Encapsulating an SCTP packet in a UDP packet

A method for enabling a Stream Control Transmission Protocol (SCTP) packet to be encapsulated in a User Datagram Protocol (UDP) packet, for transport from a source network node to a destination network node, the method being performed by the source network node, the method comprising the steps of:

• obtaining a source number based on an identifier of the source network node;
• obtaining a destination number based on an identifier of the destination network node;
• generating an SCTP packet, which comprises setting a source port of the SCTP packet to a predefined port number and setting a destination port of the SCTP packet to the destination number;
• generating a UDP packet, which comprises setting a source port of the UDP packet to the source number and setting a destination port of the UDP packet to the destination number;
• encapsulating the SCTP packet in the UDP packet;
• and
• sending the UDP packet for transport to the destination network node.

A source network node for enabling a Stream Control Transmission Protocol (SCTP) packet to be encapsulated in a User Datagram Protocol (UDP) packet, for transport from the source network node to a destination network node, the source network node comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the source network node to:
• obtain a source number based on an identifier of the source network node;
• obtain a destination number based on an identifier of the destination network node;
• generate an SCTP packet, which comprises setting a source port of the SCTP packet to a predefined port number and setting a destination port of the SCTP packet to the destination number;
• generate a UDP packet, which comprises setting a source port of the UDP packet to the source number and setting a destination port of the UDP packet to the destination number;
• encapsulate the SCTP packet in the UDP packet;
• and
• send the UDP packet for transport to the destination network node.

A source adapter for enabling a Stream Control Transmission Protocol (SCTP) packet to be encapsulated in a User Datagram Protocol (UDP) packet, for transport from a source network node to a destination network node, the source adapter comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the source adapter to:
• receive a UDP packet encapsulating an SCTP packet;
• set a destination port of the SCTP packet to be a same port number as a source port number of the SCTP packet;
• and
• send the UDP packet for transport to the destination network node.
