Disjoint-Path Selection in Internet: What traceroutes tell us?

Sameer Qazi, Tim Moors

Routing policies used in the Internet can be restrictive, limiting communication between source-destination pairs to one path, when often better alternatives exist. To avoid route…

Finding Alternate Paths in the Internet:A Survey of Techniques for End-to-End Path Discovery

Sameer Qazi, Tim Moors

The Internet provides physical path diversity between a large number of hosts, making it possible for networks to use alternative paths when one path fails to deliver the required…
