System and method for cooperative virtual machine memory scheduling
A resource scheduler for managing a distribution of host physical memory (HPM) among a plurality of virtual machines (VMs) monitors usage by each of the VMs of respective guest physical memories (GPM) to determine how much of the HPM should be allocated to each of the VMs. On determining that an amount of HPM allocated to a source VM should be reallocated to a target VM, the scheduler sends allocation parameters to a balloon application executing in the source VM causing it to reserve and write a value to a guest virtual memory (GVM) location in the source VM. The scheduler identifies the HPM location that corresponds to the reserved GVM and allocates it to the target VM by mapping a guest physical memory location of the target VM to the HPM location. |

Method of transmitting signal
A method of transmitting a signal according to the present invention includes: receiving a signal that is encoded with a predetermined code rate and that is modulated by a first modulation method from a base station; creating a signal that is obtained by demodulating the signal that is modulated by the first modulation method using a method corresponding to the first modulation method; creating a signal that is obtained by modulating the demodulated signal using a second modulation method while maintaining the predetermined code rate; and transmitting the signal that is modulated by the second modulation to a mobile station.Therefore, it is possible to reduce the cost of the relay station and simplify the system of the relay station. Further, during the modulation and demodulation, the symbol offset is changed to create various modulated and demodulated signals. |

Delivery of multicast data
A method and apparatus are provided for delivering multicast media in a network in which at least some nodes do not support delivery of multicast packets. A RTSP SETUP request is sent to a streaming server to send multicast packets, encapsulated within unicast wrappers, to a gateway node in the network. The RTSP SETUP request includes details both of the multicast destination address, and of the unicast destination address of the gateway node, requiring an extension to the RTSP protocol as currently defined and enabling the media server to send multicast packets in a unicast tunnel dynamically. |

Dynamic energy saving mechanism for access points
Mobile access points typically run on batteries, and therefore, can operate for a limited amount of time without an external power source. However, because the access point service model requiring the access point to always be available and the access point's limited battery capacity reduces the time that the mobile access point can be used. Functionality can be incorporated in mobile access points to implement power saving mechanisms by altering the service model that requires the access point to always be available. Configuring the access point to enter into a low powered state for a predefined period of time can conserve mobile access point power and prolong battery life. Functionality for implementing power saving mechanisms can also be incorporated on fixed access points for efficient utilization of computing resources. |
