SDN: Focus Areas

•  Current considerations •  Ethernet fabrics, cloud-scale routing, and application delivery •  Support for OpenFlow and OpenStack

•  OpenFlow for 3 key applications: •  Network virtualization •  Flow Management (Traffic engineering) on the WAN •  Flow Management on Carrier Ethernet Networks

•  Standardization efforts •  Open Networking Foundation (OpenFlow standardization) •  OpenStack.org (OpenStack standardization)

§  A SDN application that enables the creation of logical networks (multi-tenancy) over a common physical network

§  Logical networks contain VMs and physical workloads (e.g., physical servers, firewalls, etc)

§  Enables seamless control of network resources regardless of location

§  Logical networks can be used to bridge private and public clouds

Flow Management in the Metro/WAN A SDN Application using OpenFlow

•  OpenFlow is well suited for flow management in the metro/WAN

•  Facilitates deployment of innovative new applications, e.g.,

•  Global network optimizations •  Solving complex traffic engineering

challenges •  Support traffic engineering incorporating

business rules

•  Applicable to Layer 2, Layer 3, and MPLS networks

Service Provider OpenFlow Controller used to setup a traffic tunnel between customer sites A and B OpenFlow Controller pushes the

tunnel configuration to the required LERs and LSRs

Service is enabled and traffic flows between customer sites

Congestion sets in on network node. Customer flow needs to use an alternate path.

OpenFlow Controller is used to set up alternate path and to tear down old path.

•  Engineer long lived flows in metro and core networks •  Layer 2, such as PB (802.1ad) and PBB (802.1ah) networks •  Layer 3 (routing) •  MPLS

•  SP customers with metro/core Layer 2 networks •  Applications can use the capability of OpenFlow matching rules applicable to

Layer 2 fields, e.g., source MAC address, destination MAC address, VLAN ID

Other Use Cases in Carrier Ethernet Networks For Layer 2 networks

© 2011-2012 Brocade Communications Systems, Inc.

•  SP customers with metro/core Layer 3 networks •  Applications can use the capability of OpenFlow matching rules applicable to Layer 3

fields, e.g., source IP and destination IP addresses •  Tackle growing size of Internet routing table

•  SP customers with metro/core MPLS networks •  Applications can use the capability of OpenFlow matching rules applicable to MPLS

labels and OpenFlow actions to add and remove MPLS labels

•  Requires OpenFlow v1.1 capabilities

•  Hyper-scale Data Centers •  Address the Virtual Machine (VM) scale challenge with OpenFlow and facilitating

VM mobility •  Facilitating multi-tenancy

•  Network Virtualization •  Simplifying multi-tenancy (also part of our hyper-scale DC solution)

•  Flow Management in metro/WAN •  Traffic engineering, load balancing, security management, and etc

•  Enterprise/campus data center applications •  Reduce operational complexity and facilitating deployment of new features
