The present invention relates to a method and a system for controlling a processing load in a packet data network, wherein a load control information is set in a predetermined field of a message. The load control information is then checked on the routing path of the message and a processing resource of the packet data network is selected in response to the result of checking step. Thereby, load balancing information can be provided at the network to thereby provide an efficient balancing and load sharing function without heavy string comparisons and data base queries.

Message-based conveyance of load control information

The invention relates to a method wherein a transport layer association is established. Thereafter, a handover condition is detected in the first mobile node, which obtains a second address. The second address is updated to a first name server node. A query message is sent to a second name server node for an address of the second mobile node. The second address is indicated to the second mobile node. The first mobile node waits for a response from the second name server node or the second mobile node. Upon receiving a new address for the second mobile node from the second name server node, the first mobile node repeats the indication of the second address of the first mobile node to the second mobile node using the new address as a destination address for the second mobile node.

Method for performing handovers in a communication system

The present invention concerns load balancing for control plane traffic of a network element comprising multiple CPU nodes assigned to a common external IP address in a packet data enabled telecommunication network. IP messages addressed to the network element are received, and received IP messages comprising GTP-C messages are identified. A TEID-C value of a GTP-C message is identified and the GTP-C message is forwarded to a CPU node based on its identified TEID-C value, if its identified TEID-C value does not equal zero.

Load balancer for multiprocessor platforms

The present invention describes a method, system and mirror driver for discarding data frames in mirrored data communication networks. In the method, at least one data structure comprising one or more entries is created and maintained, an entry comprising at least a current sender data frame sequence number. When a data frame is received, a hash code is computed using then sender address and the receiver address of the received data frame, the hash code being an index to the table. The current sender data frame sequence number is checked in the entry indexed by the computed hash code, and if the sequence number of the received frame is smaller than the current sender data frame sequence number in the entry, the data frame is discarded as being a duplicate frame.
