Load sharing in multi-access systems
In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level (130-133) based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level (130-133). Communication utility can preferably be maximized or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads. |

Media acceleration for virtual computing services
Streaming media is problematic for thin clients using remoting protocols like RDP that were never designed to handle the volume of data associated with multimedia. The result is large demands on the host computer and thin client CPU and excessive bandwidth on the network, which results in a poor display quality. A process running on a host computer detects an existing multimedia acceleration channel to a thin client and also identifies unaccelerated media streams like Adobe Flash. The unaccelerated content is automatically re-encoded using a codec format supported by the thin client acceleration channel. This results in a significant improvement in the quality of the streaming media displayed on the thin client and overall reductions in host CPU load, network bandwidth and thin client CPU load. No additional software is required on the thin clients to support new media types including Adobe Flash. |

System and method of arbitrating access to interconnect
Aspects relate to arbitrating access to an interconnect among multiple ports.

Increasing performance of a streaming application by running experimental permutations
A streams manager monitors performance of a streaming application, and when the performance needs to be improved, the streams manager automatically requests virtual machines from a cloud manager. In response, the cloud manager provisions one or more virtual machines in a cloud.

When the performance of the permutation exceeds the performance of the original part of the flow graph, the streams manager modifies the flow graph so the permutation replaces the original part of the flow graph. In this manner a streaming application can dynamically evolve to increase its performance as needed. |
