The paper "SSED: Servers Under Software-Defined Network Architectures to Eliminate Discovery Messages" by Emad Alasadi and Hamed S. Al-Raweshidy addresses the scalability issues in Ethernet networks, particularly due to broadcast and multicast mechanisms. The authors propose a novel approach called Servers under Software-defined network architectures to Eliminate Discovery messages (SSED) to overcome these limitations. SSED introduces a floodless packet backbone in an SDN LAN network, eliminating broadcast discovery packets and improving performance. The paper discusses the current challenges of Ethernet networks, such as broadcast storms, increased network traffic, and security vulnerabilities, and proposes SSED as a solution. SSED uses a Multi-To-One (MTO) collective service method to forward packets directly to specific servers, reducing the number of rules in switches and improving efficiency. The paper also details the implementation of SSED, including its mechanisms for handling ARP and DHCP broadcast messages, and provides experimental results demonstrating its effectiveness in improving scalability, reducing peak overhead, and enhancing security. The testbed results show that SSED outperforms legacy switches in terms of response time, control packet reduction, and overall network performance.The paper "SSED: Servers Under Software-Defined Network Architectures to Eliminate Discovery Messages" by Emad Alasadi and Hamed S.
