Systems and methods for end point data communications anonymization for a communications hub
A method for end point data communications anonymization for a local communications hub is provided. The method commences with receiving a first request addressed to a server from a computing device. The method further includes selecting a first remote communications hub from a plurality of remote communications hubs. The method continues with modifying the first request to generate a first modified request and sending the first modified request to the first remote communications hub. The first remote communications hub modifies the first modified request to produce a second modified request and forwards the second modified request to the server. The method further includes receiving a first response to the second modified request from the server, modifying the received first response to produce a first modified response, modifying the first modified response to produce a second modified response, and providing the second modified response to the computing device.
MoCA entry device
An entry device includes an entry port, a filter connected to the entry port, a plurality of first output ports, and a plurality of second output ports. A first path extends from the entry port, through the filter, to the first output ports. The first path is configured to pass cable television (CATV) signals therethrough and to prevent at least a portion of multimedia over coax alliance (MoCA) signals from passing therethrough. A second path extends from the entry port, through the filter, to the second output ports. The second path is configured to prevent at least a portion of the CATV signals and at least a portion of the MoCA signals from passing therethrough. A third path extends from the first output ports, through the filter, to the second output ports. The third path is configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough.
Downstream modem channel analysis and allocation system and method
A system and method for identifying a viable channel within an allocated downstream spectrum and establishing communication via a modem thereon. The disclosed technology provides for the broadband analysis of some or all of the available downstream spectrum to obtain a mapping of available channels and directing the modem to establish downstream communication upon at least one of these channels. The system includes an interface via which a user can specify parameters governing the analysis of the available downstream spectrum and the identification of a viable downstream channel.
Data communication in a MoCA access network
A modem configured to operate in a Multimedia over Coax Alliance, MoCA, access network is provided. The modem comprises a combiner having a coaxial interface for connection to a coaxial cable network and at least two frequency-separated southbound interfaces, SBIs; at least two MoCA chips, wherein each MoCA chip is configured to operate a MoCA access link and comprises a MoCA northbound interface, NBI, connected to one each of said SBIs of the combiner, and a data SBI; a link aggregation switch having at least two switchports connected to one each of the data SBIs, and a port to a data communication interface for connection to a client device for communication at a client data rate; wherein the MoCA chips are configured to operate separate MoCA access links at different MoCA access frequency bands over the coaxial cable network.
Software Upgrade in a Home Network Using Lower Layer Messaging
Principles, apparatuses, systems, circuits, methods, and computer program products for performing a software upgrade in a MoCA network includes receiving an image of a software upgrade at a server and sending the image in the MoCA network using an L2ME message channel to a client that is enabled to receive the image and store the image in a client memory. The image may be broken up into packets, and a sequence number may be assigned to each packet to assist the client in assembling them. CRC information may also be appended to the packets to enable the client to verify their contents.
METHOD FOR IMPLEMENTING AN INDUSTRY INTERNET FIELD BROADBAND BUS
The invention relates to a method for implementing an industry internet field broadband bus, and in the method according to the invention, a bus controller and respective bus terminals transmit data in their respective time slices to thereby ensure timely and temporally determinist data transmission. Thus the embodiments of the invention implement a high-performance, highly reliable, and highly real-time method for implementing an industry internet field broadband bus. Moreover a transmission medium of the two-wire data transmission network can be a twisted pair or a shielded twisted pair so that the method according to the embodiment of the invention can be applicable to a traditional industry control facility using a bus, and thus can be highly universally applicable.
METHOD FOR IMPLEMENTING A REAL-TIME INDUSTRIAL INTERNET FIELD BROADBAND BUS
The invention discloses a method for implementing a real-time industrial internet field broadband bus, the method including: determining, by a bus controller, the number of bus terminals connected therewith; and allocating, by the bus controller, time slices for the bus terminals according to the number of bus terminals, and transmitting, by the bus controller, the time slices to the bus terminals so that the bus terminals operate in the allocated time slices. Moreover data are transmitted in the bus system by removing Ethernet/IP message header information to thereby reduce the length of the message, and shorten a transmission delay and a bus scan periodicity so as to improve the real-time characteristic of the bus system.
METHOD FOR DEEP DATA INSPECTION OVER AN INDUSTRIAL INTERNET FIELD BROADBAND BUS
The invention discloses a method for deep data inspection over an industrial internet field broadband bus, the method including: obtaining, by a first node, a message to be transmitted; judging, by the first node, whether a bus device address in the message to be transmitted lies in a preset range of bus device addresses; and if the bus device address lies in the preset range of bus device addresses, then transmitting, by the first node, the message to be transmitted to a processor of the first node. The first node only forwards the message to be transmitted, lying in the preset range of bus device addresses to thereby improve the security of transmitting the message.
METHOD FOR MANAGING CONFIGURATION OF INDUSTRIAL INTERNET FIELD BROADBAND BUS
The invention relates to a method for managing configuration of an industrial internet field broadband bus, the method being applicable to a two-wire data transfer network in which a bus controller and respective bus terminals are synchronized in clock, and the bus controller allocates time slices for the respective bus terminals and the bus controller, so that the bus controller firstly acquires the configuration information, and determines the bus terminal corresponding to the configuration information, and then the bus controller transmits the configuration information to the bus terminal in the time slice occupied by the bus controller, when the bus controller need transmit configuration information to the respective bus terminals, to thereby make the bus terminal perform corresponding configuration operations according to the configuration information.
INDUSTRY INTERNET FIELD BROADBAND BUS ARCHITECTURE SYSTEM
The invention relates to an industry internet field broadband bus architecture system based on the two-wire data transmission network widely used in the traditional industry control system, so that the system can provide high-performance Ethernet communication without modifying original wiring and topologies, thus providing a high-performance, highly reliable, highly real-time, and highly secured solution to switching an industry control system field layer network from a traditional field bus to an industry Ethernet bus.
