Abstract

   This document introduce the Edge Datacentet network, and describe
   some use cases about Edge Datacenter, discuss an important component
   in the Edge Datacenter:Service Gateway and its functions.

   Service Gateway as a flow distribution device in the Edge DC network,
   it needs to not only play a gateway of the edge Datacenter network,
   implementing coordination with existing technology,but also meets
   many new requirements.  For example, acts as a traffic distributor to
   make sure the packets goes into Edge DC or Metro network, SDN
   forwarding, and as a leaf in the leaf-spin architecture.

1.  Introduction

   With the challenge and the chances of the new network SDN/NFV and the
   development of the Datacenter, the provider is facing many changes
   from traditional network, which is representive by traditional CO.
   How to use the resource of the traditinal CO fully and achieve the
   transition to the SDN/NFV is the problem providers and vendors need
   to consider.  CO re-architection is the attractive to more and more
   providers and vendors.  and getting more and more attention.  Using
   lots of CO resource, the providers can re-architected CO to Edge DC,
   which is more adaptive in SDN/NFV.

   In this document, we will present the description of the Edge
   Datacenter and its main component Service gateway.  As a result, some
