Challenges faced in building our own solution • Topology and deployment • Introducing our network to production • Unmanageably high number of cables/fiber • Cluster-external burst b/w demand • Control and management • Operating at huge scale • Routing scalability / routing with massive multipath • Interop with external vendor gear • Performance and reliability • Small on-chip buffers Tune switches (eg ECN) and Hosts (DCTCP) • High availability from cheap/less reliable components 26
