Media access control address translation for a fiber to the home system
First Claim
1. In a fiber to the home (FTTH) system including a central office that interfaces a packet data network with a passive optical network (PON), a media access control (MAC) layer address translation system, comprising:
- a home network unit (HNU) coupled to the PON and having an associated base MAC layer address and an associated secondary MAC layer address that identify the HNU within the PON;
a host system coupled in a network to the HNU and having an associated host MAC layer address that identifies the host system within the network; and
a MAC address table stored in a memory device that associates the host MAC layer address with the secondary MAC layer address;
wherein upon receiving an outgoing transmission from the host system that includes the host MAC layer address, the HNU accesses the MAC address table to determine the secondary MAC layer address that is associated with the host MAC layer address and modifies the outgoing transmission to replace the host MAC layer address with the secondary MAC layer address.

Abstract
A media access control (MAC) layer address translation system is included in a fiber to the home (FTTH) system having a central office that interfaces a packet data network with a passive optical network (PON). The (MAC) layer address translation system includes a home network unit (HNU), a host system, and a MAC address table. The HNU is coupled to the PON and has an associated base MAC layer address and an associated secondary MAC layer address that identify the HNU within the PON. The host system is coupled in a network to the HNU and has an associated host MAC layer address that identifies the host system within the network. The MAC address table is stored in a memory device, and associates the host MAC layer address with the secondary MAC layer address. Upon receiving an outgoing transmission from the host system that includes the host MAC layer address, the HNU accesses the MAC address table to determine the secondary MAC layer address that is associated with the host MAC layer address and modifies the outgoing transmission to replace the host MAC layer address with the secondary MAC layer address.

24. In a fiber to the home (FTTH) system including a central office that interfaces a packet data network with a passive optical network (PON), a method for providing a secure connection between a host device in the FTTH system and the packet data network, comprising:
-
providing a home network unit (HNU) coupled in the FTTH between the PON and the host device and having an associated base MAC layer address and an associated secondary MAC layer address that identify the HNU within the PON; transmitting an outgoing data packet from the host device to the HNU that includes a host MAC layer address associated with the host device; accessing a MAC address table to associate the host MAC layer address with the secondary MAC layer address; modifying the outgoing data packet to remove the host MAC layer address and add the secondary MAC layer address; and transmitting the modified outgoing data packet from the HNU to the packet data network via the PON and central office. - View Dependent Claims (25, 26, 27, 28)
