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.
