内容梗概 (abstract) Current distributed systems require a large and increasing amount of network resources and greatly benefit from a larger bandwidth.
Network environments, such as in data centers and across wide-area networks, usually provide multiple paths for each host to mitigate possible network failures.
However, even with multiple paths to utilize, only one path is used per connection, which severely limits the maximum throughput.
Additionally, there is no comprehensive multipathing solution as of the start of this research.
Even by using transport-layer multipathing protocol such as MPTCP, it is still incomplete because this protocol is not in control of network routing.
By providing a multipathing-aware routing system it is possible to increase useable bandwidth between two hosts and provide a more stable connection,
both of which are crucial requirements of many distributed systems.

There are previous work that has been conducted on routing in high-performance networks like this, but so far they are mostly concerned about creating
general-purpose bandwidth maximization algorithms in routing, without concern about optimizing for specific cases such as MPTCP and software-defined networks.
On the other side, recent research on ``multipath routing concerns more about wireless and ad hoc communications, which are not the case for data center networks or wide-area networks.
By thoroughly studying and carefully combining multipath routing theories and software-defined network, it is possible to improve the performance of distributed systems.

In this dissertation, a better routing algorithm that is tailored for MPTCP is explored, along with other similar algorithms that
promise similar qualities. It is expected that this algorithm will, in terms of total throughput between a single pair of hosts, perform as well as
simple shortest-path algorithms under the conditions of a spanning-tree network, or general networks without the use of MPTCP, while performing better when
both multiple paths and MPTCP are available. This work is expected to result in a better performance for distributed systems, and outlines the possible
ways to increase available throughput and increase the performance.
