With the rapid development of converged network technology, the network shows an obvious trend to be heterogeneous. In order to solve this problem, this paper proposes a multi-controller collaborative interconnection architecture for multilayer heterogeneous SDON (Software Defined Optical Network). And to enable this architecture, OpenFlow protocol is extended accordingly. Furthermore, the inter-domain...
This paper proposes a cross-layer collaborative interconnecting approach for the multi-control domain SDON networks. It's able to optimize network resources and achieve the real-time response of the network state. We use this approach to handle the traffic in single control domain and multi-control domain, which optimize transmission of the large granular traffic and the small granular traffic in...
The flat architecture becomes the evolution direction of the next generation Mobile Communication Network. It can also lighten the load on the core network effectively. The LIPA (Local IP Access) and SIPTO (Selected IP Traffic Offload) proposed by 3GPP are the typical technologies to implement the flat traffic offload in the user side. Current offload mechanisms for LIPA/SIPTO are either costly for...
With the development of Mobile Communication Network, flat network architecture has become a study focus. The flat traffic transmission can effectively lighten the burden on the operators' core network. The LIPA (Local IP Access) and SIPTO (Selected IP Traffic Offload) proposed by 3GPP are the typical technologies in the horizontal structure evolution. Current offload policy for LIPA&SIPTO either...
In order to improve the customer's QoS satisfaction, a method and a system for fast positioning SLA violations are designed in this paper. First, a kind of database called SLA violation experience database and a system for fast positioning SLA violations are brought forward. Then, a tree called SLA violation experience tree is built based on the Huffman. Finally, the system is tested by some examples...
