HPE OpenSDN Portfolio Overview As CSPs pursue their journey to becoming Digital Service Providers, they will need to address one of the most visible challenge in their current network infrastructure: The need for network programmability. That is, the ability to change network behavior on demand and in real time based on business logic or customer demand, and the resulting flexibility and service agility. Network programmability forms the foundation of their ability to adapt to changing customer demands and drive increased revenue by developing and quickly delivering new, innovative, and personalized services. Software defined networking (SDN) fulfills that need by transforming networks into programmable elements ("SDN Switches") implementing forwarding logic that is set dynamically according to business policy, customer demand, and system status. Implementing SDN in a carrier network is much different than implementing programmability in fairly homogenous networks (like data centers or campus environments) where SDN first originated. SDN implementation in CSP networks need to consider the huge diversity of network elements, vendors and protocols - in addition to the wide, geographically distributed deployments and stringent SLA requirements that are often regulatory mandates. The SDN solution in a CSP network needs to seamlessly integrate with existing management and orchestration solutions. Where CSPs have embarked on an NFV journey, the SDN solution must integrate and add value as a component of the NFV Infrastructure. And most importantly, a CSP SDN solution needs to be an open solution that addresses one of the most common pain point that CSPs talk about - vendor lock in. HPE's approach to SDN for CSPs is what we call OpenSDN. We see OpenSDN as an integral part of the Telco Cloud architecture which aims to transform the CSP infrastructure to be more programmable, operations to be more automated, and enables the services provided to be more personalized and on-demand. SDN and NFV play a vital role in that infrastructure transformation. HPE OpenSDN solutions are designed to complement our industry leading NFV solutions, to ensure network agility is at par with compute/storage agility. Our solutions ensure automated, policy driven, real time network programmability to support distributed VNF deployments, VNF mobility, and are redefining user experience by enabling personalization of services at massive scales. The HPE OpenSDN portfolio consist of an OpenDaylight-based carrier-grade SDN Controller. We add value to the base controller with a rich set of application packs that form the basis of our pre-tested solutions for most commonly used use cases. These application packs include:
The HPE OpenSDN portfolio helps CSPs to:
HPE's OpenSDN portfolio is an integral part of our NFV offering which includes:
OpenSDN for Data Center Networking OpenSDN for Data Center Networking is an HPE OpenDaylight distribution. OpenSDN is OpenDaylight that is tested, debugged and certified by HPE. Furthermore, HPE adds:
The first releases of the HPE OpenSDN product, as well as the remainder of this document, is focused on implementing and enhancing OpenStack Networking using an OpenDaylight Neutron ML2 Driver for OpenStack, including HPE's Helion OpenStack and RedHat OpenStack. This is illustrated in Figure 1. |

OpenSDN includes significant forwarding plane acceleration enhancements over OpenStack Neutron and OVS. OpenSDN utilizes OVS-DPDK which increases the forwarding performance of the Open Virtual Switch by a factor of 10 or more, from around 1-2Gbps per 2 cores to nearly 20Gbps per 2 cores. Furthermore, while traditional Neutron L3 routing requires packets to be sent to a Linux Router, traversing the vSwitch at least twice in the process, OpenSDN implements L3 routing directly on the vSwitch using OpenFlow rules, greatly increasing scalability and performance. Similarly, connectivity to external networks which requires NAT is also greatly accelerated.

Beyond implementing all required OpenDaylight functions and services as well as northbound and southbound interfaces, HPE OpenSDN adds carrier grade scalability and high availability including clustering of controllers at a single site and federation between controllers at multiple sites as well as the ability of connecting OpenStack instances using the federated controllers. Federation is achieved using a high performance, massively scalable, distributed database, and thus can be implemented over any IP network without the need to implement BGP.

In the data plane, HPE's controller enables inter-site host to host connectivity using VxLAN tunnels between hosts. In addition, HPE's Controller adds connectivity to legacy equipment, hosts running bare-metal, SR-IOV or PCI-PT and WAN gateways by implementing VxLAN to VLAN translation using the VTEP capable OpenFlow switches acting as gateways.
