NetLord: a scalable multi-tenant network architecture for virtualized datacenters
Abstract
Providers of “Infrastructure-as-a-Service” need datacenter networks that support multi-tenancy, scale, and ease of operation, at
low cost. Most existing network architectures cannot meet all of
these needs simultaneously.
In this paper we present NetLord, a novel multi-tenant network
architecture. NetLord provides tenants with simple and flexible
network abstractions, by fully and efficiently virtualizing the address space at both L2 and L3. NetLord can exploit inexpensive
commodity equipment to scale the network to several thousands
of tenants and millions of virtual machines. NetLord requires
only a small amount of offline, one-time configuration. We implemented NetLord on a testbed, and demonstrated its scalability,
while achieving order-of-magnitude goodput improvements over
previous approaches.
