NERD: Network-Flow Editor

Editing living data streams that exist as active network circulation patterns

Revolutionary Concept

NERD is a revolutionary editor that operates on files that exist as living network processes. These aren't stored files that happen to be distributed - they're active, flowing patterns of data circulation that exist in the movement of network traffic itself. The file IS the network activity.

Core Paradigm Shift

Traditional Model: File → Storage → Network Transport → Edit → Store Back
NERD Model: File IS Network Flow → Edit the Flow Pattern Directly

Files exist as:

• Self-sustaining circulation loops in network traffic
• Dynamic routing patterns that carry data
• Living processes made of connection flows
• Patterns that exist in the movement itself, not in static storage

Technical Architecture

Level 1: Raw Network Interface

• Raw socket programming for packet-level manipulation
• Custom packet formats for flow identification
• Real-time packet injection and modification
• Network interface manipulation

Level 2: Flow Pattern Management

• Circulation pattern definition and maintenance
• Self-sustaining traffic loops
• Network topology awareness and adaptation
• Flow discovery and coordination

Level 3: Ed-Compatible Interface

• Traditional text editing commands
• Real-time flow modification
• Network-aware file operations
• Multi-user editing support

Building NERD

Prerequisites

• C++17 compatible compiler (GCC 7+, Clang 5+)

Usage Examples

Basic Flow Editing

$ sudo ./nerd myflow
NERD: Network-Flow Editor
Editing living data streams that exist as active network circulation patterns

> append Hello, this is a living network file!
> append It exists as circulating packets in the network.
> print all
1	Hello, this is a living network file!
2	It exists as circulating packets in the network.
> write
Flow written to circulation pattern
> quit

Flow Discovery

> discover
Discovering existing flows in network...
Found flows: document1, logfile, config
> open document1
Opened flow: document1
> print all
1	This document exists as network circulation
2	Multiple editors can modify it simultaneously
3	No traditional storage - pure network motion

Multi-User Editing

# User A
$ sudo ./nerd shared_doc
> append User A's contribution

# User B (on different machine)
$ sudo ./nerd shared_doc
> append User B's contribution
> print all
1	User A's contribution
2	User B's contribution

Core Components

NetworkFlow

Manages active streams and circulation patterns:

class NetworkFlow {
    void inject_packet(const RawPacket& packet);
    void modify_flow_pattern(FlowID id, const CirculationPattern& pattern);
    void sustain_circulation();
};

FlowFile

Represents a file as a living network process:

class FlowFile {
    void maintain_flow();
    void modify_pattern(const EditCommand& cmd);
    std::string read_from_flow();
    void write_to_flow(const std::string& data);
};

FlowManager

Coordinates multiple active files and network topology:

class FlowManager {
    FlowFile* open_flow(const std::string& flow_name);
    void create_circulation_pattern(const std::string& name);
    void sustain_all_flows();
};

FlowEditor

Provides ed-compatible interface:

class FlowEditor {
    void append_to_flow(const std::string& line);
    void delete_from_flow(int start, int end);
    void substitute_in_flow(const std::string& pattern, const std::string& replacement);
};

Technical Challenges Solved

1. Flow Sustainability

• Problem: How to create network traffic patterns that sustain themselves?
• Solution: Heartbeat packets and circulation pattern maintenance
• Implementation: Automatic packet regeneration and timestamp updates

2. Data Encoding

• Problem: How is file content encoded in circulation patterns?
• Solution: Packet-based content distribution with sequence ordering
• Implementation: Content serialization across multiple packets with flow identification

3. Flow Discovery

• Problem: How do you find and connect to existing flows?
• Solution: Broadcast discovery packets and flow registry
• Implementation: Network-wide flow announcement and response system

4. Edit Propagation

• Problem: How do edits propagate through the circulation pattern?
• Solution: Edit command packets that modify flow patterns in real-time
• Implementation: Immediate packet injection and pattern modification

5. Network Efficiency

• Problem: How to avoid creating network storms or congestion?
• Solution: Rate limiting and intelligent circulation patterns
• Implementation: Configurable circulation rates and packet age management

Network Protocol

Packet Format

[Ethernet Header] [Flow Header] [Payload]

Flow Header

struct FlowPacketHeader {
    uint32_t magic;           // "NERD" magic number
    FlowID flow_id;           // Unique flow identifier
    uint32_t sequence;        // Sequence number within flow
    uint32_t packet_type;     // Data, Control, Heartbeat, Edit, Discovery
    uint32_t data_length;     // Payload length
    uint64_t timestamp;       // Flow timing
};

Packet Types

• FLOW_DATA: File content packets
• FLOW_CONTROL: Flow management commands
• FLOW_HEARTBEAT: Circulation maintenance
• FLOW_EDIT: Edit command propagation
• FLOW_DISCOVERY: Flow discovery and registration

Success Criteria

• ✅ nerd myflow connects to a living data circulation pattern
• ✅ Edits modify the flow pattern in real-time
• ✅ Files survive as long as the circulation pattern is maintained
• ✅ Multiple editors can modify the same flow simultaneously
• ✅ Network disruptions cause flow adaptation, not file loss
• ✅ No traditional storage - the file exists purely in network motion

Revolutionary Insight

This isn't networked storage or distributed files - it's computational network traffic. Files as living processes that exist in the movement of data itself. You're editing the flow patterns of active network circulation, not stored data.

The question isn't "where is the file stored?" but "how is the file circulating?"
