Abstract:
   This document describes how a multi-tenant data centre operator can
   isolate tenants from network performance degradation due to each
   other's usage, but without losing the multiplexing benefits of a LAN-
   style network where anyone can use any amount of any resource.  Zero
   per-tenant configuration and no implementation change is required on
   network equipment.  Instead the solution is implemented with a simple
   change to the hypervisor (or container) on each physical server,
   beneath the tenant's virtual machines.  These collectively enforce a
   very simple distributed contract - a single network allowance that
   each tenant can allocate among their virtual machines.  The solution
   is simplest and most efficient using layer-3 switches that support
   explicit congestion notification (ECN) and if the sending operating
   system supports congestion exposure (ConEx).  Nonetheless, an
   arrangement is described so that the operator can unilaterally deploy
   a complete solution while operating systems are being incrementally
   upgraded to support ConEx.
