GPRS Load Balancing
General packet radio service (GPRS) is the packet network infrastructure based on the European
Telecommunications Standards Institute (ETSI) Global System for Mobile Communication (GSM) phase 2+
standards for transferring packet data from the GSM mobile user to the packet data network (PDN). The
Cisco gateway GPRS support node (GGSN) interfaces with the serving GPRS support node (SGSN)
using the GPRS Tunneling Protocol (GTP), which in turn uses UDP for transport. IOS SLB provides
GPRS load balancing and increased reliability and availability for the GGSN.
