摘要： A solution is disclosed for providing automatic multicast address assignment and conflict resolution for AV streams multicast over a networked AV system. The solution includes a device for monitoring the system for messages associated with AV streams multicast over the system and implementing a conflict resolution protocol when a conflict of multicast addresses is detected, where the conflict resolution protocol utilizes automatically randomly selecting a preliminary multicast address from a defined range of addresses.

摘要： A method for communication includes provisioning each node in a network with a respective set of two or more network addresses. Each node in succession is assigned a respective network address from the respective provisioned set that has not been assigned for use by any preceding node. Upon finding for a given node that all the network addresses in the respective provisioned set were assigned to preceding nodes, the preceding nodes are searched to identify a candidate node having an additional network address in the respective provisioned set, other than the assigned respective network address, that was not yet assigned to any of the nodes. The additional network address is assigned to the candidate node instead of the respective network address that was previously assigned to the candidate node, and the assigning of the network addresses to the nodes in the succession resumes following the candidate node.

摘要： A Dynamic Host Configuration Protocol (DHCP) server includes a memory storing computer-readable instructions, and a processor configured to execute the computer-readable instructions to determine a media access control (MAC) address associated with a client, determine the MAC address associated with the client is a randomized MAC address, and assign an IP address the client from a DHCP IP server pool. The processor assigns an IP address to the client from a DHCP IP server pool using one of identifying, in a DHCP server table, at least one host name of the client and assigning a previously assigned IP address to the at least one host name of the client, and when the host name of the client is not available, assigning the IP address using a first lease with a first duration shorter than a default lease duration used for non-randomized MAC addresses.

摘要： A system and method are provided for a network device for use with a client device having a hostname and a MAC address. The network device contains a memory that has a second hostname and a second MAC address stored within the memory. The second MAC address corresponds to the second hostname. The memory also contains a processor configured to execute instructions stored on the memory to cause the network device to: receive, from the client device, the hostname and the MAC address; determine whether the MAC address is randomized; provide an instruction to the client device to inform a user of the client device that the client device hostname is registered when the hostname matches the second hostname and the MAC address is randomized.

摘要： A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

摘要： A method for performing self-assignment Layer 2 address acquisition implemented by a client device. The method includes the client device selecting a Media Access Control (MAC) address and generating an outgoing test message that includes a first hash token to test an availability of the selected MAC address. The first hash token includes a K generation hash (HK) value of a seed known only to the client device, where K is an integer value greater than one. The method further includes the client device sending the outgoing test message; determining based on a response to the outgoing test message or a lack of a response to the outgoing test message that the selected MAC address is not in use, and using the selected MAC address based on the determination that the selected MAC address is not in use.

摘要： Methods and apparatuses are described for dynamic medium access control (MAC) address distribution in a wireless network. A station (STA) may receive, from an access point (AP), a frame that includes an indicator indicating at least one MAC address type or MAC address policy supported by an extended service set (ESS) associated with the AP. The indicator may comprise an 8 bit bitmap. The STA may then transmit, to the AP, a request message that includes MAC Address Assignment Protocol information determined based on the at least one MAC address type or MAC address policy. The STA may receive a response message that includes a local medium access control (MAC) address assigned based on the MAC Address Assignment Protocol information. The STA may transmit, to the AP, an association request frame with the local MAC address.

摘要： A method of self-assigning an IP address to an item of pool or spa equipment can include randomly selecting, by the item of pool or spa equipment, an IP address from a predetermined IP address range. The method can also include transmitting, by the item of pool or spa equipment, the IP address and a serial number to a target parent node. Additionally, the method can include listening, by the item of pool or spa equipment, for a broadcast topology message from the target parent node. Further, the method can include determining, by the item of pool or spa equipment, that the IP address is valid based on the broadcast topology message and, upon determining that the IP address is valid, completing a startup process by the item of pool or spa equipment.

摘要： In a method for monitoring or tracking between mobile devices of a same group, mobile devices broadcast messages in broadcast mode over a radio interface in compliance with a short-range digital communication protocol. The messages can be received by all other mobile devices in the vicinity and can communicate according to the protocol. The messages include encrypted data encrypted using at least one identifier of the emitter device and a seed intended for single use or having a short period of validity. The encrypted data can only be decrypted by a limited group of devices. The mobile devices receive messages broadcast by other devices and decrypt the messages intended for a group to which they belong. If the protocol provides that the message includes an address field of the emitter device, this field is filled with a randomised address intended for single use or having a short period of use.

摘要： A computer network includes a claimant configured to send a first discover message to a first identifying address. The first identifying address identifies a first plurality of claimed addresses for potential use by the claimant as network source or destination addresses. Methods and computer program products for claiming network addresses are also described.
