Abstract: Systems, methods, and computer program products are disclosed for dynamically determining an optimal node of an overlay network for client attachment. An optimal node can be selected from a group of potential attachment nodes in the overlay network through which a client can establish a connection to the overlay network. Network parameter training data can be determined and used to train a network optimization model. Once trained, the network optimization model can be used to determine—based on network parameter data associated with the group of potential attachment nodes—the optimal node for the client to attach to. If a different node than a current attachment node is determined to be a new optimal node, a connection path can be established between this new optimal node and the client, and an existing connection path between the client and the previous optimal node can be terminated or simultaneously maintained.

Abstract: Status information associated with a set of cloud servers is received. Each cloud server in the set has an associated cloud agent, and the status information includes available computing resources and associated resource compensation information. Aggregated status information is determined for the one or more cloud servers, and the aggregated status information is forwarded to one or more of the cloud agents. A request for performing a computation is received in which the request includes a request specification. A selected cloud agent associated with one or more cloud servers most likely to accept the request based upon the aggregated status information and request specification is determined.

Abstract: Embodiments are directed to a computer-implemented method of optimizing performance of a computer network. The method includes receiving a request to transmit data from a first location. For each path in a set of paths, where each path comprises a connection allowing the transmission of data from the location, a set of performance measures for the path is determined. For each path in the set of paths, an incremental cost of transmitting the requested data using the path is determined. Thereafter, the performance measures and incremental cost for each path is used to determine which path to use to transmit data. Data is then transmitted using the determined path using multipath transmission control protocol techniques (MP-TCP).

Abstract: A method includes configuring worker services to operate in a stateless manner and providing support services that enable the worker services to operate in the stateless manner. The support services include (i) a management service for providing notifications of server removal and addition, (ii) a state maintenance service for maintaining state information in a central location, and (iii) a load balancer service for distributing requests among worker services. The method includes altering a number of servers allocated to at least one worker service, responsive to a notification from the management service. A private protocol is used between the worker services and load balancer service (a) to send, from the worker services to the load balancer service, a respective pointer to the state information associated with the requests, and (b) to include the respective pointer in the requests when any of the requests are forwarded to any worker service.

Abstract: A method is provided of using a set of servers to provide deferential services that have a pre-negotiated time for notice to release the servers. The method includes defining a virtual checkpoint frame interval that is constrained to a duration of up to half of the pre-negotiated time for notice to release the servers. The method includes collecting packets and transactions occurring during the interval that are processed by a current server. The method includes, responsive to an end of the interval, (i) writing, to a shared state database, a state of processing of the packets and transactions occurring during the interval, and (ii) releasing the packets and transactions occurring during the interval. The method includes copying the packets and transactions occurring during the interval, and the state, from the current server to another server for subsequent processing, responsive to an indication of an instance loss on the current server.

Abstract: A downstream element in a pipeline processing a network flow receives a first request and executes an indexing function to compute an index into a control block for storing state information associated with the data packet. The downstream element transmits a request to an upstream element to include the index as a tag in one or more subsequent data packets that comprises the plurality of network fields and the associated values. Subsequent data packet may be received at the downstream element with the tag having the index information. The downstream element may process the subsequent data packet based on the tag without having to execute the indexing function on the subsequent data packet.

Abstract: An approach is provided for managing an allocation of a bandwidth of a dedicated channel in a network being utilized by an application performing a replication of data from a first to a second storage resource. Checks of parameters specified by the application are determined. The parameters include, but are not limited to, average compression ratio, compression ratio trend, throughput, throughput trend, and round trip time. Respective high and low threshold values for the parameters are determined. At least one of the checks of the parameters is executed, which determines a violation of a threshold value for one of the parameters. If the violation of the high threshold value is determined, an increase in the bandwidth is triggered. If the violation of the low threshold value is determined, a decrease in the bandwidth is triggered.
