  • Method and system for path selection in a network
    Patent number: 8619555
    Abstract: Method and system for handling error events on a current path for processing an I/O request for reading information from and writing information to a storage space is provided. A system is able to communicate with the storage space via more than one path. If the current path reports an error event, then an alternate path quality is determined to ascertain whether the alternate path will generate an error similar to the current path. The alternate path quality is determined based on a plurality of factors which are assigned certain weights. The weights are determined based on a likely contribution of each factor to a repetition of the error reported by the current path. If the alternate path quality is equal to or exceeds a programmable threshold value, then the alternate path is selected.

  • Reputation-based networking
    Patent number: 8570861
    Abstract: When one actor or network within a broader system of networks is announcing numerous routes or otherwise performing “poorly,” the neighboring networks can suffer because of the strain that the poorly performing network puts on resources. Typically, in order to counteract the effects of a poorly performing neighboring network, a router may simply stop accepting changes or stop accepting packets from the poorly performing neighbor. Some network participants may only temporarily be acting poorly and straining its neighbors' resources, however. Therefore, in some of the embodiments, a reputation score or level for a network participant may be determined based on its actions over time. This reputation may be used to determine whether, when, and how to act on the network request from the participant.

  • Method and arrangement for activity detection in a telecommunication system
    Patent number: 8570924
    Abstract: The present invention relates to a method and arrangement for efficient use of network resources, in particular for continuous connectivity services. The present invention introduces a set of established rules for uplink and/or downlink activity detection such that a Node B and/or a UE is enabled to detect active and inactive transmission periods on links for reception of packet data transmission and can independently arrange for inactivity/activity state transitions without any need of further signalling. Such a set of rules can be communicated to the Node B and the user equipment, e.g., from the radio network controller (RNC), or can consist of a predefined set of fixed rules that is readily implemented in said units.

  • Network routing metering
    Patent number: 8559324
    Abstract: Systems, methods, and computer-readable media for network routing metering are disclosed. In some embodiments, various changes to the routes, and other actions requested by a computer system, physical or virtual, can be metered. Those actions may be performed and later rated in order to determine what amount, if any, to charge an account associated with the requesting network participant system. The network participant system can be billed based on the activities performed on its behalf. Therefore, even if a network is performing poorly and requires more resources that would normally be allowed by a neighboring router, if the network owner pays to have these requests performed, then the embodiments herein can allocate more resources to supporting the network's rapidly changing network.
