Alignment-enabled secondary nodes of a DAMA network monitor the alignment of for-transmission data as it is received, and actively align the data frames into encoded blocks such that the number of blocks occupied by encoded data resulting from an unencoded datastream of a particular length is predictable rather than variable. In some embodiments, the network is an Ethernet passive optical network and the alignment includes aligning a XGMII word having a start control code to a first position in a 72 bit word input to a 66B/66B encoder, thereby encoding a start-of-frame (/S/) code to a first byte of an encoded first Ethernet 66b block.

Encoding for efficient use of an upstream channel in burst mode

Methods for increasing upstream bandwidth utilization in an Ethernet passive optical network (EPON) use in some instances round-down instead of round-up occupancy values reported to an optical line terminal. An optical network unit determines whether the occupancy needs to be round-up or round-down and reports the occupancy in either round-up or round-down report units to the optical network terminal.

Reporting mechanism for efficient upstream bandwidth utilization in a 10G EPON

A method and system is provided for securing communication on an EPON. Particularly different types of encrypted messages, each with a respective short MAC SegTAG, may be sent from the OLT to an ONU and from an ONU to the OLT without need for a full SecTAG with an explicit SCI. Discovery and control messages may be encrypted and a security offset may be less than 30 bytes. A packet header including its MAC address may be encrypted.

Implementing IEEE 802.1AE and 802.1 af security in EPON (1GEPON and 10GEPON) networks

A system and method for power saving in IEEE-style and ITU-T G.-style networks overcomes the limitations of conventional techniques using information from user and network devices for initiating power savings by the user or network device, enabling power savings on links such as optical networks. This innovative technique provides a system and method for communications between user and network devices, facilitating either the user or network device initiating a sleep mode for the user device. The implementation of a sleep mode in a device allows powering down of the device's transmitter and receiver for a specified length of time, during which the transmitter and receiver (also referred to as the physical interface of the device) consume diminished power.

Power saving in IEEE 802-style networks

A method of signaling and detecting end-of-transmission on a data communications link that uses scrambling comprises, by a transmitting node of the network, appending an end of burst delimiter (EBD) binary sequence to burst data and transmitting the burst data and the EBD over the communication link to a headend of the network. In a 10 G EPON using a 64B/66B transmission code, the EBD is exemplarily a 198 bit pattern.

End-of-burst detection for upstream channel of a point-to-multipoint link

A broadband gatewaythat combines a broadband modemand a residential gatewayin a single unit. The single unit features a unique dual bridge, shared module architecture that reduces redundancy in the broadband gatewayat the same time it minimizes interactions between modules in the broadband gateway. This minimized interaction permits the broadband gatewayto operate at peak efficiency and allows for continued development of portions of the broadband gatewaywithout necessarily incurring compliance testing for the broadband portion of the broadband gateway
