What is Diameter?
Diameter is an authentication, authorization, and accounting (AAA) protocol for computer networks. It evolved from RADIUS and provides a framework for AAA services in various applications, such as network access control, mobile IP, and Voice over IP (VoIP). Diameter is more reliable and scalable than RADIUS and supports secure transport protocols like TCP and SCTP.
What other technologies are related to Diameter?
Diameter Competitor Technologies
SS7
SS7 is a legacy signaling protocol used in telecommunications. Diameter is a more modern signaling protocol intended to replace some of SS7's functionality, making them competitors in some scenarios.
MAP
MAP (Mobile Application Part) is an SS7 protocol used for various functions in mobile networks, such as location management and SMS. Diameter (specifically S6a) provides similar functionalities in LTE networks, making them competitors.
ISUP
ISUP (ISDN User Part) is an SS7 protocol used for call control in telephone networks. Diameter, with protocols like SIP, offers a more modern alternative for call control, making them competitors.
INAP
INAP (Intelligent Network Application Part) is an SS7 protocol used for implementing intelligent network services. Diameter can be used to provide similar services in modern networks, making them competitors.
HLR
HLR (Home Location Register) is a central database in 2G/3G networks that stores subscriber information. The HSS in LTE serves a similar function, and Diameter (S6a interface) is used to access the HSS. Thus, HLR's function is fulfilled using Diameter in newer networks.
Diameter Complementary Technologies
SIGTRAN
SIGTRAN is a suite of protocols that transport SS7 signaling over IP networks. While Diameter operates at a different layer, using SIGTRAN can facilitate migration from SS7 to Diameter-based networks, or enable interworking between SS7 and Diameter, making them complementary.
GTP
GTP (GPRS Tunneling Protocol) is used for setting up tunnels in a mobile network and is used in conjunction with Diameter. Diameter (Gy, Gz) is used for charging control related to the tunnels created by GTP, making them complementary.
PCRF
The PCRF (Policy and Charging Rules Function) is a key component in 4G/5G networks that uses Diameter (Gx interface) to communicate with the PGW (Packet Gateway) for policy and charging control. Thus, PCRF and Diameter are tightly integrated.
