Abstract
Official abstract text for this publication.
In one example, a network device includes a virtual network agent, and a network interface to send network packets to the virtual network controller using a default route for a physical network prior to establishing a communication session between a virtual network controller and the virtual network agent, wherein, after establishing the communication session between the virtual network controller device and the virtual network agent, the virtual network agent receives from the virtual network controller a command to install a new route at the network device, wherein the new route specifies encapsulation information to use for encapsulating network packets for sending the network packets to the virtual network controller over an overlay network, and wherein, responsive to detecting a failed link in the physical network, the virtual network agent sends packets to the virtual network controller on an alternate route in the overlay network.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: prior to establishing a communication session between a virtual network controller and a virtual network agent executing on a server device, sending network packets by the server device to the virtual network controller using a default route for a physical network; after establishing the communication session between the virtual network controller device and the virtual network agent, receiving from the virtual network controller…
