  • Method to control dynamic host configuration protocol pool exhaustion in dynamic network environments
    Patent number: 9866522
    Abstract: The present disclosure discloses a method and a network device for controlling DHCP pool exhaustion in dynamic network environments. Specifically, a network device determines that a client device is assigned an Internet Protocol (IP) address by a DHCP server. The network device detects that the client device is disconnected from a network associated with the IP address, for example, by receiving a de-association message from the client device; determining that a session or an entry corresponding to the client device has timed out; determining that the client device has failed to respond to one or more messages transmitted to the client device; determining that the client device has connected to another network different than said network; etc. In response, the network device then generates a DHCP release message on behalf of the client device, and transmits the DHCP release message to the DHCP server.

  • Adaptive dynamic host configuration protocol assignment with virtual local area network pool
    Patent number: 9438557
    Abstract: The present disclosure discloses a method and network device for adaptive DHCP assignment with VLAN pool. Specifically, a network device can assign a client device to a first Virtual Local Area Network (VLAN). The network device then detects a first DHCP Discover message, transmitted by a client device, corresponding to a first VLAN. Also, the network device determines that no DHCP offer message, responsive to the first DHCP Discover message, is transmitted to the client device. Then, the network device transmits on behalf of the client device a second DHCP Discover message for the second VLAN to a DHCP server, and receives a DHCP Offer message in response to the second DHCP Discover message. The network device then assigns the client device to a second VLAN, and subsequently transmits the DHCP Offer message for the second VLAN to the client device.
