  • Patent number: 8711713
    Abstract: Systems and methods for sinking port mirrored from one or more identified flows of data to any node in a network are provided. Moreover, the network is configured to convey the mirrored data to the sink, without the need for any facilities expressly dedicated for this purpose. The present invention removes the requirement to co-locate the sink port within the same logical node. The present invention uses a mirrored flow configured as a provisioned layer two point-to-point connection, such as a Switched Permanent Virtual Circuit (SPVC), Pseudo-Wire (PWE3), a Virtual Local Area Network (VLAN) cross-connect, Provider Backbone Bridging-Traffic Engineering (PBB-TE), and the like. The node with the mirrored port is configured to create copies of the appropriate set of packets (i.e., ingress, egress packets, or both based on provisioning and based on the identified flow), and to forward the packets to the sink port through the provisioned point-to-point connection.

  • Patent number: 7137074
    Abstract: The invention provides an improved automated system and method for monitoring the states of other systems. In one embodiment, the inventive system and method may be employed by an operations console that is monitoring the state of one or more data processing systems. According to the invention, a set of states is defined to describe events or conditions occurring within the monitored systems. A set, or “family”, of files is defined, wherein the family includes an associated file for each of the defined states. When one or more of the monitored systems are determined to be in a predetermined state, data signals stored within the associated file may be used to generate some type of signal that may be readily perceived by the operator to determined the state. For example, the data signals may be used to generate a visual or audio representation of the state.

  • Publication number: 20020057822
    Abstract: Planar magnetic acoustic transducer diaphragms are formed from an electrical non-conducting membrane and metallic layer laminate by selectively removing portions of the metallic layer to create at least one electrical conductor circuit pattern and at least one passive metallic area both of which are of a predetermined size and configuration to balance modal behavior of the diaphragms when in use.
