Full Discussion: Sampling pcap file

This is what I understood your requirement was (each line displays a count of IPs used in the current interval and count of new IPs introduced, ie not seen in the file up to this point).

The array GIP (Global IP) contains each IP seen in the file so far. Each time an IP not in this array is seen it's added to this array and the new counter is incremented.

Perhaps this is wrong, when I re-read your post it appears you only want those IPs not seen in the previous interval (as opposed to the whole file) is this correct?
Code:
Interval   IP
A           192.168.1.1
A           192.168.1.2
A           192.168.1.3
B           192.168.1.1
B           192.168.1.4
C           192.168.1.3
C           192.168.1.2

For Interval,Count,New should we get
Code:
A,3,3
B,2,1
C,2,2

or
Code:
A,3,3
B,2,1
C,2,0

aggregate-ios

AGGREGATE-IOS(1)                                              General Commands Manual                                             AGGREGATE-IOS(1)

NAME

       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters to help make them nice and short.

SYNOPSIS

       aggregate-ios <source_config >optimised_config

DESCRIPTION

       Takes  cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1).  Optimised filters are produced on std-
       out.

OPTIONS

       None.

DIAGNOSTICS

       Any diagnostics produced by aggregate(1) are passed through on stderr.

EXAMPLES

       The following configuration fragment:

         ip prefix-list AS65530 description Foo, Inc
         ip prefix-list AS65530 permit 10.1.0.0/16
         ip prefix-list AS65530 permit 10.2.0.0/16
         ip prefix-list AS65530 permit 10.2.1.0/24
         ip prefix-list AS65530 permit 10.3.0.0/16
         ip prefix-list AS65531 description Bar.Com
         ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
         ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
         ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

         ip prefix-list AS65530 permit 10.1.0.0/16 le 24
         ip prefix-list AS65530 permit 10.2.0.0/15 le 24
         ip prefix-list AS65531 permit 192.168.0.0/19 le 24
