SIGTRAN - Protocol Analysis & System Integration

This book addresses the needs of everybody who needs a detailed understanding of SIGTRAN.
The book starts with an introduction to SIGTRAN and the related protocols and continues with the description of the QoS-requirements on SIGTRAN.
This part ends with a comparison of SIGTRAN and its alternatives (e.g. SIP, DIAMETER, …) on different interfaces.
The following part reviews important characteristics of the CCS7-protocol suite that SIGTRAN shall more or less replace. Focus is on SPC- and Global Title based routing procedures, SLS-based load sharing and MT-2 and MTP-3 management procedures.
The book continues with a detailed consideration of the SCTP. Among others we evaluate in detail the SCTP association establishment and security threats for SCTP.
Special focus is on SCTP association management procedures like HEARTBEAT, RTO-calculation, data transfer and acknowledgement (SACK) and congestion control.
This part concludes with the discussion of the optimum setting of SCTP-parameters like RTO.Initial, SACK-Delay, Path.Max.Retrans or RTO.Alpha.
The next chapter evaluates in detail various important adaptation layer protocols like M2PA, M2UA, M3UA and SUA.
This part includes the discussion of the N+K-redundancy concept and the related ASP-management procedures.
The final chapter deals with SIGTRAN problems and testing. Major focus is on the discussion of SIGTRAN-operation across so called “battlefield”-networks using IPsec and through NAT’s.
The book concludes with the discussion of suitable SIGTRAN-testing procedures for vendors and operators
