                      draft-kutscher-coinrg-dir-01

Abstract

   In-network computing can be conceived in many different ways - from
   active networking, data plane programmability, running virtualized
   functions, service chaining, to distributed computing.

   This memo proposes a particular direction for Computing in the
   Networking (COIN) research and lists suggested research challenges.

1.  Introduction

   Recent advances in platform virtualization, link layer technologies
   and data plane programmability have led to a growing set of use cases
   where computation near users or data consuming applications is needed
   - for example for addressing minimal latency requirements for
   compute-intensive interactive applications (networked Augmented
   Reality, AR), for addressing privacy sensitivity (avoiding raw data
   copies outside a perimeter by processing data locally), and for
   speeding up distributed computation by putting computation at
   convenient places in a network topology.

   In-network computing has mainly been perceived in five variants so
   far: 1) Active Networking [ACTIVE], adapting the per-hop-behavior of
   network elements with respect to packets in flows, 2) Edge Computing
   as an extension of virtual-machine (VM) based platform-as-a-service,
