The present invention describes a system and method of OAM diverse signal processing using classical beams for applications in which OAM signal character is controlled such as optical tagging and applications in which OAM signal character is not controlled such as clutter mitigation and interference cancellation for target detection, identification etc. This is accomplished by transmitting a source beam having a prescribed state with one or more non-zero OAM components, reflecting the beam off a ‘tagged’ or ‘untagged’ target and receiving the return beam in the direct return path to measure the one or more OAM components to identify the target. OAM processing provides additional degrees of processing freedom to greatly enhance the processing capabilities to detect and identify both ‘tagged’ and ‘untagged’ targets.

Furcation tubing is made of glass-filled Teflon (PTFE) that provides reduced longitudinal shrinkage and increased tensile bond strength in the standard colors utilized for fiber identification. The furcation tubing experiences no more longitudinal shrinkage than furcation tubing made of polyvinylidene fluoride (PVDF) and has a tensile bond strength no less than furcation tubing made of clear, etched Teflon (PTFE). A fanout furcation kit prevents movement of the separated optical fibers in a funnel area of a lower furcation body. The funnel area is bathtub shaped with an increasing depth in the direction of an insert block having at least two rows of passageways in a staggered array. Guide walls defining the funnel area form a seal with an upper furcation body. Use of the furcation tubing and fanout furcation kit significantly reduces unacceptable attenuation and micro-damage to optical fibers deployed in an outdoor fiber optic network.

An embodiment system and method to provide rack awareness for a virtual machine running on a data center server. The virtual machine sends an address resolution protocol request message to a top-of-rack switch to identify a MAC address of the server physical port. The virtual machine receives a reply containing the MAC address of the top-of-rack switch physical port. The virtual machine sends an ICMP packet to the top-of-rack switch with a pre-selected un-routable IP address using the identified physical port MAC address. The virtual machine then receives a message from the top-of-rack switch providing a top-of-rack IP address. The virtual machine employs the top-of-rack IP address to identify the rack location of the server.

Regardless of the failure, the computer system can be operated without changing processing capability thereof. The controller can monitor load of each operating system to allocate computer resources to the operating system according to the load.
