Handling traffic dynamics in order to avoid
network congestion and subsequent service disruptions is one of the key tasks
performed by contemporary network management systems. Given the simple but
rigid routing and forwarding functionalities in IP base environments, efficient
resource management and control solutions against dynamic traffic conditions is
still yet to be obtained. In this article, we introduce AMPLE - an efficient
traffic engineering and management system that performs adaptive traffic
control by using multiple virtualized routing topologies. The proposed system
consists of two complementary components: offline link weight optimization that
takes as input the physical network topology and tries to produce maximum
routing path diversity across multiple virtual routing topologies for long term
operation through the optimized setting of link weights. Based on these diverse
paths, adaptive traffic control performs intelligent traffic splitting across
individual routing topologies in reaction to the monitored network dynamics at
short timescale. According to our evaluation with real network topologies and
traffic traces, the proposed system is able to cope almost optimally with
unpredicted traffic dynamics and, as such, it constitutes a new proposal for
achieving better quality of service and overall network performance in IP
networks.
