A communication apparatus includes a processor and a memory. The processor executes computer-readable instructions stored in the memory. The instructions instruct the communication apparatus to establish a first network including the communication apparatus and a first device. The instructions instruct the communication apparatus to establish a second network including the communication apparatus and a second device. The instructions instruct the communication apparatus to determine a target IP address. Determining the target IP address includes identifying a particular IP address, which is an IP address of the communication apparatus used in the second type network. Determining the target IP address includes generating the target IP address to be within a particular range using the particular IP address. The particular range is a range of IP addresses that are not available in the second type network. The instructions instruct the communication apparatus to assign the target IP address to the first device.

Technologies for switching network traffic include a network switch. The network switch includes one or more processors and communication circuitry coupled to the one or more processors. The communication circuitry is capable of switching network traffic of multiple link layer protocols. Additionally, the network switch includes one or more memory devices storing instructions that, when executed, cause the network switch to receive, with the communication circuitry through an optical connection, network traffic to be forwarded, and determine a link layer protocol of the received network traffic. The instructions additionally cause the network switch to forward the network traffic as a function of the determined link layer protocol. Other embodiments are also described and claimed.

In some embodiments, apparatuses and methods are provided herein useful to use with irrigation devices connected to a multi-wire path in an irrigation system. In some embodiments, there is provided a system for use with irrigation devices including a modulator configured to provide an output power signal modulated with data; a multi-wire interface coupled to the modulator and configured to electrically couple to the multi-wire path extending into a landscape and to which the irrigation devices are connected; and a control circuit configured to execute an automated device discovery process configured to cause the modulator to modulate data comprising a discovery message on the output power signal, the discovery message indicating a portion of an address to match and prompting a response from one or more of the irrigation devices in which a corresponding portion of the unique address matches the portion of the address to match.

A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.

An application server switching method, applied to a scenario in which a handover occurs between user plane network elements corresponding to a terminal device, includes obtaining, based on a user plane network element of the user plane network elements after the handover and a correspondence between the user plane network element and an address of a local application server of one or more application servers deployed on a network, the address of the local application server corresponding to the user plane network element after the handover. The correspondence between the user plane network element and the address of the local application server is used to indicate the address of the local application server. The method also includes sending the address of the local application server corresponding to the user plane network element after the handover.

An apparatus for a local area network includes a management communications bus, and at one of a plurality of logic nodes, logic circuitry. The management communications bus is for communication among the plurality of logic nodes, wherein respective node addresses for the plurality of logic nodes are conveyed using the management communications bus. The logic circuitry communicates information in a data/address field of the communications protocol with another of the plurality of logic nodes with reference to a subset of the predetermined set of patterned data bits in the data/address field to synchronize the transactions.
