Carrier Grade Quality

AdvOSS platforms offer carrier grade quality for its products. These quality benefits are achieved through a combination of:

0Enabling Technologies0Software Architectures

Enabling Technologies

These are a range of technologies that are used by AdvOSS in its platforms to achieve quality objectives. Many of these technologies are developed by AdvOSS.

Others are third party technologies or features used by AdvOSS to achieve its quality ends.

1. AMPS

AMPS (Asynchronous Middleware of Parallel Systems)It is an AdvOSS own technology. It is a middleware that is internally running on a high performance asynchronous processing engine and offers many aspects of reliability, efficiency and others. Details can be found at http://OpenAMPS.org

http://openamps.org/

2. Protocol Stacks

AdvOSS has its own developed protocol stacks that are built on top of AMPS. These stacks are available for the following protocols:0SIP0Radius0Diameter

Service Delivery Platform

SIP Radius

3. Service Delivery EngineAdvOSS SDE is a Service Creation Engine with a service execution engine that allows high speed execution of work flows. SDE is based on industry standard CCXML (Call Control XML). We have made proprietary extensions to it and call it SCCXML (Service Creation and Control XML). Details can be found at http://sccxml.org

5. Heart-Beat

AdvOSS Heart-Beat is a High Availability framework that exposes Virtual IP connections upon identical servers and the heart-beat mechanism allows an automatic IP take over from one server to the other when one server goes down.

6. Packet Router

Packet Router is yet another AdvOSS technology that is based on AdvOSS’ own protocol stacks and AMPS. It allows load distribution and dispatching of layer 7 packets at high speed. A layer 4 and a layer 7 dispatcher together achieve highest speed load distribution among serving nodes.

9. Orchestrator

Orchestrator is yet another AdvOSS technology part of AdvOSS Provisioning Engine that allows work flow execution through any external third party work flow execution engine. Following languages are supported out of the box:0Xproc (a w3c standard for pipelined workflows)0Groovy Pipelines (Proprietary language)0SCCXML (Through AdvOSS SDP)

Software Architectures

In addition to the above mentioned enabling technologies, AdvOSS uses many aspects of software architecture and design in its products to achieve quality objectives.

1. Layered Architecture

AdvOSS products are designed in layers which typically are:0Dispatching0Applications

0 Processes0 APIs

0Database Processing

Dispatcher / Packet Router

Client Requests

Application Nodes

Database

Database Abstraction

2. Work Flow driven processes

All AdvOSS Applications are written in work flow languages which are open source and work on a work flow processing engine.

3. Policy Driven APIs

All AdvOSS APIs are transactional in nature and embed all the business logic in them. To keep them compliant with changing business rules, they all designed to work with Policy Servers that allows realization of company policies into the APIs.

Business Benefits

Above mentioned enabling technologies and architectural aspects are used to derive multiple business benefits.

1. High AvailabilityAdvOSS High Availability framework allows the system to continue functioning in the condition of a hardware or network failure

Scenario 1: Failure of Application NodeThe Packet Router sends the packets to other nodes for processing

2. Scalability

AdvOSS Scalability Architecture allows a Service Provider to start small and grow as much as needed.Packet Router along with the dispatcher / serving node model allows for addition of new serving nodes on the fly for applications.For databases, multi-master deployment model allows for scaling out and adding new nodes for further processing.

Application Node ScalabilityPacket Router distributes the load onto multiple Application Nodes. Application nodes can be added as many as needed.

Packet Router ScalabilityPacket Router is very efficient load distributor and works on Layer 7 load balancing. If needed, a Layer 4 load balancer can be added and multiple Layer 7 packet routers can be added

Database ScalabilityMore nodes can be added in the multi-master ring for distribution of read loads onto multiple database server.

3. Redundancy

AdvOSS Redundancy Architecture allows a Service Provider to keep extra resources either in load-sharing or hot-standby mode and use them in case of failures

Application Node RedundancyPacket Router keeps all application nodes in active load-sharing.

Packet Router Redundancy:AdvOSS Heart-Beat framework allows a Service Provider to keep two packet router nodes where one stays as a hot-standby and assumes the load on failure of primary node.

Database Redundancy:Multi-master Replication allows to keep extra databases fully ready with latest data in sync. In case of failure, such extra database nodes are used by DTMS automatically
