Juniper Networks WXC Project

Hey all,

sorry that i didn't post a lot the last month, but i was traveling for work and had some holiday.

Some post ago i talked about a project with WXC, now i want to show you some figures about the preformance of these devices in real network.

This is from a office to hq in the same country (so no latency problems).

This image clearly show that they don't use object caching, but Molecular Sequence Reduction™ (MSR™) compression and Network Sequence Caching technologies. the first one is in memory, the second on harddisks (MSR can be done by WX, but only NSC can be done by WXC)

why do i say you clearly see it doesn't use object caching? Because when you see the image you see that at 10/07/08 someone is asking a file with a size of +/- 4.5 gig and is compressed by almost 95% (so out of cache), this can also be done by object caching, BUT then someone needs to ask the same file before (which will need to pass the line 1 time compleetly). This is not the case here (you see clearly see in the image that never before there has been a request for a file larger then 500MB.).

Some other figures:

Compression Summary

Peak Data Compression 98,00%
Total Data Compression 86,10%
Total Bytes Into Compression 17,7 GB
Total Bytes Compressed 15,3 GB
Total Bytes Out of Compression 2,5 GB
Effective WAN Capacity 7,20 X

Wow, isn't this nice ! this means that from the 17,7 GB that is asked to pass the line only 2,5 GB Really crossed the line. and i can even say that from that 2,5 GB only 1.4 GB needed to pass the line, because 1.1 GB was bypassed because of license issues! (see below)

Passthrough Data
Category Bytes Packets
No Remote WX 79.253.312
By Filter Rule 675.185.052
Overflow 68.746.046
No Local Reducer 8.299
Non-IP 210.496
License Violation

But hey which traffic includes this figures?

Now you have a idea about which traffic it is. OK, i need to be clear about one thing, this is the best figure i have of all my sites :). BUT, still it is real traffic.
