Yin Zhencai. Design for and comparison between two CPCI-based high-availability signal gateway schemes[J]. 2007,(2):36-37. DOI: 10.13756/j.gtxyj.2007.02.011.
Signaling Gateway(SG) must have High Availability(HA) of 99.999% to meet the QoS requiremets of telecom operators and users.Based on the introduction of the CPCI platform
this paper intro-duces and analyses two schemes for achieving HA signaling gateways——load balance and active/standby
