The present invention may be configured to sequentially connect each port of an optical switch to a network port of a server and generate, based on information associated with network devices connected to the ports, a network map. The network map may identify which network devices are connected to which ports of the optical switch and may permit dynamic port mapping for network installation, upgrades, repairs, and/or the like. The present invention may also be configured to determine a fiber link in which a failure occurred and reconfigure the optical switch to allow communication between an optical time-domain reflectometer and the fiber link to test the fiber link.

A system includes multiple devices, multiple processors and a cross-network bridge. The cross-network bridge includes a bus interface for connecting to a system bus, and bridging circuitry configured to translate between (i) system-bus transactions that are exchanged between one or more local devices and one or more remote processors among the processors, the one or more local devices being coupled to the system bus and served by the system bus, and the one or more remote processors being located across a network from the cross-network bridge, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.

Mechanical thermal interface for improved heat dissipation in network transceivers
Apparatus for cooling an electro-optical (EO) device, the apparatus includes (i) a housing configured to encapsulate components of the EO device, including: a first portion including a substrate for supporting the components, and a second portion configured to connect with the first portion, the second portion having opening facing the components and shelf surrounding the opening, and (ii) a cooling assembly, includes a base plate configured to be removably fitted in the opening of the second portion, array of multiple c-shaped elements arranged in a face-to-back configuration on a first surface of the base plate, and a second surface of the base plate opposite the first surface, the second surface configured to face the components when the base plate is fitted in the opening, the base plate configured to transfer heat between the components and the c-shaped elements and has higher thermal conductivity than the second portion of the housing.
A networking device and system are described, among other things. An illustrative system is disclosed to include a congestion controller that manages traffic across a network fabric using receiver-based packet scheduling and a networking device that employs the congestion controller for data flows qualified as a large data flow but bypasses the congestion controller for data flows qualified as a small data flow. For example, the networking device may receive information describing a data flow directed toward a processing network; determine, based on the information describing the data flow, a size of the data flow; determine the size of the data flow is below a predetermined flow threshold; and in response to determining that the size of the data flow is below a predetermined threshold, bypass the congestion controller.
