An API including a registration function and a configuration function, is provided to an optical networking apparatus to facilitate registration of configuration specification delimiter pairs by service routines of function blocks of multi-protocol optical networking modules (MPONM), and extraction of configuration specifications for the function blocks from a configuration specification input set using the registered configuration specification delimiter pairs. In one embodiment, the configuration function also receives current configuration of the function blocks, and merges the received current configurations of the function blocks into a configuration specification output set, separating the merged configuration specification using the registered configuration specification delimiters.

Extensible configuration methods for optical networking apparatuses with multiple multi-protocol optical networking modules

A unified API is provided to an optical networking apparatus to facilitate uniform access, control or interaction with its multi-protocol optical networking modules (MPONM) by its applications. Each of the MPONM has a multi-protocol processor with a number of function blocks and physical layer components. Corresponding service routines are provided for the function blocks and the physical layer. Functions of the function block/physical layer service routines are externalized through the same unified API, thereby enabling accesses and interactions with physical layer components of a MPONM to be conducted in the same high level manner as accesses and interactions with function blocks of the multi-protocol processor of the MPONM.

Software methods of an optical networking apparatus with integrated modules having multi-protocol processors and physical layer components

An optical networking module is formed with an integrated module including optical, optical-electrical and protocol processing components, and complementary software. In one embodiment, the integral protocol processing component is a single ASIC and supports multiple protocols. The module is further equipped with support control electronics in support of control functions to manage the optical, optical-electrical as well as the multi-protocol processing component. The integrated module together with the complementary control software present to an optical networking equipment designer/developer a singular component that handles optical to electrical and electrical to optical conversion, as well as data link and physical sub-layer processing for a selected one of a plurality of datacom and telecom protocols, spanning local, regional as well as wide area networks. The integrated module and complementary control software further presents to the optical networking designer/developer a unified software interface for managing-the various components and functions.

Methods and apparatus reduce the computational load for computing r=x mod n, given two numbers x and n, where x is 2t bits long and n is t bits long. Such reduced computational loading in modular reduction schemes is useful for, at least, network communication systems that include modular reduction in cryptography, particularly, public key encryption algorithms such as RSA, El Gamal, Rabin, and Diffie-Hellman.

Method and apparatus of fast modular reduction

In a network apparatus, control logic is provided to preemptively issue pause controls to a sender of network traffic of a link to preemptively regulate a rate the sender may send network traffic of the link. In one embodiment, the pause controls are sent periodically, with each including a pause duration. In one embodiment, at least a selected one of the pause duration and the periodicity of preemptive issuance is determined based at least in part on at least a selected one of a working capacity of storage medium allocated to service the link, a network traffic drain rate of the link, and a fill rate of the input line over which the network traffic of the link is received. In one embodiment, the networking apparatus is an optical networking module with the control logic disposed in a multi-protocol networking processor of the module.

Preemptive network traffic control for regional and wide area networks

An apparatus is equipped with a deciphering round key generator to successively generate in real time at least a first and a second deciphering round key based on a deciphering key, and a deciphering unit coupled to the deciphering round key generator to successively employ the real time successively generated deciphering round keys to incrementally decipher a ciphered text. The deciphering round key generator at least generates the second deciphering round key in real time while the deciphering unit deciphers the ciphered text employing the real time generated first deciphering round key. At a result, deciphering round keys may be generated in a much more efficient manner on an as needed basis.
