The one or more processors are configured to: obtain network traffic comprising first network traffic and second network traffic, wherein the second network traffic originates from one or more user equipment devices (UEs); apply the URSP to the network traffic; and in response to applying the URSP, forward protocol data units (PDUs) of the network traffic to either a first tunnel to a first network slice or a second tunnel to a second network slice. The first tunnel and the second tunnel are established from the device to the first network slice and the second network slice over communication paths that include at least a wireless communication link from the device to a radio access network (RAN). ## Claims ### Claim 1 A device comprising: a memory to store a User Equipment Route Selection Policy (URSP); and one or more processors configured to: obtain network traffic comprising first network traffic and second network traffic, and wherein the second network traffic originates from one or more remote user equipment devices (UEs); apply the URSP to the network traffic; and in response to applying the URSP, forward protocol data units (PDUs) of the network traffic to either a first tunnel to a first network slice or a second tunnel to a second network slice, wherein when applying the URSP to the network traffic, the one or more processors are configured to: obtain one of a Media Access Control (MAC) address, which is assigned to a physical port via which the second network traffic arrives, or a token, which is transmitted by an application running on the remote UEs; use the MAC address or the token to look up, in a table, a traffic descriptor; and apply the URSP to the traffic descriptor to identify the first network slice or the second network slice; and wherein the first tunnel and the second tunnel are established from the device to the first network slice and the second network slice over a wireless communication link from the device to a radio access network (RAN). ### Claim 2 (depends on 1) The device of claim 1, wherein the first network slice includes a default network slice and the second network slice includes an ultra-high performance network slice. ### Claim 3 (depends on 1) The device of claim 1, wherein the first network traffic comprises one or more of: administration network traffic; Internet Multimedia Subsystem (IMS) traffic, or Internet traffic. ### Claim 4 (depends on 1) The device of claim 1, wherein the second network traffic comprises one or more of: gaming traffic; Internet traffic; or enterprise customer traffic. ### Claim 5 (depends on 1) The device of claim 1, wherein the device comprises a modem, and wherein the processor is further configured to: receive the second network traffic from a router device external to the device. ### Claim 6 (depends on 5) The device of claim 5, wherein when the processor receives the second network traffic from the router device, the processor is configured to: receive the second network traffic over Ethernet frames. ### Claim 7 (depends on 6) The device of claim 6, wherein the Ethernet frames include information for identifying traffic descriptors (TDs) of rules in the URSP. ### Claim 8 (depends on 5) The device of claim 5, wherein the router device is configured to: receive the second network traffic from the remote UEs over a wireless connection or a cable. ### Claim 9 (depends on 1) The device of claim 1, wherein network addresses of the first network slice and the second network slice include Internet Protocol version 4 (IPv4) addresses. ### Claim 10 A method comprising: obtaining network traffic comprising first network traffic and second network traffic, and wherein the second network traffic originates from one or more remote user equipment devices (UEs); applying a User Equipment Route Selection Policy (URSP) to the network traffic; and in response to applying the URSP, forwarding protocol data units (PDUs) of the network traffic to either a first tunnel to a first network slice or a second tunnel to a second network slice, wherein applying the URSP to the network traffic comprises: obtaining one of a Media Access Control (MAC) address, which is assigned to a physical port via which the second network traffic arrives, or a token, which is transmitted by an application running on the remote UEs; using the MAC address or the token to look up, in a table, a traffic descriptor; and applying the URSP to the traffic descriptor to identify the first network slice or the second network slice; and wherein the first tunnel and the second tunnel are established from a device to the first network slice and the second network slice over communication paths that include at least a wireless communication link from the device to a radio access network (RAN). ### Claim 11 (depends on 10) The method of claim 10, wherein the first network slice includes a default network slice and the second network slice includes an ultra-high performance network slice. ### Claim 12 (depends on 10) The method of claim 10, wherein the first network traffic comprises one or more of: administration network traffic; Internet Multimedia Subsystem (IMS) traffic, or Internet traffic. ### Claim 13 (depends on 10) The method of claim 10, wherein the second network traffic comprises one or more of: gaming traffic; Internet traffic; or enterprise customer traffic. ### Claim 14 (depends on 10) The method of claim 10, further comprising: receiving the second network traffic from a router device external to the device, wherein the device comprises a modem. ### Claim 15 (depends on 14) The method of claim 14, wherein when receiving the second network traffic from the router device comprises: receiving the second network traffic over Ethernet frames. ### Claim 16 (depends on 14) The method of claim 14, wherein the Ethernet frames include information for identifying traffic descriptors (TDs) of rules in the URSP. ### Claim 17 (depends on 16) The method of claim 16, wherein the router device is configured to: receive the second network traffic from the remote UEs over a wireless connection or a cable. ### Claim 18 (depends on 10) The method of claim 10, wherein network addresses of the first network slice and the second network slice include Internet Protocol version 4 (IPv4) addresses. ### Claim 19 A system comprising: a router device having a port;
