Discuss the generic architecture of the OpenFlow switch with the appropriate diagram.

Expert Solution

OpenFlow Architecture:

The OpenFlow architecture contains 3 layers

Openflow virtual and physical switches
Openflow controllers
Openflow applications

The OpenFlow controller provides the OpenFlow protocol communications channels to the OpenFlow.

Switches, maintains a regional state graph of the OpenFlow switches and reveals a northbound API to the OpenFlow submissions. The northbound API may be viewed as an abstraction of the network and enables the OpenFlow applications to read the state of the network and to educate the network to perform various tasks.

A real world OpenFlow proficient network may comprise of only OpenFlow switches or a combination of OpenFlow switches and conventional switches and routers.

The latter network type is called an overlay network. Some OpenFlow applications will require only partial deployment of OpenFlow switches whereas others require a network consisting of only OpenFlow switches.

Deployment model:

The below diagram shows the deployment model of OpenFlow.

The diagram shows two loops of wire. The outerloop is a circuit with a switch, a battery, a capacitor (which starts out uncharged), and a resistor. The inner loop is just a wire. The two loops are not connected to each other electrically. https://scontent-iad3-1.xx.fbcdn.net/v/t1.15752-9/31963888_10211369349701547_3712409743130624000_n.jpg?_nc_cat=0&oh=10908d4f57a4ae22b17f20aefe6b43d9&oe=5B51BF2B a.

One of the assumptions made by economists is that firms maximise profits. Using appropriate diagram/s, discuss the long run and the short run profit maximization behaviour in a perfectly competitive market and in a monopoly. In your conclusion you should comment on whether a perfectly competitive market or a monopoly is better for society and why.
