Broadband network gateway (BNG) as dynamic host configuration protocol (DHCP) server
In some implementations, a broadband network gateway (BNG) may receive, from a customer premises equipment, a dynamic host configuration protocol (DHCP) discover request, wherein the BNG is connected to the customer premises equipment and a fixed mobile interworking function (FMIF). The BNG may communicate with, based on the DHCP discover request, the FMIF. The BNG may provide to the customer premises equipment, and based on communicating with the FMIF, a DHCP offer that offers utilization of the BNG as a DHCP server. The BNG may receive from the customer premises equipment, and based on providing the DHCP offer, a DHCP request to request utilization of the BNG as the DHCP server. The BNG may provide to the customer premises equipment, and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server.
1. A method, comprising:
receiving, by a broadband network gateway (BNG), from a customer premises equipment, and based on providing a dynamic host configuration protocol (DHCP) offer that identifies an address, a DHCP request to request utilization of the BNG as a DHCP server and request that the customer premises equipment be assigned the address; and
providing, by the BNG, to the customer premises equipment, and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server and that the customer premises equipment is assigned the address.
2. The method of claim 1 , wherein the customer premises equipment is a fixed network cable residential gateway.
3. The method of claim 1 , wherein the address is an Internet protocol version 4 (IPv4) address.
4. The method of claim 1 , wherein the address is an Internet protocol version 6 (IPv6) address.
5. The method of claim 1 , further comprising:
communicating with a fixed mobile interworking function (FMIF) to allow the FMIF to cause:
a context to be established for the customer premises equipment;
a protocol data unit (PDU) session to be established for the customer premises equipment; and
a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.
6. The method of claim 5 , wherein communicating with the FMIF comprises:
providing, to the FMIF, a login request; and
receiving, from the FMIF and based on providing the login request, a login success response,
wherein receiving the login success response allows the BNG to provide the DHCP offer to the customer premises equipment.
7. The method of claim 1 , further comprising:
receiving, based on providing the DHCP acknowledgment, an address resolution protocol (ARP) request that requests an address of the BNG;
providing, to the customer premises equipment, and based on the ARP request, an ARP response that includes the address of the BNG; and
mapping, based on providing the ARP response, the address of the BNG to a protocol data unit (PDU) session identifier of a PDU session established for the customer premises equipment.
8. The method of claim 7 , further comprising:
enabling data packets to be provided from the customer premises equipment to a data network, via a general packet radio service (GPRS) tunneling protocol (GTP) tunnel, based on mapping the address of the BNG to the PDU session identifier.
9. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a broadband network gateway (BNG), cause the BNG to:
receive, from customer premises equipment and based on providing a dynamic host configuration protocol (DHCP) offer that identifies an address, a DHCP request to request utilization of the BNG as a DHCP server and request that the customer premises equipment be assigned the address; and
provide, to the customer premises equipment and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server that that the customer premises equipment is assigned the address.
10. The non-transitory computer-readable medium of claim 9 , wherein the customer premises equipment is a fixed network cable residential gateway.
11. The non-transitory computer-readable medium of claim 9 , wherein the address is an Internet protocol version 4 (IPv4) address.
12. The non-transitory computer-readable medium of claim 9 , wherein address is an Internet protocol version 6 (IPv6) address.
13. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:
communicate with a fixed mobile interworking function (FMIF) to allow the FMIF to cause at least one of:
a context to be established for the customer premises equipment;
a protocol data unit (PDU) session to be established for the customer premises equipment; or
a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.
14. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:
provide, to a fixed mobile interworking function (FMIF), a login request; and
receive, from the FMIF and based on providing the login request, a login success response,
wherein receiving the login success response allows the BNG to provide the DHCP offer to the customer premises equipment.
15. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:
receive, based on providing the DHCP acknowledgment, an address resolution protocol (ARP) request that requests an address of the BNG;
provide, to the customer premises equipment, and based on the ARP request, an ARP response that includes the address of the BNG; and
map, based on providing the ARP response, the address of the BNG to a protocol data unit (PDU) session identifier of a PDU session established for the customer premises equipment.
16. A broadband network gateway (BNG), comprising:
one or more memories; and
one or more processors to:
receive, from customer premises equipment and based on providing a dynamic host configuration protocol (DHCP) offer that identifies an address, a DHCP request to request utilization of the BNG as a DHCP server and request that the customer premises equipment be assigned the address; and
provide, to the customer premises equipment, and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server and that the customer premises equipment is assigned the address.
17. The BNG of claim 16 , wherein the one or more processors are further to:
communicate with a fixed mobile interworking function (FMIF) to allow the FMIF to cause at least one of:
a context to be established for the customer premises equipment;
a protocol data unit (PDU) session to be established for the customer premises equipment; or
a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.
18. The BNG of claim 16 , wherein the customer premises equipment is a fixed network cable residential gateway.
19. The BNG of claim 16 , wherein the address is an Internet protocol version 4 (IPv4) address.
20. The BNG of claim 16 , wherein the address is an Internet protocol version 6 (IPv6) address.
