Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today's applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.

Many organizations are working to develop industry standards for SDN including the Open Networking Foundation which is a user-driven organization dedicated to the promotion and adoption of SDN standards like OpenFlow®.

Mentioned below are some of the strategic benefits of SDN architecture in Wireless Networks

  • Agile and Flexible: Abstracting control from forwarding lets admins dynamically adjust network-wide traffic flow to meet fluctuating demands
  • Central Managed: Network intelligence is centralized in software-based SDN controllers
  • Programmatically configured: SDN lets network managers configure, manage, secure, and optimize network resources very quickly via dynamic, automated SDN programs
  • Open standards and vendor-neutral: SDN simplifies network design and operation and has multi-vendor support

 

HSC’s expertise in the SDN space:

HSC has a dedicated team of Wireless and Infrastructure team who dedicatedly work for advancing the SDN technology. Our Wireless team has been working on Transition from fixed backhaul links to high-capacity inter-node mesh networks by working on mmWave based software defined network (backhaul) . Some more highlights about this solution are as follows:

  • Cost-effective, high-capacity and low-latency solution for small-cell backhaul based on the IEEE 802.11ad standard
  • Multi-Sector Millimeter Wave Mesh nodes with phased array antennas
  • Network formation by automated neighbor discovery and association
  • Use of dynamic beam-forming
  • Software defined mesh network topology for optimal connectivity and power savings
  • High speed packet switching using DPDK

SDN helps in dynamic provisioning of network elements and services to inside a data centre instead of the current manual provisioning of network and security resources. It also helps in better network management and thus reduced operational costs.

HSC is currently working on several projects with various customers to help them incorporate programmability and agility into their network, and therefore enabling them to keep pace with modern business demands. Over the past few years, HSC has worked with wireless OEMs to develop SDN applications on Centralized Network Controller which controls the topology / scheduling / routing decisions in a backhaul network.If you have a specific query with regards to the application of SDN in Wireless Networks, please use the form the form below to send in your queries.
