Node 2.0 - Topics

Description of Node 2.0

Goals

Drivers for upgrading

Support for Node 1.1 and partner transition

Node 2.0 Enhancements

Technical changes in Node 2.0

Update on the current migration process

Node 2.0 Basics

Version 2.0 of the Exchange Network Node is the next generation of technologies and services that will power the Exchange Network.

Node 2.0 is basically a specification or technology change

Support for Node 1.1 and partner transition will continue

The Goals Create a flexible, extensible web service network

(SOA) that allows partners to easily discover and exchange arbitrary information from any point to any point reliably, and securely.

Create a framework that leverages current and future technologies, and meets both current and future data exchange requirements.

Even better Quality of Service

The Challenge Future Network business processes and technical

requirements need to be supported by the architecture

The technology landscape is still evolving rapidly.

Multiple operating platforms are supported.

Different visions and near term goals exist.

Node 2.0 Changes Three major changes to Node technologies

SOAP 1.2 – latest SOAP Version Doc/Literal WSDL

(Web Service Description Language)Messages become schema compliant

MTOM – Industry message attachment specification (Message Transmission Optimization Mechanism)

Changes primarily driven by vendor support issues Changes will be mostly transparent Node 2.0 can easily be adapted to inter-operate with

other Web services networks.

State Node 2 Flow Migration CDX Node was enhanced to support Node

2.0 specification

CDX ready to support Exchange Network National Flows for State migrations to Node 2.0 - September 2008

Coordinate transition to Node 2.0 Sept. 2008 - Sept 2010

All new flows will use Node 2.0 design

Expanding Node Server Capacity

Migration to 64 bit Operating System Extends server memory support from 4 Gigabytes to

Terabytes

Virtualization of CDX Architecture Simplifies expansion of server capacity Dynamically allocate CPUs, memory, virtual servers Failover, disaster recover Simplifies Operations and Maintenance

TRIME Test Deployment Status

Deploys on New 64 bit Blade Server Significantly expanded resources 64-bit CDX Node Server

Configured and running TRIME Scheduled for 4/6/2009 Firewall Rule Request Submitted Digital Certificate ordered

TRIME Production Deployment Deploys on New 64 bit Blade Server Significantly expanded resources 64-bit CDX Node Server

Begin configuration this week Scheduled for April 11, 2009 Firewall Rule Request Submitted Digital Certificate ordered

Node 2.0 – Better Stronger Faster!!

New Node 2.0 Exchanges

Node to NodeNode to Node

Client to NodeClient to Node

Web Client to ClientWeb Client to Client

Service Discovery 2.0 (ENDS 2.0) Exchange Network Discovery Services 2.0

Automatically collects and updates Network meta data repository

Improves Information Access

Supports User Friendly Tools

Simplifies Administration

Security 2.0 Network Authentication and Authorization Service

NAAS 3.0 = Node 2.0 Security Message Support + Enhancements

Network Node v2.0 will use NAAS 3.0 services.

NAAS 3.0 will not be compatible with NAAS 2.0 due to protocol changes.

NAAS 3.0 will be deployed in parallel to NAAS 2.0. There will be no impact to the existing Node 1.1 services.

Existing user accounts are valid to both NAAS 2.0 and NAAS 3.0. (accessed from common repositories)

Quality Assurance 2.0

XML parsing and extended business rule validation

QA 2.0 = QA + Node 2.0 Message Support + Enhancements

New 4 CPU 64 bit server with 4 times as much memory

Looking into server virtualization for easier capacity expansion

Node 2.0 Publishing

Node 1.1 Focused on Basic Data Submissions

Data Publishing is the Focus for Node 2.0.

Data Publishing is Essential for Leveraging all of the Power of our Network SOA .

Publishing and Syndication Services 2.0

New Publishing services that support the secure exchange and syndication of any data

Totally configurable – Easily add new dataflows / information

sources Configure new RSS/ATOM Feeds in minutes

Used for the Agency Recovery.Gov interface Flexible and extensible Supports Web Service and Browser based

submissions Supports embedded and linked syndication

Basic Syndication Workflow

Content providers describe and submit documents: Browser Client Node

Services store metadata and data or pointers to the data in a repository and create syndicated feeds automatically

Users subscribe to the new Feeds or Channels

The subscriber uses a Reader or a Browser to search, filter, and read the RSS/ATOM summary data locally

Users get security challenge when they drill down to actual data

Node 2.0 Interoperability Capabilities

Enriched Extensibility: Allows partners to add any local services as needed

Support for external web services and other networks such as CDC, Homeland Security etc.

Dynamic Discovery: A framework for discovery of Services and binding to them .

Extending Network Capabilities High flexibility:

Remove data format limitations and exchange barriers Allow flowing binary data and XML data in both directions. Enhance the scope of exchanges

(user-node, node-node, user-user).

Enriched extensibility: Allows partners to add other services as needed (not just

data services) and be able to leverage external web services.( work with other networks).

Extending Network Capabilities

Improved Quality of Services: Real-time status, status notification, transaction tracking and management.

More Support for real time services Dynamic Discovery: Provide a framework for discovery

of node capability at runtime. Allows point-2-point or person-2-person secure data

exchanges. Opens the door for ad hoc dataflows that exchange

emergency data

Major Node 2.0 Features

Query paging/chunking and results compression.

Support for outgoing delivery of binary data.

Name-based parameters for Query, Solicit and Execute.

Allows various types and encoding of parameters.

Notification/Recipients Enables Point-2-Point and Person-2-Person Exchanges

Major Node 2.0 Features - 2

Execute method. Allows nodes to support additional web

services Extends Network access to all external web

services (proxy).

Node self-description and discovery Nodes can publish sufficient information

for run-time binding.
