    Abstract: Method and apparatus for evaluating the quality of a packet-switched voice connection. The apparatus includes measurement circuitry coupled to receive a voice signal. The measurement circuitry measures rate of packet loss and at least one other objective characteristic of the voice signal. The rate of packet loss and the at least one other objective characteristic are related to a plurality of quality characteristics affecting the quality of the voice signal as perceived by users, such that measurements of the rate of packet loss and the at least one other objective characteristic can be translated into subjective quantifications of each of the quality characteristics. A database stores an effects matrix. The effects matrix provides quality information for voice signals that include different combinations of subjective quantifications for each quality characteristic. Software operating on the apparatus utilizes measurements of the rate of packet loss and the at least one other objective characteristic and the effects matrix to generate quality information for the voice signal.

    Abstract: A computer implemented method includes encoding a packet in a source endpoint of a multi-path communication network, the packet having a hash seed for use by routers to route the packet through the multi-path communication network to a destination endpoint. Network performance is tracked for the packet at the source endpoint. The hash seed is modified as a function of the network performance. The packet is re-sent such that the modified hash seed is used to route the packet to the destination endpoint.

    Abstract: Provided are a screen casting data transmission method and apparatus, an electronic device and a storage medium. The screen casting data transmission method includes: receiving feedback information which is sent by a target data reception terminal according to received screen casting data, and determining a data round-trip time of the screen casting data according to information content of a preset data transmission field in transmission control protocol (TCP) header information in the feedback information; estimating a network bandwidth according to a value change of the data round-trip time, and determining an adjustment strategy for a screen casting data encoding parameter based on a network bandwidth estimation result and a current data sending bandwidth; and adjusting the screen casting data encoding parameter, encoding to-be-sent screen casting data according to the adjusted encoding parameter, and performing transmission.

    Abstract: This disclosure describes techniques for providing information associated with an inter-cluster segment. For instance, system(s) may determine dependencies for first services associated with a first cluster and second dependencies for second services associated with a second cluster. The system(s) may then determine information for interconnections between the first cluster and the second cluster. The information may include at least dependencies for third services included in the inter-cluster segment and/or performance information for the third services. The system(s) may then generate a user interface that includes the first dependencies for the first services, the second dependencies for the second services, and the information for the inter-cluster segment. This way, a user is able to use the user interface to identify both problems occurring within the clusters and/or problems that are caused by the third services in the inter-cluster segment.
