Abstract: Connectivity between remote networks is managed by a central engine that collects and stores network data such as network addresses, URLs, hostnames, and/or other information. The engine creates a tunnel proxy, as well as separate respective tunnels with the remote networks. Based upon network data, the engine references the tunnel proxy to create a logical link joining the respective tunnels. Data can then flow between the remote networks through the logical link. The logical link may exist for only a limited time, e.g., as determined by a timer. Certain embodiments may be particularly suited to empower a customer network to manage connectivity with the remote network of a support provider. The customer can initiate connectivity changes without the manual involvement of the support provider. The customer can also authorize the support provider to manage connectivity and initiate changes under prescribed conditions.

Abstract: The main object of the invention is a heat exchanger including a first header plate of an inlet manifold, a second header plate of a distribution header and a heat exchange core bundle extending between the first header plate and the second header plate along a longitudinal direction, the heat exchange core bundle being defined by a shell and having a plurality of tubes arranged successively next to each other in a transverse direction, each tube being capable of cooperating with the header plates via through-holes formed in each plate. The shell has at least one longitudinal end with a straight edge configured to be in flat surface contact with at least one header plate in a contact area, the surface contact occurring mainly in a plane perpendicular to the longitudinal direction.
