A Local Area Network (LAN) is a computer network covering a local area, like a home, office, or group of buildings. Current LANs are most likely to be based on switched IEEE 802.3 Ethernet running at 10, 100 or 1,000 Mbit/s or on Wi-Fi technology . The defining characteristics of LANs in contrast to WANs are: their much higher data rates; smaller geographic range; and that they do not require leased telecommunication lines.
This white paper describes the surveillance video multicasting technology, highlights the benefits of IGMP as well as its integration in Korenix devices for assuring high quality video communication in surveillance applications.
Guests, contractors, vendors, business partners, and other temporary users require and expect certain level of network access within organizations that they visit. Corporate network access has been typically open; internal LAN connections have seldom required authentication. Today however, regulatory and other security concerns demand that organizations adopt a more secure posture towards these short-term users.
