[e2e] packet reordering in OC 48 links

[S.Govind]

hi all


I have currently programmed the intel IXP 2400 Network Processor for IPv4 
forwarding.
Iam able to support line rates up to 3 Gbps (without any QoS provisioning) 
but an area of concern is the reordering, i obtain reordering up to 33% 
(ie: 33 % packets are reordered )for a link with 4000 flows a second 
each TCP flow of size 6.4 KB and 14% reordering for flow size of 640 B.

The packets are assumed to be arriving at a constant interval of time and 
of constant size (64 B ), this assumption is used for DoS attacks.

I am novice in networking, i have a few queries regarding the above 
results.

Are these numbers (reordering) indicative of current OC 48 links, 


Any comments and/or suggestions on the above  is most welcome

Thanking You,
Govind
