Network Development and Deployment Initiative (NDDI) Open Exchange Software Suite (OESS) is an application to configure and control OpenFlow enabled switches through a very simple and user-friendly user interface. OESS provides subsecond circuit provisioning, automatic failover, per-interface permissions, and automatic per-VLAN statistics. Though it supports multiple features, it is yet to support MAC address learning, VLAN dot1q tunneling (Q in Q), and Quality of Service (QoS).

It is supported by these switches: Brocade MLXe, Cisco ASR9000, Dell S4810, IBM G8264, Juniper MX960, and NEC PF5820.
