Communication service providers (CSPs) are seeking out new tools and technology to increase agility. To that end, they are looking at two network virtualization capabilities—software defined networking (SDN) and network functions virtualization (NFV)—to help them along in their journey. NFV, which replaces integrated physical network appliances with software-based virtualized functions deployed on standardized server platforms, enables CSPs to quickly develop and deliver innovative, personalized services for their customers. SDN complements NFV by providing a framework for network programmability.
A new white paper from Hewlett Packard Enterprise (HPE) discusses how the marriage of SDN and NFV has, so far, been difficult to achieve in CSP networks. Most SDN approaches were originally designed for homogeneous data centers, not large-scale telco networks hosting a diverse set of network functions and services, with thousands of physical and virtual devices from multiple vendors. And although the industry and the open-source community have made huge strides in NFV with the OpenStack platform, OpenStack itself does not include SDN programmability.
HPE is putting new SDN technologies to the test and benchmarking the performance improvements they deliver. Although OpenStack alone can’t meet many of the requirements for carrier-grade services—especially around networking performance—SDN innovations from HPE and the open-source community are making carrier-grade OpenStack a reality. Two key initiatives are making it possible: a performance-optimized version of Open vSwitch (OVS) that uses Data Plane Development Kit acceleration (OVS DPDK), and the OpenDaylight (ODL) open source SDN controller.
Read the white paper to see how HPE sees carrier-grade SDN as an integral part of the telco cloud architecture, which aims to transform CSP infrastructures to be more programmable, operations to be more automated, and CSP services to be more personalized and on demand. HPE’s OpenSDN portfolio is designed to complement its industry-leading NFV solutions to enable network agility on par with compute and storage agility. HPE’s solutions enable automated, policy-driven, real-time network programmability to support distributed VNF deployments and enable VNF mobility. And they are redefining the user experience by enabling personalization of services at massive scale.
