Method and system for originating connectivity fault management (CFM) frames on non-CFM aware switches

InactiveUS20070140126A1Effective expansionAvoid a lotError preventionFrequency-division multiplex detailsOperations, administration and managementOperability
A system for originating connectivity fault management (CFM) frames on non-CFM aware switches is disclosed. In the disclosed system, an OAM (Operations Administration and Management) proxy networking device connected to a core Ethernet network operates with one or more CPE (Customer Premises Equipment) devices to which it is communicably connected to support CFM out to the CPE devices without requiring that the CPE devices themselves implement CFM functionality. The OAM proxy networking device generates Connectivity Check (CC) frames, Loopback reply frames, and Linktrace reply frames for MEPs (Maintenance End Points) or MIPs (Maintenance Intermediate Points) contained in communication ports on the CPEs. These CFM frames generated by the OAM proxy networking device are then sent within messages from the OAM proxy networking device to the appropriate CPE. When the CPE device receives a message from the OAM proxy networking device containing one of these CFM frames, it checks the operability of a communication port indicated by the message. If the port is operable, the CPE device extracts the CFM frame from the message and originates it through the OAM proxy networking device into the core Ethernet network. The OAM proxy networking device further operates to process Connectivity Check frames received from the core Ethernet network and addressed to the CPE devices by maintaining an MEP connectivity database. As a result, these received Connectivity Check frames are dropped without forwarding to the CPE devices.

Method and apparatus for registering devices on Internet of things platform

Disclosed is a method for registering devices on an Internet of things platform. The method comprises the following steps: a user terminal sending a broadcast packet in a local area network so as to obtain the devices supporting an agreed protocol in the local area network; the user terminal receiving equipment device sent by the devices supporting the agreed protocol in the local area network, wherein the equipment information comprises physical identification codes; the user terminal sending the physical identification codes to the Internet of things platform; the user terminal receiving equipment accounts and equipment passwords corresponding thereto which are generated according to the physical identification codes and are returned by the Internet of things platform, wherein the equipment accounts and the equipment passwords are used by the devices for registering the Internet of things platform so as to enable the devices to communicate with the Internet of things platform; and the user terminal sending the equipment accounts and the equipment passwords to the corresponding devices. The method provided by the invention provides a foundation for communication between a user end and the devices. Besides, the invention further discloses an apparatus for registering devices on an Internet of things platform.

Super-scalable, continuous flow instant logic™ binary circuitry actively structured by code-generated pass transistor interconnects

A processing space contains an array of operational transistors interconnected by circuit and signal pass transistors that when supplied with selected enable bits will structure a variety of circuits that will carry out any desired information processing. The Babbage/von Neumann Paradigm in which data are provided to circuitry that would operate on those data is reversed by structuring the desired circuits at the site(s) of the data, thereby to eliminate the von Neumann bottleneck and substantially increase the computing power of the device, with the apparatus conducting only non-stop Information Processing on a steady stream of data and code, with no repetitious Instruction and data transfers as in the normal computer being required. A code is defined that will identify the physical locations of every transistor in the processing space, which code will then enable only selected ones of the pass transistors therein so as to structure the circuits needed for any algorithm sought to be executed. The circuits so structured, operating independently of and in parallel with every other circuit so structured, are then restructured after each step into another group of circuits, so that almost no transistor will ever “sit idle,” but all of the processing space can be devoted entirely to information processing, thereby again to increase enormously the computing power of the device. The apparatus is also super-scalable, meaning that an Instant Logic Apparatus built around that processing space could be built to have any size, speed, and level of computer power desired.
