Abstract
Measures for processing data in a packet-switched network. At a first device in the network, a packet transmitted from a second device in the network is received. The received packet comprising an Internet Protocol (IP) address for a third device in the network. On the basis of the IP address for the third device comprised in the received data packet, lookup in an IP routing table of the second device is initiated to obtain a next-hop address for the received packet. The obtained next-hop IP address is determined to be an IP address of a device connected to the first device.
Claims25
A method of processing data in a packet-switched network, the method comprising:
- receiving, at a first device in the network, a packet transmitted from a second device in the network, the received packet comprising an Internet Protocol (IP) address for a third device in the network;
- initiating lookup, on the basis of the IP address for the third device comprised in the received data packet, in an IP routing table of the second device to obtain a next-hop address for the received packet;
- and
- determining the obtained next-hop IP address to be an IP address of a device connected to the first device.
A system for use in processing data in a packet-switched network, the apparatus comprising:
- at least one memory including computer program code;
- at least one processor in communication with the memory, wherein the processor is configured to,
- receive, at a first device in the network, a packet transmitted from a second device in the network, the received packet comprising an Internet Protocol (IP) address for a third device in the network;
- initiate lookup, on the basis of the IP address for the third device comprised in the received data packet, in an IP routing table of the second device to obtain a next-hop address for the received packet;
- and
- determine the obtained next-hop IP address to be an IP address of a device connected to the first device.
A non-transitory computer-readable storage medium having computer readable instructions stored thereon, wherein, when executed by a processor, cause a computing device to perform a method for processing data in a packet-switched network, the method comprising:
- receiving, at a first device in the network, a packet transmitted from a second device in the network, the received packet comprising an Internet Protocol (IP) address for a third device in the network;
- initiating lookup, on the basis of the IP address for the third device comprised in the received data packet, in an IP routing table of the second device to obtain a next-hop address for the received packet;
- and
- determining the obtained next-hop IP address to be an IP address of a device connected to the first device.
