Script shell calculate mean arrival request duration

hello,
I have implemented this command :
Code:
tshark -eth0 -T fiels -e frame.time et sip.Request-Line -z sip,stat > test2.txt

the result of this command : test.txt:
Code:
Aug 27, 2013 23:06:47.334270000	INVITE	
Aug 27, 2013 23:06:47.335045000	 SIP/2.0 401 Unauthorized 
Aug 27, 2013 23:06:47.336897000	ACK	
Aug 27, 2013 23:06:47.350187000	INVITE	
Aug 27, 2013 23:06:47.351728000	 SIP/2.0 100 Trying 
Aug 27, 2013 23:06:47.354311000	INVITE	
Aug 27, 2013 23:06:47.500954000	 SIP/2.0 180 Ringing 
Aug 27, 2013 23:06:47.504776000	 SIP/2.0 180 Ringing 
Aug 27, 2013 23:06:48.415368000	CANCEL	
Aug 27, 2013 23:06:48.416001000	 SIP/2.0 487 Request Terminated 
Aug 27, 2013 23:06:48.416193000	 SIP/2.0 200 OK 
Aug 27, 2013 23:06:48.416522000	CANCEL	
Aug 27, 2013 23:06:48.424779000	ACK	
Aug 27, 2013 23:06:48.590352000	 SIP/2.0 200 OK 
Aug 27, 2013 23:06:48.590370000	 SIP/2.0 487 Request Terminated 
Aug 27, 2013 23:06:48.595704000	ACK

so this file presents the arrival time and the name of the request or response of the sip protocol.
my purpose is to calculate :
1) the mean time duration of request = sum ( arrival_time_current_request - arrival_time_previous-request) / ( total number of request)

given that a sip request can be : ack, invite,cancel

1) I will repeat the same think with response :the mean time duration of response = sum ( arrival_time_current_resonset - arrival_time_previous-response) / ( total number of response)


given that a sip response can be : 180Ringing,200ok....etc

Thanks you.

sip_create_response(3SIP)			   Session Initiation Protocol Library Functions			 sip_create_response(3SIP)

NAME
sip_create_response - create a response for a SIP request SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> sip_msg_t sip_create_response(sip_msg_t sip_request, int response_code, char *response_phase, char *totag, char *contact_uri); DESCRIPTION
The sip_create_response() function creates and returns a SIP message in response to the SIP request sip_request. The response line in the resulting SIP message is created using the response code in response_code and the phrase in response_phrase. The response line has the SIP- Version of "2.0". If a non-null totag is specified, the resulting SIP response has a TO header with a tag value from totag. If totag is null and the response_code is anything other than 100 (TRYING), sip_create_response() adds a TO header with a randomly generated tag value. If the response_code is 100 and totag is null, the SIP response has a TO header without a tag parameter. If contact_uri is non-null, a CON- TACT header is added to the SIP response with the URI specified in contact_uri. The SIP response has the following headers copied from sip_request: All VIA headers FROM header TO header (with tag added, if required, as stated above) CALL-ID header CSEQ header All RECORD-ROUTE headers RETURN VALUES
The sip_create_response() function returns the resulting SIP message on success and NULL on failure. The value of errno is not changed by these calls in the event of an error. ATTRIBUTES
