Here, authentication -- services for infrastructure nodes are offered by the -- root node, the node providing WNS at the topmost -- (Campus) level. This node spans an enterprise campus -- that resides in a geographic location. In this case, -- an 802.11 station performs initial authentication -- with the topmost WNS entity. It also gets the keys -- needed for secure context transfer by communication -- with that entity. -- -- WNS are offered at various levels as shown in the -- hierarchy to achieve scalability. WNS at the -- subsequent levels other than the root level include -- authentication services for MNs and are typically -- confined to a single building. -- -- At the broadcast domain level, the WDS includes -- authentication and registration services for the APs. -- An AP provides proxy authentication and registration -- services for the MNs. The APs that connect to parent -- APs through the wireless interface ( as shown by the -- dotted lines ) are Repeater-APs. The WGBs are managed -- in the same manner as the MNs. However, the Ethernet -- Nodes ( EN ) that are connected to the WGB won't be -- served as part of the WDS. -- -- GLOSSARY -- -- Access Point ( AP ) -- -- Any entity that contains an 802.11 medium access -- control ( MAC ) and physical layer ( PHY ) interface -- and provides access to the distribution services via -- the wireless medium for associated clients. -- -- Wireless Bridge -- -- An 802.11 entity that provides wireless connectivity -- between two wired LAN segments and is used in point- -- to-point or point-to-multipoint configurations. -- -- Mobile Node ( MN ) -- -- A roaming 802.11 wireless device in a wireless -- network associated with an access point. -- -- -- WorkGroup Bridge ( WGB ) -- -- A work-group bridge is a non-STP AP with an 802.11 -- primary port and a secondary Ethernet port that -- provides access to a non-STP secondary Ethernet LAN -- segment. STP refers to the IEEE 802.1D Spanning Tree -- Protocol. An 'STP AP' executes the 802.1D STP and -- the 802.1D STP is operated on an 'STP link'. A -- 'non-STP AP' does not execute the 802.1D STP. -- -- Repeater-AP -- -- A repeater is a 'wireless AP' that is attached to a -- parent AP on an 802.11 primary port. The Ethernet -- port is disabled in a Repeater-AP. -- -- Infrastructure Node ( IN ) -- -- This term refers to Access Points, Wireless Bridges -- and those devices that implement and offer WNS and -- WDS as shown in the network hierarchy. -- -- Ethernet Node ( EN ) -- -- The node that gets the uplink to the Wireless AP -- via the WGB. This node connects to the WGB through -- its primary Ethernet port. -- -- Context -- -- The mobility context for an MN includes its current -- mobility bindings with the APs, IP/802 address -- bindings, cached configuration parameters, QoS state, -- IP group membership, authentication state, accounting -- statistics, and other dynamically derived protocol -- state information. -- -- Wireless Domain Services -- -- The set of services being offered at a particular -- broadcast domain that may be an IP subnet or a -- particular VLAN. The services include the following. -- -- 1. MN security credential caching to provide seamless, -- secure intra-subnet roaming. -- -- 2. Authenticated context transfer for roaming client -- within the subnet. -- -- Since, by definition, the WDS are bound to one subnet -- ( broadcast domain ), if implemented in a device -- spanning multiple subnets, the implementation should -- take care to provide separate set of services for -- each of the subnets. -- -- -- Wireless Network Services -- -- The set of services that can be visualized as being -- offered at various levels other than the lowest -- (subnet) level of a hierarchical campus network. -- -- At the topmost level, infrastructure authentication -- services for all the devices in the network that -- provide WNS and WDS are offered. In case if WNS are -- not distributed at several levels as shown in the -- hierarchy above and is confined to be offered only at -- a single topmost level, the services offered also -- include authentication services for the MNs. -- -- WNS Entity -- -- The logical entity that resides in an infrastructure -- node and offers WNS to the descendants of that -- infrastructure node in the wireless services -- hierarchy. -- -- WDS Entity -- -- The logical entity that resides in an infrastructure -- node and offers WDS to the descendants of that -- infrastructure node in the wireless services -- hierarchy. -- -- WS Entity -- -- Refers to one of WNS / WDS Entities. -- -- Parent Node -- -- The entity that immediately precedes an infrastructure -- node in the hierarchy. For mobile nodes, the parent -- APs provide proxy wireless services by talking to their -- immediate parent entities providing WDS. -- -- Root Node -- -- The entity that is at the highest level in the network -- hierarchy. The root node acts as the IN Authenticator -- for the infrastructure nodes. In case if WNS are not -- distributed, the root node also acts as the Mobile Node -- Authenticator ( See description below ). -- -- Descendant -- -- A node that is in the sub-tree of the campus hierarchy -- tree rooted at the node providing WNS at the campus -- level. -- -- Infrastructure Node ( IN ) Authenticator -- -- The logical entity that communicates with the AAA -- server and provides authentication services for the -- infrastructure nodes. Details of the IN Authenticator -- has to be configured in the device providing WDS -- manually. The AP learns about the IN Authenticator -- automatically upon registering with its immediate -- parent. The WDS also includes MN authentication -- services if the entity providing WDS is at the -- topmost level in the hierarchy. -- -- Mobile Node ( MN ) Authenticator -- -- The logical entity that communicates with the AAA -- server and provides authentication services for mobile -- nodes. An infrastructure node learns the whereabouts -- of the MN Authenticator from the root node. -- -- Wireless Network Manager ( WNM ) -- -- The network management system that manages the -- entire hierarchy of devices providing WNS and WDS. -- -- Advertisement -- -- The process by which the Access Points identify their -- parent entities providing WDS. APs listen to the -- advertisements of the WDS entities and gets registered -- with one of those entities to facilitate secured -- context transfer. -- -- WLCCP -- -- Wireless LAN Context Control Protocol. Used to -- establish and manage the network topology and -- securely manage the 'operational context' for mobile -- stations in a campus network. -- -- AAA -- -- Authentication, Authorization, Accounting -- -- The method by which users are authenticated, -- authorized and tracked to gain access and move about -- inside a network. A node will request network access -- through an appropriate protocol to an authentication -- server that provides protocols and services for -- providing authentication, authorization and session -- accounting. -- -- Service Set Identifier ( SSID ) -- -- 802.11 Service Set Identifier. An SSID identifies a -- set of mobile nodes grouped into a logical 'service -- set' and the APs that provide access for the service -- set. -- -- -- Wireless services at subnet level -- ================================= -- -- +========+ -- | | -- | WDS | ( Subnet level - Broadcast -- | | domain ) -- +========+ -- / \ -- / \ -- / \ -- / \ -- / \ -- \/ \/ -- +~-~-~+ +~-~-~+ -- + + + + -- + AP + + AP + -- + + + + -- +~-~-~+ +~-~-~+ -- . . . -- . . . -- . . . -- . . . -- . . . -- . . . -- \/ \/ \/ -- +......+ +-.-.-.+ +~-~-~-+ -- + + + + + + -- + MN + + WGB + + AP + -- + + + + + + -- +......+ +-.-.-.+ +~-~-~-+ -- -- -- The above diagram depicts how wireless services are -- being offered in a network rooted at the device -- implementing WDS.
