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?
No. Today they are separate applications and ECDN requires its own unique login. Your IBM sales representative will create the account that will provide access to the ECDN Management Portal.
Q: How can I add additional logins to my ECDN account?
Please open a support ticket, and mention the email addresses for the new logins.
ECDN servers
Q: What are the file sizes of the ECDN virtual appliance images?
- VMware ESXi: 0.7GB
- Microsoft Hyper-V: 3.2GB
Q: What version of ECDN server addresses the Meltdown and Spectre security vulnerabilities?
ECDN server version 2.0.201801231516697504 contains all identified Ubuntu 16.04 LTS operating system fixes up until January 23, 2018 to address these vulnerabilities. As new fixes are made available, we will include them in subsequent releases.
Exposure to ECDN servers is minimal to start with, as it runs as a guest virtual machine. This version addresses all security gaps known to us. You may contact ECDN customer support and request for all your existing servers to be upgraded to the latest version. Most upgrades can be completed within a day. We will do our best to meet all upgrade requests asap.
Host hypervisors are more vulnerable. It is important that you immediately take action to ensure that all hypervisor vendor specified patches are installed as soon as possible.
If you are creating new instances of ECDN servers, then download the latest version and use it for creating the new VMs.
Q: What DNS servers can I use while configuring ECDN servers?
IBM Video Streaming player communicates with ECDN servers over HTTPS using their FQDNs (fully qualified domain names). It is required that these FQDNs be resolvable to their corresponding IP address, via a DNS server. You may use the DNS server that is prescribed for your organization. If there is none, then you may use a public DNS servers like 8.8.8.8 and 8.8.4.4 that are owned by Google, or DNS server 9.9.9.9 owned by Quad9.com.
Q: Can I use the same ECDN edge server to support players from two different internal networks (e.g. intranet and guest network)?
Yes. One ECDN edge server can be used to support traffic from multiple internal networks. Just make sure, the player clients have connectivity over these internal networks to the ECDN edge.
Q: What is the recommended configuration for the ECDN edge server virtual appliance?
Configuration for the ECDN edge virtual appliance depends on the number of viewer players clients that are expected to connect.
For more details, see ECDN system requirements.
Q: How many viewers can one ECDN instance support?
The number of viewers one ECDN server instance can support depends on several factors: network connectivity, hardware configuration, number of concurrent video streams and their quality.
