Anypoint: Extensible Transport Switching on the EdgeKenneth G. Yocum, Darrell C. Anderson1, Jeffrey S. Chase, and Amin M. Vahdat
Abstract:Anypoint is a new model for one-to-many
communication with ensemble sites--aggregations of end nodes that appear
to the external Internet as a unified site. Policies for routing Anypoint
traffic are defined by application-layer plugins residing in extensible
routers at the ensemble edge. Anypoint's switching functions operate at
the transport layer at the granularity of transport frames. Communication
over an Anypoint connection preserves end-to-end transport rate control,
partial ordering, and reliable delivery. Experimental results from a
host-based Anypoint prototype and an NFS storage router application show
that Anypoint is a powerful technique for virtualizing and extending
cluster services, and is amenable to implementation in high-speed switches.
The Anypoint prototype improves storage router throughput by 29% relative
to a TCP proxy.
