The wireless controllers
The wireless controllers
{Administrators|Superiors} play an important role in enterprise networks. {They will|That they} may be {associated with|connected to|related to} an OEM or independent. In the former case, the characteristics are complementary to those in the gain access to point {and the ones|and people|and others} in the controller. {The main|The|Difficulties} drawback is having to stay in the lap of the OEM. Open controllers allow connection of most {light-weight|light|light and portable} access points and are much more open.
The main functions of a controller are:
- {Control|Deal with|Take care of} the transmit power of the access points to {permit} them decrease or dependent increase in electromagnetic field or failures more access points.
- {Control|Deal with|Take care of} the choice of eq to suit the {rate of recurrence|regularity|consistency} plan at access {factors|details|items}.
- Manage security problems, by introducing an authentication server in the {control|control mechanism}.
- Manage intercellular {passing|passageway|verse} problems (handover) between different cells, even if they happen to be not from the same technology.
- Implement nomadic management software for assigning {afflicted|damaged} users the access accord and the services to which {they may be|they can be|they are really} entitled.
To go a little further in this new {era|technology} of management of nomadism, take those example of UCOPIA controller that is shown in Figure.
{Almost all|Most|Every} traffic from the {cellular|cordless} user is redirected to the UCOPIA controller, which is a logical {failing|inability} (or physical) access {factors|details|items} between a park and the wired network. The controller filters the {Wi fi|Wifi} stream to apply the security policies defined and nomadism with UCOPIA {Supervisor|Administrator|Director}. The controller complies with the 802. 11i standard. The authentication protocol between the wireless user {channels|areas} and UCOPIA controller {is founded on|is dependent on|will be based upon} 802. 1x / EAP or HTTPS. Flows are encrypted or in TKIP or AES. In addition, an IPsec-based VPN can be established between the wireless client and the controller. The RADIUS authentication server and the {Supervisor|Administrator|Director} UCOPIA connect to LDAP directories or through the LDAPS secure protocol.
The UCOPIA solution allows very precise management of the addressing mechanism on the wireless network, depending on their profile and the controller configuration. One {likelihood is|opportunity is} to direct their traffic {in several} VLANs on the wired network controller {result|end result|outcome}. Companies often architecting their network VLAN to separate users, it is important to ensure consistency between the wireless and {born|cabled} infrastructures and {always|carry on and|still} {advantage|profit|gain} from the network {remoteness|solitude|seclusion} mechanisms on the {born|cabled} network. The Wi-Fi {part|aspect|area}, the network organization can benefit from structured VLANs by encapsulating the SSID and VLAN by {merging|incorporating} theirdifferentiated address ranges.
The solution in environment UCOPIA multisided can be {used|implemented|stationed} with one or more UCOPIA controllers. The remotes can be centralized on a site or {allocated|sent out|given away} across different sites. {Irrespective|No matter} of the architecture of controllers directories {can be|can even be} central or replicated to each site. For sites {faraway|isolated|far away} including few access {factors|details|items} or {linked} to {the key} site by a level 3 network connection, UCOPIA offers a bridge for establishing a tunnel emulating level 2 link between the remote site and {the key} site. Thus, the remote terminals are {handled|maintained|been able} centrally without local {control|control mechanism}. UCOPIA The solution includes all modules necessary for its functioning, which {permits} it to be {suggested|recommended|offered} in a mode "turnkey" {quite simple|very easy|quite easy} to implement. This kind of packaging is {well suited for|suitable for} small businesses or remote {twigs|divisions|limbs} of {a huge|a sizable} company, having few needs and means of integration. Conversely, large enterprises with complex network infrastructures, wish to {recycle|recycling} solutions already deployed in {conditions} of security or network organization.
With {the|their|it is} open and modular {structures|structure|buildings}, UCOPIA can integrate {effortlessly|easily|flawlessly} into existing network architectures and interoperate with the tools {in position|set up} (LDAP, RADIUS server, VPN, DHCP, PKI, etc. ).
