I wonder if anyone here can help me understand the output from TRACERT.

I understand the basics - what tracert does, the hops, TTL, network nodes - what does puzzle me is the times given.

I have spent some time googling and visiting many sites which attempt to explain 'tracert' but I find they just tell me what I already know and stop just when it starts to get interesting.

If you look at this tracert to www.jolt.co.uk

1 <1 ms <1 ms <1 ms 192.168.0.1
2 53 ms 53 ms 53 ms cr1.sdhrshm.uk.easynet.net [195.189.159.65]
3 41 ms 39 ms 39 ms 82.111.103.1
4 40 ms 40 ms 41 ms ge1-3-0-41.br1.enwkg.uk.easynet.net [82.110.108.161]
5 41 ms 41 ms 41 ms ge3-1-0-0.br0.bllon.uk.easynet.net [195.172.211.74]
6 41 ms 42 ms 42 ms ge0-1-1.er3.bllon.uk.easynet.net [212.135.12.41]
7 42 ms 42 ms 42 ms ge2-0-0.er3.thlon.uk.easynet.net [82.108.6.153]
8 41 ms 42 ms 42 ms te1-3.cr05.tn5.bb.pipex.net [195.66.224.29]
9 42 ms 42 ms 42 ms g1-1-6.er01.tn5.bb.pipex.net [62.72.140.142]
10 42 ms 72 ms 42 ms ge-0-0-0-3801.jolt-gw.cust.pipex.net [212.241.241.14]
11 43 ms 42 ms 42 ms secure.jolt.co.uk [82.133.85.65]

It's evident that there are 11 hops
1 = my router
2 = local exchange
4-7 = easynet (sky) infrastructure
8-10 = pipex infrastructure which hosts the jolt server
11 = jolt server

I know that if I ping www.jolt.co.uk I get consistent results around the 42mS mark.

So my specific questions are:

(1) Why are there three columns of times?
(2) Why do some intermediate hops show times which are bigger that the overall ping? In this case hop 2 is 53mS where the overall ping is just 42mS

It is this second question that puzzles me the most. It is common to see this.

Cheers,
