Already, G is the norm in the network core; and DoCoMo Pacific is now beginning to build X G networks, with the help of Ciena. Verizon explained that it is doing likewise, and has added Cisco into its partner mix. Granted, DoCoMo’s service will not be delivered on a single G pipe, but through a mix of G and G facilities. Still, any data collection system in this pathway will look at an equivalent G pipe filled with traffic. Engineering plans for delivering G speeds are not far behind.
Collecting and managing such large data volumes is challenging in traditional physical network environments. The challenge comes not only from growing volumes, but also from the inherent transmission errors and dropped packets that come with higher speeds. Adding Network Functions Virtualization (NFV), Internet of Things (IoT)-based services, time-sensitive smart cars and smart cities, only escalates the challenge. Packet delay is intolerable for these services, all of which require near real-time communication. Network probe providers do a commendable job keeping pace with evolving networks by developing the capacity to collect most everything thrown their way; but even network probe vendors need help at times, from accelerators, load balancers, and storage solutions.
In response to virtualization, the need arose for the ability to dynamically collect data when and where it is most needed. Also, the need for a lower-cost and a more flexible alternative to hardwarebased network probes drove the industry to a software-based probe model. However, as flexible as software can be, its inability to process the variety and volume of data packet types in real-time makes even more processing and data delivery help necessary. In addition, because so many departments within the CSP business require access to network data, and view the importance of certain data sets as more germane to their goals, processing and delivering customized data sets is growing more complex.
The Operations, Orchestration, Data Analytics and Monetization (ODAM) applications that depend on timely, relevant data to support the CSP business are critical if CSPs are to evolve into the service innovators they must become. ODAM applications also provide the flexibility and real-time operational response that CSPs need to bring new services to market, on demand when required, or in hours or days for more complex services. One company featured in this report, Copenhagen, Denmark-based Napatech, is providing both the acceleration and data delivery capabilities that help ODAM and probe suppliers support CSPs in a manner demanded by today’s communications marketplace.
