              Differential Computing Resource Reservation
               draft-liu-coin-differential-reservation-01

Abstract

   Computing in the network may require the embedded computing
   capability in the network device, such as gateway, switch, etc, and
   there might be so much distributed computing task in the network.
   Some new applications like AR/VR, motion control put forward higher
   demand of network than before, and AI is also considered to be used
   in the app and network.  In order to satisfy the demands, it needs to
   guarantee both the bandwidth resource and the computing resource
   which is linked by the network.

1.  Overview

   From cloud computing to edge computing, computing power is
   distributed and extends to customers.  In the future network and
   computing integration system, computing power will be distributed in
   all nodes as ubiquitous endogenous resources.  The user's request can
   be satisfied by calling the nearest node resource, which is no longer
   limited to a specific node.

   The basic topology abstraction of traditional Internet architecture
   is the end-to-end model: the network is in the middle, the computing
   is in the periphery, and the host realizes the logical virtual full
   connection through the network.  In the trend of network and
   computing convergence, computing resource may be embedded in the
   network.  From the perspective of completing users' computing tasks,
   embedded resources are no longer peer-to-peer relationship, but need
   to consider the different distances and network conditions.
