A system, a network node, a router, a method and a program used to determine a bottleneck bandwidth on a multi-hop path between a source and destination node is presented. The method comprises receiving probe packets by a first hop node in the multi-hop path, measuring a bandwidth on a link between the first hop node and a next hop node in the multi-hop path, generating a bandwidth discovery packet including the measured bandwidth, transmitting the BDP to the next hop node, relaying the probe packets to the next hop node, and determining if the next hop node is a last-hop node on the multi-hop path. A last hop node records the measured bandwidth from the BDP, adjusts the delay between the probe packets based upon the bandwidth and relaying the probe packets to the destination node. The destination node determines the bottleneck bandwidth based on the delay between the probe packets.

A line tap valve for tapping refrigerant lines of refrigeration and air conditioning systems, said line tap valve having a housing which is adapted to be clamped to a refrigeration line, said housing having two non-aligned but communicating valve bodies or chambers, a line piercing valve in one valve body or chamber and a service valve in the other valve body or chamber, said line piercing valve and said service valve being independently operable, to control the flow into and out of the refrigerant line. The service valve is removable and replaceable without refrigerant leakage when the line piercing valve is in closed position. The line piercing valve is retractable from the refrigerant line to provide an unimpeded flow therethrough when the service valve is in closed condition.

A fin comb for combing, straightening and cleaning fins of heat exchangers, such as fin-type condensers and evaporators used in refrigeration and air conditioning systems. The fin comb comprises a handle and a plurality of fin combing heads which are interchangeably mounted on the handle. The fin combing heads are provided with fin-shaped teeth of different thickness and spacing for engaging heat exchanger fins of different thickness and spacing. The fin combing heads are also reversible on the handle to adapt the fin comb to both pulling and pushing strokes relative to the heat exchanger fins. The fin combing heads are color coded for easy selection of the right size for the various heat exchanger fin assemblies which are normally encountered by refrigeration and air conditioning servicemen.
