WebRTC DataChannel缓冲已满

Question

起初，我希望你明白我不擅长英语。

对于文件传输，在网格拓扑中，在Chrome中，

当缓冲量为16MB时，通道将关闭并显示错误消息。

“未捕获的网络错误：无法在'RTCDataChannel'上执行'发送'：无法发送数据”
（它是chrome，而不是firefox。）

如何发送文件（超过16MB）？

fileWorker.js

var chunkSize = 16384;
onmessage = function(event) {
    var file = event.data[0],
        callbackId = event.data[1],
        totalSize = file.size,
        chunks = [],
        curSize = 0,
        reader,
        chunk;

    if (!FileReaderSync) {
        reader = new FileReader();
        reader.onload = function(event) {
            console.log('chunking...');
            chunks.push(event.target.result);
            curSize += chunkSize;
            slice();
        };
        slice();
    } else {
        reader = new FileReaderSync();
        while (curSize < totalSize) {
            console.log('chunking...');
            chunk = file.slice(curSize, curSize + chunkSize);
            chunks.push(reader.readAsArrayBuffer(chunk));
            curSize += chunkSize;
        }
        postMessage([chunks, file.name, callbackId]);
    }

    function slice() {
        if (curSize > totalSize) {
            postMessage([chunks, file.name, callbackId]);
        } else {
            chunk = file.slice(curSize, curSize + chunkSize);
            reader.readAsArrayBuffer(chunk);
        }
    }
};

fileSender

_fileToPeers: function(chunks, fileName, progressCallbackId) {
    var callback = callbacks[progressCallbackId],
        chunkCount,
        peerCount = 0;

    objForEach(this.peers, function(peer) {
        var channel = peer.fileChannel;
        peerCount += 1;

        if (channel) {
            chunkCount = 0;
            chunks.forEach(function(chunk) {
                channel.send(chunk);
                chunkCount += 1;
                console.log('sending...');         // abnormal works!  
                callback(peerCount, chunkCount);   // abnormal works!
            });
            channel.send(['end', fileName].join(','));
        }
    });
    delete callbacks[progressCallbackId];
},
