Abstract: A method for allocating network resources among a set of real-time video flows to maximize a total measured quality of experience (QoE) including detecting a state change, determining whether a state network resource allocation can be optimized after the state change, where the determining compares an output utility value of a utility function over the set of real-time video flows to a current utility value of the network resource allocation, and selecting an optimal network resource allocation indicated by the utility function, in response to determining the state change can be optimized.

Abstract: A method performed by a base station includes receiving a data stream comprising a sequence of packets and detecting a packet of the sequence of packets is a restart packet. The base station determines that one or more packets of the sequence of packets is buffered for transmission in front of the restart packet. The base station removes the one or more packets in front of the restart packet from the buffer and transmits the restart packet and at least one packet in the sequence of packets that follows the restart packet.

Abstract: A method is provided that is implemented by a computing device to automate management functions in a network. The method collects existing state of the network from local database tables, logs or remote system tables. An expected network state is generated from a predefined set of expectations. The expected network state is compared to the collected existing state to identify errors in the network. The method then generates a set of notifications for administrators for the identified errors.

Abstract: A method of reserving lookup keys in a computer communication system including a hierarchy of key manager nodes includes receiving a first reservation request at a first key manager node at a first level of the hierarchy of key manager nodes. The first reservation request requests reservation of a lookup key. The methods include determining whether or not the first key manager node has authority to grant the reservation request, and, in response to determining that the first key manager node does not have authority to grant the reservation request, sending a second reservation request requesting reservation of the lookup key to a second key manager node that is at a second level of the hierarchy of key manager nodes.

Abstract: Systems/methods of looking up an address of a target server include receiving a first lookup request at a first lookup server that manages a first database that contains data relating to a first plurality of servers. First metadata relating to the target server is retrieved from the first database, and a second lookup request including the first metadata is sent to a second lookup server that manages a second database that contains data relating to a second plurality of servers. The second plurality of servers is a subset of the first plurality of servers and includes the target server. Second metadata relating to the target server is retrieved from the second database, and a response based on the first and second metadata is transmitted to the client. Corresponding systems/methods of binding a server address to a lookup key are also disclosed.
