Packet reordering inside the Sprint backbone

In this paper we study the magnitude and causes of packet reordering in the Internet using data collected at a POP on the Sprint IP Backbone. We develop a methodology that uses TCP packet-level traces to infer the cause for reordering without the need of the complete TCP connection information (i.e. both data and acknowledgement paths). We classify reordering in two classes depending on the cau...

The “Staggering Switch”: An Electronically Controlled Optical Packet Switch

This paper presents an architecture and implementation issues of an “almost-all” optical packet switch that does not rely on recirculating loops for storage implementation. The architecture is based on two rearrangeably nonblocking stages interconnected by optical delay lines with different amounts of delay. We investigate the probability of loss and the switch latency as a function of link uti...
