Understanding Gaming Network Requirements

The Gaming Traffic Trinity

Gaming networks require three critical metrics:

1. Low Latency (Ping)

  • FPS games (CS:GO, Valorant): Under 30ms optimal, 50ms maximum
  • MOBA games (League of Legends, Dota 2): Under 60ms optimal, 100ms maximum
  • Fighting games: Under 20ms optimal, 40ms maximum
  • MMO games: Under 100ms acceptable, 150ms maximum

2. Minimal Jitter

  • Variation should not exceed 5ms
  • Consistent 50ms ping beats variable 20-80ms ping
  • Jitter causes rubber-banding and prediction errors

3. Zero Packet Loss

  • 0.1% packet loss creates noticeable gameplay issues
  • 1% packet loss makes competitive gaming impossible
  • Modern games do not handle packet loss gracefully

Gaming Traffic Patterns

Different game types generate different network patterns:

Game Type Bandwidth (Up/Down) Packet Size Frequency
FPS Games 30-100 Kbps 60-150 bytes 60-128 Hz
MOBA Games 20-50 Kbps 100-200 bytes 30-60 Hz
Cloud Gaming 15-50 Mbps 1400 bytes Continuous stream
Game Downloads Max available 1500 bytes Bulk transfer

Choosing the Right MikroTik Hardware for Gaming

Key Hardware Features for Gaming

Essential hardware considerations:

  • CPU Cores: Minimum dual-core for QoS processing
  • RAM: 256MB minimum, 1GB recommended for connection tracking
  • Switch Chip: Hardware switching reduces CPU load
  • FastPath Support: Critical for low-latency forwarding

Essential MikroTik QoS Configuration for Gaming

Basic QoS Setup Using Queue Trees

Queue trees provide better performance than simple queues for gaming. Configure the basic structure:

# Define your WAN interface and speeds
/queue tree
add name="Download" parent=global packet-mark=no-mark limit-at=90M max-limit=95M queue=default
add name="Upload" parent=global packet-mark=no-mark limit-at=18M max-limit=19M queue=default

# Create gaming priority queues
add name="Gaming-Download" parent=Download packet-mark=gaming-down limit-at=10M max-limit=95M priority=1 queue=sfq
add name="Gaming-Upload" parent=Upload packet-mark=gaming-up limit-at=5M max-limit=19M priority=1 queue=sfq

# Regular traffic queues
add name="Regular-Download" parent=Download packet-mark=regular-down limit-at=50M max-limit=85M priority=4 queue=sfq
add name="Regular-Upload" parent=Upload packet-mark=regular-up limit-at=10M max-limit=15M priority=4 queue=sfq

# Bulk traffic queues
add name="Bulk-Download" parent=Download packet-mark=bulk-down limit-at=10M max-limit=70M priority=8 queue=sfq
add name="Bulk-Upload" parent=Upload packet-mark=bulk-up limit-at=2M max-limit=10M priority=8 queue=sfq

Implementing CAKE Queue Type

CAKE (Common Applications Kept Enhanced) eliminates bufferbloat effectively:

# Enable CAKE queue type (RouterOS 7.x required)
/queue type
add name=cake-download kind=cake cake-bandwidth=95M cake-rtt=50ms cake-overhead=18 cake-nat=yes
add name=cake-upload kind=cake cake-bandwidth=19M cake-rtt=50ms cake-overhead=18 cake-nat=yes

# Apply CAKE to main queues
/queue simple
add name="WAN-Shaper" target=0.0.0.0/0 max-limit=19M/95M queue=cake-upload/cake-download

Traffic Marking for Gaming

Mark gaming traffic accurately using mangle rules:

# Mark gaming console traffic
/ip firewall mangle
add chain=forward src-address=192.168.1.50 action=mark-connection new-connection-mark=gaming-conn comment="PS5"
add chain=forward src-address=192.168.1.51 action=mark-connection new-connection-mark=gaming-conn comment="Xbox"

# Mark packets based on connections
add chain=forward connection-mark=gaming-conn in-interface=ether1 action=mark-packet new-packet-mark=gaming-down
add chain=forward connection-mark=gaming-conn out-interface=ether1 action=mark-packet new-packet-mark=gaming-up

# Mark by DSCP values (many games use EF - Expedited Forwarding)
add chain=forward dscp=46 action=mark-packet new-packet-mark=gaming-down in-interface=ether1
add chain=forward dscp=46 action=mark-packet new-packet-mark=gaming-up out-interface=ether1

# Mark common gaming ports
add chain=forward protocol=udp dst-port=3074,3478-3480,27015-27030 action=mark-connection new-connection-mark=gaming-conn
add chain=forward protocol=tcp dst-port=3074,27014-27050 action=mark-connection new-connection-mark=gaming-conn

Advanced MikroTik Gaming Optimizations

Game-Specific Port Configurations

Popular games use specific ports. Configure accordingly:

Valorant

/ip firewall mangle
add chain=forward protocol=udp dst-port=7000-8000,8180-8181 action=mark-connection new-connection-mark=valorant-conn
add chain=forward protocol=tcp dst-port=8393-8400 action=mark-connection new-connection-mark=valorant-conn

Call of Duty: Warzone

/ip firewall mangle
add chain=forward protocol=udp dst-port=3074,3075,3076,20000-20099 action=mark-connection new-connection-mark=cod-conn
add chain=forward protocol=tcp dst-port=3074,3075,3076 action=mark-connection new-connection-mark=cod-conn

Fortnite

/ip firewall mangle
add chain=forward protocol=udp dst-port=5795-5847,9000-9100 action=mark-connection new-connection-mark=fortnite-conn
add chain=forward protocol=tcp dst-port=5795-5847 action=mark-connection new-connection-mark=fortnite-conn

Dynamic Server Detection

Create address lists for game servers automatically:

# Detect and add game servers to address list
/ip firewall mangle
add chain=forward src-address=192.168.1.50 protocol=udp dst-port=!53,!123,!500,!4500 packet-size=60-200 \
    action=add-dst-to-address-list address-list=game-servers address-list-timeout=1h

# Mark traffic to detected game servers
add chain=forward dst-address-list=game-servers action=mark-connection new-connection-mark=gaming-conn
add chain=forward src-address-list=game-servers action=mark-connection new-connection-mark=gaming-conn

FastTrack Optimization

FastTrack bypasses CPU processing but conflicts with QoS. Use selectively:

# Disable FastTrack for gaming traffic
/ip firewall filter
add chain=forward action=fasttrack-connection connection-state=established,related \
    connection-mark=!gaming-conn connection-mark=!important-conn comment="FastTrack non-gaming"

# Accept all established connections
add chain=forward action=accept connection-state=established,related
