摘要： A method of generating an annotated network topology of a network is described. The method includes; deriving a network topology by performing a route tracing utility between each pair of endpoints to determine the route taken by packets; initially annotating each network path with an initial value; determining the available bandwidth of a path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints; identifying a bottleneck link in the network path, and annotating all edges to generate an annotated network topology wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements.

摘要： A method is used in managing read caching. First and second read caches are maintained in a data storage system. The first read cache is controlled by a first storage controller and the second read cache is controlled by a second storage controller. Read cache data is copied from the first storage controller to the second storage controller. A failure of the first storage controller is detected. Based on the detection, the copied read cache data is processed at the second storage controller to make the copied read cache data available for use at the second storage controller.

摘要： A method of detecting rogue devices that are coupled to a wired network without generating false negative or false positive alerts is provided. When a wireless monitor detects an observed SSID and/or BSSID, various tests are run to determine whether the observed device is actually coupled to the wired network. To guard against the suspect device spoofing an authorized SSID and/or BSSID, location information is gathered so that the network administrator can pinpoint the location of the rogue device. If the device is not recognized, various other tests are run to determine whether the unrecognized device is actually connected to the wired network. These tests include an association test, a MAC address test, an ARP test, a packet replay test, a correlation test, and/or a DHCP fingerprint test. Once it is determined that the suspect device is a rogue connected to the wired network, an appropriate alert is generated.
