DNS++: A Manifest Architecture for Enhanced Content-Based Traffic Engineering

As network utilization keeps increasing, it is essential to have mechanisms to better schedule traffic in the network. Using content-based resource allocation allows to deliver a fine- grained scheduling and to monitor not only the instantaneous link utilization but also the backlog that is already scheduled onto a link in the future. We propose to use a manifest prior to a session to inform the session manager of the requested bandwidth. We propose to make that information available to the scheduler in the data center context. We have implemented our scheme in a testbed and demonstrate a significant benefit for a data center use case.
