As shown in the previous figure, the OpenVolcano physical architecture is composed of the following building blocks:
OpenFlow Switch (virtual) - Quake: Software OpenFlow switch implemented according to the OF 1.3 specification. The switch connects the Virtual Machines (VMs) hosting the Service_Apps and the Network Functions (NFs) hosting the Net_Functions among them and to the external network.
Virtual Machines: Virtual Machines (VMs) are the execution environments for the Service_Apps chains.
Network Functions (NFs): NFs are software instance residing on servers. They provide network services such as firewall or NAT. The firewall and NAT NFs are part of the Cone module.
Servers: The servers run the Virtual Machines, the Network Functions and one instance of the Quake switch.
OpenFlow switches (physical): Connect the servers via the Quake switches.
