Connections 2022 - Hot in Networking Track

India Internet Engineering Society (IIESoc) & Industry Network Technology Council (INTC) will be organizing the 5th iteration of Connections as a joint India-US fully online event on April 2-8 2022.

Register - HERE

The timing of the event would be 19:30 India, 14:00 UTC, 10:00 ET, 07:00 PT for 2.5 hours each day.

Day 3 (Wednesday) would be the Hot in Networking track -

Lightweight Mixnets by Martin Thomson

Networked services are an integral part of how a connected world operates. We use them every day, often without realizing it. But our use of services can create a lot of waste information, a lot of which is private. This private information often accumulates in servers. While some services find uses for that information, those uses can be disrespectful of individual privacy. Oblivious HTTP is a new lightweight protocol that can be used to minimize the amount of private information that servers are exposed to.

Martin Thomson enjoys making protocols. He takes particular pride in making protocols that lots of people use, like HTTP/2, QUIC, and WebPush. Making protocols that are safer - more secure and private - is his particular focus. Martin is a Distinguished Engineer at Mozilla.

Semantic Routing - Challenges and Benefits of Routing on More than Just Addresses by Adrian Farrel

Routing of IP packets is well-known to be based on distributed algorithms that select the next hop towards the destination address along the best path to the destination. The measure of “best” is based on the metrics associated with the link. Typically the algorithms that calculate the best path are known as “shortest path first.”

Traffic Engineering (TE) techniques were developed to provide more sophisticated control of the paths that collections of packet flows took through the network to guarantee bandwidth and steer traffic away from the shortest paths.

Upper-layer applications (such as multiplayer immersive gaming, remote surgery, holographic conferencing, or even haptic augmented reality multiplayer 3D worlds) are now placing increasingly sophisticated demands on the network for better quality, more predictability, and increased reliability. At the same time, lower-layer network technologies are advancing rapidly, providing increased bandwidth to the home and to mobile hand-held devices creating an environment that enables the potential of advanced applications running concurrently by vast numbers of end-users. These demands coincide with a growing trend to extend end-to-end communications to include machines and services through 5G, IoT and vehicular connectivity, and space-terrestrial communication.

The convergence of these innovations places requirements on the network to deliver particular service level behaviors on a per-flow basis. Unfortunately, TE techniques for bundling extensive collections of flows are neither scalable nor sufficiently granular to meet these needs.

Semantic Routing is the process of achieving enhanced routing decisions based on semantics added to IP headers to provide differentiated paths for different packet flows distinct from simple shortest path first routing. The additional information or "semantics" may be placed in existing header fields (such as the IPv6 Traffic Class field or the destination address) or may be achieved by adding fields to the header.

This talk will examine the application of Semantic Routing and how it allows packets from different flows (even between the same applications on the same devices) to be marked for different treatment in the network.

We will present an overview of some of the many ways that Semantic Routing has been proposed, from some well-established techniques to newer proposals such as SRv6 Network Programming and Application-Aware Networking (APN). We will also examine how Semantic Routing may be integrated with SDN and programmable forwarding planes.

After a short discussion of the challenges and risks to the routing system associated with Semantic Routing, we will conclude with a description of the research challenges of Semantic Routing and an overview of where the research is being discussed.

Adrian Farrel has been at the forefront of technology innovation in the Internet Engineering Task Force (IETF) for nearly 25 years and has co-authored more than 85 RFCs specifying Internet technology. He was part of the effort that developed Multiprotocol Label Switching (MPLS), and was one of the pioneers of Generalized MPLS (GMPLS) and the Path Computation Element (PCE). Within the IETF, Adrian has co-chaired a number of working groups (CCAMP, PCE, L1VPN, L2SM, L3SM, and I2NSF), and served as one of two IETF Routing Area Directors for six years. He is currently the Technical Advisor to the IETF’s TEAS working group and has just reached the end of a four-year term as the Independent Submissions RFC Editor. Adrian has written, edited, or contributed to nine books on Internet technologies including “The Internet and Its Protocols” and “GMPLS - Architecture, and Applications”, and has also authored four volumes of fairy stories for adults of all ages. He runs a successful consulting company, Old Dog Consulting, specializing in Internet protocols, SDN, and NFV.

Computation in the Network (COIN) by Dirk Trossen

Computation in the Network (COIN) is a wide-ranging term as well as the name of an RG effort in the IRTF. This presentation aims at providing some insights into what COIN maybe, where it may be headed, and what work it may entail. Those insights are based on individual participation in the COIN RG with some example activities to underlie the key points. The presentation will also utilize the ongoing use case draft efforts to relate to some aspects of COIN.

Dr. Dirk Trossen (male) is a Chief Network Architecture Researcher at Huawei’s Applied Network Technology Laboratory. His main responsibility lies in researching new network technologies for the Next Generation Internet through research engagements, including direct university relations. Dirk has more than 25 years of experience in network architectures, services, and wireless technology with main contributions in the area of inter-domain networking as well as seamless handovers, physical network overlays, and new service concepts for operators. He was the technical lead of the FP7 efforts PSIRP and PURSUIT, performing research on large-scale publish-subscribe information-centric systems. Prior to joining Huawei, Dirk was a Senior Principal Engineer at InterDigital Europe, Ltd, leading the network research team in the London office as the technical lead of the H2020 POINT, RIFE, and FLAME projects on service-based architectures. Until April 2013, Dirk was a Senior Researcher at the Computer Laboratory of Cambridge University. Prior to this, Dirk was Chief Researcher at BT Research from 2007 to 2009 and Senior Principal Scientist with Nokia Research from 2000 to 2007. From 2009 to 2019, Dirk was also a Research Affiliate with the Advanced Network Architecture group at MIT CSAIL. He holds a Ph.D. degree in Computer Science from the Technical University of Aachen, Germany, and a diploma degree in Mathematics from the same university. He published more than 85 peer-reviewed papers in international conferences and journals and holds currently more than 30 international patents in various areas. He was listed among the top 50 Industrial IoT Innovators in the 2016 RCR Wireless list.
