Abstract: A cartridge for an aerosol provision device comprises a chamber for containing a liquid from which a flow of aerosol for inhalation by a user is generated. The cartridge comprises a first connector arrangement for releasably connecting the cartridge to a body portion of the device, and a second connector arrangement for releasably connecting to a container for a material. In use, aerosol flows through the material in the container before being inhaled by the user. The first connector arrangement is configurable in a locked configuration and in an un-locked configuration, and the first connector arrangement must be configured in the un-locked configuration for the cartridge to be removeable from the body portion. The first connector arrangement is configurable from the locked configuration to the un-locked configuration while the cartridge remains stationary with respect to the body portion.

Abstract: At least two different redundancy protocols are operated in parallel by network devices in an Ethernet network. Control is determined and assigned to one of two protocols to have total control over which ports in the network devices are active and which are blocked for transmission of user data and network data network traffic while allowing all control and monitor traffic to traverse the ring of network devices. Control and monitoring packets are transmitted by RSTP packets through all of the network devices in the ring while restricting the data ports of the network devices to transmit user data and data network traffic to the network devices connected in the line of the network devices. Parameters received in RSTP packets are collected from all of the network devices in the ring in order to determine which network device of the network devices is a virtual root bridge.

Abstract: The invention relates to a method for running a network, in particular an Ethernet network with redundancy properties, wherein the network has a ring network topology, in which network devices are connected to each other with the data ports thereof via data lines and exchange control data and user data by means of protocols via the data lines, wherein the protocols prevent the transmission of network traffic via certain data ports of individual network devices with the exception of network traffic for controlling and/or monitoring the media redundancy, in order to avoid an endless circulation of network traffic in physical loops of the network, wherein it is provided according to the invention that at least two different protocols are executed parallel to each other in the network on the network devices, wherein the parallel operation of the at least two redundancy protocols is enabled by the fact that the control over the data ports to be blocked is assigned to an individual redundancy, or the parameters for

Abstract: The invention relates to a method for redundantly and reactionlessly connecting networks to each other, such as communication networks, particularly Ethernet networks, wherein there is a plurality of network devices which communicate and exchange data with each other via data lines in the network which has at least one, preferably a plurality of network segments, characterized in that at least more than one RSTP protocol instance is implemented on the network devices for coupling network segments so that one network segment can be connected per RSTP protocol instance.

Abstract: The invention relates to a method for creating a DHCP network device configuration, wherein the parameter allocation by a DHCP server is performed using Option 82, and the assignment for the IP address to be allocated to a network device is determined on the basis of the topological information. The topological information is provided to the DHCP server by the requesting device and a DHCP relay agent, and the relay agent acts on each DHCP message sent by a device in the network by means of an additional DHCP Option 82 and sends the messages via unicast to the DHCP server, whereas the standard DHCP message is forwarded. According to the invention, a network device sends, in addition to the regular DHCP discovers via MAC broadcast, DHCP messages via MAC multicast to a MAC multicast address, and from this MAC multicast sends unique information via unicast to the DHCP server by means of a DHCP relay agent, since the associated network device filters the multicast.

Abstract: Configuration errors on interconnected network infrastructure devices are detected in a network where each network infrastructure device supplies information about its own configuration at its own network interface and sends this information to a neighboring network infrastructure device via a discovery protocol. Furthermore each network infrastructure device removes from the network the configuration data received at its interfaces in order to prevent this data from being passed on to other network infrastructure devices, and the received configuration data of the neighboring network infrastructure devices is stored as a data structure on one of the network infrastructure devices in a storage unit. The information about the neighboring network infrastructure devices is made available by the storage device of the first network infrastructure device and used to detect error configurations between the respective devices by comparison with the data deposited in the storage unit.
