Tracing Method with Intra and Inter Protocols Correlation

Abstract

MEGACO or H.248 is a protocol enabling acentralized Softswitch (or MGC) to control MGsbetween Voice over Packet (VoP) networks andtraditional ones. To analyze much deeper the realimplementations it is useful to use a tracing systemwith intra and inter protocols correlation. For thisreason in the case of MEGACO-H.248 it is necessaryto find the appropriate method of correlation with allprotocols involved. Starting from Rel4 a separation ofCP (Control Plane) and UP (User Plane) managementwithin the networks appears. MEGACO protocol playsan important role in the migration to the new releasesor from monolithic platform to a network withdistributed components.
