Abstract: A method for matching character strings to a reference character string, is disclosed. One or more processors receive a plurality of character strings. The one or more processors match each of the plurality of character strings to a main reference character string and registers a match to positions on the main reference character string that satisfy a pre-set match criteria. The one or more processors match each of the plurality of character strings to an alternate reference character string and registers a match to positions on the alternate reference character string that satisfy the pre-set match criteria. The alternate reference character string is derived from the main character string. The one or more processors identifies a match for each of the plurality of character strings that match to either a position on the main reference character string or the alternate reference character string.

Abstract: An IP address assignment method including assigning a chassis serial number to a node during manufacture, generating an array of unique IP addresses composed using the chassis serial number, and assigning a unique IP address from the array to each interface associated with the node.

Abstract: A method and system for transporting SONET signals over an optical telecommunications network, the method including generating a ComBus signal, including payload data, J1/C1 and synchronous payload envelope (SPE), per SONET path, Smart extracting of data from the ComBus signal (J1 detection and N/P detection), gathering the payload data and J1 into short packets, adding a packet header to each short packet, transporting the short packets to a destination, and generating C1 and SPE at the destination so as to reconstruct the SONET signals out of the ComBus signal.

Abstract: A method and system for protecting packets which include services, transported over an optical communication network, against traffic loss of more than 50 milliseconds, the method including: selecting a sub-network of the network; defining a protection scheme in the sub-network; utilizing a standard protocol for failure detection and identification and protection; defining connections between an A side and a Z side in the network, passing through at least one selected network element in said sub-network; automatically adding entries in switching tables of said selected network elements for a working state of said sub-network connections; and adding pre-defined entries in said switching tables for a protection state for each network element in the sub-network.

Abstract: A method for data transmission over an optical network, the method including collecting a plurality of services data to be transmitted in at least one service collection unit, processing the services in their original protocols into packets, and converting the services into optical signals on an optical fiber for transmission into a metro network; and sorting the services from a plurality of packets according to service type in an aggregator, coupled for optical communication to the service collection units, and combining like services for transmission over a compatible transport network.

Abstract: A method for packet processing for data transmission over an optical fiber, the method including the steps of segmenting an incoming bit stream, adding a tag to a header of each segment, each tag including data identifying a route between a source and a destination end-point of the bit stream, encapsulating the tagged segment into a Point-to-Point Protocol (PPP) packet, and mapping the encapsulated packet into a transmission frame (SONET/SDH or other) for transmission over an optical fiber.
