Invoking the workflow and each service enabler has a cost.

Only want to invoke service enablers when it is really necessary, preferring fast-path routes if possible

Service Administration in Integra 3.x is split between:

- SPA workflow engine, service enabler filters

- Plan Management is a service enabler

In Integra 4.0 Service Administration

- Plan Management is no longer a service enabler

- Service Administration executes on the Request and the Response


Service Administration Overview

Service Administration provides you with the ability to enable/disable/modify services running on Integra based on:

- TCP flow information

- HTTP Request/Response transaction details

- Client session identity information, including information obtained from the PCC-A

Service Administration consists of

- Service Controls - A set of service switches with assigned values which are enabled when a service condition or condition group evaluates to true

- Service Conditions - Definition of Conditions that are evaluated within Groups

- Service Switches - The list of Service Control Switch Definitions. These are automatically populated at installation time for each service plugin installed.

Service Administration is a rules engine that generates service control settings

Control settings state:

- Which services should be applied

- How services should execute e.g. video optimisation level

Request / Response Headers


Service Conditions used to trigger services (when evaluated to true/conditions met) are:

- Interface Conditions

- URL Conditions

- User-Agent Conditions

- Request Header Conditions

- Response Header Conditions

- Data Dictionary Conditions

- Time Based Conditions

- Imported Service Control Conditions - Out of the box three

imported service conditions exist.

Service Conditions


A Condition Group is a compound expression

Each condition group operand is a Condition or another Condition Group (allowing another condition group effectively provides

parentheses around conditions)

Equivalent to Integra 3.x rules functionality

Configured under System Administration > Service Conditions > Condition Groups

Service Conditions Condition Groups


Service Switches

Service Switches definitions are held in the Service Administration > Service Switches

Value Added Services (Congestion Control) add to this canned data

Switch Name

Switch data type


Service Controls are a set of service switches with assigned values which are enabled when a service condition or condition group

evaluates to true

OAM administrators group service switches into one or more service controls where each service control can give each service switch a

specific value

Equivalent to Integra 3.x plans functionality

Each Control has a unique priority and a condition or condition group

- Priority is an integer value with lowest value being 1. The lower the

number the higher the priority

- Condition or Condition Group Name must evaluate to true to enable

the control which in turn turns on the service switches

Service Controls


Processing Logic

Service Administrator is invoked in the "fast path", ClientRequest and OSResponseevent of every request

Condition and condition groups configured for each Service Control are evaluated

Controls associated with each condition/condition group that evaluates to true are added to the service control list

All service switches from all active service controls are merged using defined combination methods:

Service Administrator exports the service switches in the ServiceControl data dictionary and these are used within Integra to control subsequent Service Enablers in the workflow



When creating configuration to apply to a service based on controls, start by considering:

- What service switches(s) do I want to apply?

- How will this interact with other service control configuration?

- In which condition group should I create the configuration?

What is the data type of the value of each service switch? i.e. Is the attribute value a Boolean, Enumeration or a String Data Type (reference to another

piece of configuration such as a header export table)

Configuring Service Administration


Deny Access to www.owmobility.com for Lumia800 devices

1. Choose Service switches

- AclAllow & AclDeny

2. Create URI lists

3. Setup User-Agent Condition

- Deny access for User Agent Mozilla/5.0 (compatible; MSIE

9.0; Windows Phone OS 7.5; Trident/5.0;

IEMobile/9.0; NOKIA; Lumia 800)

4. Setup Service Control with above configured service switches and

associated values (URI lists) and condition
