Dynamic segmentation of network traffic through the use of Pre-Shared Keys (PSKs). Each defined network segment uses a different pre-shared key and a message authentication code (MAC)-signing algorithm to sign data packets with segment-specific MACs. As such, only those computer hosts/nodes that are in the network segment (i.e., have been assigned the same pre-shared key for generating and decoding the MAC signed data packets) are capable or reading the segment's network traffic. By implementing segment-specific MAC signed data packets, the present invention allows for confidential data transmission absent the need to encrypt the actual contents/data being transmitted.

In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple WAN backhauls and multiple distinct LAN networks; for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks; and for performing self-healing operations utilizing multiple WAN backhauls serving multiple distinct LAN networks. For example, in one embodiment, a first Local Area Network (LAN) access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network (WAN) backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection is to provide the second LAN access device with WAN connectivity; and a traffic aggregation unit is to form a logically bonded WAN interface over the first WAN backhaul and the second WAN backhaul. In some embodiments an optional traffic de-aggregation unit may be used.

A communication system includes a controller, a plurality of devices, and a communication channel to which the controller and the plurality of devices are connected in a ring, and over which a communication frame including a plurality of packets is transmitted as differential signals. Each device monitors a data transmission amount per unit time, and is configured to determine whether or not the monitored data transmission amount exceeds a threshold value, and insert data into one of the packets in the communication frame when the monitored data transmission amount is equal to or less than the threshold value.

A method for optimizing internet traffic from a plurality of local area networks (LANs) to an internet based server connected to internet includes instructions for analyzing an internet data by a gateway computer located in a first LAN of the plurality of LANs to determine a data that is latency sensitive and a data that is not latency sensitive; instructions for sending network steering data, by the gateway computer, to a Central Processing Matrix (CPM); instructions for sending data, by a plurality of customer premises equipment (CPE) located in a second plurality of LANs in the plurality of LANs to the CPM through a listener/reporter located outside of the plurality of LANs; instructions for receiving the network steering data by the listener/reporter from the CPM; and instructions for routing the data that is latency sensitive outside of the second plurality of LANs to the internet based server.

In a relay device, a control unit detects simultaneous transmission of a plurality of data through a first communication bus. When the number of times of detection of the simultaneous transmission within a predetermined time by the control unit is less than the predetermined number of times, a CAN communication unit starts transmission of data through the first communication bus. When the number of times of detection of the simultaneous transmission within the predetermined time by the control unit is equal to or greater than the predetermined number of times, an Ethernet communication unit transmits data through a first communication line.

A switch receiving Ethernet packets is disclosed, including TCP packets and/or non-TCP packets. The Ethernet packets are forwarded to at least two ports by forwarding each TCP Present application relates to a switch receiving Ethernet packets, including TCP packets and/or non-TCP packets, and forwarding the Ethernet packets to at least two ports by forwarding each of the TCP packets to any one of the at least two ports and forwarding each stream of non-TCP packets to one corresponding port of the at least two ports.

A web handling system is described, including a plurality of web handling controllers and a web handling process logic controller networked to form a ring network. A processor of the web handling process logic controller being configured to determine whether a fault exists within the ring network, and responsive to determining that a fault exists within the ring network, to generate and send signals throughout the ring network to switch the configuration of the ring network to at least one linear network.

[Problem] Provided are a network system and a network bandwidth control management method capable of preventing packets that need to preferentially flow from being discarded at a time of high load.

[Solution] A network system 100 includes an external SW 20 that is provided between a virtualization platform and an external NW 20 and configured to control a bandwidth amount of packets flowing into an OVS 5, and an NW control management device 10 that is configured to modify a configuration of bandwidth control and priority control of the external SW 20 in response to addition or deletion of a service of the virtualization platform based on information acquired from compute nodes 1 to 3, a network node 6, and a controller node 7.

A network and method for connecting devices on a Local Area Network (“LAN”) to the Internet via a Network Address Translation (“NAT”) enabled gateway and server. The gateway includes an Internet address for enabling the gateway to be addressed by the server and the LAN. A plurality of ports on the gateway enables the gateway to receive and transmit data to and from the server and the LAN. A processor divides the ports on the gateway into at least a first range and a second range of port numbers. Classified traffic identified as suitable for a higher level of QoS is assigned to the first range of port numbers, and classified traffic identified as suitable for a lower level of QoS is assigned to the second range. The gateway provides devices on the LAN with a level of QoS depending upon the port numbers to which they are assigned.

A method and system for optimizing internet traffic from a Local Area Network (LAN) to an internet based server utilizes a specific gamer private network (GPN) for the classified latency sensitive internet data. The method includes the steps of creating a gateway computer or a master-slaver computer (device) system within a local area network (LAN), and making this gateway computer control the internet data from any device within the LAN to an outside internet based server. The gateway computer sorts the internet data into various categories, including latency sensitive, bandwidth sensitive and exclusion that is neither latency sensitive nor bandwidth sensitive. Based on these classification results, the internet data within various categories are sent out via the respective routes, so as to achieve a smooth and efficient internet data transmission.
