ECDN or Enterprise Content Delivery Network is an organisation's globally distributed network of servers deployed for the purpose of faster content delivery by replicating the digital content strategically across all the servers in the ECDN. The digital content is then made available in many places and when a user accesses it, the content from the nearest server is delivered and served to the user. 


Without the ECDN, there are high chances of encountering the problems of network congestion and delayed delivery due to sudden and numerous requests from the users when they all try to access content at the same time.


VIDIZMO uses the ECDN to distribute live as well as on-demand video content. VIDIZMO allows organizations configure their own Origin and Edge servers for uninterrupted and fast live or on-demand streaming experience. 


By default, VIDIZMO provides four possible ECDN configurations to its customers:

  1. General Streaming Server Provider
  2. Wowza Streaming Server Provider (On-premise)
  3. Wowza Cloud Streaming Server Provider
  4. VIDIZMO Streaming Server Provider


This article discusses ECDN Node configuration of On-premise Wowza Streaming Server type. Users opting to utilize their on-premise Wowza CDNs as streaming endpoints can configure this option.


Before you Start

  • ECDNs can only be configured at the Account-level (main Portal), and are inherited from this main Portal to all the sub-portals where these servers can be utilized but cannot be added, updated or deleted.
  • Only users with Administrator or Manager roles can view, edit, delete and add ECDN Nodes in Streaming Server configuration.


Steps

Only Administrators and Managers of the main Account can configure ECDN nodes by following the steps:


1. From the Portal's Homepage

i. Click on the navigation menu on the top left of your screen

ii. Expand Admin tab

iii Click on Control Panel




2. From the Manage Portal navigation pane in Control Panel:

i. Select ECDN

ii. Select ECDN Nodes

iii. Select Add Server to add a new ECDN node




3. On the Add ECDN screen:

i. Select Wowza as your Streaming Server Provider

ii. Provide a Title for the Streaming Server

iii. Specify the Node Type that you wish to configure:

  • Creating a node of type Origin in case of serving on-demand content will essentially create it as an edge node because the uploaded content resides at the storage provider from where it is originally served. While in case of live streaming, you actually create an origin server since the encoder pushes the stream directly to this server
  • Select Edge to configure a server that locally caches content form Origin Server and serves them to the end-users

iv. If you selected Node Type as Edge in the previous step,  you will have to define its Origin server here from a list of available Origin servers, otherwise the field will be locked by default

v. You can Enable/Disable the use of this server by the toggle button

vi. Select the physical Location where you want the server to be based

vii. Select the Publishing Point Mode that needs to be configured for this streaming server. Choose from the following two options in drop-down:

  • PushIn case of push, it expects video stream to be provided to it and will primarily reroute it to other servers in the CDN
  • PullIf the stream is pulled, it will fetch video stream from a remote server

viii. Specify the Base Playback URL which refers to the URL from where it will be played back. In case of Wowza, mention URL of your Wowza Streaming Engine server along with its listening port. To learn more about ports used by Wowza for streaming, see: Wowza Streaming Ports.

ix. Provide the REST API URL, which is Wowza's REST API URL required to make API calls to your Wowza Streaming Engine. The format for the REST API URL is 


http://[yourWowzaServerBaseURL]:8087/v2/servers/[serverName]/vhosts/[vhostName]/


x. Enter the Username of your Wowza account

xi. Enter the Password against the username of your Wowza account

xii. Enter the shared path of your content storage where you wish to save the recording of your live stream content as Recording Root Path. If you enable recording against Wowza streaming server's publishing point, this path shall be used to save your recorded content for on-demand playback.

xiii. Specify the Server Type based on the type of content that will be served through this server. The options available are:

  • On DemandFor on-demand streaming of content
  • LiveFor live streaming of content
  • Live and On DemandFor both live or on-demand streaming

xiv. Click on Save to save your ECDN node




A notification will appear stating Streaming Server Added Successfully.
