Virtual LAN. A logical, not physical, group of devices, defined by software. VLANs allow network administrators to resegment their networks without physically rearranging the devices or network connections.
A VLAN is created when a bunch of physically connected ports are grouped together by network hardware that supports VLANs. These VLANs are each treated as completely separate entities and can only be joined together by a router. This scheme is useful for grouping departments together for security and minimizing network traffic.
network of computers that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN. VLANs are configured through software rather than hardware, which makes them extremely flexible. One of the biggest advantages of VLANs is that when a computer is physically moved to another location, it can stay on the same VLAN without any hardware reconfiguration.
A networking environment where users on physically independent LANs are interconnected in such a way that it appears as if they are on the same LAN (workgroup). This means that membership in a LAN environment is no longer constrained by geography. Membership to a Virtual LAN is defined administratively independent of the physical network topology and requires centralized administration. A Virtual LAN segment is a unique broadcast domain.
Virtual LAN A method of grouping together computers so that they can communicate with each other without interference from computers outside the VLAN. They do not have to be on the same physical network (hence “virtual” LAN). VLAN s can also separate computers that may be on the same physical network. This is a very powerful tool for network managers.
Virtual LAN - A network architecture which allows geographically distributed users to communicate as if they were on a single physical LAN by sharing a single broadcast and multicast domain. ATM forum LAN emulation supports VLANs.
A set of systems that, regardless of higher-layer addressing or location, is designated as a logical local-area network (LAN) and treated as a set of contiguous systems on a single LAN segment. VLANs can be proprietary or standardized using the Institute of Electrical and Electronics Engineers' 802.1q specification. Typical grouping parameters for VLANs include the port number of the hub, switch or router, the higher-layer protocol such as Internet Protocol (IP) or Internetwork Packet Exchange (IPX), the Media Access Control (MAC) address, and the traditional subnet. The goal of VLANs is to provide simpler administration and partitioning at the MAC layer. See LAN, IP and IPX.
A Virtual Local Area Network is a network of computers which function as if they were connected to the same network, even though they may be located in physically separate locations. VLAN's are configured using software, and can be mapped according to department, type of user, or primary application, rather than by geography. VLAN's offer flexibility to network administrators - workstations can move location without reconfiguration of their hardware.
Virtual LAN.VLANs, are a mechanism to determine which end stations should receive broadcast traffic, since it should not be sent arbitrarily to every connected user. Each packet transmitted by an end-station is assigned to a VLAN. An end-station only receives all the multicast and broadcast traffic on the LANs to which it belongs, and an end-station receives unicast traffic addressed to it on the VLAN to which it belongs.
Virtual LAN. Group of devices located on a number of different LAN segments that are configured (using management software) to communicate as if they were attached to the same wire. Because VLANs are based on logical instead of physical connections, they are extremely flexible.
Virtual Local Area Network. A LAN that maps stations on a basis other than location such as by department, user type or application. Managing traffic, workstations, and bandwidth can be easier with a VLAN and improve network efficiency. See a tutorial on Virtual Local Area Networks (VLANs)
Virtual local area network. A mature network technology that allows local area networks (LANs) to overlap on a single backbone architecture. VLANs allow different departments in a building to "share" the same switch and not have special hardware dedicated to it.
Virtual Local Area Network - the advent of switching technology has allowed for LANs to be seperated into logical pieces referred to as VLANs. These logical units are effectively seperate LANs using common networking hardware, but seperated by software running on the switches on the network.
Virtual Local Area Network. VLAN's are a common function of higher end switches. They allow segregation of ports on the switch into separate broadcast domains. This is generally done for security or performance reasons. In very large networks, the amount of broadcast traffic on the wire can inhibit the performance of the entire network. Segregating the network into multiple IP subnets and using VLAN's to separate the broadcast domain
Virtual Local Area Network refers to LANs that are interconnected by a virtual Layer 2. The NetEnforcer enables you to apply VLAN tags to its management traffic. VLANs are commonly used with campus environment networks. This enables network changes to be made without physically moving cables or equipment.
In a switched network, a logical collection of devices, such as workstations and servers with a particular IP subnet address, which are grouped into a broadcast domain. Usually, this domain is software based as opposed to a physical LAN, which is defined entirely by wiring.
Virtual Local Area Network - A software configuration that enables a network of computers to behave as if they are connected to the same wire even though they may actually be physically located on different segments of the local area network.
Virtual local area network, a method of segmenting traffic from individual users on an IP network so that those within the VLAN "see" each other on the network and can communicate and share files, printers and other peripherals locally -- while blocking interaction from others on the network
Virtual Local Area Network. A group of computers on a network whose software has been configured so that they behave as if they were on a separate Local Area Network (LAN). Computers on VLAN do not have to be physically located next to one another on the LAN. A VLAN can be set up as a temporary solution to allow a workgroup to use less network bandwidth and communicate more privately.
is a virtual LAN. In other words, connected devices behave as if they are connected to the same physical wire even thought they may be separated by a WAN connection. VLANs also help to improve network security over the WAN.
A network of computers that behave as if they were connected to the same wire even though they may be physcially located on different segments of the LAN—or even on a different LAN entirely. VLANs are configured through software rather than hardware, which makes them extremely flexible. The advantages of VLANs include increased performance, improved management, simplification of software configurations, and increased security.
Virtual LAN. VLANs allow departments that are dispersed at two or more locations to connect all their users to one departmental network. This overcomes the constraint that is associated with Local Area Networks ( LANs), which can only group together users who are located in the same geographical vicinity, such as a small building or one section of a building. PN Virtual Private Network.
Virtual Local Area Network. Virtual LANs allow a single physical LAN to be partitioned into several smaller logical LANs. VLANs limit the broadcast domain and thus improve stability and performance. AMS-IX operates several VLANs.
(Virtual LAN - Local Area Network) A virtual (or logical) LAN is a local area network with workstations defined some other way than by geographic location; that is, by department, type of user or primary application. The virtual LAN controller can change or add workstations and manage bandwidth allocation using network management software that relates the virtual picture of the LAN with the actual physical picture. VLANs are most likely to be used with campus (eg. several adjacent office buildings) environment networks.
(2003-10-28) Chris Limb Virtual Local Area Network. A group of PCs, servers and other network resources that are not necessarily on the same segment but communicate as though they were on the same wire.
virtual LAN. Group of devices on a LAN that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible.
Virtual local area network. A logical group of network devices that appear to be on the same LAN, regardless of their physical location. VLANs are configured with management software, and are extremely flexible because they are based on logical, rather than physical, connections.
