Software Defined Networking is seeing a lot of momentum these days. With server virtualization solving the virtual machines problem, and large scale object storage solving the distributed storage challenge, SDN is seen as key in virtual networking.
In this talk we don't try to define SDN but rather dive straight into what in our opinion is the core enabled of SDN: the virtual switch OVS.
OVS can help manage VLAN for guest network isolation, it can re-route any traffic at L2-L4 by keeping forwarding tables controlled by a remote controller (Openfow controller). We show these few OVS capabilities and highlight how they are used in CloudStack and Xen.
