That question could take several lengthy dissertations to answer but I will boil it down to its essence. There are four functional areas within the mobile telecom operations center where one should deploy NetScaler. First is the carrier control plane where the usage auditing, billing, and authentication, authorization and accounting (AAA) reside. Here, NetScaler is ideal for providing AAA server load balancing and supports both DIAMETER and RADIUS protocols.
The second location is where the mobile carrier hosted applications reside. NetScaler provides a wide range of optimization benefits for apps including content switching, application server load balancing, TCP and HTTP optimization, and application caching for starters. On top of this, NetScaler provides AppExpert rate controls to manage subscriber use limits and server push support to improve application delivery.
The third location for NetScaler is in the mobile packet core network; here it is all about massive transmission of data through elements such as GGSN routers. In this core the traffic fairness and data offload facets of NetScaler are highlighted. Offloading SSL and TCP/IP protocol stack communication overhead along with priority queuing make packet processing and forwarding much more efficient. The NetScaler MPX 20500 provides over 40 Gbps; with clustering of multiple nodes the aggregate Layer 7 throughput reaches over a terabit/second.
Finally, all these mobile communication packets usually pass by the carrier cache farm on the way to and from the Internet. NetScaler provides cache server load balancing and N-tier multi-layer cache re-direction.
Many telecom operations require or strongly prefer NEBS certified equipment in most of these installations. With NEBS NetScaler is not just for Enterprise or XenApp/XenDesktop or Internet-centric or Social Networking or E-Commerce installations anymore!
