In tests performed at Cambium, maximum TCP tput was achieved using Mikrotik Bandwidth tester tool and two router boards on each end of an ePMP PTP link. OSPF up > ZT UP > routes propagated > ping test between network > OSPF route not flap. open ports 2000 (Bandwidth test server) & 5678 (Mikrotik Neighbour Discovery Protocol).
In this case, the lower the latency the higher the tput for a single TCP session test. MikroTiks RouterOS powers its business-grade RouterBOARD brand. I found that NetFlix would function at even lower rates but that Prime Video would not. This represents at least a ten-fold decrease in bandwidth utilization for APV. You want your MQTT to be able to publish some events coming out of RouterOS or react to some events on its suscribed topics. Limit Bandwidth via DHCP I chose 256Kb/s as a starting point this is about 115MB/hour. In the case of a single stream TCP session and a smaller TCP window size such as 8Kb, the latency of the link will impact the achievable tput, as predicted by the TCP Bandwidth-Delay product. for example, getting a MQTT container 'up' is 1 thing, but still Mikrotik will have to do RouterOS development for integration. Therefore, the lower tput observed over a single TCP link with a very small window size does not represent the overall capacity of the link and will not be an issue in a typical deployment. The performance of each single TCP session will vary depending on network conditions and TCP layer configuration parameters at each endpoint. Navigate to Networking / Routers / List, click on the edit button of the desired router to configure and select the 'Mikrotik' tab. In a real world backhaul or access point scenario, there will be multiple TCP sessions established over a link. TCP Window Scaling (RFC 1323 – TCP Extensions for High Performance) Disable it in the production environment: /tool bandwidth-server set enabledno DNS cache A router might have DNS cache enabled, which decreases resolving time for DNS requests from clients to remote servers. Attributes are supported by MikroTik RouterOS. It has been noted that TCP tput observed on an ePMP link is lower than the wireless link test tool or UDP tput when the test is performed using Mikrotik router boards and the built in bandwidth tester.Ĭambium believes that the lower TCP tput observed is in direct co-relation to both TCP layer configuration parameters as well as test conditions, all of which can contribute to the lower tput Bandwidth server A bandwidth server is used to test throughput between two MikroTik routers. Once the PAP authentication test has been successful, the next step for sites using Active Directory is.
