Abstract:
Network overlays play a key role in the adoption of cloud oriented networks, which are required to scale and grow elastically and dynamically up/down and in/out, be provisioned with agility and allow for mobility. Cloud oriented networks span over multiple sites and interconnect using Virtual Private Network (VPN) like services across multiple domains. These connections are extremely slow to provision and difficult to change. Current solutions to support cloud based networks require combination of several protocols in data centers and across provider networks to implement end to end virtual network connections using different overlay technologies. However, they still do not necessarily meet all the above requirements without adding operational complexity or without new modifications to base protocols. This paper discusses a converged network virtualization framework called Cloudcasting, which is a single technology for virtual network interconnections within and across multiple sites. The protocol is based on minimal control plane signaling and offers a flexible data plane encapsulation. The biggest challenge yet for any virtual network solution is to distribute and inter-connect virtual networks at global scale across different geographies and heterogeneous infrastructures. Data center operators are faced with the predicament to re-design networks in order to support a specific virtualization approach. Cloudcasting technology can be easily adopted to interconnect or extend virtual networks with in a massive scale software defined data centers, campus networks, public, private or hybrid clouds and even container environments with no change to physical network environment and without compromising simplicity
