A Collection Of Actual Measurement And Optimization Techniques On The Impact Of The Simulator's Japanese Native Ip On Game Latency

with the popularity of cross-border mobile games and console games, many players use japanese native ips in emulators to connect to japanese game servers in order to reduce latency and improve stability. however, the actual effect is greatly affected by the network path, nat, the emulator itself, and the quality of the transit service.

actual measurement part: on the same pc, when directly accessing japanese game servers using domestic public network ip, the typical delay is between 120~180ms; relaying through low-quality overseas vpn may increase the delay to more than 200ms. through the data center vps in japan or the dedicated line exit of the japanese computer room, the delay can often be stabilized at 40~80ms, and the jitter and packet loss rate are significantly reduced.

analysis of influencing factors: first, routing and bandwidth, the hop count and congestion of intermediate links directly determine rtt; second, the network stack overhead of the simulator, some simulators use nat by default, which adds additional forwarding delays; third, improper dns resolution and domain name proximity policies will direct traffic to non-optimal nodes.

optimization suggestion one: rent a vps or server in a japanese computer room and configure it as a transit node. compared with ordinary vpns, self-built vps can provide more stable exit ip and shorter routes. it is recommended to choose a plan with bgp direct connection and guaranteed bandwidth. check the bandwidth and traffic charges clearly when purchasing, and give priority to solutions that support ipv4/ipv6.

optimization suggestion two: use the nearest cdn or game acceleration node. cdn can cache static resources and reduce first packet delay; for real-time games, choosing a cdn that provides udp/quic acceleration and anycast lines can significantly reduce jitter. at the same time, combined with geodns, players can automatically resolve to the nearest acceleration point.

optimization suggestion three: domain name and dns optimization. configure the game domain name to be resolved in multiple locations and use high-performance resolution services to shorten dns resolution time; enable dns prefetching and local dns caching when conditions permit to avoid additional waiting caused by resolution.

optimization suggestion four: anti-ddos and high-defense solutions. game servers that are online for a long time will become targets of attacks. choosing a computer room or cdn with high anti-ddos capabilities can ensure node availability during traffic attacks. it is recommended to purchase high-defense products that include cleaning capabilities and elastic bandwidth to prevent the gaming experience from being interrupted by attacks.

optimization suggestion five: simulator and host settings. prioritize the use of simulators with bridge mode and udp direct connection, and turn off unnecessary plug-ins and intermediate proxies. try to use wired connections for local networks. adjusting the system tcp congestion algorithm, mtu, and keepalive parameters can further reduce packet loss and retransmission.

deployment strategy and purchase suggestions: for players or small game platforms who want to stably connect to japanese servers, it is recommended to first purchase a japanese vps as an export node, and then combine it with anycast cdn and high-defense strategies to form a multi-layer protection and acceleration system. when purchasing, it is recommended to choose a service provider that supports quick work orders and local bandwidth monitoring to facilitate optimization and expansion.

if you need stable japanese computer rooms, vps and high-defense ddos services, we recommend dexun telecom. dexun telecom provides a variety of japanese node vps, computer room rental, domain name resolution and cdn acceleration solutions, and supports high-defense annual purchase. it is suitable for game projects or individual players that require long-term low latency and high availability. purchase inquiries are welcome.
