Abstract: Exemplary embodiments for use in a communications source network node for identifying a destination port associated with a destination network node to which a selected network link is connected. The embodiments include receiving a communications protocol packet at a destination network node via said selected network link connected to the destination port associated with the destination network node; inspecting the packet for a predetermined identifier; and if the predetermined identifier is present in said packet then outputting an indication that the identifier has been received comprising an identification of the destination port via which the packet was received. The indication is output by at least one of illumination for a pre-set period of a destination switch associated with the destination port, and by an output provided via a user interface of a network interface controller associated with the destination port.

Abstract: A system for use in a computer network is disclosed for identifying the destination of a network link from a source of the link, in which a predetermined identifier is transmitted between the connected network nodes.

Abstract: According to embodiments of the invention, there is provided a computer program product, a method, and a system to clean an image produced by the system. A digital canvas representation of an initial condition is produced. A set of real-time digital information is captured to form an unconstrained digital representation of the set of real-time digital information. A constraining digital mask based on the digital canvas representation of the initial condition is applied to the unconstrained digital representation of the set of real-time digital information to form a constrained digital representation of the set of real-time digital information. The constrained digital representation of the set of real-time data is stored, allowing an application program to use the constrained representation of the real-time data.
