Abstract:
The traditional single path routing can cause
imbalanced link utilization and is not efficient for all
traffic types such as long-lived large flows.
Moreover, it can lead to low network throughput and
high network latency. Traffic engineering (TE) is a
key solution to solve these problems of single path.
The main purpose of TE is to optimize the network
resource utilization and improve network
performance by measuring and controlling network
traffic. One of the TE approach for large flows is
multipath routing which distribute traffic load among
available multiple paths. To be intelligent multipath
routing based on traffic types, we also need to detect
large flow in network. In this paper, we present two
main folds: (1) large flow detection approach by
using sFlow analyzer in real time, and (2) measuring
end-to-end delays of available paths between source
node and destination node where large flow occurred
in SDN environment.
