Hi, I searched the archive of the list for Port and for xRSL, and found nothing, though I want to throw in my two cents: 1. Port In the Network section of a WSDL file I didn't found any way to request specific ports to be opened for incoming/outgoing/tcp/udp connections and if net is NAT'ed etc. I have quite often submitted jobs with need for specific ports and it would hence be nice to be able to specify this in stead of having the job fail. 2. xRSL As JSDL is based on Condor, RSL and others I just wanted to point to NorduGrids xRSL. It is (eXtended RSL) to it is mostly covered by RSL, however, there is some additions that I think could be usefull for JSDL: * runtimeEnvironment: Specifies specific software requirements on the cluster (like Gaussian, ATLAS and others.) It could though be added as an extention to JSDL. * nodeAccess: inbound|outbound essentially a light version of the Port sepecified above.
