What is Software-defined WAN (SD-WAN)?

Software-defined WAN (SD-WAN) is a fundamentally different approach to WAN design that better deals with the performance, economic and security challenges and security challenges created by data traffic growth, cloud, mobility and the Internet of Things. 

SD-WAN introduces a powerful, software-based service layer that de-couples services delivered to users and sites from the underlying physical network connections. This means you can swap out expensive WAN connections, like MPLS, for lower-cost Internet. It ensures you're making the most use of all your capacity at any given time, providing you with significant choice and flexibility with your networks

Features & Benefits of NTT ICT's SD-WAN

GET MORE CAPACITY FOR YOUR MONEY

SD-WAN de-couples services delivered to users and sites from the underlying physical network connections. By swapping out expensive WAN connections for lower-cost Internet and Ethernet services, you make the most use of all your capacity at any given time, providing you with significant choice and flexibility with your networks.

Agility and Choice

ENHANCE NETWORK PERFORMANCE

SD-WAN gives you increased traffic visibility, which can be used to make smarter routing decisions based on specific application priorities, rather than broad traffic types. This reduces latency on business-critical applications and enhances the user experience.

Traffic Priority

DELIVERING IT FASTER TO NEW SITES

SD-WAN overcomes network bottleneck challenges by leveraging advanced analytics and network wide automation to speed up change processing. And by leveraging 4G LTE network connectivity in conjunction with zero touch provisioning, you greatly reduce the time taken to deploy new sites.

Faster Expansion

ENHANCE YOUR SECURITY

SD-WAN takes a "zero-trust" approach to security by encrypting all traffic by default. It simplifies traffic segmentation and ensures endpoint configuration is kept in sync through centralised administration. You can connect to more business partners and provide access to business applications for mobile workers with less risk.

Security Segmentation

IS SD-WAN RIGHT FOR YOU?

If any of the following situations describe you or your organisation then a SD-WAN solution will help.

  • We’re running SaaS or real time applications that are having performance challenges.
  • We can’t measure or guarantee application performance across our network.
  • We’re struggling to justify buying more comms capacity.
  • We have sites that we can’t afford to make highly available.
  • It takes too long to get network changes done.

 

TRANSPORT INDEPENDENCE

  • SD-WAN routers create an overlay network across available underlay network to provide optimal mix of bandwidth and cost
  • Underlay networks can be chosen from private MPLS or VPLS, Public Internet, or 4G mobile
  • SD-WAN overlay network supports Quality of Service for multiple traffic types

APPLICATION AWARENESS

  • Network is aware of applications that are traversing the network and where they are destined which enables smarter routing decisions
  • Network-wide SLAs can be set by and enforced on an application by application basis across SD-WAN

AUTOMATICALLY SECURE ENDPOINTS

  • Automatically encrypted with AES256 between all endpoints
  • Keys are automatically rotated at 2 hour intervals

NETWORK-WIDE SEGMENTATION

  • Traffic can be segregated endpoint to endpoint based on application, business or security rules to enhance overall security
  • Enables simple and secure connectivity to partner or 3rd party networks

CENTRALLY ENFORCED BUSINESS LOGIC

  • All SD-WAN endpoints are managed via a single pane of glass mangement system
  • Reduces the operational overheads of maintaining several individual sites and enables faster changes

CENTRALISED NETWORK SERVICES

  • Complex network functions like firewalls, load balancers and IPS can be easily inserted at strategic locations in SD-WAN
  • Network functions can be private or cloud-based
  • Simplifies network design and on-going management

Security and Accreditation

NTT ICT's strengths is our ability to deliver solutions which are compliant with ISM/PSPF and ISO/IEC 27001 environments.

All of our data centres are compliant with:

  • ISO/IEC 27001:2013 Information Security Management System;
  • ISO/IEC 9001 Quality Management System and
  • ISO/IEC 14001Environmental Management System


Our cloud and managed services are ISO/IEC 27001:2013 certified in the government data centres.
Government clearance: We operate platforms up to Protected level and maintain personnel who are baseline security cleared.

We can also provide a fully data sovereign service with 24x7 Australian based engineering, architecture and security services.

Why NTT ICT For Government

  • We can provide a fully data sovereign service with 24 x 7 Australian based engineering, architecture and security services.
  • NTT Group is financially stable and has a strong credit rating. Our Standard and Poor rating of AA is the highest of any telecommunications company worldwide and in a growth market we are making acquisitions, not being acquired.
  • NTT’s financial strength means that we can take on commercial risk to help you better manage day to day operations or transform your IT.
  • Every year NTT Group spend $2.5Bn on research and development across our Japanese research facility and our Silicon Valley based Innovation institute and in new product development within customer facing business units.
  • We are also recognised by the analysts as an industry leader
