Evaluating the impact of SDN-induced frequent route changes on TCP flows
2017
2017 13th International Conference on Network and Service Management (CNSM)
Preserved Fulltext
This work analyses and evaluates the impact of frequent route changes on the performance of TCP flows. ...
It is argued, however, that changing the paths of TCP flows too often could severely impact their performance by incurring packet loss and reordering. ...
This work is also supported by the CHIST-ERA STAR [23] project. We also thank Daniel VALENTIN for implementing the ONOS application used for traffic rerouting. ...

Middleboxes complicate the management, the deployment, and the operations of the entire network. ...
Moreover, they induce network performance issues and scalability limitations by requiring huge amounts of traffic to be, often sub-optimally redirected, and sometimes redundantly processed. ...
However, with EnforSDN, the configuration changes as soon as the Firewall approves the flow, based on the first packet (resolution phase). ...

On a 10 Gbps commodity switch, Planck-driven traffic engineering achieves aggregate throughput within 1-4% of optimal for most workloads we evaluated, even with flows as small as 50 MiB, an improvement ...
To demonstrate the value of Planck's speed and accuracy, we use it to drive a traffic engineering application that can reroute congested flows in milliseconds. ...

This routing process has to be able to react on grid changes in a timely manner, i.e., it must be based on the instantaneous state of the grid. ...
The first approach is based on SDN; an ONOS SDN controller is used to change the behaviour of the communication infrastructure according to information provided by components of the power grid. ...
This way, real application layer routing is not possible, as SDN switches are able to route for example based on MAC, IP, TCP or user datagram protocol (UDP) header fields or some link information, but ...

Nevertheless, SDN research focuses very little on wireless communication and, more specifically, on Wireless Mesh Networks (WMNs). ...
However, routing rules do not change or update frequently in wired networks due to the static nature of network nodes, which results in no impact on the controller to switch connectivity. ...
