While private layer 3 MPLS IPVPN may be at the core of you Enterprise network requirements, hybrid architecture is often the result once requirements are taken into account. Data centres may require layer 2 connectivity to extend LAN to LAN connectivity and DR (Disaster Recovery). In cases where your data centre locations cannot be connected via dedicated fibre (SHDS), VLL (Virtual Leased Line) pseudo-wire connectivity will bridge the gap of greater distances.
Cloud applications and performance will need to be considered from the perspective of user profile and whether or not the traffic originates from the Internet (remote user) or from private based corporate connectivity. In many respects, the cloud is driving the resurgence of Internet based VPN, either based on devices such as iWAN SD-WAN or straightforward DWVPN.
With the above said, cloud capability is available for private MPLS IPVPN via services such as Microsoft ExpressRoute for Azure.
Examples of Cloud connectivity include thin client, CRM, voice and video.
For any large Enterprise business, the presales element becomes intrinsically linked to the success of your WAN connectivity project. While providing simple circuit bandwidth and associated managed services is good for setting budgets, analysing your application and user flow is key to overall alignment of design vs. business enablement.
Our presales workflows look at a subset of users to understand how they interact with the network from the perspective of location, resources, application type and their importance to the business.
Dedicated resources which understand the end to end solution are provided in the form of technical design authority, project and service management. End to end communication between each department results in a much more focussed set of requirements.
Design simplicity is another important tool. Some level of complexity is a given in large MPLS IPVPN WAN solutions, but the more logical simplicity you can create with your network infrastructure design, the better positioned your business will be able to respond to changes when network requirements occur.
Managed Services offer additional support outside of IPVPN MPLS circuit connectivity. The BT product portfolio includes Cisco, Checkpoint or Palo Alto Firewall security, Cloud access including Microsoft ExpressRoute, Office 365, Managed LAN, SD-WAN, IPSec DWVPN, Hosting, DataCentre, 3G /4G fast start and failover.
During organic growth or decline, you might need to add or remove portions of your infrastructure. A logically simple design will help you better understand and account for the effects these changes will have on the network as a whole. Modularity and the alignment between network simplicity and complexity critical design concepts.
The type of network design for large businesses should take into account how traffic needs to flow within the company— how each user and location communications, how do you serve your customers? What applications are in use and how critical are they? Where is fast-start access needed?
The correct design can make business processes simpler and improve communication within every area of your Enterprise. Large businesses must have at least a high-level understanding of your organisation processes and workflows before contemplating MPLS VPN network design.
Additionally, it will help IT teams to understand whether any changes are in process or being planned/considered.
