Description: Today’s Internet often suffers transient outages, but as increasingly critical services migrate to the cloud; much higher levels of Internet availability will be necessary. The stunning shift toward cloud computing has created new pressures on the Internet.  Loads are soaring, and many applications increasingly depend on real-time data streaming. Unfortunately, the reliability of Internet data streaming leaves much to be desired. Here, we focus on routing in the Internet’s core, at extremely high data rates (all-to-all data rates of 40 Gbits per second are common today, with 100 Gbits/s within sight). These kinds of routers are typically implemented as clusters of computers and line cards: in effect a data center dedicated to network routing. The architecture is such that individual components can fail without bringing the whole operation to a halt. . For example, network links are redundant; if one link fails, there will usually be a backup. Such a router could even run routing protocols of different type’s side by-side, making the actual routing decisions by consensus — if some protocol instance malfunctions, its peers would simply outvote it. But suppose that a routing protocol (for clarity, we focus on the Border Gateway Protocol [BGP], implemented by a BGP daemon [BGPD] hosted on some node within the router) needs to be restarted after a crash or updated with a software patch or migrated within the cluster.
