These networks deliver critical information with required quality of service in the presence of changing operational priorities. When compared to traditional tactical networks, SDN-enabled tactical networks offer benefits such as configurability, which provides the ability to configure the network without re-engineering of the hardware and agility, which provides the ability to re-configure the network quickly and easily with minimal resources. SDN is based on OpenFlow protocol which is a standard for remotely programming the forwarding plane of the network devices. OpenFlow protocol overtly specifies protocol headers on which it operates and these headers have been growing with each newer version of OpenFlow. The increase of headers has endorsed the complexity of the OpenFlow specification without offering flexibility to add new headers. This work analyse the Programming Protocol-Independent Packet Processor (P4) alongside OpenFlow to enable flexibility and protocol-independence without being tied to any specific network protocol in SDN. Most importantly, the use of P4 alongside OpenFlow for SDN tactical networks is highlighted.enSoftware defined networkingSDNTactical networksConference PresentationNkosi, M. C. (2018).
