SDN/SD-WAN Services




Customer-oriented Application, Services, and Service Platforms rollout with SDN technology. Providing single pane of glass for the end to end network orchestration and reduces time to market for new services. 


Remote work force and home office collaborations has brought a enormous surge of voice, video and data traffic and thereby increase in low latency bandwidth needs. This has further accelerated the need to transform traditional WAN into software-defined policy-based, application-aware virtualized routing solutions.


This has enabled seamless movement of data and applications across a hybrid-cloud environment. This also offers a single pane of glass for the end to end network orchestration and reduces time to market for new services

Opportunities & Challenges

SD-WAN as a technology based on Gartner report 2019 is at the Slope of Enlightenment and it will reach its peak over the next 2 to 5 years. 

SD-WAN which is inherently software centric, brings in complexity in modelling and deploying the services. 


While implementing SDWAN the following challenges must be considered 

1. Backward Compatibility – Interoperability with legacy devices must be addressed.

2. Architecture consideration - Service providers can opt for the deployment of SD-WAN orchestrator along with SD-WAN controller either centralized or based on a hierarchical model depending on the scale of the services.

3. Design – Integration layer needs to be designed to unite the Legacy IT systems with SD-WAN solution

4. Updation –  Decisions on already deployed SD-WAN solutions, may need to evolve and adapt to the modern SD-WAN trends like SASE.  

5. Maintenance – As the technology is getting evolved, post-deployment of SD-WAN solution and services requires a Next Gen Managed Services
