Fewer Ports for A/V in OCS R2

Fewer Ports for A/V in OCS R2

One of the things we did in R2 is review the edge topology and made significant changes in operation. We went from 20,002 inbound traffic from the Internet to 2 ports for inbound traffic. OCS provided UDP and TCP ports for Federated Audio/Video. We have re-engineered this sequencing to provide federated audio over 3478. Keep in mind if you plan to federate with another school and they aren’t running OCS R2 then you’ll have to use the OCS 2007 method as the old server won’t recognize the traffic change.

  • It would be terrific if inbound to DMZ 50000 and 59999 TCP and UDP were not required, but this seems to conflict with:

    If you look at Figure Mapping 9, it seems to show that this is still a requirement.  Is this right?

  • It doesn't conflict with the diagram on technet. You see that the 50K-59K requirement is optional and needed if you federate with campuses that are OCS 2007 not R2.
