Back-of-the-Envelope Computation of Throughput Distributions in CSMA Wireless Networks
— This paper presents a simple method for computing throughputs of links in a CSMA network. We call our method back-of-the-envelop (BoE) computation, because for many network con...

A Queueing Model Framework of PCE-Based Inter-Area Path Computation
Abstract—Path computation elements (PCE’s) are used to compute end-to-end paths across multiple areas. Multiple PCE’s may be dedicated to each area to provide sufficient path...
