SDWAN - Control SMB file transfer traffic

Hi, I have a 300Mbps WAN link. I have below queries

 

1 If I have just one PC on network which is allowed to do a file transfer to one of the DC server. Whether this transfer can utilize the full bandwidth of 300Mbps - Means transfer rate at around 38mB/Sec (Assume I haven't configured any traffic shaper).  Or is there any default mechanism available in Fortigate to not allow these kind of burst traffic within stipulated time?.. My thought is , if there is no mechanism and without traffic shaper, two or three PCs on network can easily utilize this full bandwidth leaving very less bandwidth for other applications. I can understand that we can limit this with traffic shaper, but I would like to know whether any default mechanism available to control this (Like token/bucket limit etc).

 

2. My second query is , even if I do traffic shaping and restricting the bandwidth to 50Mbps. There is a chance that first few clients starting the file transfer can easily occupy the bandwidth. On this scenario, how we can control the traffic spikes for each client. (Without per-IP shaper).

 

Regards

Raja

1. TCP congestion mechanisms are sufficient to slow down traffic when saturation is reached. No other mechanism exists in FortiGate (to my knowledge). 

2.  You can set up a guaranteed BW in the traffic shaper

Thank you Alex

NESA

Did you fix your problem?

No, I am just controlling this burst with some bandwidth allocation for such traffics.. (Like SMB)
