  • Method and system for detection of aliases in a network
    Patent number: 7698561
    Abstract: The invention provides a method and system of detecting aliases in a network. The network comprises at least one device and at least one Network management system (NMS) for managing the devices. The NMS identifies each device available in the network with a message digest. The NMS retrieves the message digest of a device that is submitted for management. The NMS tries to locate the retrieved message digest with a database of message digests. In case the retrieved message digest is located on the database, the NMS declares the device as an alias. However, if the message digest is not located on the database, the NMS stores the message digest in the database and starts managing the device.

  • Converting a network device from data rate traffic management to packet rate
    Patent number: 7672244
    Abstract: A network device that manages the flow rate of a stream of packets traveling within a network is converted from managing based on data rate to managing based on packet rate. In one embodiment, an interface receives from the device an actual length of a packet and provides to the device an effective length for the packet. A multiplexer generates the effective length by selecting the actual length during data rate mode and selecting a virtual length during packet rate mode. Various embodiments work with network devices that use various traffic management techniques. Such techniques include, but are not limited to: virtual time algorithms for determining excess packets; policing techniques that drop excess packets; and shaping techniques that buffer excess packets for possible later transmission.
