SDN Applications In the New IP Must Focus on Traffic Flows

Service providers continue to be challenged with the explosive network traffic growth based on mobility, cloud and video services as evidenced with their demands for large 100Gbps transport links and beyond. At the same time, service providers need to continue deploying new technologies and services to stay competitive and address the needs of their customers. In building their next-gen networks service providers aim to be efficient and cost effective while leveraging new technologies such as network virtualization, big data analytics and IP Voice (VoLTE & VoWIFI), which in turn come with their own challenges. And this all needs to be completed while addressing concerns around things like security, increased network visibility and more granular service flow management. These must be addressed as part of enabling new services successfully.

 

The New IP is focused on providing service providers all the necessary tools to efficiently deliver new services quickly in an automated and on-demand fashion. Using an open standards-based approach in hardware (e.g. Brocade MLXe router) working in concert with open SDN controllers (e.g. Brocade Vyatta Controller based on OpenDaylight), enables one of the industry’s first software defined networking (SDN) applications known as Volumetric Traffic Management (VTM).

 

This VTM application was developed to provide service providers with visibility into the different traffic flows across their networks and quickly manage them accordingly: whether it be to re-route a particular flow to better manage congestion or increase quality of service and prioritize traffic based on specific committed SLAs.

With the recent focus on security because of the growing number of breaches, it is imperative that service providers become more pro-active in terms of awareness of and taking action against infected traffic entering their respective networks. Distributed Denial of Service (DDoS) can create severe network performance degradation resulting in SLA violations, lost revenue, lost productivity and increased costs. Additionally, amplified NTP reflection attacks that broke the 100Gbps barrier in 2014 result in massive influx of infected traffic disrupting services. With Brocade’s VTM, service providers can now gain better insight into their network traffic, mitigate security breaches and design more efficient networks, while they add new services quickly and improve customer experience.
