The authors begin by reviewing today's fast-growing data center requirements, and making a strong case for overlays in the Massive Scale Data Center MSDC. Building on this foundation, they offer in-depth coverage of FabricPath: its advantages, architecture, forwarding, configuration, verification, and benefits in Layer-2 networks. Through examples, they explain TRILL's architecture, functionality, and forwarding behavior, focusing especially on data flow. It also presents three detailed implementation scenarios, each reflecting realistic data center challenges.

QFabric is a proprietary technology proposed by Juniper Networks. In contrary to open standards such as OpenFlow , QFabric is regarded as a vendor proprietary approach. For data center architecture, QFabric creates a single logical switch that connects the entire data center rather than tiers of multiple access aggregation and core switches. The reason why this can improve performance is that, instead of going through multiple tiers of switches in a traditional network, packets only get through the infrastructure in a single hop, so this can reduce the delay significantly. In QFXG QFabric System, although it supports up to 6, 10GbE ports, by connecting all nodes in a full-mesh topology, it can achieve an average port-to-port latency of 5 microseconds.

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.
