Abstract

BGP is the de facto protocol used for inter-autonomous system routing in the Internet. Generally speaking, BGP has been proven to be secure, efficient, scalable, and robust. However, with the rapid evolving of the Internet in the past few decades, there are increasing concerns about BGS's ability to meet the needs of the Internet routing. There are two major limitations of BGP which are its failure to address several key security issues, and some operational related problems. The design and ubiquity of BGP have complicated past efforts at securing inter-domain routing. This paper surveys the past work related to BGP security and operational issues. We explore the limitations and advantages of proposed solutions in these two limitations.
