Optimize via different Client Characteristics

In this simple scenario, we want to apply different Client Characteristics for Video on Demand (VoD) requests, based on the Client IP associated with the request.

Overview

We'll be fielding requests to a single, secure property hostname, baseball-highlights-media.com for the VoD content. Several CIDR blocks will be called out to use specific Client Characteristics, while requests from all other client IPs will use what's set in the Default Rule.

For ease of use in this scenario, NetStorage is used as the origin for all requests.

Phase 1: Create the Property hostname

We need a new AMD property with one Property hostname for the distribution of content, and we'll be delivering the content via HTTP.

The steps that follow outline what you need to do to create the Property hostname for this use case.

  1. You need Standard TLS certificates set up for each property hostname. These can take a while to provision, so you should create them before you create the AMD property. You need to include your Property hostnames as a CN or SAN in each respective certificate: "baseball-highlights-live-media.com" for the live content certificate, and "baseball-highlights-ondemand-media.com" for the VoD content certificate.

  2. Create a new AMD property in ​Akamai Control Center​.

  3. Set up a Standard TLS Property Hostname to Edge hostname association for "baseball-highlights-media.com."

Phase 2: Add a new rule for specific Client IP requests

For certain requesting clients, we want to ensure delivery is quicker. So, we're incorporating this rule to target requests from various CIDR blocks to use specific Client Characteristics behavior settings.

  1. In the Property Configuration Settings click Add Rule.

  2. Ensure Blank Rule Template is selected and click Insert Rule.

  3. Click the gear icon in the New Rule and select Edit Name. Input the desired name (for example, "VoD Delivery Client IPs") and press Enter.

  4. Click Add Match and set the fields as follows:

    • Client IP
    • is one of
    • Select Items. Click this field and input a range of CIDR blocks that represent IP addresses in the desired geographic location.
  5. Click Add Behavior.

  6. Type "client" in the Search available behaviors field to filter results, select Client Characteristics, and click Insert Behavior. For this example, we'll set the options in this behavior to optimize the delivery of lower-resolution content as follows:

    • Client Location. Select the geographic region that best represents the CIDR blocks you set for the match criteria.

Phase 3: Configure the Default Rule

Now, you configure the Default Rule to handle all other requests, as well as settings you want to be applied to all requests. For example, we'll configure "NetStorage" as the Origin Server for all requests here. Access it and set the use case-based behaviors here as follows:

BehaviorOptions
Origin Characteristics

Set the following options:

  • Origin Location. Set this to the geographic location that corresponds to the NetStorage Account you set in the Origin Server behavior.
  • Authentication Method. Akamai Origins - Auto, Others - None
Segmented Media Delivery Mode

Set the following options:

  • Mode. On Demand
Content CharacteristicsSet these options to best fit the VoD content you're delivering to your end users, to optimize its delivery. See Content Characteristics and AMD for complete details on this on this behavior.
Client Characteristics

Set the following options:

  • Client Location. Select the geographic region that best represents *all other* clients that will be accessing the VoD content.

What happens next?

First, you need to complete creation of the AMD property, optionally test it, and finally promote it to production for use.

Once live in production, request logic for your content works as follows:

  • A request to http://baseball-highlights-media.com from within a specified CIDR block. The VoD Delivery Client IPs rule exists last in the property, so it's checked first. Since the request originated from an IP address in a CIDR block named in this rule, its Client Characteristics setting is used. The Default Rule applies to allrequests, so its remaining use case-based behavior settings are used.

  • A request to http://baseball-highlights-media.com from outside the specified CIDR blocks. The Client Characteristics setting in the Default Rule is used for these requests. And, all of the remaining use case-based behavior settings are also applied.

👍

You could implement multiple instances of the "VoD Delivery Client IPs" rule (to a maximum of 6) for other geographic regions, and add more CIDR blocks to further expand this scenario.
