Broadband Access Network

There are many factors that can affect network performance, such as delay, packet loss and capacity utilization. A Wireless-Optical Broadband Access Network (WOBAN) is gaining more attention because its good performance and merits such as reliability, robustness and high capacity as well as flexibility. In this paper, we proposed the Flow Limited and Risk Aware Routing Algorithm (FLRAR), which takes capacity utilization and link failure into account. And we also used Link Success Rate (LSR) to detect the link failure and redirect the related packets. The research results show that the process of information fusion has abilities of adapting and self-learning.

Broadband Access Network

Cloud-integrated wireless optical broadband (CIW) access networks inheriting advantages of cloud computing, wireless and optical access networks have a broad prospect in the future. Due to failure of components like OLT level, ONU level, link or path failure and cloud component level in CIW, survivability is becoming one of the important issues. In this paper, we have presented cloud-integrated wireless-optical broadband access network with survivability using integer linear programming (ILP) model, to minimize the number of cloud components while providing maximum backup paths. Hence, we have proposed protection through cloud-integrated wireless router to available ONUs (PCIWRAO). So, evaluated the backup path computation. We have considered ONU level failure in which the affected traffic is transferred through wireless routers and cloud component to the available ONUs using Manhattan distance algorithm. Simulation results show different configurations for different number of routers and cloud components illustrating available backup path when ONU fails.
