Using TRILL, FabricPath, and VXLAN: Designing Massively Scalable Data Centers (MSDC) with OverlaysOver the next decade the number of servers virtual and physical worldwide 10 will grow by times. Meanwhile, the number of IT professionals in the world will grow by 1. Leaf1 L1 receives the packet and performs Layer-3 lookup for the destination 6. Leaf1 L1 adds the Layer-2 and the FabricPath headers and forwards the encapsulated frame across the Fabric, picking one of the equal cost paths available via the multiple Spines 7. If valid routing information for H2 is available in the unicast routing table, Leaf1 L1 adds the Layer-2 and the FabricPath headers and forwards the FabricPath frame across the Fabric, picking one of the equal cost paths available via the multiple Spines 7. H1 originates a packet destined to H3 MAC address 2. Leaf1 L1 adds the FabricPath header before sending the packet into the fabric 4.

Building on this foundation, they offer in-depth coverage of FabricPath: its advantages, architecture, forwarding, configuration, verification, and benefits in Layer-2 networks. It also presents three detailed implementation scenarios, each reflecting realistic data center challenges. In particular, the authors show how to integrate multiple overlay technologies into a single end-to-end solution that offers exceptional flexibility, agility, and availability. Sanjay K.

What You Will Learn In the modern data center, traditional technologies are limiting the speed, flexibility, scalability, and manageability of application deployments. There is emerging interest in the industry in overlay technologies, which may address some of these challenges. This document examines why the industry is moving toward adoption of network overlay technologies, and it describes the benefits and challenges of these technologies. Introduction Successful businesses rely on quick development of new applications, which requires data centers to be more efficient, scalable, and agile. The industry has been seeking ways to use virtualization technologies to offer these benefits, not only for computing and storage resources, but also for the network infrastructure. The adoption of server virtualization has been rapidly increasing throughout the industry, which has benefited data center administration as a whole, allowing greater flexibility and agility in the provisioning and placement of computing workloads. However, network connectivity has not kept pace with such innovations in the computing environment, still offering a rigid approach to provisioning transport services.
