Trusted execution environment virtual machine cloning
Cloning of a virtual machine having a trusted executed environment such as a software-based trusted platform module. In order to clone the virtual machine, the virtual machine state of the source virtual machine is copied to formulate a target virtual machine state that is to be associated with a target virtual machine. The target virtual machine is a clone of the source virtual machine state, and thus the storage hierarchy of the trusted execution environment may be the same for the trusted execution environment in the source and target virtual machine states. However, because the identity of the target virtual machine is different than that of the source virtual machine, the endorsement hierarchy of the target virtual machine state is altered such that it is based on the identity of the target virtual machine, rather than the source virtual machine. |

Automatically redirecting method calls for unit testing
A unit testing system allows testing of multiple types of method calls using an unmodified software application module. The system dynamically copies byte code of the tested method, clones the byte code, and executes the cloned byte code. During cloning, the system instruments the code so that method calls are redirected into a system method, where the system can determine whether a mocked method should be called instead. The result is that the developer does not need to modify the original methods in order to redirect method calls to mock methods. The developer can simply reference a test module of the unit testing system and easily write tests that redirect any method they wish. Thus, the unit testing system provides a framework for building more useful unit tests that cause less interference with production-ready code. |

Agent conferenced IVR
A system engages a live agent in a multi-party call type arrangement with the user and an Interactive Voice Response (IVR) unit when the user has difficulty with the IVR. The agent is provided with information about the IVR process being executed and the user's input. When the agent is introduced into the call, the agent does not take over the IVR session, but the agent helps direct the user to provide the correct input(s) to the IVR session. Once the issue is corrected, the agent can remove themself from the customer/IVR dialog. As a consequence: the user continues their self-service transactions in the IVR, and the user is better educated on how to navigate the IVR in the future. Further, agent resources are spared from further interaction with the user, and the user is less likely to have a negative opinion of the IVR. |

Network routing using indirect next hop data
A router maintains routing information including (i) route data representing destinations within a computer network, (ii) next hop data representing interfaces to neighboring network devices, and (iii) indirect next hop data that maps a subset of the routes represented by the route data to a common one of the next hop data elements. In this manner, routing information is structured such that routes having the same next hop use indirect next hop data structures to reference common next hop data. In particular, in response to a change in network topology, the router need not change all of the affected routes, but only the common next hop data referenced by the intermediate data structures. This provides for increased efficiency in updating routing information after a change in network topology, such as link failure. |

Predictive network services load balancing within a network device
In general, techniques are described for performing load balancing across resources of a network device. In one example, upon receiving an initial packet, a load balancer module of the network device is configured to perform a lookup in a routing table based on a subscriber identifier associated with the initial packet, and determine whether a line card is pre-assigned to process the initial packet based at least in part on the lookup result. A packet forwarding engine is configured to when one of the line cards is pre-assigned, direct the initial packet to the pre-assigned line card, and, when one of the line cards is not pre-assigned, dynamically identify one of the line cards to process the initial packet based at least in part on header information of the initial packet, and direct the initial packet to the dynamically identified line card. |

Dynamic optimization of a multicast tree hierarchy for a distributed switch
A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. Moreover, each surrogate may optimize the hierarchy according to one or more optimization criteria. For example, each surrogate in the hierarchy may have the necessary information to ensure that if the next surrogate in the hierarchy is unavailable, the data may be routed to a backup surrogate. The selected hierarchy may be further optimized by skipping surrogates (or a surrogate level) such that the data intended for a skipped surrogate is sent to a surrogate in a lower-level of the hierarchy. This may better utilize the connection interfaces in the transmitting sub-switches and eliminate any unnecessary surrogate-to-surrogate transfers. |

Packet-data-network-specific addressing solutions for clients relying on proxy-based mobility
A wireless client terminal includes an application module, a service mapping module, and an address determination module. The application module determines first and second services requested by applications. The service mapping module stores a table that maps services to access point names. Each access point name identifies a respective packet data network. The address determination module transmits an address request message, including access point names corresponding to the services, to a media access gateway and receives an address response message. The address determination module determines first and second addresses based on address information in the address response message. The application module transmits a first packet to the media access gateway. The source address of the first packet is set to the first address when the first packet is related to the first service and to the second address when the first packet is related to the second service. |
