Abstract: A method for managing network service response times by a client device is provided. The client device determines whether a network service of a service provider is reachable or active and determines a service response time of the service provider. The client device communicates to the service provider a request to establish a conditional connection based on an average accept service time of a connection and a maximum service response time.

Abstract: Embodiments include method, systems and computer program products for switching between interrupt context input/output I/O processing versus thread context I/O processing. The method includes receiving, by a processor of a plurality of processors, an interrupt. A device driver for an I/O adapter determines that the dispatch latency for an associated kernel thread is greater than a first predetermined threshold. An adapter switches to an interrupt context mode. The adapter processes an I/O on the processor associated with the received interrupt to completion.

Abstract: Methods, systems, and computer program products for two channel TCP are provided. Aspects include establishing a first TCP connection over a primary channel with a server, the primary channel having a first latency and a first bandwidth, establishing a second TCP connection over a secondary channel with the server, the secondary channel having a second latency and second bandwidth, establishing a first data stream with the server over the secondary channel at a first time period, and establishing a second data stream with the server over the primary channel during a second time period, wherein a start of the second time period is after the first time period.
