Abstract
There is provided a method for network address translation. The method is performed by a gateway. The method comprises acquiring an in-packet Bloom Filter (iBF) representation of a node. The method comprises embedding an indication of the iBF representation in an IP address, thereby enabling translation of the iBF representation of the node to an IP address of the node. There is also presented a gateway configured to perform such a method and a computer program comprising computer program code which, when run on a processing unit of the gateway, causes the processing unit to perform such a method.
Claims17
A method for network address translation between in-packet Bloom Filter, iBF, representations used in a first network and Internet Protocol, IP, addresses used in a second network, the method being performed by a gateway not in the first network, comprising the steps of:
- acquiring an iBF representation of a node within the first network;
- and
- embedding an indication of said iBF representation in an IP address used in the second network for the node, to enable translation of said iBF representation of the node in the first network to the IP address of the node in the second network;
- wherein said indication is determined by:
- mapping said iBF representation to a suffix of said IP address of the node;
- and
- storing said mapping in a look-up table, wherein said indication is defined by said mapping.
A gateway for network address translation between in-packet Bloom Filter, iBF, representations used in a first network and Internet Protocol, IP, addresses used in a second network, the gateway not in the first network comprising a processing unit configured to:
- acquire an iBF representation of a node within the first network;
- and
- embed an indication of said iBF representation in an IP address used in the second network for the node, to enable translation of said iBF representation of the node in the first network to the IP address of the node in the second network;
- wherein said indication is determined by:
- mapping said iBF representation to a suffix of said IP address of the node;
- and
- storing said mapping in a look-up table, wherein said indication is defined by said mapping.
A non-transitory computer readable medium comprising a computer program for network address translation between in-packet Bloom Filter, iBF, representations used in a first network and Internet Protocol (IP) addresses used in a second network, the computer program comprising computer program code which, when run on a processing unit of a gateway not in the first network, causes the processing unit to:
- acquire an iBF representation of a node within the first network;
- and
- embed an indication of said iBF representation in an IP address used in the second network for the node, to enable translation of said iBF representation of the node in the first network to the IP address of the node in the second network;
- wherein said indication is determined by:
- mapping said iBF representation to a suffix of said IP address of the node;
- and
- storing said mapping in a look-up table, wherein said indication is defined by said mapping.
