1 Add ALCAP and NBAP as subdissectors of SSCOP. Previously it only knows about SSCF-NNI and data. (Changes in packet-sscop.c, packet-sscop.h) 2 Add capability for lower layer to force SSCOP to choose a particular dissector. It is passed as "subdissector" field of SSCOP protocol data. This is required because different payload protocol is distinguished by different VPI/VCI. There is no protocol field inside SSCOP frame. (Changes in packet-sscop.c, packet-sscop.h) 3 Make K12xx configuration file supporting the following syntax: C:\k1297\stacks\umts_iub\umts_iub_aal2l3.stk sscop:alcap This says dissect with SSCOP first and then pass to ALCAP. The change is made general, so it supports arbitrary number of protocol, like "proto1:proto2:proto3". Using ":" as separator allow us to expand the syntax further to support parameters like "proto1 param1:proto2 param2 param3". (Changes in packet-k12.c) With above 3 changes together, dissecting Iub traces are correct for control and signaling planes. I am still investigating user plane frames because writing UMTS RLC/MAC protocol dissector is required. The patch and sample .rf file (same as my previous patch) is in the attachment. plus: Add Kriang to the AUTHORS list (and once at it upate my own record) svn path=/trunk/; revision=20580
