Threaded connections are provided with a thread form that permits the construction of enlarged root radii between adjacent threads. Relatively coarse thread leads formed along conical surfaces with relatively extended tapers cooperate with relatively tall thread heights and an enlarged root radius (or radii) to produce a fatigue resistant, rotary-shouldered connection that can be assembled with reasonably attainable high torque forces. The ratios between the thread lead, measured in threads per inch, as the numerator, and denominators comprising the untruncated thread height of the thread, and / or the root truncation and / or the root radius (or radii) are maintained at low values compared to those existing in conventional prior art connections. The ratio of the untruncated thread height to the root radius (or radii) is also retained at a relatively low value as compared to that existing in many prior art configurations. The connection design produces an unexpectedly high resistance to fatigue damage or failure. The connection may be employed in any rotary-shouldered connection and is particularly effective in preventing fatigue damage in the stiffer components of drill stem assemblies including single shoulder and double shoulder drill collar connections.

In a multiple element network, a method and network element for providing a constraint based routing system to accommodate non-transitive exceptions. The method and network element receive a connection request for an end to end connection. The network element can select routing information having a pair of adjacent links associated with the multiple elements of the network, where each link of the pair of links has a shared network resource. The shared network resource is compared to a database of exception sets, the exception sets including at least one non-transitive exception predetermined from a plurality of network resources. The network element confirms whether the shared network resource of the selected pair of links is contained within the exception database.
