Patten (shoe) wooden inner sections with leather above and below. In earlier varieties of pattens, dating from the 12th century on, the stilt or wedge variety were more common. From the late 14th century, the flat variety became increasingly common. Leather pattens became fashionable in the 14th and 15th centuries, and in London appear to have begun to be worn as shoes over hose in the 15th century, spreading to a much wider section of the public. Most London patten soles were constructed of alder, willow or poplar woods. In 1390, the Diocese of York forbade clergy from wearing pattens and clogs
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
