Huawei Demos SDN Virtual Transport Service

Huawei demonstrated a transport SDN prototype capable of delivering Network on Demand (NoD) services.


Huawei's SDN virtual transport service solution is based on its Path Computation Element (PCE) architecture.

The goal of the virtual transport service platform is to provide users with multiple modeled virtual topologies through programmable interfaces to meet on-demand virtual network service (such as NoD service) user requirements in real time.

Huawei said its platform can help carriers deliver customized services and deploy value-added services efficiently and flexibly. An intelligent Transport Path Engine (TPE) algorithm ensures dynamic network resource optimization.

The announcement follows Huawei's demonstration of a transport SDN controller prototype launched last year.

SoftCOM is Huawei's end-to-end ICT network architecture based on concepts such as cloud computing, SDN, NFV, and network openness.

The demonstration occurred at the recent Layer123 conference in Bad Homburg, Germany.  In a keynote address at the conference, Justin Dustzadeh, Huawei's CTO & VP Technology Strategy, said Carrier SDN ultimately will be an end-to-end framework spanning Last Mile, Access, Aggregation, Metro & Core, and Data Center equipment. He presented several SDN use cases, including:


  • SDN-based Mobile Backhaul
  • Virtualized Residential Gateways with virtual set-top boxes
  • Traffic Steering for Gi-LANs
  • Cloud IMS
  • SDN-based Transport Network Virtualization


Huawei is also continuing work on its Protocol-Oblivious Forwarding (POF) technology, which is a software-defined networking (SDN) forwarding implementation.  The goal is to leverage the OpenFlow protocol in a programming model where forwarding devices are no longer limited by pre-defined packet protocols or forwarding rules.  Data plane hardware would not be limited by hard­-wired protocol implementations. POF has been prototyped on Huawei's NE5000E Core Router
