![]() ![]() Network discovery and selection procedures for 5GS do not differ much from EPS and the principles used when a 3GPP access type is selected, have been maintained.īefore the UE can receive and use the services and capabilities from the 5GS, e.g. Catherine Mulligan, in 5G Core Networks, 2020 7.2.1 Network discovery and selection The network discovery will verify whether there is at least one ZigBee router in any discovered network that currently permits joining. The information also includes the value of beacon order, superframe order of the networks, and their ZigBee stack profile identifiers. The network discovery operation delivers the list of discovered networks, including their PAN identifiers, current frequency channels, and the version of the ZigBee protocol used by the each network to the APL layer. Otherwise, the device will perform a passive scan. The active scan is the preferred scan method if the device is capable of performing an active scan. The NWK layer uses the MAC layer channel scanning to discover the presence of other networks. The device discovery request is given to the NWK layer by the APL layer. The network discovery procedure is used to discover all the networks currently operating in the device POS. Shahin Farahani, in ZigBee Wireless Networks and Transceivers, 2008 3.4.10.1 Network Discovery Network Discovery (WSD-Out) Creates an outbound rule to discover devices via Function Discovery on UDP port 3702. Network Discovery (WSD EventsSecure-Out) Creates an outbound rule to allow for Secure WSDAPI Events via Function Discovery on TCP port 5358. Network Discovery (WSD Events-Out) Creates an outbound rule to allow WSDAPI Events via Function Discovery on TCP port 5357. Network Discovery (UPnP-Out) Creates a second outbound rule to allow the use of Universal Plug and Play over TCP (all ports). Network Discovery (UPnPHost-Out) Creates an outbound rule to allow the use of Universal Plug and Play over TCP (all ports). Network Discovery (SSDP-Out) Creates an outbound rule to allow use of the Simple Service Discovery Protocol on UDP port 1900. Network Discovery (Pub WSD-Out) Creates an outbound rule to discover devices via Function Discovery on UDP port 3702. Network Discovery (NB-Name-Out) Creates an outbound rule to allow NetBIOS Name Resolution on UDP port 137. Network Discovery (NB-Datagram-Out) Creates an outbound rule to allow NetBIOS Datagram transmission and reception on UDP port 138. Network Discovery (LLMNR-UDP-Out) Creates an outbound rule to allow LLMNR on UDP port 5355. Network Discovery (LLMNR-TCP-Out) Creates an outbound rule to allow LLMNIL on TCP port 5355. Network Discovery (WSD-In) Creates an inbound rule to discover devices via Function Discovery on UDP port 3702.Įnabling Network Discovery opens the following outbound ports in the Windows Firewall: ■ Network Discovery (WSD EventsSecure-In) Creates an inbound rule to allow Secure WSDAPI Events via Function Discovery on TCP port 5358. Network Discovery (WSD Events-In) Creates an inbound rule to allow WSDAPI Events via Function Discovery on TCP port 5357. Network Discovery (UPnP-In) Creates an inbound rule to allow use of Universal Plug and Play on TCP port 2869. Network Discovery (SSDP-In) Creates an inbound rule to allow use of the Simple Service Discovery Protocol on UDP port 1900. Network Discovery (Pub-WSD-In) Creates an inbound rule to discover devices via Function Discovery on UDP port 3702. Network Discovery (NB-Name-In) Creates an inbound rule to allow NetBIOS Name Resolution on UDP port 137. Network Discovery (NB-Datagram-ln) Creates an inbound rule to allow NetBIOS Datagram transmission and reception on UDP port 138. Network Discovery (LLMNR-UDP-In) Creates an inbound rule to allow Link Local Multicast Name Resolution on UDP port 5355. Enabling Network Discovery opens the following inbound ports in the Windows Firewall: ■ Laptop users are prime examples of people who may find Network Discovery useful in their home networks as long as it is implemented correctly with Network Location Types. Windows Vista still uses the older method of announcing itself to previous Windows systems such as XP to provide backward compatibility. In finding other Windows Vista systems, it uses the Function Discovery Provider Host service and Web Services Dynamic Discovery (WS-Discovery). Network Discovery accomplishes the same thing it uses the Function Discovery Resource Publication service to publish the local computer and its attached resources (drive shares, printer shares, etc.). These broadcasts were also used to advertise what shares each system had. Previous versions of Windows used NetBIOS to announce their presence on the network. Network Discovery simplifies configuring and connecting network devices, primarily in small environments such as home offices and small offices. ![]()
