路径管理

MPTCP:

1. “default”: This path manager actually does not do anything. It will neither announce different IP addresses nor initiate the creation of new subflows. However, it will accept the passive creation of new subflows.
   这个路径管理器实际上什么也不做。它既不会宣布不同的IP地址，也不会启动新的子流的创建。但是，它将接受新子流的被动创建

2. “fullmesh”: As the name already says, this path manager establishes the full mesh [16] of subflows.
   建立全部的子流网格状

3. “ndiffports”: Instead of using multiple IP addresses, this path manager always uses the same IP-address pair for its paths. However, each path uses different source and destination TCP ports. This path manager is intended to circumvent bandwidth-limiting middleboxes by mimicking different TCP connections.

4. “binder”: This path manager [23] is using Loose Source Routing [24] to distribute the packets of subflows. Using packet relays, it allows for applications on enduser devices to benefit from gateway aggregation without requiring any modifications.
