Explaining BGP Slow Table Transfers
Although there have been a plethora of studies on TCP performance in supporting of various applications, relatively little is known about the interaction between TCP and BGP, which is a specific application running on top of TCP. This paper investigates BGP's slow route propagation by analyzing packet traces collected from a large ISP and RouteViews Oregon collector. In particular the authors focus on the prolonged periods of BGP routing table transfers and examine in detail the interplay between TCP and BGP. In addition to the problems reported in previous literature, their study reveals a number of new TCP transport problems that collectively induce significant delays.
