc.) Number of a given transaction group Number of transactions from a specific gateway Total duration for given transaction type Total duration for a given transaction group CONNECT can track and report on the following data points: Error Performance Transaction Type Payload Error Messages log (without PHI data) 10

Event Logging CONNECT captures lifecycle events for inbound and outbound messages Event logging framework can be extended to: –Add new event types –Record events in different manners –Customized what details are recorded 11

Transaction Logging Transaction Logging Example 18 Database and log output for a related transaction chain (Patient Discovery, Document Query, and Document Retrieve messages as a single transaction) Note that there are two transaction entries logged for each service The response Nhin message ID was logged based on its RelatesTo message ID

“Lightweight Gateway” Reduction of endpoints “Entity” now called “Standard” (“Pass-through” remains) Configurable 19

Direct SMTP message transaction CONNECT leveraged Direct Project RI How to use CONNECT Direct: –Configure your own organization’s mail server –Use your regular mail client –Or your EMR’s mail client –Or, use SOAP+XDR Tool for Stage 2 Meaningful Use 24

Join Us for Sprint Review + Planning 26 Join us for sprint review and planning sessions, every other Monday, 10am-noon ET. The CONNECT product team will share the work of the last sprint for community review and feedback. We’ll then transition into a high-level planning session to set the themes for the coming sprint, in the context of the product roadmap. Community input and insights are welcome, so please join us! The meeting will start with a review of the work accomplished during the past sprint which leads into a planning discussion for the upcoming sprint, we flow from one topic to another based on content, questions and conversation. Sprint Review + Planning: Every other Monday 10am-12pm ET (next one: Feb 24) Tel: Participant Code: Web: (meeting id )

Upcoming Events February 11, 2013 CONNECT Release 4.0 February 25, 2013 (10am ET) Next Sprint Review + Planning meeting March 4 - 7, 2013 HIMSS Interoperability Showcase demo Spring 2013 (date to come, D.C. area) CONNECT User Group Meeting 27
