hi! wireshark can draw call flows for sip voip calls (accessible through the menu Telephony/VoIP Calls). however, when the capture is large, containing tens of thousands of sip voip calls, wireshark becomes very slow at producing the list of calls and the call flows.
[SNIP]
the runtime decreased now to approx. 1 minute (pretty reasonable when compared to 10 hours)
Very impressive improvement.
I can publish the patches on bugzilla; however, the changes/tests have been explicitly targeted at sip voip calls. some of the data structures are global and used by _all_ voip protocol taps; it won't work correctly with dumps having also non-sip voip calls. pls. let me know your opinion.
Go ahead attaching your improvement on to bugzilla, with the appropriate explanation of limitations, as you did here. It's always interesting to see this stuff, which can inspire a generic solution.
Thanks, Jaap ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
