Customer problems with networking
Advancing Software Defined Networking Customer problems with networking BACKGROUND Network virtualization lags behind compute and storage Administration within the data center may be soiled THE CHALLENGES Physical network configuration is not flexible Workloads tied to underlying hardware configurations Configuration changes are manual and cumbersome Diverse network infrastructure requires vendor-specific management and control Greater VM mobility and density difficult to achieve VLAN tags Aggregation Switches ToR ToR VMs

Software Defined Networking – our approach
Enables software to dynamically manage the network by: Enabling integrated policies that span physical and virtual networks Abstracting workloads from the physical network Controlling datacenter traffic flow Abstracting Workloads Integrating Policies Controlling Traffic

Hyper-V Extensible Switch
Virtual Machine Virtual Machine Provides open platform supporting third-party plug-ins to add functionality Lets customers manage virtual network the same way they would manage a physical network Helps monitor the security of virtual machine to virtual machine traffic Provides unified management and enforcement of plug-ins with Virtual Machine Manager across entire datacenter Includes NDIS filter drivers, WFP callout drivers, Ingress filtering, Destination lookup and forwarding and Egress filtering extensions Extensions from Cisco, inMon, NEC, 5Nine Parent Partition VM NIC Host NIC VM NIC Virtual Switch Extension Miniport Extension Protocol Capture Extensions Extension A Filtering Extensions Extension C Extension D Forwarding Extension Physical NIC Hyper-V Extensible Switch architecture Integrating Policies Abstracting Workloads Controlling Traffic

Abstracting workloads with Hyper-V Network Virtualization
How network virtualization works Overlays multiple virtual networks on shared physical network Uses industry standard General Routing Encapsulation (NVGRE) protocol Blue virtual machine Yellow virtual machine Blue network Yellow network 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 VIRTUALIZATION Physical server Physical network Controlling Traffic Abstracting Workloads Integrating Policies 9

Hyper-V Network Virtualization
Tenants with overlapping IP Address range share same physical network Policies enforced at host level using PowerShell or System Center Virtual Machine Manager DHCP servers can be part of virtualized network to enable locally assigned IP addresses Supports guest clustering SQL Server Web Blue sees SQL Server Web Orange sees CUSTOMER ADDRESS SPACE What’s really happening n.n PROVIDER ADDRESS SPACE (PA) Hyper-V 1 Hyper-V 2 SQL Server SQL Server Web Web Controlling Traffic Abstracting Workloads Integrating Policies

Multi-tenant VPN Gateway
Challenges 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) Solution Multi-tenant VPN gateway in Windows Server 2012 R2 Integral multitenant edge gateway for seamless connectivity Guest clustering for high availability BGP for dynamic routes update Encaps/Decaps NVGRE packets Multitenant aware NAT for Internet access Bridge Between VM Networks & Physical Networks DNS SQL DC Contoso Fabrikam SPS VPN SPS VPN Internet Multi-tenant VPN Gateway Host Datacenter Network Virtualization Fabric Host Host Controlling Traffic Abstracting Workloads Integrating Policies

Controlling Datacenter traffic flow
What it means: Provides ability to control physical network hardware directly from applications Enforces routing policies on the fly Requires programmable hardware that uses a standard protocol like OpenFlow, Cisco OnePK and so on. Challenges: Adds complexity to the application Creates challenges in heterogeneous environment Use Cases? Applicable to certain classes of applications like Microsoft Lync, Network diagnostic tools, high fidelity video games Most Line of Business applications and workloads may not need this level of control Aggregation Switches ToR ToR VM VM Application Application Abstracting Workloads Controlling Traffic Integrating Policies
