Initiating peer-to-peer tunnels

摘要

Initiating peer-to-peer tunnels between clients in a mobility domain. Client traffic in a mobility domain normally passes from the initiating client to an access node, and from the access node through a tunnel to a controller, and then through another tunnel from the controller to the destination access node, and the destination client. When initiated by the controller, the access nodes establish a peer-to-peer tunnel for suitable client traffic, bypassing the “slow” tunnels through the controller with a “fast” peer-to-peer tunnel. Traffic through this “fast” tunnel may be initiated once the tunnel is established, or traffic for the “fast” tunnel may be queued up until traffic has completed passing through the “slow” tunnel.

主权项

1. A non-transitory Computer Readable Medium (CRM) comprising instructions which, when executed by one or more hardware processors, causes the one or more hardware processors to:
forward, at a first network device on a first communication path between a first network node and a second network node, a data traffic from (i) a first client communicatively coupled with the first network node toward (ii) a second client communicatively coupled with the second network node; determine, at the first network device, whether the data traffic is eligible for peer-to-peer forwarding between the first network node and the second network node; in response to a determination that the data traffic is eligible for peer-to-peer forwarding, instruct at least one of the first network node and the second network node to establish a second communication path that does not include the first network device, for transmitting the data traffic between the first network node and the second network node; and in response to a determination that the data traffic is not eligible for peer-to-peer forwarding, continue to forward the network traffic through the first communication path.
