Unfortunately, it has been widely acknowledged that Ethernet does not scale well because it relies on broadcast, which wastes bandwidth, and a cycle-free topology, which poorly distributes load and forwarding ...
Although there are many different proposed designs, there is little data available that allows for comparisons between designs. ...
In a distributed architecture, every switch that requires forwarding table state for a route must independently compute and install forwarding table state. ...

In the proposed approach, the controller collects various traffic parameters from the switches and predicts the inter-arrival times of packets in a flow. ...
One of the main reasons why the controller suffers from this scalability problem is that it is fairly often overwhelmed by a large number of flow setup requests from the SDN switches to the controller. ...
This paper focuses on the scalability of a single SDN controller for enterprise networks and proposes a scheme that improves the scalability by reducing the communications between the switches and the ...

In this paper, we propose a scalable multicast solution on fat tree networks based on the observation that data center multicast traffic has strong heterogeneity. ...
However, traditional multicast protocols designed for IP networks are usually bottlenecked by the limited state capacity on switches. ...
For example, the controller computes four Steiner trees for an elephant group. The edge switch of a group member would store four rules for these trees. ...

This is certainly feasible for low port densities, but limits scalability. Moreover, he complexity of the packet placement process also limits system scalability. ...
