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.

1-10. (canceled)
A network node, comprising:
- a first Stream Control Transmission Protocol (SCTP) protocol instance providing redundancy of an SCTP endpoint;
- a peer SCTP protocol instance, wherein the first SCTP protocol instance is connected to the peer SCTP protocol instance via an SCTP connection;
- a further SCTP protocol instance, wherein the first SCTP protocol instance is further connected to the 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;
- wherein for the first SCTP protocol instance, an idle mode of operation is defined, and in the idle mode of operation, SCTP messages are forwarded to the further SCTP protocol instance;
- and
- wherein the network node includes a decision unit for deciding, when the SCTP protocol instance is in the idle mode of operation, according to a message type associated with a received SCTP message, whether or not to actively process the received SCTP message.
A method of controlling a Stream Control Transmission Protocol (SCTP) protocol instance associated with a redundantly implemented SCTP endpoint, comprising the steps of:
- defining for the SCTP protocol instance, an idle mode of operation in which an SCTP message received from a peer SCTP protocol instance is forwarded to a further SCTP protocol instance associated with the SCTP endpoint;
- determining an actual status of the mode of operation of the SCTP protocol instance;
- and
- if the SCTP protocol instance is in the idle mode of operation, deciding according to a message type, whether or not to actively process a SCTP message received from a peer SCTP protocol instance.
