Abstract: A method may include identifying an address within a packet of a traffic flow associated with a network device. The method may also include comparing the address within the packet with a stored address, the stored address associated with a route for an alternative traffic path, where the alternative traffic path may be different from a default route of traffic passing through the network device. The method may additionally include, based on the address within the packet matching the stored address, routing the packet along the alternative traffic path instead of the default route of traffic.

Abstract: A method of routing network traffic may include routing traffic from a local network device, through a remote network location, to a third party network resource along a first path. The method may also include determining a first ranking for the first path, and determining a second ranking for a second path from the local network device to the third party network resource along a second path, the second path excluding the remote network location. The method may additionally include, based on the second ranking exceeding the first ranking by a threshold amount, rerouting the traffic along the second path.

Abstract: A method for establishing a communication sessions based on a Network Address Translation (NAT) device is provided. The method comprises configuring the NAT device with policy to control the creation of NAT translation entries to support communications between devices residing behind the NAT device, and devices residing outside the NAT device; wherein said policy allows the NAT device to establish multiple communications sessions, each with a dynamic NAT traversal behavior; and configuring the NAT device to maintain a control plane session with an orchestrator device whereby the NAT device learns parameters required to establish a translation entry for each communications session.

Abstract: A method may include receiving an instruction to route the data to a destination. The method may additionally include inspecting the data to identify metadata associated with the data. The method may further include identifying, based on the metadata, a first routing path and a second routing path that both lead to the destination. The first routing path may include a first communication link, and the second routing path may include a second communication link. The method may also include identifying the first routing path based on a configuration preference of the routing policy. The method may additionally include transmitting the data along the first routing path via the first communication link.

Abstract: A method may include identifying, based on metadata, a first routing path that leads to the destination and a second routing path that leads to the destination. The method may further include identifying, based on the metadata, a configuration preference for the data to be routed along the first routing path. The configuration preference may indicate a first priority for the first routing path and a second priority for the second routing path. The method may also include selecting the first routing path based on the first priority being higher than the second priority. The method may additionally include transmitting the data along the first routing path via the first communication link.
