Abstract
We propose a novel congestion control protocol, WindowTree, that adapts existing congestion control concepts found in TCP New Reno to the receiver driven content centric context. WindowTree also includes an Explicit Congestion Notification (ECN) mechanism by which the network can deliver early information about increasing congestion to the receiver, allowing the receiver to adjust accordingly to provide more efficient transfers. The protocol utilizes information about the network topology delivered through the use of route labeling, in which individual network nodes identify themselves and their relative layouts to the receiver. The WindowTree protocol maintains a tree of congestion windows derived from this topology information that enables it to adapt its behavior in response to network changes that affect each individual network source. Route labeling and shared congestion windows, combined with ECN marking, allows WindowTree to drastically reduce loss and more fully fulfill the requirements of a network dominated by the multipath data flows that exist in a CCN.
