Current Set-upCurrent Set-up

Low or no data exchange between various departmentsComputerization without interoperability

If automated various departments may use different technologies, platforms, languages for developing their applications which may become a limiting factor in data exchange between departments

Data exchange in paper formatEach department has a separate front-end

Citizen needs to visit and remember multiple locations for their various requests. No unified face of government

What Is SSDG?

SSDG is a message X-change

Interoperable –

Helps any Service Access Provider (SAP) to Communicate with any Service Provider (SP) with appropriate authentication

IIP/IIS standards are developed to achieve this

XML based data

Secure

Authentication between SAP and services is achieved through mapping

PKI support

XML signature

Cont……

24 X 7 availability

Decouples front end from the business logic

Useful for joint services

No vendor locking

Designed for easy programming interface

Facilitate easy integration with SSDG

Ensure compliance to IIP (Interoperability Interface Protocol) and IIS (Interoperability Interface Specifications) messaging standards available in Java and .NET used by SSDG

Two types of connectors

Generic Connectors

Application Specific Connectors

Working with ConnectorsWorking with Connectors


Application Specific -SAPApplication Specific -SAP

Request from SAP to avail SP service will be sent through SSDG.Application Specific Connector will take the data from SAP and will convert the request as per the format understood by SP.Application specific Connector will use the API’s of Generic Connector to send the payload as per the IIP/IIS standards to the SSDG.Application Specific Connector will be developed by IAs.


Generic -SAPGeneric -SAP

Purpose of generic connector is to interface with gateway for standards based messaging communication.

C-DAC will be providing Generic Connectors.

Generic connectors are available in Java,. NET and php.


Generic -SPGeneric -SP

Purpose of generic connector is to check whether the message sent by SSDG is valid or not.

If the message sent is valid ,it passes the message to Application Specific Connector by extracting the payload and other necessary details.

If the message is invalid then it sends back the message to SSDG by populating necessary error codes.

C-DAC will be providing Generic Connectors.

Generic connectors are available in Java,. NET.


Application Specific -SPApplication Specific -SP

Based on the payload and details provide by generic connector, application specific connectors will send the request to SPs whose services are requested.Application specific connector will send back the necessary response to SAP through SSDG.Application Specific Connector will be developed by IAs.

Service Level of SSDGService Level of SSDG

Supports 50/100/250 messages per second (based on the BOM purchased by State)

95% of the transactions will a response time of 3 seconds else it will constitute a violation.(Note: Performance may vary depending on the Hardware Components used.)

Roles and Responsibilities Roles and Responsibilities of C-DAC of C-DAC

C-DAC will provide SSDG software product

C-DAC will also provide the optimized SSDG software stack containing:

Operating System

Application Server

RDBMS


25

Roles and Responsibilities Roles and Responsibilities of C-DACof C-DAC

C-DAC will provide necessary patches, service packs and upgrades of SSDG over a period of 1+3 years

C-DAC will provide technical support for SSDG product and the optimized Stack

C-DAC will provide the training to the Implementation Agency (IA) and the state personnel.


26

Roles and Responsibilities Roles and Responsibilities of Stateof State

State needs to sign an End User Licensing Agreement (EULA) with C-DAC before deploying the SSDG product.

It is recommended to get the deployed SSDG solution certified by STQC as per ISO 20000 and 27001 standards.

States should purchase the hardware subject to compliance with the Bill of Material (BOM) provided by C-DAC.
