#### A.2.2.2.1 Introduction

The current architecture provides three network characteristics:

- Latency: Configured per segment, aggregated additively;

- Jitter: Standard deviation of RTT measurements;

- Throughput: Modulated based on distance from POA (5 concentric steps);

- Packet Loss: Configured per segment, aggregated using cumulative formula.

These network characteristics are calculated and applied at different stages:

1. Configuration Stage: Characteristics are configured per network segment (POA, Zone, Domain)

2. Application Stage: Characteristics are applied using Linux Traffic Control [\[i.2\]](#_ref_i.2),

3. Measurement Stage: Actual characteristics are measured from network traffic

4. Aggregation Stage: Characteristics are aggregated along network paths

1. Application Stage: Characteristics are applied using Linux Traffic Control [\[i.2\]](#_ref_i.2),

1. Measurement Stage: Actual characteristics are measured from network traffic

1. Aggregation Stage: Characteristics are aggregated along network paths

Too reflect the Signal Strength calculation in the UE network traffic, the current architecture uses a Linux tool name `tc netem` [\[i.2\]](#_ref_i.2). Several components are involved in the simulation:

- The TC Engine (`go-apps/meep-tc-engine/`): To calculates network characteristics per flow;

- The TC Sidecar (`go-apps/meep-tc-sidecar/`): To applies `tc netem` [\[i.2\]](#_ref_i.2) rules to pod network interfaces;

- The Network Characteristic Manager (`go-packages/meep-net-char-mgr/`): To aggregates network characteristics along network paths

tc qdisc change dev ifb<id> root netem delay <latency>ms <jitter>ms loss <packetLoss>% rate <throughput>bit

```

This command requires:

- The network interface (ifb);

- The calculated latency;

- The calculated throughput;

##### A.2.2.2.2 Latency calculation

The latency is set in the scenario configuration files (netChar.latency in milliseconds). It is applied to:

- Domain level;

- Zone level;

- Network Location (POA) level;
