•Supports GTP Traffic (GTP User Plane Data) which includes: verification like BERT testing, HTTP traffic generation capability, GGSN can actually be connected to real IP network to simulate Gateway testing
* GGSN: GGSN is the key equipment of GPRS network connecting other networks.
The AGTP resides in the GGSN and it communicates with the existing standard GTP-c module of the EGSN, SGSN and GGSN.
For a new interworking architecture to manage mobility, WiMAX accesses the ALL-IP core network through a Connectivity Services Network (CSN) gateway, UMTS through GGSN, CDMA2000 through PDSN, WLAN through GGSN emulator, LTE through S-GW (MAG) and P-GW (LMA) respectively.
The Flexi ISN, which performs GPRS Gateway Service Node (GGSN) and data charging functionalities, is fully integrated with the existing Nokia Siemens Networks charge@once prepaid solution to enable flexible charging of data services.
The versatility built into the Express DS 255 will also support over 200K individual encryption/compression sessions in high connectivity networking applications, such as 4G wireless Gateway GPRS Support Node (GGSN).
RadiSys' latest addition to its family of AdvancedTCA-compliant products features dual Intel IXP28xx network processors and is designed to address 10 Gbps wirespeed packet processing in network applications that demand high bandwidth throughput such as security gateways, GGSN, Broadband-Remote Access Servers, edge routers and session controllers.
Through RAP, TEMs (telecom equipment manufacturers) have access to integrated solutions that are ideal for carrier grade applications such as softswitches, SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), RNC (Radio Network Controllers) and VoIP (voice over IP) gateways, among others.
