Abstract: A peer-to-peer (P2P) probing/network quality of service (QoS) analysis system utilizes a UDP-based probing tool for determining latency, bandwidth, and packet loss ratio between peers in a network. The probing tool enables network QoS probing between peers that connect through a network address translator. The list of peers to probe is provided by a connection server based on prior probe results and an estimate of the network condition. The list includes those peers which are predicted to have the best QoS with the requesting peer. Once the list is obtained, the requesting peer probes the actual QoS to each peer on the list, and returns these results to the connection server. P2P probing in parallel using a modified packet-pair scheme is utilized. If anomalous results are obtained, a hop-by-hop probing scheme is utilized to determine the QoS of each link. In such a scheme, differential destination measurement is utilized.

Abstract: The apparatus comprises a steel belt (5) extending according to an endless strap around two guide rollers (3, 4) driven in rotation according to horizontal axes. The upper part of the belt (5) defines a first going stretch (5a) onto which the product (6) in progress of working is laid, said product being transported due to the movement communicated to the belt as a result of the rotation of said guide rollers. Water is sprayed against the underneath surface of the first belt stretch for cooling the product through a heat exchange with the belt itself. The apparatus further comprises a heat exchange roller (14) rotatably supported according to a horizontal axis and arranged so that it comes in contact with the product (6) located on the first belt stretch (5a). Water circulation takes place within the heat exchange roller (14) and an additional cooling action is therefore accomplished on said product (6).
