摘要： A method, apparatus and system for transferring data from an apparatus called multi-protocol gateway in a network seamlessly that operates using a particular protocol, to another device that is either in the same network or outside operating in a totally different protocol is described. Today, to accomplish this requires external units, one per technology. For example, for supporting both WiFi and WiMAX devices today, we would require a WiFi access point, a WiMAX base station and a router. We provide plug-ins that would handle multiple protocols within the same gateway, to cater to devices that operate in those protocols. The apparatus translates between various protocols in the back end making it inexpensive and portable. The unit is scalable, grows with technology, and acts as a gateway to a local network. The device can be configured to address Quality of Service, Priority between technologies and fault-tolerance through management layer.

摘要： A communication device (100) includes a plurality of communication units (103-1, 103-2) that transmit data in different transmission schemes from one another, a route selector (101) that searches for a most appropriate communication route and gives an instruction to transmit data from the communication unit corresponding to the most appropriate communication route, and a converter/sorter (102) that converts data into a format compatible with a transmission scheme of the most appropriate communication route and outputs the converted data to the communication unit indicated by the route selector (101), wherein the communication unit corresponding to the most appropriate communication route transmits the converted data. It is thereby possible to perform communications using the most appropriate communication route among a plurality of transmission schemes even in the case where an application is not compatible with the data format or protocol of the most appropriate communication route.

摘要： In a method for configuring a MAC address aging time, a first device generates a first Ethernet virtual private network EVPN protocol packet. The first EVPN protocol packet includes aging time information indicating a media access control (MAC) address aging time for an EVPN. The first device sends the first EVPN protocol packet to a second device. The second device configures the MAC address aging time based on the first EVPN protocol packet.

摘要： A network node, computer program, computer-readable medium and method for fail-safe data transmission in a network, in which data packets are transmitted from a sender to a receiver via redundant paths, upon which resources for the transmission are reserved at participating network nodes utilizing an identifier associated with the relevant path, wherein, if a new path is to be found for at least one of the paths involved, then the previous reservations on all redundant paths are maintained, a new redundant path is determined for the at least one path involved and an attempt is made to reserve resources for the transmission on this new redundant path at the participating network nodes, wherein a new identifier associated with the new path is utilized, and if the new reservations on the at least one new path are successful, then previous reservations on the at least one previous path involved are removed.

摘要： This disclosure describes techniques that include determining, at an egress node in an SRm6 network, how to process a packet that may arrive without a segment routing header and/or a compressed routing header. In one example, this disclosure describes a method that includes receiving, by an egress node of a segment routing network, segment routing advertisements; configuring, by the egress node and based on the segment routing advertisements, information enabling the egress node to recognize encapsulated packets arriving at the egress node without a compressed routing header; receiving, by the egress node, a packet that does not have a compressed routing header; and de-encapsulating, by the egress node and based on the stored information, the packet.

摘要： A first router in a first AS, the first router comprises: a processor configured to: obtain information about a broadcast link connecting the first router to a second router in a second AS, and generate a link state message comprising the information; and a transmitter coupled to the processor and configured to transmit the link state message to a third router, wherein the third router is in the first AS and is adjacent to the first router. A method comprises: receiving a first link state message from a first router; receiving a second link state message from a second router; receiving a third link state message from a third router; determining which of the first router, the second router, and the third router are ASBRs connected to a broadcast link based on information in the first link state message, the second link state message, and the third link state message.

摘要： Systems and methods for selecting tiering protocols based on data transmissions over mesh networks within defined spatial areas can be provided. A mesh network can be established within a defined spatial area. Each network device within the mesh network can be a user device or a supernode. Further, a wireless communication link can be established between the user devices and supernodes. A plurality of tiered protocols for tiering data transmissions can be accessed. Data to be transmitted over the mesh network can be analyzed to determine which tiered protocol to select. Path data that identifies a routing path from the a user device to a supernode can be generated, and the data can be transmitted according to the path data.
