Abstract: 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.

Abstract: 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.

Both protocol-supported and protocol-unsupported packets may originate from internal or external layers. The NTA includes means to merge such internally and externally originated packages into an internal receive or an internal transmit path, means to split transmit packets between two paths through two data link layers, and means to direct protocol-unsupported packets for external processing.

Abstract: The present invention discloses devices and methods for identifying, analyzing, and repairing network problems. The present invention can be implemented various types of networks including a packet-switched network and an Ethernet passive optical network (EPON), caused by a variety of reasons, culminating in undesirable packet discard. A method of discard-sniffing (DS) is disclosed for monitoring discarded network traffic. A discard reason register stores discard decisions and indications for discard-designated frames, allowing a network administrator to analyze causes for frames being discarded. The discard-designated frames can be routed to alternate destinations based on their designation. Optionally, a configuration register is available to disable DS capability.

Abstract: A method for managing a connection context database comprises the steps of obtaining connection information, sensing the network load of each connection, and allocating system resources with high priority to active connections and low priority to inactive connections. This results in a dynamic context database which enables a limited number of resources to be best used by the most active connections. The method further comprises aggregating TCP/IP packets from the same connection based on information found in the dynamic context database. The processing time of TCP/IP packets received from a host is accelerated through the use of the dynamic context database for aggregation of two or more packets of the same connection.
