Analytics are expected to play a major role in developing the intelligence to control virtualized networks and more efficiently make use of network resources. What progress has been made deploying real-time analytics and integrating that intelligence into virtualized networks to deliver more fully on the promise of NFV?
At Big Communications Event last month, Michael Rezek, Accedian VP of Business Development and Strategic Partnerships, was on a panel exploring those and related questions. Some of his points are summarized below; the full panel video is also now available for a deep look at integrating analytics with virtualized networks.
- Making it possible to timestamp collected packets as near the bare metal (server) as possible.
- Using adaptive learning techniques to better coordinate timestamping.
- Expose the data in some kind of open exchange format so it can be easily consumed
- Perform all meaningful correlations possible within the dataset (such as correlating QoS/network performance and QoE/application performance
In a nutshell, while virtualization potentially introduces new efficiencies and revenue streams, it also introduces new types of complexities that require automation, which relies on instrumentation for effective visibility.
Essentially, Rezek said, here’s what virtualized networking means:
- Disaggregating many physical elements
- Extracting layers of software from physical elements
- Reassembling those layers as software on x86
- Adding hypervisors, virtual infrastructure managers, and orchestration
Because of this complexity, Rezek noted, “the ability to instrument and have the visibility and the telemetry is going to become more important than ever because every layer of software and the x86 all have different release cycles and different versioning, with more frequent updates than in the physical world.”
Rezek also brought up the concept of a closed-loop control system, where ubiquitous network visibility feeds intelligence into the control plane, which converts policy and analytics into network configuration actions. This moves things into the realm of true network automation.
“I’m amazed at how little focus there is on the security aspect of NFV,” Rezek said. “Everybody thinks in terms of perimeter protection but most of the threats that occur are within the network.”
