Expo Theater II
Session organized by IEEE Big Data Initiative
New streaming telemetry methodologies, and related network data-analytics, has been increasingly discussed as an important “SDN” innovation in next-generation wide-area (WAN) transport. More specifically, leading network operators have proposed innovate industry “SDN” frameworks, most notably Openconfing, and more recently Open ROADM, which identify telemetry as the first important use-case of WAN automation and abstraction. Opeconfig explicitly aims to remove the limitations of the current network monitoring technologies (notably SNMP), by replacing traditional data-pull implementations with data-streaming monitoring, starting a couple of years ago from routing analytics. It has already enjoyed significant evidence of success in “all you can eat” telemetry implementations from all the major routing vendors! This trend has now (last 6-9 months) been extend to optical transport, with initial focus on the WDM DCI.
The underlying motivation for this network operations evolution is to a great extend related to the pervasive “scale-out” of “SDN” related automation, abstraction, and data-analytics innovations employed initially inside the data-centers (DCs). In this sense, the automation “gold standards” set by hyper-scale compute inside the Web-operators’ massively scalable DCs are now being extended to WANs, with the exciting end-goal of a fully autonomic, policy-driven network operation paradigm with very little (if any) human intervention. However, extending the automation achievements of compute to networking, let alone WAN, presents a few significant challenges; notably WANs are characterized by significantly more heterogeneity in technology (hardware and software), failure modes, and performance metrics (e.g. latency variation in the WAN can be 3 to 9 orders of magnitude bigger than in compute).
This panel will invite senior members of network operations and engineering from service providers (traditional telecom, cable, and cloud/content) to debate the most important characteristics, and value of network streaming telemetry and data-analytics in next generation WAN transport. Building on the two previous related OFC panels – on SDN Transport for Cloud Services (2015), and System Disaggregation in Transport (2016), it will also aim to identify the synergies among SDN, disaggregation, and big-data for transport of the next-generation of cloud-based service delivery. Among the many interesting topics, the panel will particularly aim to explore:
- What are the key technology and system innovations in this new generation of WAN telemetry (compared to previous telemetry ideas that started from the Bell Labs E2A architecture 30 years ago)? For example, GOOG reported at OFC 2016 on leveraging (SPRING) routing inside the DC for OAM&P, how useful would SPRING based telemetry may be for WAN packet, and even optical, transport?
- What are the key similarities and differences in network monitoring and data-analytics between routing and optical transport? For example, how appropriate would the initial “all you can eat” telemetry implementations in routers be also in optical transport systems?
Debating the role of network telemetry and big-data analytics in next generation transport networks, is a new, and very important practical topic for the whole OFC, IEEE and OSA communities. The topic also combines routing, optical, and multilayer transport, with SDN, network management and control-plane evolution, with “cloud", and compute.
