The 5G mobile communication networks are designed to allow new user experience for multimedia streaming services, which provides maximum data rates and minimum latency. However, existing multimedia service approaches in software defined networking (SDN) suffer from high delay, inefficient energy usage, and limited adaptability in dynamic network conditions, resulting in degraded quality of experience (QoE). The emerging architecture SDN offers flexibility, manageability and responsibility for rapid changes in traffic requirements. Hence, this research proposed a multimedia service approach in a 5G network-enabled Eel and Grouper Flamingo Search Algorithm (EGFSA). Firstly, the SDN simulation is executed through OpenFlow and Mininet as well as the energy model is performed. Secondly, the multi-path routing is efficiently done with the help of a new hybrid optimisation framework named EGFSA. The EGFSA model obtained delay, energy, bit error rate (BER), fitness and throughput of values 0.680 s, 37.270 J, 0.002, 0.872 and 32.477 Mbps, respectively.
