Abstract
A system that includes a plurality of nodes to forward a data packet in a network, includes a controller to select at least a node dividing a data path of the data packet into a first path and a second path, from the nodes, based on a condition of the data path, and a node selected by the controller being capable of forwarding the packet to the first path and the second path according to an instruction from the controller. The second path includes a bypass path of the first path.
Claims15
A system including a plurality of nodes to forward a data packet in a network, the system comprising:
- a controller to select at least a node dividing a data path of the data packet into a first path and a second path, from the nodes, based on a condition of the data path;
- and
- a node selected by the controller being capable of forwarding the packet to the first path and the second path according to an instruction from the controller,
- wherein the second path comprises a bypass path of the first path.
A node to forward a data packet in a network, the node comprising:
- a first unit to receive an instruction from a controller which selects at least the node dividing a data path of the data packet into a first path and a second path, from a plurality of nodes, based on a condition of the data path;
- and
- a second unit being capable of forwarding the packet to the first path and the second path according to the instruction,
- wherein the second path comprises a bypass path of the first path.
A controller to control a node forwarding a packet in a network, the controller comprising:
- a first unit to select at least a node dividing a data path of the data packet into a first path and a second path, from a plurality of nodes, based on a condition of the data path;
- and
- a second unit to instruct dividing the data path to the node which is capable of forwarding the packet to a first path and a second path,
- wherein in the second path comprises a bypass path of the first path.
A method to forward a packet, the method comprising:
- receiving an instruction from a controller which selects at least the node dividing a data path of the data packet into a first path and a second path, from a plurality of nodes, based on a condition of the data path;
- and
- forwarding the packet to the first path and the second path according to the instruction,
- wherein the second path comprises a bypass path of the first path.
