Abstract:
A data source on a main local area network (LAN) transmits broadcast messages via bridges to remote stations. A ring buffer in a bridge (14) on the main LAN buffers a selected number of packets received from the data source. When the main bridge (14) on the main LAN receives a "Lost Frame Message" from a remote bridge (16), not on the main LAN, the main bridge (14) backs up to the address of the lost packet in the ring buffers, and retransmits the lost packet and then continues sequential transmission of subsequent packets. If buffer get filled above a pre-set criteria, retransmission is slowed or stopped until buffer is mostly emptied.
Abstract:
A system for interconnecting widely separated local area networks (LANs) (11,12) by means of a wide area network (WAN) (10) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point (13,14) which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge.

Abstract:
Methods and systems are provided for managing an Internet of Things object having a single active Radio Access Technology for communication with a data network via a hub of a local network. The method comprises: receiving, by a service provider server connected to the data network, information indicating a loss of connectivity between the Internet of Things object and the data network via the hub; and establishing, by the service provider server, a relay connection between the Internet of Things object and the data network, connectivity between the Internet of Things object and the data network being restored via the relay connection.
Abstract:
Method and communication web service for providing secure communication service for BACnet devices via Internet, wherein the communication web service CCL acts as hub and switch and is configured to be accessed by BACnet devices via a respective outbound HTTPS connection to a pre-defined URL, and wherein the communication between the communication web service CCL and the BACnet devices is based on BACnet via the "BACnet Cloud Link" (BCL) protocol over the WebSocket protocol.
Abstract:
An apparatus is provided for control of a plurality of forwarding switches using a network controller. The network controller executes a routing configuration application that analyzes interconnections between the forwarding switches to identify a topology of the network, determine label switched paths (LSPs) between the forwarding switches, and transmits the next hop routes to the forwarding switches. The forwarding switches use the next hop routes to route packets through the network according to a multiprotocol label switching (MPLS) protocol. Each LSP includes one or more next hop routes defining a forwarding address associated with one forwarding switch to an adjacent forwarding switch.

Abstract:
The invention relates to the distant monitoring and control of a cluster comprising nodes (315, 335) connected to a communication network of a first type (305). One of these nodes (315), called the relay node, comprises a first and a second network interface conforming to the first and to a second type of communication network, respectively. After having been received via the first network interface, a data packet is encapsulated in a data frame conforming to a protocol of the communication network of the second type. The data frame is then transmitted to a remote computer via the second network interface. The steps of receiving a data packet, of encapsulating a data packet and of transmitting a data frame are implemented in the relay mode.
