Universal Plug and Play (UPnP)
a set of computer network protocols promulgated by the
UPnP Forum. The goals of UPnP are to allow devices to connect seamlessly and to simplify the
implementation of networks in the home (data sharing, communications, and entertainment) and
corporate environments. UPnP achieves this by defining and publishing UPnP device control
protocols built upon open, Internet-based communication standards.
Windows Internet Naming Service (WINS)
is Microsoft’s implementation of NetBIOS Name
Server (NBNS) on Windows, a name server and service for NetBIOS computer names. Effectively,
it is to NetBIOS names what DNS is to domain names - a central store for information, However
the stores of information have always been automatically (e.g. at workstation boot) dynamically
updated so that when a client needs to contact a computer on the network it can get its update
normally DHCP allocated address. Networks normally have more than one WINS server and each
WINS server should be in push pull replication, the favoured replication model is the HUB and
SPOKE, and thus the WINS design is not central but distributed, each WINS server holds a full
copy of every other related WINS system records. There is no hierarchy in WINS (unlike DNS) but
like DNS its database can be queried for the address to contact rather than broadcasting a request
for which address to contact. The system therefore reduces broadcast traffic on the network,
however replication traffic can add to WAN / LAN traffic.
