摘要： One embodiment of the present invention provides a system that accommodates different clock frequencies in an EPON. The system receives a signal from the OLT at the ONU and derives an OLT clock. The system also maintains a local clock. The system further receives from the OLT an assignment for an upstream transmission window, during which the ONU can transmit an upstream data burst to the OLT based on the local clock. The system adjusts the number of bits of the data burst without affecting the payload data carried in the data burst, thereby allowing the data burst to fit properly within the upstream transmission window and compensating for frequency differences between the local clock and the OLT clock. The system transmits the data burst based on the local clock in the upstream transmission window.

摘要： One embodiment of the present invention provides a system that performs remote network management over an Ethernet connection between a local node and a remote node, wherein the Ethernet connection uses x-bit/y-bit (xB/yB) encoding. During operation, the system accepts a local Ethernet bit stream containing x-bit words at the local node. The system forms a second bit stream which carries network management information. The system then selectively encodes the x-bit words from the local Ethernet bit stream into y-bit words according to the bits from the second bit stream, thereby forming a third bit stream comprising y-bit words, wherein the third bit stream carries both information from the Ethernet bit stream and information from the second bit stream. The system then transmits the third bit stream on a physical medium from the local node to the remote node.

摘要： One embodiment of the present invention provides a system that facilitates transmission control in an Ethernet passive optical network, which includes a central node and at least one remote node, and wherein a remote node implements a data-link layer and a physical layer. During operation, the system starts by receiving, at the physical layer of a remote node, a word which is communicated from the data-link layer of the remote node, wherein the word may be a data word or an idle word. The system then delays the word for a pre-determined amount of time before allowing the word to be transmitted by a transmitter, thereby providing time for turning the transmitter on or off. The system also turns the transmitter on or off based on the content of the received words.

摘要： One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network. During operation, the system receives a request from a remote node for a grant to transmit upstream data from a logical entity associated with the remote node to a central node, wherein the size of the data to be transmitted does not exceed a transmission threshold assigned to that logical entity, and wherein a logical entity may not request more than what is allowed by the corresponding transmission threshold. If the request satisfies a bandwidth allocation policy, the system issues a grant to the remote node to transmit upstream data. In response to the grant, the system receives upstream data from the remote node and transmits data stored in the receiver buffer to the out-going uplink according to a set of SLAs.

摘要： One embodiment provides a media access control (MAC) module facilitating operations of an Ethernet passive optical network (EPON). The MAC module includes a frame formatter configured to generate a MAC control frame. The generated MAC control frame includes at least one of: an organizationally unique identifier (OUI) field, an OUI-specific operation code (opcode) field, and a number of fields associated with the OUI-specific opcode. Transmission of the MAC control frame facilitates realization of an EPON function based on the fields associated with the OUI-specific opcode.

摘要： One embodiment provides a system for decrypting data frames in an Ethernet passive optical network (EPON). During operation, the system maintains a local cipher counter at a local node, and receives from a remote node a data frame which is encrypted based on a remote input block and a session key. The remote input block is constructed based on the remote cipher counter and a remote block counter. The system updates the local cipher counter based on a received field located in a preamble of the data frame, truncates the local cipher counter by discarding a number of least significant bits, and constructs for the received data frame a local input block based on the truncated local cipher counter, the received field, and a local block counter. The system then decrypts the data frame based on the local input block and the session key.

IPC分类号： H04L12/413
摘要： One embodiment of the present invention provides a method for facilitating asymmetric line rates in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system provides a downstream code-group clock, wherein each cycle thereof corresponds to a code group transmitted from the central node to a remote node. The system also provides an upstream code-group clock, wherein each cycle thereof corresponds to a code group received at the central node from a remote node. In addition, the system provides a multi-point control protocol (MPCP) clock, wherein the frequency ratio of the MPCP clock to the downstream code-group clock is different from the frequency ratio of the MPCP clock to the upstream code-group clock, thereby allowing the downstream transmission to be performed at a faster line rate than the upstream transmission line rate.
