    Hope you must be fine by grace of God. I am facing a problem in my thesis which is about to change the link data rate depending upon the buffer occupancy i-e if the buffer space is filled above threshold then increase the link data rate and if the buffer is occupied below threshold then reduce the link data rate. Now the problem exists in determining the buffer space occupied. For this I am using” ifconfig” and “netstat”.
    For ifconfig the output for switch AS-1 eth1 is as follows (by using netstat I was getting the same output):
    AS-1-eth1 Link encap:Ethernet HWaddr 7a:81:df:f1:29:74
    inet6 addr: fe80::7881:dfff:fef1:2974/64 Scope: Link
    UP BROADCAST RUNNING MULTICAST MTU: 1500 Metric: 1
    RX packets: 88 errors: 0 dropped: 0 overruns: 0 frame: 0
    TX packets: 57 errors: 0 dropped: 0 overruns: 0 carrier: 0
    Collisions: 0 txqueuelen: 1000
    RX bytes: 12266 (12.2 KB) TX bytes: 9052 (9.0 KB)
    Now I am thinking, packets in queue= RX packets-TX packets=88-57=31packets (31 packets are in the buffer). Am I thinking in the right direction?
    For “ifconfig” kindly check the following link
