No ingress qos for udp
Speed test di mikrotik – mikrotik tutorial [eng sub
Actually, @LeTran, since you’re only bridging, you don’t need the first script at all… the first script is just for people who use the router to do routing and firewalling… you’re bridging between eth0.3 and eth1.2 and trying to DSCP tag in the middle… so you have a different requirement and don’t need any firewall since there’s a separate system doing all the bridging…
I’d start with cake and diffserv4, and then use dscp tag cs5, which places your game traffic in the high priority tin, ensuring at least 25% of the bandwidth. If you use diffserv3, it’s not good enough, and if you use diffserv8, it’s far too fine.
Btw, in regards to dual-srchost and dual-dsthost, based on your connection, dual-srchost or dual-dsthost seems to provide fairness to all users, so that torrenting by one user does not affect the others? Do I still need dual-srchost or dual-dsthost now that we’ve added a tag for gaming packet? Because of their torrenting and uploading, it’s fine for everyone else to be late.
Even if my firewall has any traffic shaping/policing rules in place, it would simply trigger ingress packets to be queued or lost, and the external sender to resend the dropped packets (consuming more bandwidth for a longer time?)
Shaping ingress traffic as it exits your router and enters your network doesn’t accomplish much because the bandwidth available to your network is likely greater than the bandwidth available to your router from the WAN.
Dropping TCP packets would cause the TCP receiver to skip segments and not ACK the missing segments, resulting in the segments becoming resent and the TCP sender slowing things down. As opposed to egress traffic shaping, where particular bandwidth numbers or percentages of total bandwidth can be assigned to various traffic flows, this is inexact.
Yes, it will take longer for TCP to send anything to your network, but it will do so at a slower pace (with less bandwidth), allowing other inbound traffic to pass. It can potentially use less bandwidth but use more data for a longer period of time. Don’t get the terms bandwidth and data consumption mixed up. Bandwidth refers to the maximum number of bits a connection can accommodate per second, while data consumption refers to the amount of data sent or received over time. They are two entirely different words, and often people get them mixed up.
In IP networks, QoS (Quality of Service) refers to the quality of individual transmission channels. This refers to allocating specific resources to specific programs or communication styles in order for them to function properly. To achieve a sufficient level of communication, for example, the required bandwidth must be given to transmit audio or video data in real time. At the same time, slower data transfer via FTP or e-mail does not jeopardize the transmission process’ overall performance (file or e-mail transfer).
Filtering is done solely on the basis of features in each data packet, such as the sender and receiver IP addresses defined in the header, the specified Ethernet protocol, the specified IP protocol, the specified TOS/DSCP value, and/or the VLAN ID (if VLANs have been set up). Since each data packet must be checked to see if the filter rules apply, the list of filter rules should be kept as short as possible. Otherwise, the time spent filtering could be greater than the time saved by establishing the filter.
Vxlan | part 2 – header format and encapsulation
Have you ever felt you knew a subject fairly well before someone uses words you’re unfamiliar with? People who work on MEF accredited networks use different terms than those who use Cisco regularly or live outside the MEF world. Even if we both understand the principles, communicating and having the correct end result would be challenging if we don’t speak the same language.
Some of the QoS-related material in the CCDE written at Cisco Live felt a little off to me. This shocked me because I have a lot of faith in QoS. My guess is that some of the content was written by someone with a different background, and some of the wording sounded a little strange to me. I wanted to read through some of the MEF content in order to expand my QoS horizons and learn about other concepts. At the very least, I’ll have gained new knowledge.
To begin, we have flows in our networks, and these flows have varying requirements for delay, jitter, and packet loss. I’ll write various words and say which are MEF terms; the other terms would be linked to what Cisco calls them or what they will be called in general outside of the MEF environment.
