As SDN is rolled out further across the network more efficiencies are realised.
With ROME, SDN coverage can be extended to the physical interconnectivity between network locations
The Benefits Of SDN
Typically SDN deployments and the efficiencies that it delivers have been focussed on Layer 2 through to Layer 7 of the network.
The use of NFV (Network Function Virtualisation) technology has meant that virtualised network appliances and application servers can now be deployed as software images on pre-installed generic servers, replacing dedicated hardware devices.
Network hardware devices such as Ethernet switches and firewalls have been replaced by software images that can be deployed to deliver the same network function as the original hardware devices.
As well as the reduced time to deploy these devices delivered by using NFV, SDN allows the realisation of further efficiencies by automating the deployment of these functions. SDN control software works across the network and can automatically reply and configure NFV functions. Interfaces into the provisioning system for the controlling entity - whether that be a Telco or Data Centre operator - mean that network configuration can be automated to meet customer need incredibly quickly.
The Transport Layers
Generally the interconnection layers between network locations have been thought to be "fixed" . These may consist of high-speed Ethernet links (100G, 400G or faster) that still require dedicated hardware, as well as OTN (Optical Transport Network) and the underlying physical fibre infrastructure.
However, vendors of the network devices at this layer have also started to support SDN functions at these lower layer, allowing traffic grooming at the wavelength layer using ROADM devices or at the ODU container level within OTN devices.
Still below these layers lies the physical infrastructure, and regardless of whether you are deploying virtualised network devices or hardware with SDN control support, this still relies on physical human activity to make appropriate cross connections and fibre cord patching.
ROME - Robotic Optical Management Engine
ROME is a robotic optical switch that offers dynamic fibre cross connect functions, removing the the automation gap present capability at the physical network layer.
ROME enables physical fibre connections to be made automatically, remotely, quickly, and without on-site manual intervention. ROME delivers superior optical performance and low insertion loss.
With ROME, data center, telco & lab operators benefit from reduced CAPEX and OPEX as well as improved reliability and security, while future-proofing their critical infrastructure.
Extending SDN To Physical Connectivity
With a ready-to-use API, the ROME can be easily integrated into an existing SDN environment.
SDN has already transformed todays networks, enabling new services and applications to be deployed and scaled faster than ever. All these services, from Ethernet switching to the application layer, all rely on the physical layer for connectivity. Being able to now automate this final layer of the network can bring huge OPEX savings and revenue gains to service providers.
For specialised services such as DWDM channel services or high speed services such as 100G / 400G Ethernet where dedicated hardware is still a requirement, automating the interconnection of these across the network and to the customer brings them closer to scalable,automated deployment.
