Expo Theater II
Session organized by IEEE Big Data Initiative
New streaming telemetry methodologies, and related network analytics, have been increasingly discussed as an important “SDN” innovation in next‐generation wide‐area (WAN) transport. More specifically, leading network operators have proposed innovative WAN automation and abstraction “SDN” frameworks (OpenConfig, Open‐ROADM) which identify telemetry as a very important use‐case. More specifically, OpenConfig identifies telemetry as its top priority, and 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” streaming telemetry implementations from all the major routing vendors! This trend has now (last 12 months) been extended to optical transport, with initial focus on the DCI WDM.
The underlying motivation for this evolution in network operations is to a great extent 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 Weboperators’ 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 of senior members of network operations and engineering from service providers (traditional telecom, cable, and cloud/content) will discuss 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 cloudbased 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” streaming telemetry implementations in routers be also in optical transport systems?

Loukas (Lucas) Paraschis is senior director of data‐center transport for Internet cloud and content providers at Infinera. From 2007‐2015 Loukas was cisco’s senior technology architect for WAN transport in global service provider, and before a cisco technical leader in optical networking and routing (2006‐2000). He completed graduate studies at Stanford University (PhD applied physics 1999, MS EE 1998), has (co)authored more than 100 peer‐reviewed publications, invited, and tutorial presentations, a book, two book chapter, and three patents, and has been associate editor for the Journal of Optical Communication and Networks, guest editor of the Journal of Lightwave Technology, chair of multiple conference organizing committees, Fellow of the OSA (2011), senior member of the IEEE (2006), and was an IEEE Photonics Society Distinguished Lecturer (2009). Loukas was born in Athens, Greece, where he completed his undergraduate studies.
