Advanced Networking: Lightning Talks (Wednesday)

Time 09/28/16 04:10PM-05:00PM

Room Trianon

Session Abstract

In this session, four presenters provide short talks on topics of interest to generate further discussion – these Lightning Talks hope to encourage on-going discussion:

  1. Jeronimo Bezerra (Florida International University) on "Assessing the Quality of Flow Measurements from OpenFlow Devices" -- Since its initial proposal in 2008, OpenFlow has evolved to become today’s main enabler of Software-Defined Networking. OpenFlow specifies operations for network forwarding devices and a communication protocol between data and control planes. Although not primarily designed as a traffic measurement tool, many works have proposed to use measured data from OpenFlow to support, e.g., traffic engineering or security in OpenFlow-enabled networks. These works, however, generally do not question or address the quality of actual measured data obtained from OpenFlow devices. Therefore, in this presentation (derived from a paper presented at the Traffic Monitoring and Analysis workshop 2016) we assess the quality of measurements in real OpenFlow devices from multiple vendors. We demonstrate that inconsistencies and measurement artifacts can be found due to particularities of different OpenFlow implementations, making it impractical to deploy an OpenFlow measurement-based approach in a network consisting of devices from multiple vendors. In addition, we show that the accuracy of measured packet and byte counts and duration for flows vary among the tested devices, and in some cases counters are not even implemented for the sake of forwarding performance.

  2. Yatish Kumar (Corsa Technologies) on "Encapsulation-as-a-service: What is it, and why you're really going to want it" -- We often discuss network services in terms of forwarding behaviour. AL2S, AL3S, transit, peering etc. However encapsulation is not always thought of as a service, or even a specific layer in the OSI model. In this talk we discuss the possibilities that can be opened up in terms of network use cases when we think of encapsulation as a service provided by your ISP or upstream provider.

  3. Jason McConnell (Texas A&M University) on "Using IMS to Converge Wireless Service Providers Network with Campus Enterprise Networks" -- For the past several years the wireline and the wireless service providers have been embracing the IP Multimedia Subsystem (IMS) to offer seamless integration of services such as UC between networks. IMS offers support for QoS between networks supporting a reliable, repeatable user experience. This session will describe the IMS architecture, demonstrate the functional elements required to support IMS, and define a possible IMS NetPlus Internet2 service offering.

  4. Michael Sinatra (ESnet) on "The Science DMZ as a Security Architecture" -- In this lightning-talk version of a longer presentation given at the NSF Cyberinfrastructure Security Summit in August 2016, I look at the issue of "Science DMZ Security" in a novel way, arguing that the Science DMZ is itself a security tool in the arsenal of a risk-based campus security approach. In the full version of the talk, I compare risk-based and control-based security approaches, argue how the Science DMZ is a best fit for a risk-based approach, and include some detailed examples of how the Science DMZ actually improves the overall campus security posture. The lightning talk version will touch on some of these topics and provide references to the full paper.
