Designing A Data Centre Topology Architecture

Our IP Network will be simplified to strip out cost and complexity by taking out layers of switching and routing and moving to a robust multi-tenanted network supporting multiple lines of business. Also our Distributed Cloud vision will require that we implement new infrastructure (NFVI) in a number of our core, edge and access locations. To support this, we will create a Data Centre topology architecture that lays out which locations will be upgraded to support what sort of virtualised network functions. Refer to Figure 5 - IP Network Simplification example below. This Network Data Centre topology architecture will also need to be supported by a new IP network topology and exchange / access location (base station) topology. Refer to…show more content…
• Be as simple and lowest cost as possible – we should be able to decouple the data growth from the cost to support it with a simple and scalable IP network architecture. • Resilience – should be designed for high availability of the distributed cloud services that it carries and with “zero-downtime”. • Automation – should support SDN for automated per minute consumption of capacity and automated failover to alternative paths. • Scalability – support future growth without the need to redesign – ie by adding additional nodes with a simple building block approach 9.1.2. IP and Optical Networks implementation architecture options Simplification of our IP networks will be needed to contain costs and data grows and to make the task of SDN control manageable as SDN is implemented. Figure 5 - IP Network Simplification example We will create a network locations topology plan that will lay out the locations where we will support distributed cloud compute and storage. The IP and Optical networks will need to be designed to support that plan. Figure 6 Example Core and Edge locations topology Leaf-spine architecture is an alternate to todays wide area network three-layer core/aggregation/access network architecture. It is used in Data Centres to provide resilient and non-blocking networking to compute and storage resources. Figure 7 - Leaf-spine
