Abstract: Systems and methods for Ethernet forwarding based on inferring topology in a G.8032 ring via control frames, implemented in a network element, include monitoring received control frames; determining which line port on the network element in the G.8032 ring is active based on the received control frames such that the topology of the G.8032 ring is inferred based on the received control frames; and forwarding data frames on the determined line port. The systems and methods can further include, subsequent to a fault and associated G.8032 protection which modifies ring blocks in the G.8032 ring, determining a change in the topology based on the received control frames; and updating the forwarding of the data frames based on the change.

Abstract: A method for initializing and operating a flash memory file system and a computer-readable medium storing a program adapted to perform the method are disclosed. The method includes programming the flash memory file system in order to conceptually divide logical blocks into logical groups, and storing erasure data for one of the logical groups in a first region of a meta block. The method also includes loading erasure data for one logical group into an external memory device and mapping the logical blocks of the current logical group to the physical blocks in accordance with the erasure data loaded into the external memory device. The method also includes storing data of a data file in a data block of a flash memory device in accordance with the mapping of the logical blocks to the physical blocks.

Abstract: Methods and apparatus are provided for bandwidth management within Automatically Switched Optical Networks. An Optical Connection Controller (OCC) provides threshold based load balancing using an upper and a lower threshold for each port of a network element, and once port usage exceeds the upper threshold no more connections are allowed through the port until the port usage falls below the lower threshold. The OCC also minimizes fragmentation of a port so as to reduce the probability of call rejection as a result of fragmentation. The OCC also maintains a database of shortest paths between a network element and each destination, so that connections can be re-established quickly through alternate paths in the event of failure of a link or node. The OCC also provides the entire network with notification of a fault, thereby enhancing CR-LDP fault notification messaging.
