20120224503 | DISCOVERY OF CONVENTIONAL DEVICES AND BRIDGES IN HYBRID COMMUNICATION NETWORKS - A hybrid network device can implement functionality for automatically detecting and locating legacy bridges in a communication network. In one embodiment, a first network device of a first class of network devices can determine that a second network device of a second class of network devices is communicatively located adjacent to at least one of a plurality of network interfaces of the first network device based, in part, on detecting that a packet originating from the second network device does not include a predetermined tag. The first network device can determine whether network segments associated with the first network device and a target network device are communicatively coupled via a network bridge device of the second class of network devices based on transmitting probe messages to the second network device and determining whether the target network device detected the probe messages. | 09-06-2012 |
20120230343 | ADDRESSING SCHEME FOR HYBRID COMMUNICATION NETWORKS - A hybrid network device can implement an address management scheme for maintaining consistency between source/destination addresses and corresponding source/destination communication interfaces. In one embodiment, a first network device can select a first network path from a plurality of network paths associated with the communication network for transmitting a packet to a second network device. A source address can be determined from a plurality of addresses associated with a plurality of communication interfaces of the first network device. A destination address can be determined from a plurality of addresses associated with a plurality of communication interfaces of the second network device based, in part, on the selected first network path. The packet including at least the source address and the destination address can be transmitted via the first network path from a source communication interface of the first network device to a destination communication interface of the second network device. | 09-13-2012 |
20120320919 | AUTOMATIC PATH SELECTION FOR HYBRID COMMUNICATION NETWORKS - A hybrid network device can implement functionality for automatic path selection and modification in a hybrid communication network. The hybrid network device can select an initial network interface from a plurality of network interfaces for transmitting a packet stream. In response to determining that the medium utilization of the initial network interface exceeds the medium utilization threshold, the hybrid network device can identify one or more packet streams originating from the initial network interface to shift to corresponding one or more alternate network interfaces. The hybrid network device can attempt to reduce the medium utilization of the initial network interface below the medium utilization threshold while maintaining the medium utilization of the one or more alternate network interfaces below the corresponding medium utilization thresholds. The hybrid network device can shift the one or more packet streams from the initial network interface to the corresponding one or more alternate network interfaces. | 12-20-2012 |
20130114606 | MULTIPLE DELIVERY ROUTE PACKET ORDERING - A hybrid network device can implement functionality to indicate the sequence of packets associated with a common packet stream transmitted via a plurality of packet routes and to manage out-of-order packet arrival. In a hybrid communication network, a first network device can determine sequence identifiers associated with a plurality of packets of a packet stream received from a second network device via a plurality of packet routes between the first network device and the second network device. The first network device can detect out-of-order delivery of one or more of the plurality of received packets based, at least in part, on the sequence identifiers associated with the plurality of packets. Consequently, the first network device can re-order at least a subset of the plurality of packets based on the sequence identifiers associated with the plurality of packets. | 05-09-2013 |
20130136117 | WIRELESS BRIDGING IN A HYBRID COMMUNICATION NETWORK - A hybrid device can be configured to use WLAN communication links for bridging network traffic between any pair of network devices in a hybrid communication network, irrespective of whether the bridged network devices support WLAN communication. The hybrid device receives a first data frame in a first frame format for transmission to a destination device. The hybrid device accesses its hybrid forwarding tables and identifies a transmit interface from which to transmit the first data frame for transmission to the destination device. If the transmit interface is a WLAN interface, WLAN forwarding tables associated with the WLAN transmit interface are accessed to identify a receiving WLAN device to which the first data frame should be transmitted. The WLAN transmit interface converts the first data frame into a second data frame in a WLAN frame format and transmits the second data frame to the receiving WLAN device. | 05-30-2013 |
20140029447 | FORWARDING TABLES FOR HYBRID COMMUNICATION NETWORKS - A hybrid device can apply forwarding tables associated with one or more other hybrid network devices of a hybrid communication network to control the entire transmission route of a frame scheduled for transmission. The hybrid device can use its forwarding table and a forwarding table of a destination hybrid device to determine a source network interface address, a destination network interface address, and a frame transmission route. The destination hybrid device can use forwarding tables associated with one or more hybrid network devices to determine whether to process or drop a received frame, whether the frame was previously received, and/or whether the frame was received on an incorrect network interface. The hybrid device can also use the forwarding tables to ensure that the frame comprises an appropriate link layer address and to select an appropriate transmission route based on analyzing link performance values associated with multiple transmission routes. | 01-30-2014 |
20140169222 | BRIDGING NETWORK DEVICES IN A HYBRID COMMUNICATION NETWORK - A hybrid bridge can implement functionality for selectively populating its bridge tables based on preferred transmission routes to influence other network devices to transmit frames based on the preferred transmission routes. The hybrid bridge determines a preferred transmission route for communicating with each network device in the hybrid communication network. For each of the network devices, it is determined whether the hybrid bridge is part of the preferred transmission route associated with the network device. Depending on whether the hybrid bridge is part of the preferred transmission route to the network device and/or whether a network interface of the hybrid bridge is a transmit or a receive interface on the preferred transmission route, a local bridge table or a remote bridge table of the network interface can be populated with at least the address of a destination network device. | 06-19-2014 |
