Patten (shoe) Patten (shoe) Pattens are protective overshoes that were worn in Europe from the Middle Ages until the early 20th century. Pattens were worn outdoors over a normal shoe, had a wooden or later wood and metal sole, and were held in place by leather or cloth bands. Pattens functioned to elevate the foot above the mud and dirt (including human effluent and animal dung) of the street, in a period when road and urban paving was minimal. The word "patten" probably derives from the Old French "pate" meaning hoof or paw. Women continued to wear pattens in muddy conditions until
Leaky bucket A limit on burstiness may be specified as a jitter or delay variation tolerance, or as a maximum burst size (MBS). Multiple sets of contract parameters can be applied concurrently to a connection using multiple instances of the leaky bucket algorithm, each of which may take a bandwidth and a burstiness limit: see Dual Leaky Bucket Controller. The rate at which the bucket leaks will determine the bandwidth limit, which is referred to as the average rate by Turner and the inverse of which is referred to as the emission interval by the ITU-T. It is easiest to explain what
