New‐Generation Protocols
Guy Pujolle · 2015
Protocols are currently undergoing numerous mutations, owing to the advent of the Cloud and of SDN architectures. The legacy protocols based on routing of IP packets and MPLS (MultiProtocol Label Switching) are still in place for the connection of users or data transport, offered by the major operator networks. The protocol cited most at present is TRILL (Transparent Interconnection of Lots of Links). TRILL is a level-2 Ethernet network with extensions to facilitate routing in a level-2 Ethernet environment. This chapter discusses OpenFlow protocol, it has two parts: the part that contains the queues, the frame transmitters and the frame receivers and the second part which governs communication with the controller using the OpenFLow signalling protocol. The chapter examines a certain number of protocols for the Cloud and more specifically for interconnecting datacenteres.
