Analysis And Application Of BGP Technology On ISP

The demand and application of mobile ad-hoc networks have been increasing step by step,with the rise of cloud computing,large data and mobile Internet.Mobile ad-hoc networks provide data access and data exchange anywhere and anytime.The amount of data access and the amount of data exchange increase with the number of users,which make the size and complexity of the Internet further expand.Users could access Internet mainly depending on Internet access services provided by different ISPs.The ISPs are interconnected through the BGP.BGP has become the most basic routing protocol which is widely used in cloud computing and mobile ad-hoc networks.Further research and development of the BGP can continuously improve the stability and efficiency of the network,in order to ensure the user's demand for network applications.A new overall launch architecture is proposed to reduce the difficulty of designing launch architecture.At the same time,the ISP network design principles are proposed to build a stable and scalable network.This paper presents a new migration method of network architecture。The migration process is discussed in detail taking migrating from i BGP fully-connected network architecture to coalition-based network architecture as an example.The network architecture migration method proposed in this paper has shorter network interruption time and less traffic loss than the existing migration methods.In the application of BGP to ad hoc networks,this paper presents a maximum-reliability multi-path routing algorithm.Compared with the traditional multi-path routing algorithm,the multi-path algorithm proposed in this paper has a good effect in the concurrent transmission of traffic,improving the effect of bandwidth aggregation,successful message transmission,improving throughput and load balancing.The maximum reliability routing algorithm proposed in this paper is of great significance to further improve the network performance.The final verification has a conclude,that is,the proposed multipath routing algorithm has a good effect on concurrent transmission traffic,less frequent path discovery,significantly reduced path overhead,more aggregate bandwidth and better load balancing.Therefore,the maximum reliability multipath routing algorithm proposed in this paper is of great significance to further improve network performance.The main work of this paper includes the following aspects:(1)This paper firstly analyzes the research status of BGP protocol at home and abroad and the background of this thesis.(2)This paper discusses ISP and BGP architecture from the aspects of the composition of the ISP,the working principle of BGP,BGP message and neighbor connection status.(3)This paper analyzes the basic path attributes and routing selection of BGP in detail.First of all,taking the topology between two ISPs as an example,the routing selection process is illustrated in detail.Then,the method of enhancing the extensibility of Internal Border Gateway Protocol is presented,that is,the routing reflection and the alliance.Aiming at the routing reflection,a new overall launch architecture is proposed.Based on the comparison between the routing reflection and the alliance,it provides a theoretical basis for practical selection.At last,the network design principle of ISP is proposed to build a stable and expandable network.(4)In the process of concrete implementation of two kinds of complex switching networks,the problems need to be considered when the routing reflection and the alliance migration are put forward;then a method to migrate one network architecture to another is put forward to ensure the correct and minimum flow loss.At the same time,the above migration method is demonstrated and applied in the case of the migration from the i BGP fully connected network architecture to the network architecture based on the alliance.Then,the migration strategy is proposed for Connectionless Network Service which is often used in the enterprise,and the migration steps and experimental results are described in detail with specific examples.(5)This paper presents a maximum reliability multipath routing algorithm.Based on the widely used mobile autonomous network,this paper presents a routing algorithm that satisfies the maximum reliability multipath in the face of the multipath topology that changes at any time.First of all,the multipath problem in the ad-hoc network is analyzed,and a maximum reliability multipath selection algorithm is proposed to select a reliable path set.Then,the multipath reliability model is established,and the wireless environment is experimented and experimental results are analyzed by Matlab software.
