Types of Licenses

You must obtain a license for the SDX software from Juniper Networks Customer Support. Juniper Networks provides two mutually exclusive types of licenses for the SDX software:

• Pilot license - limits the number of concurrent sessions on an SAE. The number of sessions used at any one time cannot exceed the number permitted by the pilot license. Use the pilot license for field trials of the SDX software.
• Production license - limits the number of active service sessions.We refer to these licenses as service session licenses or server licenses. When an SAE requests a license lease, the SDX license server computes what the total license consumption will be if the request is granted and compares that value to the limit specified in the license. The license server grants the lease if the value is less than the limit. If the request puts the total over the limit, then the request is granted only up to the limit. When the license limit is reached, further requests are denied until a lease becomes available. Use the production license for a production implementation of the SDX software.

In earlier releases of the SDX software, the production license limited the capacity of the entire network under SAE management and optionally specified the maximum number of value-added services that were concurrently available to be activated by subscribers, an expiration date, or both. We refer to these licenses as capacity/service licenses.

The SDX software stores licenses in a master directory to which all SAEs have access. If you have both a production license and a pilot license, the SDX software enforces the production license.
