Software Product Offering
In addition to system releases, Cisco currently offers several other types of software
products that enable the cable service provider to better manage their Digital
Broadband Delivery System (DBDS) networks:
•
•
Client Releases (Application Platforms) offer a bundled software package that
includes both the SARA and PowerTV
®
Operating System (OS). Client releases are
compatible with multiple system releases.
−
−
Client Maintenance Releases address a group of specific change requests that are
required before the next client release is available.
•
System Releases are software releases that are designed to improve or enhance the
functionality of the Digital Network Control System (DNCS). A system release can
be categorized as one of the following product types:
−
−
Major Releases and Minor Releases introduce new DBDS functionality while
fixing known issues in the network.
−
Service Packs are executable files that are an accumulation of fixed change
requests since the last major or minor release. After a service pack is issued for a
specific major or minor release, each subsequent service pack includes all
previously fixed change requests.
−
Patch Releases are a single, executable file that address an urgent customer issue
before the next system release.
−
Maintenance Releases incorporate patch releases and service packs into one
software release.
•
Headend Software Releases are software releases designed specifically for
headend components to enhance hardware functionality.
