-- Example of robust connection handling
local function handlePlayerConnection(source)
    local success, error = pcall(function()
        -- Validate connection
        if not source then return false end
        
        -- Check player state
        local playerState = GetPlayerState(source)
        if not playerState then return false end
        
        -- Initialize player data
        local success = InitializePlayerData(source)
        if not success then

            return false
        end
        
        return true
    end)
    
    if not success then
        print('Connection handling failed:', error)
        return false
    end
    return true
end
 
-- Example of connection monitoring
local function monitorConnection(source)
    local lastPing = GetPlayerPing(source)
    if lastPing > 200 then  -- 200ms threshold
        print('Warning: High ping for player', source, ':', lastPing, 'ms')
    end
end

-- Example of network optimization
local function sendOptimizedData(source, data)
    -- Compress data if large
    if #data > 1000 then
        data = CompressData(data)
    end

    local chunks = SplitIntoChunks(data, 1000)
    
    -- Send chunks with delay
    for i, chunk in ipairs(chunks) do
        TriggerClientEvent('receiveData', source, chunk, i, #chunks)
        Wait(10)  -- Small delay between chunks
    end
end
 
-- Example of rate-limited updates
local lastUpdate = {}
local function rateLimitedUpdate(source, data)
    local currentTime = GetGameTimer()
    if not lastUpdate[source] or currentTime - lastUpdate[source] > 100 then
        lastUpdate[source] = currentTime
        TriggerClientEvent('updateData', source, data)
    end
end

-- Example of error recovery
local function handleNetworkError(source, error)
    print('Network error for player', source, ':', error)
    
    -- Attempt recovery
    local success = ReconnectPlayer(source)
    if not success then
        -- If recovery fails, handle gracefully
        print('Failed to recover player connection')
        DropPlayer(source, 'Network error. Please reconnect.')
    end
end
 
-- Example of data validation
local function validateNetworkData(data)
    if type(data) ~= 'table' then
        return false, 'Invalid data type'
    end
    
    -- Validate required fields
    if not data.requiredField then
        return false, 'Missing required field'
    end
    
    -- Validate data size
    local json = json.encode(data)
    if #json > 16000 then
        return false, 'Data too large'
    end
    
    return true
end

-- Add performance monitoring to network operations
local function monitoredNetworkOperation(source, data)
    local startTime = GetGameTimer()
    
    -- Your network operation code here
    
    local endTime = GetGameTimer()
    local duration = endTime - startTime
    
    if duration > 10 then  -- 10ms threshold
        print('Warning: Network operation took', duration, 'ms')
    end
end
 
-- Example of bandwidth monitoring
local bandwidthUsage = {}
local function monitorBandwidth(source, dataSize)
    bandwidthUsage[source] = (bandwidthUsage[source] or 0) + dataSize
    if bandwidthUsage[source] > 1000000 then  -- 1MB threshold
        print('Warning: High bandwidth usage for player', source)
    end
