Although the Internet is widely used today, we have little information about the edge of the
network. Decentralized management, firewalls, and sensitivity to probing prevent easy …

The performance of a backbone network is vulnerable to interdomain routing changes that
affect how traffic travels to destinations in other Autonomous Systems (ASes). Despite …

IP addresses are commonly used to identify hosts or properties of hosts. The address
assigned to a host may change, however, and the extent to which these changes occur in …

Routing dynamics heavily influence Internet data plane performance. Existing studies only
narrowly focused on a few destinations and did not consider the predictability of the impact …

Most conventional IPv4-based route lookup algorithms are no more suitable for IPv6 packet
forwarding due to the significantly increased 128-bit-long address. However, as a result of …

• DZs do normal routing on site prefixes (CIDR allocation, but portable across providers);
unknown prefixes are routed to DFZ• when packet hits fist DFZ router, destination site prefix …

The notion of Internet Policy Atoms has been recently introduced in [1],[2] as groups of
prefixes sharing a common BGP AS path at any Internet backbone router In this paper we …

It is well-known that simple, accidental BGP configuration errors can disrupt Internet
connectivity. Yet little is known about the frequency of misconfiguration or its causes, except …

Recent work in network traffic matrix estimation has focused on generating router-to-router
or PoP-to-PoP (Point-of-Presence) traffic matrices within an ISP backbone from network link …

There is striking volume of World-Wide Web activity on IPv6 today. In early 2015, one large
Content Distribution Network handles 50 billion IPv6 requests per day from hundreds of …
