JadeOSprovidessolutionsofwirelesscontrollerandFITAP.
Wirelesscontrolleruniformlyconfigure,manageandmaintainalargequantityofAPs,
which greatly reduces the maintenance of wireless network. JadeOS supports AP
withoutconfiguration,whichisconvenienttoexpandFITAPandwirelessnetwork.
JadeOS also supports centralized authentication, which is convenient to uniformly
accessandauthenticate.Atthesametime,itisbettertodothefunctionofwireless 
roaming,RFmanagementandloadbalanceofAPaccessforAPcentralizedmanage‐
ment.
WiththestandardCAPWAPprotocol,ACmanagesandcontrolsAPthroughCAPWAP
control channel; the data for warding
 between AP and AC is through CAPWAP data
channel. For CAPWAP is transferred based on Layer‐3 network, it supports flexible
networkdeploymentinmultinetwork;withthestandardprotocol,itraisesthepos ‐
sibilityofinterconnectionbetweendifferentproductsfromdifferentmanufacturers.
Forwarding mode supports AC centralized forwarding and
AP local forwarding. Au‐
thentication mode supports AC centralized authentication and AP local authentica‐
tion.

Controlandprovisioningofwirelessaccesspoints(CAPWAP)protoc olisbelongingto
IETF.Itrulesthe interconnection  betweenWTP andAC,which achieve themanage‐
mentanddataforwardingforalltheWTPscontrolledbyAC.NowCAPWAPisclassi‐
fiedintotwotypes:
• CAPWAPcontrolchannel
• CAPWAPdatachannel
10.1.2CAPWAPCont rolChannel
CAPWAPcontrolchannelisclassifiedintotwotypes:
Staticdiscovery:specifytheIPaddressofACinAP
Dynamic discovery: configure broadcast discovery, DHCP discovery and DNS discov‐
eryandsooninAP
More, AP will actively require update version and configuration, which reduce the
