Abstract: A network node including a first Stream Control Transmission Protocol (SCTP) protocol instance providing redundancy of an SCTP endpoint. The first SCTP protocol instance connects to a peer SCTP protocol instance via an SCTP connection. The first SCTP protocol instance also connects to a further SCTP protocol instance providing redundancy of the SCTP endpoint via a consistency protocol for providing state consistency between the first SCTP protocol instance and the further SCTP protocol instance. The first SCTP protocol instance also connects to the further SCTP protocol instance via a connection for forwarding messages addressed to the further SCTP protocol instance to be processed by the first SCTP protocol instance or vice versa.

Abstract: The invention relates to a method and a termination node for bundling multiple messages into a packet having a predetermined maximum size. The total size of messages received from an upper layer is checked if it is large enough to fill the maximum-sized packet. If not, the receipt of further messages is waited for a bundling delay time and if the bundling delay time has expired the messages received during said delay time are bundled into the packet. In order to ensure primarily a maximal bundling efficiency and secondarily a lowest possible delay time for the received messages before they are bundled the bundling delay time is calculated in response to an average arrival rate and an average size of the previously received messages such that the bundling delay time corresponds to an average time to fill the packet of the predetermined maximum size.

Abstract: The invention relates to a network node (NN) comprising a first SCTP protocol instance (PI) providing redundancy of an SCTP endpoint the first SCTP protocol instance (PI) is connectable to a peer SCTP protocol instance via an SCTP connection (C1). Furthermore the first SCTP protocol instance is connectable to a further SCTP protocol instance providing redundancy of the SCTP endpoint via a consistency protocol for providing state consistency between the first SCTP protocol instance and the further SCTP protocol instance and via a connection for forwarding messages addressed to the further protocol instance to be processed by the first protocol instance or vice versa.
