Abstract: Technologies directed to network address translation based on logical channels in a shared private network with a single ingress to an ISP and multiple customer devices are described. One method receives a first public IP address assigned to an endpoint device by an ISP. The method creates a sub-interface on a WAN interface and adds a first rule that translates the first public IP address to a first private IP address assigned to the customer STA and a second rule that translates the first private IP address to the second public IP address. The first customer STA creates a second sub-interface between the customer STA and the endpoint device, adds a third rule that translates the first private IP address to a second private IP address assigned to the first endpoint device, and adds a fourth rule that translates the second private IP address to the first private IP address.

Abstract: Technologies directed to performing switchover across Internet service providers in a last-mile network are described. One method includes receiving, by a first wireless device, a destination address, a first network address of a first network addressing scheme, and a first message. The method further includes determining a first status of at least one of a first NSP or a second NSP. The first NSP uses a second network addressing scheme and the second NSP uses a third network addressing scheme. The method further includes determining a second network address of the third network addressing scheme. The method further includes sending, using the second NSP the second network address and the first message. The method further includes determining a third network address of a fourth network addressing scheme and sending to a fourth wireless device corresponding to the destination address the third network address and the first message.

Abstract: An extension is provided to a Link Aggregation Control Protocol (LACP) that can use the LACP protocol transport and provides Link Aggregation Group (LAG) management while also functioning as a full liveness detection protocol. Bi-directional link detection is supported and timers are configurable to any number. The extension can be backwards compatible with standard LACP and can use a subtype that is specified as unused. The extension can start up using standard LACP packet rates and include additional information in the unused subtype. If a LACP speaker does not support the extension, then the protocol conforms to standard LACP. A state machine of the extension is used if it detects conforming information from a peer speaker. The state machine can allow faster detection should a link error occur.
