To overcome this, we propose a new Hash IP algorithm dubbed HDW in network load balancing (NLB) to increase network’s efficiency, availability and scalability. We achieve the new Hash IP load balancing algorithm via a constructive merger with … Web5. Beware that IPerf defaults to an "upload" test: The IPerf client ( -c) sends TCP data to the IPerf server ( -s ). It looks like you were running the client on your LAN and connecting to an IPerf server hosted on the public Internet, so you were testing your new broadband connection's upload, not download, speed. did andrew carnegie give money to charity
