Runtime bandwidth
demand (gigabits
per second)
• Helps guarantee predictable network
performance and fair sharing during congestion
• Supports bandwidth floors and bandwidth caps
• Helps enforce customer SLAs and maximum
pricing caps
• Sets QoS for virtual machine or traffic type
• Uses software built into Windows Server 2012 R2
or hardware capable of Data Center Bridging
(DCB) to assign minimum QoS settings
• Supports dynamic change of QoS settings
through PowerShell without any downtime

Virtual RSS (vRSS)
Dynamic VMQ (DVMQ)
Dynamic NIC teaming
• vRSS provides near line rate to a
VM on existing hardware,
making it possible to virtualize
traditionally network intensive
physical workloads
• Maximizes resource utilization
by spreading VM traffic across
multiple host and guest
processors
• Standard VMQ spreads VMs to
different cores statically
• DVMQ adds or removes cores
as the processing requirements
change
• Results in better processor use
for adaptive network workloads
• TCP streams or "flows” are
generally not continuous
• Groups of packets sent between
flows are called “flowlets”
• Dynamic load balancing detects
breaks in a flow
• Flows can be moved to other team
members on flowlet boundaries to
rebalance traffic
• Dynamic LBFO maximizes
utilization of teamed NICs
RDMA
SR-IOV
• Higher throughput with low latency
through offload
• Take advantage of high-speed networks
such as InfiniBand and iWARP
• Remote storage at the speed of direct
storage
• Compatible with SMB Multichannel for
load balancing and failover
• VM traffic bypasses virtual switch and
performs I/O directly to NIC
• Ideal for high I/O workloads that do not
require port policies, QoS, or network
virtualization enforced at the end host
virtual switch
• Reduce CPU overhead, network latency,
and increase throughput
How network virtualization works
• Overlays multiple virtual networks on
shared physical network
• Uses industry standard General Routing
Encapsulation (NVGRE) protocol
Problems solved
• Creates VM mobility across datacenter,
hoster cloud or Azure without network
constraints
• Provides ability to import customer IP
addresses and network topology
• Helps remove VLAN constraints
• Helps eliminate hierarchical IP address
assignment for virtual machines

Hoster wants to provide isolated networks for tenant
VMs with integral S2S VPN and NAT
Enterprises have virtualized networks split across
different datacenters or virtualized networks (NVGRE
aware) communicating to physical networks (NVGRE
unaware)
