It depends. We use it at links where speed changes. E.g. 100M to 1G or Ethernet to wireless. There it helps to reduce the impact of bursty traffic.
My friend, you always seem to be able to give me good advice.
We are improving our network lately a lot with OSPF and PPP tunnels to clients and at the same time upgrading hardware and improving wireless links.
But we get a 'feeling' that the better we make the network, the more complaints we get from people saying 'the internet is sooo slow...!'
We are breaking our heads over this since MT's bandwidth tests from MT cpe's always show very good results towards our end router.
Even tests done from a laptop show good, (not the same as very good) results.
or other tcp downloads are mostly only 50% of the same speeds....
Even our CCR that connects to the Cisco of our provider with the 300/300Mb line is not able to produce single downloads reaching even near this limits. If I run a single tcp download from my powerfull PC that has an 'unlimited' queue set I only get 100, 150Mbps in at best. Sometimes way less. Only if we open several multi stream downloads with a multi download stream program we in the end reach 280-290Mbps downloads...... we are a bit puzzled by why this is as it is....
So today we discovered some threads about the 'traffic flow' which in all our network is by default 'off'. (All MT network)
Our network has indeed a mixture of fast Ethernet and gigabit Ethernet in any 'route' traffic flows to reach remote client. Many routers that make wireless backhauls have on one end either a Gb Ethernet or a fast Ethernet where not always the wireless links themselves can produce 100Mbps (let alone Giga!). Like the links between AP and client for instance.
Plus the fact Ethernet is full duplex where wifi is simulated level 3 duplex at best but 98% is just simplex.
So we where hoping this traffic flow switch might bring us salvation..... until I've red someone that said it will kill VoIP!
We don't have a lot of VoIP clients (Is Skype VoIP?? If so then we do have al lot more...) but these that have are also the better paying ones. We wouldn't want to waste these clients....
Show your appreciation of this post by giving me Karma! Thanks.
