Real-time AI for Smart Networks – Building an OpenStack ‘Policy Brain’ | @CloudExpo #AI #Cloud

All of this data needs to be processed as part of a collective view indeed a collective intelligence of the network as a whole

Computer networkDCAE – Real-Time Analytics and Cloud Management
Another of the main foundations of the AT&T Domain 2.0 program is the ‘DCAE’ framework: Data Collection, Analytics and Events. In short their Big Data platform for enabling smart management.

“In the D2 vision, virtualized functions across various layers of functionality are expected to be instantiated in a significantly dynamic manner that requires the ability to provide real-time responses to actionable events from virtualized resources, ECOMP applications, as well as requests from customers, AT&T partners and other providers.

In order to engineer, plan, bill and assure these dynamic services, DCAE within the ECOMP framework gathers key performance, usage, telemetry and events from the dynamic, multi-vendor virtualized infrastructure in order to compute various analytics and respond with appropriate actions based on any observed anomalies or significant events. These significant events include application events that lead to resource scaling, configuration changes, and other activities as well as faults and performance degradations requiring healing.

The collected data and computed analytics are stored for persistence as well as use by other applications for business and operations (e.g., billing, ticketing).

More importantly, DCAE has to perform a lot of these functions in real-time.

This real-time ingredient is the secret sauce, as telcos begin establishing the platform for a monumental shift of all IT to a Cloud-enabled real-time mode, not just telecoms.

A&AI – Active and Available Inventory
Defining how this will integrate with their existing legacy OSS platforms to achieve this real-time capability is ‘A&AI’ – Active and Available Inventory:

“A&AI is the ECOMP component that provides realtime views of Domain 2.0 Resources, Services, Products and their relationships. The views provided by Active and Available Inventory relate data managed by multiple ECOMP Platforms, Business Support Systems (BSS), Operation Support Systems (OSS), and network applications to form a “top to bottom” view ranging from the Products customers buy to the Resources that form the raw material for creating the Products.

Active and Available Inventory not only forms a registry of Products, Services, and Resources, it also maintains up-to-date views of the relationships between these inventory items. To deliver the vision of the dynamism of Domain 2.0, Active and Available Inventory will manage these multi-dimensional relationships in real-time.”

Policy Brain

All of this data needs to be processed as part of a collective view indeed a collective intelligence of the network as a whole, and AT&T describe how they intend to build a “Policy Brain” for this purpose, setting the scene for an exciting exploration of this capacity evolving through AI techniques.

“D2 Policy will utilize rather than replace various technologies; examples of possible policy areas are shown in the following table. These will be used, e.g., via translation capabilities, to achieve the best possible solution that takes advantage of helpful technologies while still providing in effect a single D2.0 Policy “brain”.”

achieved through uniting:

  • Policy standards, like XACML, TOSCA and YANG
  • Implementation technologies – The Openstack policy modules like Congress, Heat and OpenDaylight GBP
  • Programmed business rules – Via apps like Drools and Ruby
  • Integration with other systems, such as IDAM and the ‘Astra‘ security system, for processing security related events
