Google:Inter-datacenter WAN using OpenFlow

Below are sample SDN use cases we’ve heard from potential users.

Use-cases in production
New Use Case Intra-Datacenter Interconnect* Questions about this use case? SDNCentral can help you find an expert	Is a use case where you can use OpenFlow to provide dynamic traffic steering between datacenters over the WAN via centralized traffic engineering with an OpenFlow Conroller. What OpenFlow can do: Perform advanced traffic engineering with low cost hardware, with the people and processes you have today, and design network on deterministic behavior instead of overprovisioning Mirror production traffic for testing (or other purposes) Create test environment before you turn ‘on’ in production Upgrade capabilities without downtime What you need to implement: OpenFlow Controller OpenFlow enabled switch (or your favorite Optical transport gear that can speak OpenFlow) This is a very cool use case – read more about how Google implemented OpenFlow. This use case is also popular with financials who need advanced traffic engineering for things like disaster recovery, big data, and moving virtual machines (and the data required for them to be useful).
New Use Case Virtual Patch Panel* Interested in this use case? SDNCentral can help you find an expert	Is a use case where you can use OpenFlow to create a virtual patch panelacross multiple physical switches. One primary use of the virtual patch panel is to enable network monitoring without needing to purchase a special monitoring switch (say Gigamon or VSS Monitoring). What OpenFlow can do: OpenFlow Controller Connect two ports on a switch you want to interconnect and insert two static flows that directs any incoming traffic on one port to the other port. What you need to implement: OpenFlow enabled switch that allows you to insert static flows into the TCAM (No Controller) This is a very simple use case, that can solve an important, but not mission critical use case.
Generic use cases
Hyperscale Public Clouds	Hyperscale Public Clouds use case are for the leading public cloud vendors (Amazon, Google, Facebook, MSN, Yahoo, Badu, Racksapce, etc) who adopt SDNs to meet demand due to hyperscale growth in the use of their data center assets. These customer have very large domain isolation, service and server mobility, data center utilization and scalability, and unique dynamic provisions requirements They use case if usually defined by a) customer need to increase data center utilization; and b) a customer who’s need is so compelling they will build their own SDN solutions rather than buy
Hyperscale Web 2.0	Hyperscale Web 2.0 use case is same as the Hyperscale Public Cloud use case except it’s targeted at large scale Web 2.0 companies such as SaaS, PaaS, and smaller IaaS providers. They provider have the same economic incentive to adopt SDN as HyperScale Public Cloud Providers; however due to the relative scale size these customer are typically more willing to purchase a solution from a vendor.
Enterprise Private Cloud	Enterprise Private Cloud use case is where the largest of enterprise, universities, and governments deploy their own Amazon Web Services (AWS) like services behind their firewall due to security concerns or compliance requirements. These are smaller scale use cases from the Hyperscale usecases, but very similar requirements
Enterprise Security	Enterprise Security use case is where SDN is used to deliver high throughput, low latency security for domain isolation intra data center (i.e. within a single data center).
Enterprise Access Layer	Enterprise Access Layer use case is where SDN is used to optimize the Enterprise Campus Network which traditionally includes Campus switching and WLANs. While not OpenFlow, one could assert that the original enterprise SDN deployment was the Controller based Wireless LAN pioneers by AirSpace (Cisco) and Aruba.
Enterprise WAN	Enterprise WAN use case is where SDN is used for inter data center connections to facilitate high bandwidth, low latency storage replication, disaster recovery, or virtual machine (and data migration) to increase per data center utilization or deliver some level of resiliency between multiple enterprise data centers.
Service Provider Mobile Access Layer	Service Provider Mobile Access Layer use case is where Mobile Service Provider plan to implement SDN technologies to meet demand due to hyperscale growth of mobile devices including SmartPhones and Tablets. The use case includes using SDNs to unify 3G / 4G with Offload WIFI networks and integration with technologies such as HotSpot 2.0
Service Provider Wired WAN	Service Provider Wired WAN use case is where Service Provides – specifically Telco’s, Carriers, and MSOs – plan to implement SDN technologies to cost – optimize their WAN infrastructure (specifically Metro Ethernet, Optical, and other long haul technologies).
