GLOBAL AND UK BT CONNECTIVITY

BT SD-WAN SERVICES

FEATURING CISCO IWAN
X
We’ve aligned our BT Premier Partner status to bring together the huge logistical Internet capability of BT UK and Global Services Internet, Private WAN services (MPLS, VPLS, SHDS) with Cisco iWAN to create a single backbone Managed Global or UK SD-WAN proposition.
BT connectivity aligned with Cisco iWAN managed services offers organisations solution based hybrid architectures via one single platform.
  • More usable WAN bandwidth - a lower cost by utlising multiple connectivity types
  • No sacrifice of performance due to a more granular sophisticated software based configuration
  • Transport independence
  • Intelligent Path Control
  • Application Optimisation
  • Secure Connectivity


Our SD-WAN group has several decades experience designing Global and national WAN services. In 2016, we set up a specific team exclusively focussed on SD-WAN services across the BT Internet and MPLS backbone with Cisco iWAN capability.

We help account manage businesses looking to gain a competitive advantage by implementing SD-WAN services to add speed, agility and responsiveness to their business and customers.

Our goal is to educate first and foremost. Our free SD-WAN workshop offers insights into the benefits, features, opportunity, risks and pitfalls associated with buying software-based WAN technology.

The Art of SD-WAN Procurement Workshop.

A free 2 hour session where Techtarget.com writer Robert Sturt will walk you and your team through the latest thinking behind aligning your business requirements to SD-WAN services.

The sessions are free and available at your office across the UK.

What will we learn? 

MPLS vs. VPLS and why SD-WAN is transport independent.
Aligning your applications to SD-WAN technology.
Security across multiple connection types.
Application acceleration and QoS Challenges for Global vs.
UK business, defining an SD-WAN SLA.

AN OVERVIEW OF THE SD-WAN PRODUCT

1

Why SD-WAN managed services?

Cisco iWAN aligned with BT allows an Enterprise to deliver a standardised level of performance via intelligent software based technology regardless of the underlying interface or connectivity.

The primary method of cost saving is to use Internet connectivity.

With this in mind, careful consideration must be given to application performance vs. traffic paths and corresponding latency and jitter. Our technical account managers use a 25 point process to identify your specific requirements allowing us to create hybrid WAN designs incorporating all circuit types where appropriate, e.g. MPLS, VPLS, the Internet, dedicated private fibre and remote access Broadband.

Our Cisco and BT proposition provides an architecture and capability to supply more usable bandwidth at a lower cost base without sacrificing security, traffic performance or reliability.

SD-WAN Transport Independence.

Cisco DWVPN (Dynamic Multipoint VPN) allows transport independence providing a consistent environment for routing. In other words, regardless of your access medium (The Internet with Broadband, 3G, 4G, MPLS, VPLS), your topology and routing configuration remains constant.

Where SD-WAN differs vs. MPLS and VPLS is the ability to leverage software to sense when conditions occur.

As an example, a remote user working from a hotel with poor bandwidth and latency will benefit from clever software-based technology to make the best of their connection.

Intelligent Path Control

Whether or not your team is familiar with routing protocols, the key take away is this - network path calculation varies depending on the deployed protocol.

Routing protocols do not understand packet loss, delay, jitter or link/circuit utilisation when calculating path routes.

The result could be an unstable path for your application causing issues we’re all familiar with across networking. While Cisco IP SLA will measure path performance, the actual route remains unmodified.

We think of the Internet as being a mostly inferior network to layer 3 Private MPLS, but the reality is that most public networks are well scaled and utilise the traffic engineering properties of the MPLS protocol.

SD-WAN with PfR (Performance Routing) supports intelligent path control based on the application class. If a path becomes unstable, alternative connectivity is selected for the application to improve performance until the original path properties improve.

In scenarios where bandwidth becomes congested, further connectivity will be used if available to compliment primary connectivity.

This feature should not be understated. With traditional WAN failover, primary circuits often remain up when services become degraded. The failover state is binary - unless the primary is hard down, the failover circuit remains unused.

Application Optimisation.

Bandwith, path and latency, congestion and application behaviour are all variables when discussing how SD-WAN supports application optimisation.

Cisco WaaS and Akamai Connect offer the capability to overcome the afore mentioned variables as an end point transparent technology.

Cisco WAAS looks for repeating patterns in data - if your business sends the same content with slight changes, the WAAS end-point will locally duplicate the data. This technology is primarily data caching, making intelligent use of your WAN. Chatty application traffic (TCP) is improved via local acknowledgments.

Secure Connectivity.

The concepts behind Cisco iWAN are comprehensive in scope consisting of Zone-based Firewall services and Cloud Web Security. 

iWAN brings stateful packet inspection, capable of examining OSI layers 4 through to 7 of your network packets.

A stateful firewall can detect DDOS (Distributed Denial of Service) intrusions.

Zone based firewalling further decreases costs as there is no need for secondary devices when segmenting your network infrastructure.

Cloud usage is at the forefront of network security policies with zero-day threat and malware protection without the need to procure further dedicated hardware.

Leveraging SD-WAN for Cloud services.

One of the reasons sited by proponents of SD-WAN for the decline of MPLS services is sited as cloud applications via Internet-based access. Think salesforce.com, Amazon, Microsoft and Google for a start. And, changing your vendor to a cloud-based model is a much simpler procurement exercise vs. Capex based on-site hardware.

The same applies to SD-WAN services, once bought into the capability, any connection is supported.

If applications reside on the Internet, layer 3 Private MPLS is viewed as restrictive since interconnects or public IP breakout is required to access resources. Software WAN allows the corporate network to communicate securely but also to access cloud applications regardless of transport as mentioned earlier.

The Internet is a much more scaled platform when compared to even a few years ago due to the massive expansion of Ethernet. With connectivity to cloud providers, users and employees experience a standard level of service whether they’re working from an HQ, branch or home.

The concept of Voice, Video and Collaboration with SD-WAN services

The benefit of consolidating voice and data into one circuit is familiar to the majority of IT Managers. Converging applications has obvious cost savings together with the simplification of infrastructure.

SD-WAN is enabling the Enterprise to fully leverage sophisticated feature-rich collaboration via cloud capabilities. Services such as Cisco Webex provide virtual meeting capability by combining voice, video and desktop sharing. Software WAN technologies further enhance access to virtualised cloud services for your users regardless of location. 3G and 4G secured Internet, Broadband or even the Hotel Wifi.

While SD-WAN does not offer end to end QoS (Quality of Service), the features offer traffic prioritisation and state sensing meaning users are aware their current connection may not support delay sensitive applications.

SD-WAN and BYOD (Bring your own Device).

A main headache for IT staff when dealing with multiple employee devices is associated with management.

BYOD brings some significant benefits.

The benefits to the users are higher employee satisfaction which in turn has an advantage to the business with better productivity and cost savings.

As BYOD hardware is not typically centrally managed, an SD-WAN client can apply a standardised pre-determined level of security across multiple Internet connectivity types.

What if we require SD-WAN carrier diversity?

Further diversity is available via additional partnerships where needed. 3rd party Internet with 3G, 4G and leased lines are options for integration.

Single or multiple carrier diversity.

While our primary backbone choice remains BT Global and UK Services, we have a range of other options providing high availability.
