Description

一种多路径传输的方法及设备

技术领域
本发明涉及通信技术领域，尤其涉及一种多路径传输的方法及设备。
背景技术
目前，随着互联网的飞速发展，以及手机、笔记本等用户设备(User Equipment，UE)宽带接入技术的进步，一个用户设备具有多个网络接口，如Wi-Fi(Wireless-Fidelity，无线保真)接口、2G(The 2nd Generation Mobile Communication Technology，第二代移动通信技术)接口、3G(The 3rd Generation Mobile Communication Technology，第三代移动通信技术)接口、4G(The 4th Generation Mobile Communication Technology，第四代移动通信技术)接口、5G(The 5th Generation Mobile Communication Technology，第五代移动通信技术)接口等等，从而可以实现到目标节点的多条链路。传统的传输控制协议(Transfer Control Protocol，TCP)是一对一的传输协议，不能够充分利用用户设备的多址多网络接口的优势，从而造成资源浪费。基于此，IETF(Internet Engineering Task Force，互联网工程任务组)提出了MPTCP(MultiPath TCP，多路径传输控制协议)。MPTCP是一种TCP的改进协议，它允许通信双方同时通过多条连接进行数据传送。目前常见的多路协议部署方法有：将多路协议部署在服务器，在服务器做多路传输，可以保证在蜂窝网络和Wi-Fi网络下都能流畅数据；将多路协议部署在网络设备节点，将长期演进(long term evolution,LTE)与Wi-Fi网络相结合，提升带宽和网速。但目前的多路协议部署方法需要设备厂商或者运营商在服务器或者基站部署多路协议，带来很高的成本。

本申请实施例公开了一种多路径传输的方法及设备，用于解决目前部署多路径传输协议成本高的问题，且可以降低通信的时延。利用路由器与移动终端协同使用多路径传输协议，能够不依赖第三方服务器，解决在公共场所访问网络有安全风险的问题。将多路径传输协议部署在本地路由器相比部署在服务器或者网络设备的节点更加节省成本。以下将分别进行详细说明。
本申请提供一实施例，如图1所示，多路径传输协议位于网络协议栈的传输层。网络协议栈(protocol stack)，又称为协议堆叠，是计算机网络协议套件的一个具体的软件实现。网络协议栈分为应用层、传输层、网络层、数据链路层、物理层，多路径传输协议属于传输层的协议。部署了多路径传输协议的发送端允许在一条传输控制协议(transmission control protocol,TCP)链路中建立多个子通道，当一条通道按照TCP协议的三次握手的方式建立起来后，可以按照三次握手的方式建立其他子通道。这些通道以三次握手建立连接和四次握手解除连接。上述通道都会绑定多路径传输的会话(session)，上层的应用(application)可以在建立的多条通道中选择其中一条进行传输。多路径传输协议的第一个子通道的建立，遵循TCP的三次握手，并在每次发送的报文段添加能够建立多路径传输的标识符，如“MP_CAPABLE”，和一个安全用途的key。在建立其他子通道时， 需要进行三次握手，在每次发送报文段将能够建立多路径传输的标识符更换为加入多路径传输的标识符，如“MP_JOIN”，并基于key值生成一个token，用以标识该子通道。多路径传输协议把需要发送的数据分割成多份，并用上述建立的子通道进行传输，每一个子通道都是一个单独的端对端回话。在部署了多路径传输协议的接收端，可以把上述接收的数据聚合成单一的数据。这种传输机制对于上层应用程序来说是不透明的。上层应用程序可以通过应用程序接口(application programming interface,API)在链路池中添加和删除地址，但不能直接管理和操作多路径传输协议的数据通道。多路径传输协议保证了低层级的TCP组件不受影响。
多路径传输协议在链路中建立子通道的具体流程为：发送端会向接收端发送SYN消息，在多路径传输协议的字段中包含了能够建立子通道的标识符。如果接收端也支持相同的多路径传输协议，会返回SYN+ACK响应，在同样的字段中包含了能够建立子通道的标识符。发送端与接收端的会话使用ACK和能够建立子通道的标识符完成了握手过程，确保两端都得到了对方的会话数据。在整个会话过程中，两端交换了64位字节的会话密钥，同时各自生成一个32位的哈希共享密钥。示例性地，移动终端同时使用无线保真(wireless fidelity,Wi-Fi)网络和4G蜂窝网络与服务器建立多路径传输对话。移动终端使用4G蜂窝网络发送一个SYN数据包给服务器，上述SYN数据包携带了MP_CAPABLE字段，表明移动终端支持多路径传输协议，以及一个key；服务器的回应SYN+ACK数据包同样携带了MP_CAPABLE字段以及一个key；移动终端再次回应ACK，此时建立移动终端与服务器之间的数据通道；移动终端使用Wi-Fi网络发送SYN数据包，上述SYN数据包携带了MP_JOIN字段，说明移动终端要建立子通道，并且携带一个token，上述token为上述key的哈希值，上述SYN数据包还携带了rand字段，rand是一个随机数；服务器回应的SYN+ACK数据包携带了rand字段和HMAC字段，HMAC是rand的哈希值；移动终端再回复ACK数据包，携带HMAC字段；服务器回复ACK数据包，此时移动终端与服务器的四次握手完毕，建立子通道连接。
可以理解的是，在发送端运行多路径传输协议时，会产生协同信息，该协同信息用于与接收端协商建立多路数据传输通道；发送端将上述协同信息发送至接收端，接收端将协同信息接收；接收端运行多路径传输协议，将其接收的协同信息进行识别，如果识别成功，则向发送端发送匹配信息；发送端接收上述匹配信息，并根据匹配信息进行匹配，如果匹配成功，则发送确认匹配信息给接收端；接收端在收到确认匹配信息后，建立多路数据传输通道。
发送端使用多路径传输协议传输数据时，采用的模式为：(1)多路冗余多发，即发送端根据多路径传输协议把需要传输的同一数据包进行复制，然后通过多条数据通道并行发送至接收端，接收端会根据不同的数据通道发送来的数据包的序号进行数据包聚合，如果有来自不同数据通道的相同序号的数据包，则将留下一个数据包并将剩余的相同数据包丢弃，如果序号不同，则将不同序号的数据包进 行聚合；(2)丢包补包，即当发送端识别到数据包发送失败，需要通过多路径传输协议增加一条子通道，把上述数据包丢失的数据进行补充发送，接收端收到发送端补充发送的数据包，并将补充发送的数据包与初始发送的数据包进行聚合；(3)特殊报文冗余多发，发送端将关键的报文进行复制，在数据包被以上述(1)、(2)两种方式发送的情况下，发送端再通过多路径传输协议建立的子数据通道进行补充发送，该补充发送的数据包与上述以(1)、(2)方式发送的数据包并行发送到接收端，接收端会根据不同的数据通道发来的数据包的序号进行数据包聚合，如果有来自不同数据通道的相同序号的数据包，则将留下一个数据包并将剩余的相同数据包丢弃，如果序号不同，则将不同序号的数据包进行聚合。
多路径传输协议使用四次握手是为了保证连接的安全，并且可以提供可靠的传输。使用多路径传输协议可以避免断线重连，充分利用网络资源，例如即使没有Wi-Fi连接，也可以通过蜂窝网络继续进行数据传输。
