Abstract:
This document describes Hierarchical SDN (HSDN), an architectural
solution to scale the Data Center (DC) and Data Center Interconnect
(DCI) networks to support tens of millions of physical underlay
endpoints, while efficiently handling both ECMP and any-to-any end-
to-end Traffic Engineered (TE) traffic. HSDN achieves massive scale
using surprisingly small forwarding tables in the network nodes and
brings key simplifications in the control plane as well. The HSDN
forwarding architecture is based on four main concepts: 1. Dividing
the DC and DCI in a hierarchically-partitioned structure; 2.
Assigning groups of Underlay Border Nodes in charge of forwarding
within each partition; 3. Constructing HSDN MPLS label stacks to
identify the endpoints according to the HSDN structure; and 4.
Forwarding using the HSDN MPLS labels.
