Routing-as-a-Service (RaaS): A framework For tenant-directed route control in data center

In a multi-tenant data center environment, the current paradigm for route control customization involves a labor-intensive ticketing process, in which tenants submit route control requests to the landlord. This results in a tight coupling between tenants and landlord, extensive human resource deployment, and long ticket resolution time. We propose Routing-as-a-Service (RaaS), a framework for tenant-directed route control in data centers. We show that RaaS-based implementation provides a route control platform for multiple tenants to perform route control independently with little administrative involvement, and for the landlord to set the overall network policies. RaaS-based solutions can run on commercial off-the-shelf (COTS) hardware and leverage existing technologies, so it can be implemented in existing networks without major infrastructural overhaul. We present the design of RaaS, introduce its components, and evaluate a prototype based on RaaS.
