摘要:
The present invention relates to methods and arrangements for arranging a distribution tree in a Peer To Peer P2P streaming system. The system comprises a bootstrapping server (10) that creates an external distribution tree based on received register messages from participating operator external clients (2, 3, 4). The method comprises the following steps: —Configuring an operator controlled node (7) to be a regular node in the created external distribution tree. Configuring the operator controlled node (7) to be a parent node for participating operator internal clients (1, 5, 6).

A system, computer readable medium and method for providing to a user device (20) location information of a data device that provides a specific asset, where the user device (20) is present in a network (32) that includes at least a serving node (36) and an address of the user device (20) is indicative of a gateway node (35) that is different from the serving node (36). The method includes receiving at the serving node (36) a first message from the user device (20), the first message including a request for the specific asset; sending the first message from the serving node (36) to the gateway node (35); receiving at the serving node (36) a second message from the gateway node (35), the second message including a first location of a first data device (44) that provides the specific asset; modifying at the serving node (36) the second message to include an indication about a second location of a second data device (46) that provides the specific asset, where the first location is different from the second location; and sending the modified second message including the second location to the user device (20) for accessing the specific asset.

摘要:
In one aspect, the present invention comprises a method or methods for introducing ad insertion and ad management into operator networks (Core Network or Radio Access Network), thereby improving ad management capabilities and avoiding the need for the operator to share internal network or UE information with third parties. In one or more embodiments, the contemplated method(s) and supporting apparatuses are applicable to scenarios where the network operator and a third-party ad provider have an agreement and where they do not.

A system, computer readable medium and method for splitting a virtual machine that runs on a first physical machine that includes at least a processor and a memory. The method includes receiving instructions for splitting in two or more groups plural processes running on the virtual machine; grouping the plural processes in the two or more groups in the virtual machine; splitting the virtual machine into two or more new virtual machines based on an underlying virtualization engine running on the first physical machine; and maintaining active in each new virtual machine those processes that belong to a corresponding group of the two or more groups.
摘要:
A probing method, arrangement, and system for estimating a condition, such as available bandwidth, of a data path in a communication network including multiple nodes are described. A probe-packet sender node transmits probe packets with a sent inter-packet separation and a time-to-live towards an intermediate node. Control message packets are generated by the intermediate node when the time-to-live expires. The probe-packet sender node receives the control message packets and calculates a received inter-packet separation. An estimate of the data path condition can be generated based on the sent inter-packet separation and the received inter-packet separation.
摘要:
A method of measuring network performance is disclosed. A payload packet is transmitted from a sending node to a receiving node via a communication network. A reference packet is transmitted to the receiving node in connection with sending of the payload packet. Receive information related to the payload packet and to the reference packet is generated, at the receiving node. Send information related to the payload packet and to the reference packet is received, by the receiving node. Network performance is estimated by utilizing the send and receive information.

A system, computer readable medium and method for merging a first virtual machine and a second virtual machine that runs on a same or different physical machine. The method includes a step of receiving instructions for merging processes of the first virtual machine with processes of the second virtual machine; a step of merging the first virtual machine with the second virtual machine onto a first physical machine; a step of merging an operating system of the first virtual machine with an operating system of the second virtual machine onto the first physical machine; and a step of maintaining active in the merged virtual machine each process that was active prior to merging the first and second virtual machines.

The invention relates to a visualization platform (9) arranged to provide at least one virtual operating system instance (9A, . . . , 9N) to at least one remote network (3) over a packet-based communication network (5). The visualization platform is characterized in that it comprises at least one first termination point (4b) of a virtual private network VPN tunnel (10) which enables the establishment of at least one VPN tunnel between said at least one first termination point and at least one second termination point (4a) in said at least one remote network over said packet-based communication network; and in that it is arranged to map said at least one virtual operating system instance to said at least one first termination point of said at least one VPN tunnel. The invention also relates to a method for virtualization and a computer program product.
