ITU-T E.744

This Recommendation has four main purposes: 1) Provide guidelines for implementing standardized traffic and congestion control procedures in SS No. 7 and IN-structured networks. 2) Provide general guidelines on requirements that should be placed on network elements so that networks can be made robust to unforeseen problems. 3) Provide general principles and guidelines on how network level and network element level control should be structured to maximize effectiveness and avoid network problems. 4) Provide high-level requirements for traffic and congestion controls for consideration in developing specific procedures in other ITU-T Recommendations. Requirements and implementation considerations are covered for MTP, SCCP and IN traffic and congestion control procedures, and requirements are provided for adequate overload controls in network elements. In addition, considerations for making networks robust against failure propagation are discussed.
