eSDN: Rethinking Datacenter Transports Using End-Host SDN Controllers

摘要

We propose eSDN; a practical approach for deploying new datacenter transports without requiring any changes to the switches. eSDN uses light-weight SDN controllers at the end-hosts for querying network state. It obviates the need for statistics collection by a centralized controller especially on short timescales. We show that eSDN can scale well and allow a range of datacenter transports to be realized.
