| The new network architecture C-RAN( Centralized, Cooperative, Cloud Radio Access Network) is based on centralized baseband pool, with the remote radio frequency unit and antenna collaborative Wi-Fi and cloud-based real-time basis based on open network architecture platform. while the virtual resource pool program has a significant advantage, there are some technical difficulties need to be resolved: When these processing units has concentrated in the baseband pool, due to the network size increase sharply, how to design an efficient collaborative open platform combinations and distribution of the resource has become the key point; Meanwhile, it is necessary to consider how to design a dynamic network protocol processing unit with the corresponding processing platform and infrastructure to accommodate the requirements for efficient processing of large-scale network load, and enhance the resource utilization.Depend on the difficulties of virtual resource pool technical programs, based on the traffic engineering, we hope to design a architecture protocol options fully adapted to the new network. There are two aspects of processing elements:1) Using Equal Cost Multipath Protocol to provide more efficient routing choice for data flow.2) through the Resource Reservation Protocol to provide quality assurance for communications services.For routing algorithm based on traffic engineering, its optimization strategy is mainly to reduce competition between the paths, when there is remaining resources on other optional path, the path has been selected on the network resources are not overused, making the link flow tends to balance, to avoid excessive overload condition occurs. Therefore, this paper improve the traditional ECMP agreement, effective use of multi-equivalent resource pool link structural characteristics to achieve load balancing for each path in the network topology, dynamic ECMP algorithm is proposed based on the average link utilization, effectively raising the throughput and transmission efficiency of the network.Efficient routing protocol can improve the efficiency of service delivery, service quality assurance services has also need the appropriate protocol. Based on the resource-oriented target traffic engineering, quality assurance verification RSVP to communicate real-time applications, and existing mechanisms for Best-effort combined together to complete the large-scale structure in the network resource pools service quality assurance. Achieve each intermediate node(routers) to complete the path and resource reservation, solve different path with a stream of packets to avoid the path leading to congestion and packet loss to ensure low latency network requirements.The two protocol cooperate with each other to deal with the data streams of resource pools, ensure the quality of transport services and improve the efficiency of transmission. |
