Method and system for link aggregation
View Patent ↗Method and system for a first network device and a second network device is provided. The first network device and the second network device communicate with each other via a plurality of network links. A network packet field for applying a hashing technique for selecting one of the network links to transmit the network packet is negotiated between the first network device and the second network device. The hashing technique is identified for selecting the selected network link. The first network device and the second network device, prior to applying the hashing technique exchange hashing parameters.
1. A machine-implemented method for selecting a communication link from among a plurality of communication links, the method comprising:
negotiating a network packet field for applying a hashing technique for selecting one of the plurality of links to transmit a network packet;
determining the hashing technique applied on the network packet field for selecting the one link of the plurality of links; and
exchanging the network packet containing a hashing parameter packet field encoded in the network packet field; and
upon receiving the network packet applying the hashing technique to the hashing parameter in order to select a communication link from among a plurality of communication links for communicating between a first network device and a second network device.
2. The method of claim 1 , wherein the network packet is an Ethernet packet.
3. The method of claim 1 , wherein the plurality of network links are Ethernet links.
4. The method of claim 1 , wherein the first network device is a computing device having a first adapter that negotiates the network packet field, determines the hashing technique, and transmits the network packet the communication link via a second adapter that receives and processes the network packet for a second network device.
5. The method of claim 1 , wherein a switch receives the network packet via the communication link and forwards the network packet to the second network device.
6. A system, comprising:
a first network device and a second network device;
wherein the first network device and the second network device communicate with each other via a plurality of network links;
wherein the first network device and the second network device are configured to:
negotiate a network packet field for applying a hashing technique for selecting one link of the plurality of network links to transmit the network packet;
determine the hashing technique applied on the network packet field for selecting the one link of the plurality of network links; exchange a network packet containing a hashing parameter packet field encoded in a network packet field; and
upon receiving the network packet applying the hashing technique to the hashing parameter in order to select a communication link from among a plurality of communication links for communicating between a first network device and a second network device.
7. The system of claim 6 , wherein the network packet is an Ethernet packet.
8. The system of claim 6 , wherein the plurality of network links are Ethernet links.
9. The system of claim 6 , wherein the first network device is a computing device having a first adapter that negotiates the network packet field, determines the hashing technique, and transmits the network packet the communication link via a second adapter that receives and processes the network packet for a second network device.
10. The system of claim 6 , wherein a switch receives the network packet via the communication link and forwards the network packet to the second network device.
11. A machine-implemented method for selecting a communication link from among a plurality of communication links, the method comprising:
identifying a network packet field for applying a hashing technique for selecting one of the network links to transmit a network packet; and
determining the hashing technique applied on the network packet field for selecting the one link of the plurality of links;
exchanging the network packet containing a hashing parameter packet field encoded in the network packet field;
upon receiving the network packet applying the hashing technique to the hashing parameter in order to select a communication link from among a plurality of communication links for communicating between a first network device and a second network device.
12. The method of claim 11 , wherein the network packet is an Ethernet packet.
13. The method of claim 11 , wherein the plurality of network links are Ethernet links.
14. The method of claim 11 , wherein the first network device is a computing device having a first adapter that negotiates the network packet field, determines the hashing technique, and transmits the network packet the communication link via a second adapter that receives and processes the network packet for a second network device.
15. The method of claim 11 , wherein a switch receives the network packet via the communication link and forwards the network packet to the second network device.
