Differentiated QoS for Wi-Fi clients connected to a cable/DSL network
First Claim
1. A method for acquiring a reserved Internet Protocol (IP) address to provide differentiated Quality of Service (QoS) to a Wi-Fi access point and devices connected to the Wi-Fi access point comprising the step of:
- inserting a special option into a Dynamic Host Configuration Protocol (DHCP) signaling at the Wi-Fi access point to request an IP address from a reserved range of IP addresses from a DHCP server.

Abstract
The preferred method involves segmenting the routable IP address space of a Cable Modem Termination System (CMTS) to identify clients requiring differentiated QoS by assigning IP addresses from reserved ranges. The IP addresses are assigned to home clients/the Wi-Fi AP and roaming users based on special DHCP options inserted by the Wi-Fi AP DHCP Proxy software on behalf the Wi-Fi AP and home client devices and roaming devices using the Wi-Fi AP. This creates potentially multiple service classes whereby IP addresses from the reserved ranges are included in traffic classifiers that cause packets to map to service flows which provide for differentiated QoS to the Wi-Fi AP owner, home clients and roaming users on the cable access network.

8. A method for providing differentiated Quality of Service (QoS) for devices sharing a Wi-Fi access point (AP) attached to a network comprising the step of:
mapping upstream traffic coming from a home client device with a source IP address from a reserved range of IP addresses to a uniquely provisioned service flow at a cable modem. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for acquiring reserved IP addresses to provide differentiated Quality of Service (QoS) to a Wi-Fi access point and devices connected to the Wi-Fi access point comprising:
-
(a) a cable modem connected to a Cable Modem Termination System (CMTS) which is connected to at least one MSO managed network; and (b) a Wi-Fi access point connected to the cable modem and having a memory containing instructions processed by a processor for inserting a special option into a DHCP signaling at the Wi-Fi access point to request an IP address from a reserved range of IP addresses from a DHCP server. - View Dependent Claims (16, 17, 18)
