  3.1.16 MulticastSubnet
  MulticastSubnet a network that allows multicast packets to be sent to all nodes connected to the network. Note 1 to entry: a MulticastSubnet is not necessarily the same

  4.2.2 Hosts with a LocalDiscoveryServer
  registration ensures that the applications are visible for local discovery (see 4.3.3 ) and MulticastSubnet discovery if the LDS is a LDS-ME (see 4.3.4 ). The OPC UA Standard

  4.2.3 Hosts without a LocalDiscoveryServer
  implementing an LDS-ME, they should also announce themselves on the MulticastSubnet with a basic MulticastExtension . This requires a small subset of an mDNS Responder (see mDNS and Annex

  4.3.4 MulticastSubnet Discovery
  MulticastSubnet Discovery In some situations, Clients will not know which hosts have Servers . In these situations, the Client will look for a LocalDiscoveryServer with the MulticastExtension on its local host ... requests a list of DiscoveryUrls for Servers and DiscoveryServers available on the MulticastSubnet . The discovery process for this scenario is illustrated in Figure 4 . Figure 4 - The MulticastSubnet Discovery Process

  4.3.6 Combined Discovery Process for Clients
  also be called on a remote LDS which is part of a different MulticastSubnet . An out-of-band mechanism is a way to find a URL or a HostName that

  5.1 Overview
  will announce all applications that it knows about on the local MulticastSubnet . In order to support this, a LocalDiscoveryServer supports the RegisterServer2 Service defined in OPC 10000-4 . For backward

  5.3.1 Overview
  used in many different network architectures. The following three architectures are Illustrated: Single MulticastSubnet ; Multiple MulticastSubnets ; No MulticastSubnet (or multiple MulticastSubnets with exactly one host each); A MulticastSubnet ... from the other hosts on the segment. A physical LAN segment is typically a MulticastSubnet unless the administrator has specifically disabled multicast communication. In some cases multiple physical LAN segments

  5.3.2 Single MulticastSubnet
  Single MulticastSubnet The Single MulticastSubnet Architecture is shown in Figure 8 . Figure 8 - The Single MulticastSubnet Architecture In this architecture every host has an LDS-ME and uses mDNS ... maintain a cache of the applications on the MulticastSubnet . A Client can call FindServersOnNetwork on any LDS-ME and receive the same set of applications. When a Client calls FindServers

  5.3.3 Multiple MulticastSubnet
  Multiple MulticastSubnet The Multiple MulticastSubnet Architecture is shown in Figure 9 . Figure 9 - The Multiple MulticastSubnet Architecture This architecture is the same as the previous architecture except in this architecture ... connected to. A Client that wants to connect to a remote MulticastSubnet shall use out of band discovery (i.e. manual entry) of a HostName or DiscoveryUrl . Once a Client finds

  5.3.4 No MulticastSubnet
  MulticastSubnet The No MulticastSubnet Architecture is shown in Figure 10 . Figure 10 - The No MulticastSubnet Architecture In this architecture the mDNS is not used at all because the Administrator

  5.3.5 Domain Names and MulticastSubnets
  fully qualified domain names for all computers that are accessed by Clients outside the MulticastSubnet . Servers configured with fully qualified domain names should specify the fully qualified domain name
