Performance Optimization Techniques for Krono Net X2

Checklist for Tuning Krono Net X2’s Network Performance

Quality of Service (QoS) Policies

• Traffic Classification and Prioritization
  Implement Differentiated Services Code Point (DSCP) marking to classify traffic into priority tiers (e.g., VoIP, video streaming, database transactions). Use the following DSCP values for common applications:

  VoIP (Real-Time): EF (46) – Expedited Forwarding

  Video Streaming (High Priority): AF41 (34)

  Database Transactions (Medium Priority): AF21 (18)

  Background Transfers (Low Priority): Default (0)

• Rate Limiting and Bandwidth Allocation
  Configure token bucket filters (TBF) or Hierarchical Token Bucket (HTB) to enforce bandwidth limits per traffic class. Example for a 100 Mbps link with 30 Mbps reserved for VoIP:

  tc qdisc add dev eth0 root handle 1: htb default 30
  tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit
  tc class add dev eth0 parent 1:1 classid 1:10 htb rate 30mbit prio 1
  tc class add dev eth0 parent 1:1 classid 1:20 htb rate 70mbit prio 2

• Congestion Avoidance
  Enable ECN (Explicit Congestion Notification) and set WRED (Weighted Random Early Detection) thresholds to drop packets before queues overflow. For a 1 Gbps interface with a target queue depth of 100 packets:

  tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10
  tc qdisc add dev eth0 parent 1:10 classid 1:10 handle 10:1 sfq limit 100
  tc qdisc add dev eth0 parent 1:10 classid 1:10 handle 10:1 wred minth 100 maxth 150

• Dynamic Buffer Sizing
  Adjust the RX/TX ring buffer sizes based on packet size and throughput. For high-speed interfaces (e.g., 10 Gbps), use the following guidelines:

  RX Buffer (Packets): 2048–4096 (for jumbo frames, increase to 8192)

  TX Buffer (Packets): 1024–2048

  RX/TX Thresholds: 64–128 bytes (adjust for small packets)

  Apply via kernel module parameters (e.g., `ethtool -G eth0 rx 4096 tx 2048`).
• Zero-Copy and Kernel Bypass
  Enable DPDK (Data Plane Development Kit) or XDP (eXpress Data Path) for latency-sensitive workloads. For DPDK, bind NICs to dedicated CPU cores:

  dpdk-devbind.py --bind=vfio-pci 

• Packet Steering
  Use RSS (Receive Side Scaling) to distribute traffic across multiple CPU cores. Configure via `ethtool`:

  ethtool -L eth0 rx 4 combined 4

• Multi-Chassis Link Aggregation (LACP)
  Configure LACP for failover and load distribution across bonded interfaces. Example for a 4-port aggregation:

  ip link add bond0 type bond mode 4 miimon 100
  ip link set eth0 master bond0
  ip link set eth1 master bond0
  ip link set bond0 up

• Global Load Balancing (GLBP)
  Deploy GLBP in routing environments to distribute traffic across multiple gateways. Example for a 3-gateway setup:

  router eigrp 100
  variance 2
  maximum-paths 3

• Geographic Load Balancing
  Use Anycast routing or BGP-based load balancing for distributed applications. Configure BGP next-hop attributes:

  neighbor 192.0.2.1 next-hop-self
  neighbor 192.0.2.1 route-map ANYCAST out

Monitoring Krono Net X2’s Resource Usage

Built-in Tools

• CPU and Memory Utilization
  Use `sar` (System Activity Reporter) to track CPU load and memory pressure. Example for 5-minute intervals:

  sar -u 5 60  # CPU usage (5-sec intervals, 60 samples)
  sar -r 5 60    # Memory usage (resident set size)

  Key metrics:

  CPU (User/Kernel): >70% sustained indicates saturation.

  Memory (Active/Inactive): Inactive >50% of RAM suggests over-provisioning.

• Network Interface Statistics
  Monitor interface-specific metrics with `iftop` or `nload`:

  iftop -n -i eth0  # Real-time bandwidth per connection
  nload eth0          # Graphical bandwidth/delay view

  Critical thresholds:

  Packet Loss: >0.1% sustained on high-speed links.

  Latency (RTT): >50 ms for latency-sensitive traffic.

• Disk I/O Bottlenecks
  Analyze disk latency with `iostat` or `iotop`:

  iostat -x 2  # Extended disk stats (2-sec intervals)
  iotop -o        # Identify high-I/O processes

  Warning signs:

  Avgqu-Sz: >2 indicates queueing delays.

  %util: >90% sustained on SSDs/HDDs.

• Prometheus and Grafana
  Deploy the `node_exporter` to collect Krono Net X2 metrics (e.g., `net_device_stats`, `system_cpu`). Example PromQL query for interface errors:

  sum(rate(net_device_stats_rx_errors_total[5m])) by (device)
