INTEGRATED DHCP SERVER WITH STANDARDS - BASED INTERFACES
The DHCP server allows the manage- ment of IP address pools and can, with the Alcatel-Lucent 5750 SSC, per- form policy-based authentication, IP address assignment, and subscriber- profile configuration based on DHCP options 82 and 67. The system keeps track of IP leases for established sub- scriber and service sessions using a high- speed, real-time database that can be replicated over redundant servers.
The Alcatel-Lucent 5750 SSC can also interwork with existing DHCP servers in relay mode and is fully capable of fulfilling the role of net- work access configuration function (NACF), as defined in the ETSI TISPAN architecture standards.
Abuilt-in a2 reference interface allows subscriber information to be shared with third-party systems or complementary Alcatel-Lucent TISPAN/IMS products. A functional enhancement is available for the DHCP server module, enabling it to provide the connectivity location function (CLF) with support of the e2 and e4 reference interfaces. The
Alcatel-Lucent 5750 SSC can there- fore offer a full implementation of the a2, e2 and e4 interfaces in the NASS.
IEEE 802.1X EAP/RADIUS SUPPORT
The Alcatel-Lucent 5750 SSC enables the authentication and configuration of user devices such as RGs that require EAP and 802.1x wireless access points such as WiFi. Legitimate RGs can be preconfigured with a certificate that is authenticated via the Alcatel-Lucent 5750 SSC prior to authorizing access at the dig- ital subscriber line access multiplexer (DSLAM) or aggregation node.
R A D I U S A A A S E R V I C E S
Legacy HSI-infrastructure consoli- dation and migration to Alcatel- Lucent’s TPSDA is supported using a fully featured, highly scalable and extensible RADIUS authentication server, with support for standardized as well as multivendor RADIUS attrib- ute configuration on legacy BRAS systems. RADIUS support includes change of authorization (CoA) for mid-session policy changes, to facil- itate dynamic bandwidth mangement and on-demand service upgrades.
