| dc.description.abstract | 近年來，負載平衡常被使用於改善資料中心的整體效能或是資料流
的完成時間。然而當發生斷線的時候，會導致TCP 封包的遺失，這種
情況在TCP 的重傳機制下會導致資料流的完成時間遽增。其中進行負
載平衡的交換器若是不能及時偵測得知斷線的訊息，就會增加TCP 封
包的遺失數量。在本篇論文中，相比於傳統的鏈路狀態路由協定以及
集中式管理網路狀態的工具，我們提出一個建構在BFD 上的偵測演算
法讓交換器能及時得知斷線的發生。藉由模擬軟體OMNET++，我們
去評估我們的方法與定期偵測在效能上的差異。 | zh_TW |
| dc.description.abstract | Dynamic load balancing is a popular technique to improve overall throughput
or flow completion time in data center. Flow completion time represents
the time from a flow starting to transmit the first packet to the last packet
received. However, TCP retransmission protocol will incur longer flow completion
time when packet loss. And link failure is a common phenomenon
in data center. It will incur large packet loss if sender doing load balancing
is not able to timely acquire failure information of outgoing link. Compared
with recent link-state routing protocol and management tool, we propose an
algorithm based on BFD to enable network device doing load balancing to
timely know which outgoing path is unavailable. By simulation, we show
our technique can more fast detect the failure than pure periodical probing.
