Abstract
In one embodiment, a method for automatically creating a network route using a discovered IP address includes a first network device receiving a plurality of packets over an X2-C. The method further includes determining a packet type of one or more packets of the received plurality of packets. The method further includes discovering one or more IP addresses of a second RBS using information of the one or more packets, wherein the information used for discovering the one or more IP addresses is determined based on the determined packet type of the one or more packet). The method further includes creating a network route between a first RBS and the second RBS for each of the one or more discovered IP addresses.
Claims24
A method in a first network device that is communicatively coupled to a second network device in a network, the first network device communicatively coupled to a first radio base station (RBS), the second network device communicatively coupled to a second RBS, the method comprising:
- receiving a plurality of packets, wherein each packet of the plurality of packets is received over an X2-C interface, wherein each of the plurality of packets contains an Internet Protocol (IP) header, a stream control transmission protocol (SCTP) header, and one or more SCTP chunks;
- determining a packet type of one or more packets of the received plurality of packets;
- discovering one or more IP addresses of the second RBS using information of the one or more packets of the received plurality of packets, wherein the information used for discovering the one or more IP addresses is determined based on the determined packet type of the one or more packets;
- and
- creating a network route between the first RBS and the second RBS for each of the one or more discovered IP addresses.
A first network device that is communicatively coupled to a second network device in a network, the first network device communicatively coupled to a first radio base station (RBS), the second network device communicatively coupled to a second RBS, the first network device comprising:
- a network interface configured to receive a plurality of packets, wherein each packet of the plurality of packets is received over an X2-C interface, wherein each of the plurality of packets contains an Internet Protocol (IP) header, a stream control transmission protocol (SCTP) header, and one or more SCTP chunks;
- and
- an IP address discovery module coupled to the network interface, configured to:
- determine a packet type of one or more packets of the received plurality of packets,
- discover one or more IP addresses of the second RBS using information of the one or more packets of the received plurality of packets, wherein the information used for discovering the one or more IP addresses is determined based on the determined packet type of the one or more packets, and
- create a network route between the first RBS and the second RBS for each of the one or more discovered IP addresses.
