Hi all- The GLIF NSI Interop Plugfest will be using existing servers for the tests. I.e. Since the NSAs will need to run in the wild anyway, there was little to be gained by moving them to laptops in Rio. So, at the recent OGF NSI meeting, we elected to allow implementation teams to host their NSAs on any server they chose - presumably their development servers at their home facilities. It has been brought to my attention that interoperability testing may be constrained by firewalls in the various networks. I am curious about this - is this a broad based problem that the NSAs will generally be behind firewalls and that block web services? (... Don't all of the web services run under the HTTP or HTTPS ports?) Please let me know your particular exposure to this issue. And since some of the implementations need to deal with this, I would ask that everyone send me the IP addresses that your NSAs will be using, and identify which ports the server will use. I will circulate this to the implementation teams. Note: For interop testing, you will be required to run multiple NSAs such that they are verifiably independent instances (such as would be the case for two independent domains using the same software package for their NSA.) One way to accomplish this would be to use separate hdw servers with separate IP addresses. Thus, you may want to identify several IP addresses that will or might host NSAs. Also, if you require firewall holes for remote access to reach your development facility from Rio, let me know and I will ask the hosts what CIDR blocks we'll be using. A detailed Interop plan with the Challenge details will be forthcoming in the next day or so for review and comment. (I simply need to comlplete some details on one of the last Challenge.) Thanks Jerry
