NA Connectathon 2020 Application and Network Info

  Prepare your system to test at the Connectathon.  Find configuration, IP address, OIDs and other network information here.

Configuration for Connectathon test systems / OIDs

An important Connectathon preparation task for December is to share configuration parameters for your test system (ports, URLs...).

Configuration entry is a two-step process prior to the Connectathon.  We want you to spend your time at the Connectathon working on interoperability issues and not asking your neighbor, "What is the URL of your Repository?"

  1. Starting in December, we collect your system's configuration parameters in gazelle.  Due December 20, 2019.
  2. Then, you retrieve your partners' parameters from gazelle and enter them into your system.  Finish this task before arriving at the Connectathon.

Gazelle assigns you default parameters based on the profiles & actors you signed up to test.  Your task is to update those to actual parameter for your test system and marked them 'Approved'.  This is done in gazelle under menu Configuration-->System Configuration.

Hostnames: Each test system in gazelle is given a hostname.  You can allocate additional hostnames for your systems if you need them.  IP addresses will be assigned to hostnames shortly before the Connectathon.

The gazelle proxy:  The config/ports for the gazelle proxy are shown on the gazelle configuration page in red font.  There is separate training provided about use of the gazelle proxy.

Many systems need OIDs as part of their configuration (Patient ID Sources, XDS Source & Repositories, homeCommunityIDs, others...).  These are assigned in gazelle under menu Configuration-->OIDs for current session.

Any questions about configuration parameters should be sent to Philip DePalo (...after you have viewed the training ;-) )

Training on gazelle configuration entry

There is a a new Gazelle in town. The training for this has changed.

Connectathon Network Description

The connectathon network is the backbone for our interoperability testing.  Please read this before arriving in Cleveland:  NetworkDescription-NA2020.pdf

 IP Addresses

  1. Fixed IP addresses have been assigned for all hostnames you configured as part of your configuration work in Dec/Jan (hosts, ports, URLs, ...).
  2. You can see your IP addresses using Gazelle (
    -- Configurations -> (Company) : Systems Configuration
    -- Select a system
    -- The hosts and IP addresses associated with that system will display at the top
  3. You can see all IP addresses (all systems, including yours, using Gazelle (

Seating Assignments

-- Seating assignments - There are two tabs in this spreadsheet. On the first tab, each cell represents one table with two chairs; table locations are identified by a letter/number, eg L28. The second tab shows seating assignments sorted by Organization. You can use the spreadsheet now for a table location if you need to ship something or order services. Your table location will also be entered in Gazelle before the end of the calendar year (2018). This will show up for you and your partners as you are running tests.

Guidance for Monday's session

We hope you've already reviewed the 10 Connectathon Tips from the Pros.

Monday 8:00-10am is for system set-up.  After 10am, we expect you to perform testing. Here is guidance on goals to accomplish during Monday's testing session:

    • Configure and connect to tools for your profiles.
    • Complete the 5-minute Consistent Time "CT_Client" test
    • Content Creators -- submit CDA/C-CDA docs into the samples area of gazelle for evaluation
    • Modalities/Evidence Creators -- submit DICOM samples into gazelle and the Central Archive
    • Submit media you create to the assigned Monitor -->  give XDM and PDI media to monitor Samantha Neiheisel at table M28.
      • It is good practice to hand a monitor your media rather than just dropping it at the table.
    • Any other tests labeled "*_Do_This_First" or "*_Read_This_First"
    • In general, work on other no-peer tests.
    • Then, move on to peer-to-peer tests.

NA Connectathon DNS


  1. We use a fake domain name ( for Connectathons in North America. Particpant systems are assigned more or more host names (e.g., acme2) and the fully qualified domain name (FQDN) for that host would be
  2. The Gazelle Test Management System ("Gazelle") is hosted at
  3. Some other tools such as the Gazelle Security Suite are hosted at
  4. The server also hosts other content such as documentation.
  5. Prior to the connectathon, these two systems live outside of the Connectathon test room and have public IP addresses:
  6. During the event:
    1. The full server lives in Cleveland on the private network used for testing.
    2. The tooling part of is brought to Cleveland and lives on the private network.
    3. Other content (documentation) remains on the original
  7. The Gazelle Test Management software records URL's that link to items inside the system or inside the system. The software works best if you use the fully qualified domain name in the URL rather than trying to use an IP address or just "gazelle"
  8. In previous years, we have seen evidence that DNS "stuff" from offsite locations such as your hotel might be cached in your system and interfere with your work in the testing area. We have advice below on how to manage that.

What Does This Mean for You?

Manual Network Configuration (i.e., Fixed IP Address)

  1. Make sure you set the Search Domain to:
    1. That means if someone tells you their hostname is acme2 and you try to connect to acme2, your underlying system software should try a DNS lookup on and things should just work.
  2. For DNS servers, use only the server we supply:
    1. If you use a different DNS server, you will not be able to resolve IP addresses for your partner systems.
    2. You will also get redirected to the public IP address of some of the resources listed above, and that will cause a (large) mess.

What Else Should You Do?

  1. After you connect to the Connectathon network, run the following (or equivalent) commands from a console window to determine the IP address of two systems. You should get the answer listed. If you do not get the answers listed, your DNS has a problem and needs to be fixed. You can see Phil DePalo if you need help
    1. nslookup (Answer:
    2. nslookup (Answer:
  2. When you return to your hotel room and decide you need to do more work, you can still connect to and/or Your hotel DNS should give you the public IP address of those systems at home, and you will be redirected to the Convention Center.
    1. When you are in the Convention Center and you use the public IP address for either of those resources, your connection goes out the firewal to the server at home and then gets redirected back through the firewall. The round trip traffic just puts more load on the network for no benefit.
  3. Repeat the first step above (nslookup) every morning when you connect to the Connectathon network. It might have worked on Monday but not on Tuesday.
  4. Resist the temptation to enter a fixed IP address when you browse to Gazelle Test Management ( or to the other tools at

What If?

  • You might have a link to documentation that starts with That should still work inside the Convention Center through redirects. If you have problems getting to such documentation, use this prefix: That URL points to the IHE Europe server back in Rennes and should not have any redirect issues.
    • Do not use this link for anything other than documentation.
    • Do not use this link for any tools

Technical Preparation Resources:

>> Monitors' Profile Assignments:

Monitor profile assignments are in this google spreadsheet.  

We organize IHE profiles with common characteristics or technologies into "clusters", and then we assign monitors to evaluate tests in one "cluster" (perhaps two).  The google spreadsheet contains the first draft of monitor assignments.  We try to assign you to profiles that match your expertise.  We hope that some assignments allow you to learn something new.  During the Connectathon, you will have an opportunity, if you wish, to work in areas outside of your primary assignment. In fact, each monitor has the capability to evaluate tests in almost any profile.

There are two tabs in the spreadsheet:

    • The first "Assignments" tab contains a row for each monitor.  The columns identify the profile "clusters".  The numbers in the column indicate how you will spend your time, eg a "1" indicates you will devote your time evaluating tests in that cluster.  Some monitors are asked to split time between two clusters.   During Connectathon week monitors will have the opportunity to evaluate tests in another area based on your interest or on our need for help in a certain area.
    • The second "Cluster-Profiles" tab identifies the profiles in each cluster.  Each profile listed in Column D contains a link to that profile's documentation.  If the link is to Technical Framework Volume 1, then there is one chapter per profile.  If the link is to a Trial Implementation Supplement, then the entire profile is contained within one document.  The yellow rows also point to available preparation material.

>> Technical Specifications: 

The specifications we test at the Connectathon are contained in IHE Technical Framework documentation.   IHE publishes its Technical Framework documents, organized by domain, on the Technical Framework page of

Each IHE domain's Technical Framework is segmented into multiple volumes; Volume 1 contains the use cases the profile addresses, the process flow and a diagram of the actors & transactions in the profiles. The technical details of the transactions are not in Volume 1, and as a monitor, you do not need to be an expert at that level. If you are reading a Trial Implementation Supplement, you will see that the contents are separated into Volume 1 and Volume 2 within the supplement.

If you are not familiar with IHE documentation, we recommend you view the "Interpreting the IHE Technical Framework" video in the training section below before you read the documentation.

If you have time prior to the Connectathon, we recommend you read the chapter in Technical Framework "Volume 1" for the profiles you are assigned to evaluate. 

We also test HL7 Consolidated CDA® Release 2.1.  Those specifications are here.


>> Monitor training material

While we provide material to enable monitors to do some preparation prior to the Connectathon, we understand the demands of your day job, and we have no requirement for you to do advance prep.

That said, this section contains links to available training material that falls into 4 categories.  

  • The January 8 Connectathon Monitor webinar -- if you have time for only one prep item, this is the one to choose.
  • General training topics -- probably of more interest to first-time monitors
  • Cluster-specific training material -- these trainings are organized according to the 'clusters' of profiles you are assigned to.
