Azion's Edge Network leverages Software-Defined Networking (SDN) to address the challenges of modern internet demands, providing scalable, efficient, and secure routing solutions that extend beyond the limitations of traditional protocols like Border Gateway Protocol (BGP). The Azion Edge Traffic Router is a key component, utilizing SDN to dynamically determine optimal routing paths based on real-time network data, enhancing performance and reducing latency by processing requests closer to users at distributed edge locations. This approach not only improves availability and fault tolerance but also includes robust security measures such as DDoS protection and collaboration with initiatives like MANRS to enhance routing security. By integrating SDN principles with BGP and employing a highly distributed architecture, Azion ensures intelligent content delivery and connectivity across the public Internet, optimizing traffic routing and minimizing operational costs while maintaining high service availability.

Border Gateway Protocol (BGP) was developed to manage communication between different Autonomous Systems (ASes) efficiently and has become integral to the complex and dynamic structure of the Internet, which necessitates specialized infrastructures for modern applications. Despite its significance, BGP faces several challenges such as routing table growth, inefficiency in reachability, memory management issues, lack of programmability, and slow route propagation, which are compounded by vulnerabilities like incorrect peering setups, route flapping, BGP manipulation, denial-of-service attacks, and route hijacking. Azion aims to address these issues by providing secure edge routing solutions, enhancing BGP's functionality through network programmability, and participating in initiatives like the MANRS Content Delivery Network to improve Internet routing security. Azion's Edge Traffic Router leverages real-time data to optimize routing paths, ensuring improved performance, reliability, and reduced latency, while their platform supports digital transformation through a comprehensive suite of products and global edge locations.
