![]() ![]() Zero-configuration networking enables service discovery, address assignment, and name resolution for desktop computers, mobile devices, and network services.ĪirGroup also supports DLNA, a network standard that is derived from UPnP Universal Plug and Play. AirGroup allows administrators to set policy-based discovery and enables client devices to be location-aware. ![]() This inhibits the performance of services that rely on multicast traffic.Īruba addresses this challenge with AirGroup. network to preserve the airtime and battery life. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. Broadcast and multicast traffic are usually filtered out from a WLAN Wireless Local Area Network. The IP addresses in such networks are link-local scope multicast addresses and each query or advertisement can only be forwarded on its respective VLAN, but not across different VLANs. As a result, client devices on a specific VLAN cannot discover a service that resides on another VLAN. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. In large universities and enterprise networks, it is common for devices to connect to the network across VLANs Virtual Local Area Network. If a network includes a large number of client devices sending mDNS or SSDP queries, more bandwidth is consumed and therefore, the network performance is affected. In simple networks, like a home network, discovering devices and services is easier because there is just one subnet Subnet is the logical division of an IP network. ![]() Similarly, Android devices constantly send SSDP packets to locate DLNA services. mDNS works in conjunction with DNS Service Discovery (DNS-SD), a companion zero-configuration technique specified. The mDNS protocol uses IP multicast User Datagram Protocol (UDP) packets, and is implemented by the Apple Bonjour and Linux NSS-mDNS services. mDNS provides the ability to perform DNS-like operations on the local link in the absence of any conventional unicast DNS server. Apple devices constantly send mDNS Multicast Domain Name System. supported services on Apple and Android devices respectively. DLNA is a set of interoperability guidelines for sharing digital media among multimedia devices. AirGroup supports Bonjour-supported and DLNA Digital Living Network Alliance. AirGroup is a unique enterprise-class capability that leverages zero-configuration networking and allows devices to communicate over complex access network topologies. ![]()
