ECDN licences

Q: Do I need a separate ECDN license for a redundant ECDN server deployment?

Yes, you will need a separate ECDN license to deploy a second ECDN server instance.

Note: We recommend that every location have at least two ECDN server instances for redundancy.

ECDN Management Portal

Q: I have a Streaming Manager / Streaming Manager for Enterprise account and login. Can I use the same credentials to login to the ECDN web portal?

Please open a support ticket, and mention the email addresses for the new logins.
