摘要:
A traffic control device (50) for a Quality of Service-aware packet-based network (10) comprises detection means (52) for detecting packet flows in a packet stream (46) by preferably repeatedly performing a data packet inspection on the packet stream (46), the data packet inspection being neither based on signaling information nor on application awareness, determining means (54) for determining a flow parameter, in particular a flow rate, of at least one of the detected packet flows, assignment means (56) for generating assignment information assigning a resource of the packet-based network (10) to the at least one detected packet flow in dependence of the detected flow parameter, and sending means (58) for sending the assignment information to a resource control device (44) for causing the resource control device (44) to allocate the assigned resource. In such a way, reliable and cost-efficient quality of service management in a packet-based network (10) is facilitated.

The invention concerns a method for distribution of service requests (1) to a plurality of servers (2). The method comprises receiving (3), in particular by a front end distributor (14) a service request (1), retrieving out of the service request (1) data relevant for selecting out of the one or more servers (2) a server (2), where a state of the service is already local, selecting the server (2) based on the data retrieved out of the service request (1) and sending (10) the service request (1) to the selected server (2). The invention concerns further a front end distributor (14) used for distribution of service requests (1) and a system (15) comprising a plurality of servers (2) and a front end distributor (14) for processing service requests (1).

The invention concerns a first server (100) comprising a first computing resource (101), a processor (102) adapted to determine a load indicator, in particular an average load, of a distributed computing system depending on information about the load of the first computing resource (101), in particular load statistic data, and information about the load of at least a second computing resource (121), and adapted to detect when the load indicator exceeds a predetermined first threshold, a sender (103) adapted to send a request for information about the load of the second computing resource (121) to a second server (120) comprising the second computing resource (121), a receiver (104) adapted to receive the information about the load of the second computing resource (121), in particular load statistic data, in a response to the request, wherein the sender (103) is adapted to send a request for activation of a new computing resource upon detecting that the load indicator exceeds the first threshold. The invention concerns a system of server (100) and a respective method as well.

Embodiments can provide an apparatus, a method and/or a computer program for routing data packets in a radio access network. The apparatus 10 comprises means for receiving 12 a data packet 804 from a source network node, the data packet comprises a data packet header and a data packet payload. The apparatus 10 further comprises means for inspecting 14 the data packet. The means for inspecting 14 is operative to perform a first packet inspection on the data packet header to determine information on a source or a destination of the data packet from the data packet header, and the means for inspecting 14 is operative to perform a second packet inspection on the data packet payload based on the information on the source or the destination of the data packet to determine information on an identification of the destination of the data packet. The apparatus 10 further comprises means for determining 16 information on a subsequent network node based on the information on the identification of the destination of the data packet.

The invention concerns a method of transmitting a piece of information, as well as a sender (1) and a receiver (2) to execute this method. The piece of information is to be transmitted from the sender (1) to the receiver (2) through a communication network (100) comprising N at least partly disjoint transmission paths (P1, P2, P3), wherein N is an integer with N > 2. Encoded information is generated by adding redundancy information to the piece of information. The encoded information is split into N subsets of encoded information in a way that the piece of information can only be decoded from a combination of M subsets of the N subsets, wherein M is an integer with 1 N. Each of the N subsets of encoded information is sent via a different path of the N at least partly disjoint transmission paths (P1, P2, P3) from the sender (1) to the receiver (2). The receiver (2) receives M subsets of the N subsets of encoded information. The piece of information is decoded from a combination of the received M subsets of encoded information.
摘要:
A communications subsystem (20) comprises a plurality of interfaces (20.1, 20.2, 20.3), a routing data repository (29) for storing path information associating addresses to the interfaces, a packet forwarding module (25) adapted to detect a destination address of a received data packet and to switch the data packet between the interfaces as a function of the stored path information, and a routing update module (25) adapted to detect a source address (10.1) in a data packet received through a first interface (20.2) of the communications subsystem, retrieve path information relating to the source address from the routing data repository, determine that the retrieved path information associates first source address to a second interface (20.1) of the communications subsystem, and store path information in the routing data repository, wherein the path information associates the source address with the first interface instead of or in addition to the second interface.
摘要:
It is proposed a method to operate a radio access network. A first user processing entity (4) determines first target uplink PRBs (6), physical resource blocks, based on an uplink state (8) for a first UE, user equipment. A second user processing entity (14) determines second target uplink PRBs (16) based on an uplink state (18) for a second UE. A cell processing entity (20) determines first effective uplink PRBs (22) for an uplink transmission of the first UE and second effective uplink PRBs (24) for an uplink transmission of the second UE based on the first and second target uplink PRBs (6, 16).
