Dr. Zakaria Al-Qudah, an Associate Professor of Computer Engineering at Yarmouk University, has received a US patent from United States Patent and Trademark Office (USPTO) joint with other inventors titled "Multi-Autonomous System Anycast Content Delivery Network". This invention allows anycast content delivery networks to work across multiple autonomous systems instead of having to be confined within a single autonomous system. Anycast content delivery networks directs users to closer edge servers than those selected by DNS-based content delivery networks since they base the request routing decision on the location of the client itself rather than the location of the client's local DNS server.
