The move to highly virtualized data centers and cloud models is straining the network. While traditional data center networks were not designed to support the dynamic nature of today’s workloads, the fact is, the emergence of highly virtualized environments is merely exposing issues that have always existed within network constructs. VLANs, VRFs, subnets, routing, security, etc. have been stretched well beyond their original intent. The way these constructs are currently used limits scale, application expansion, contraction and mobility.

Network Management Needs New Ideas
As networks have grown, the industry has sought better ways in which to manage them at scale. Traditional network management systems are typically device-centric, particularly for network infrastructure. These systems take a top-down management approach and use a central server to push configuration into devices and to manage device state….
Stateless Transport Tunneling (STT)
STT is another tunneling protocol along the lines of the VXLAN and NVGRE proposals. As with both of those the intent of STT is to provide a network overlay, or virtual network running on top of a physical network. STT was proposed by Nicira and is therefore not surprisingly written…
