Abstract
Embodiments of the present application provide a method and network apparatus of establishing path, applied in a SDN, the method includes: receiving, by a node, forwarding information from a SDNC; wherein the forwarding information is generated based on a relationship between prefix of IP address and tunnel information; receiving a packet, wherein the packet comprises first prefix information of a first IP address; forwarding the packet according to first tunnel information corresponding to the first prefix information of the first IP address. In the application, the process of route calculation is simplified, and number of forwarding flow entry in internal nodes is reduced.
Claims15
A method of establishing path, where the method is applied in a Software Defined Network (SDN), and the method comprises:
- receiving, by a node, forwarding information from a SDN controller (SDNC);
- wherein the forwarding information is generated based on a relationship between a prefix of an IP address and tunnel information;
- receiving, by the node, a packet, wherein the packet comprises first prefix information of a first IP address;
- forwarding, by the node, the packet according to first tunnel information corresponding to the first prefix information of the first IP address.
A method of establishing path, where the method is applied in a Software Defined Network (SDN), and the method comprises:
- establishing, by a SDN controller (SDNC), relationship between a prefix of an IP address and tunnel information;
- generating, by the SDNC, forwarding information based on the relationship;
- sending, by the SDNC, forwarding information to one or more nodes so that the one or more nodes forward packets according to the forwarding information.
A node, comprising:
- a first receiving unit, configured to receive forwarding information from a Software Defined Network Controller (SDNC);
- wherein the forwarding information is generated based on a relationship between a prefix of an IP address and tunnel information;
- a second receiving unit, configured to receive a packet, wherein the packet comprises first prefix information of a first IP address;
- a forwarding unit, configured to forward the packet according to first tunnel information corresponding to the first prefix information of the first IP address.
A Software Defined Network controller (SDNC), comprising:
- an establishing unit, configured to establish a relationship between a prefix of an IP address and tunnel information;
- a generating unit, configured to generate forwarding information based on the relationship;
- a sending unit, configured to send forwarding information to one or more nodes so that the one or more nodes forward packet according to the forwarding information.
An apparatus comprising:
- a Software Defined Network controller (SDNC) configured to establish a relationship between a prefix of an IP address and tunnel information, to generate forwarding information based on the relationship, and to send forwarding information to one or more nodes so that the one or more nodes forward packet according to the forwarding information.
