Latency (defined as the average time it takes a network packet to travel from you, to a server, and back) is that lag you can sometimes see online, be it in a web page download stuttering or game struggling to keep up.” IND (Interpolation Delay) is in some games Stat’s Display. IND is the small buffer of time between when your client gets information from the server, and when it's shown to you in the game. This is normally around 50-60ms for normal games. RTT (RounD Trip Time) https://www.imperva.com/learn/performance/round-trip-time-rtt/ Round-trip time (RTT) is the duration, measured in milliseconds, from when a browser sends a request to when it receives a response from a server. It’s a key performance metric for web applications and one of the main factors, along with Time to First Byte (TTFB), when measuring page load time and network latency Protocols Online gaming uses TCP for non-critical traffic such as chat, game lobbies, etc. The Game traffic uses UDP. 3 ©2019 Extreme Networks, Inc.

All rights reserved Esports: A Network Focus Cloud/ISP “According to the PCMag Gaming Quality index, anything over 1 or 2 Mbps download speed is going to be sufficient for most online gaming. The hard work of making a game look good and run smoothly is, after all, handled by the hard drives and graphics cards of your consoles or gaming PCs. What matters for online gamers is low latency. Latency (defined as the average time it takes a network packet to travel from you, to a server, and back) is that lag you can sometimes see online, be it in a web page download stuttering or game struggling to keep up. An ISP needs to provide consistent and stable connection to the internet servers used for online play between players. One thing you can't always count on year to year is the gaming quality of a connection. The latency on ISPs can be up one year and down another, sometimes with startlingly different numbers.” https://www.pcmag.com/news/365904/the-best-gaming-isps-of-2019 https://www.pcmag.com/article/350064/the-best-gaming-isps-of-2017 6 ©2019 Extreme Networks, Inc. All rights reserved Esports: A Network Focus Cloud/ISP “A CDN is a network of strategically placed servers, each holding a copy of a website’s content. It’s able to address the factors influencing RTT in the following ways: • Points of Presence (PoPs) A CDN maintains a network of geographically dispersed PoPs—data centers, each containing cached copies of site content, which are responsible for communicating with site visitors in their vicinity. They reduce the distance a signal has to travel and the number of network hops needed to reach a server. • Web caching A CDN caches HTML, media, and even dynamically generated content on a PoP in a user’s geographical vicinity. In many cases, a user’s request can be addressed by a local PoP and does not need to travel to an origin server, thereby reducing RTT. • Load distribution During high traffic times, CDNs route requests through backup servers with lower network congestion, speeding up server response time and reducing RTT. • Scalability https://www.imperva.com/learn/performance/round-trip-time-rtt/ https://www.keycdn.com/blog/cdn-for-gaming A CDN service operates in the cloud, enabling high scalability and the ability to process a near limitless number of user requests. This eliminates the possibility of server side bottlenecks. • Tier 1 access CDNs have agreements with the biggest Internet Service Providers (ISPs) to provide Tier 1 access to the internet backbone. This reduces the number of network hops a connection must travel through, greatly reducing a signal’s round trip time.” 7 ©2019 Extreme Networks, Inc.
