Problems solved by technology

The usual method of network simulation is to simulate the characteristics of the network protocol stack and links through network simulation tool software. This method is targeted, but the disadvantage is that this method often only simulates the network protocol stack of each node, and cannot truly show the network The characteristics of the real host of each node in the network also affect the normal use of many network measurement tools in this type of network simulation

Embodiment

[0046] In order to solve the problem of network construction and simulation at the autonomous domain system level, the invention proposes an automatic network routing topology simulation method based on a router IP address allocation algorithm. The method proposed by the invention essentially uses a certain number of high-performance servers to simulate the network routing topology of the autonomous domain system level constructed by large-scale BGP routers.

[0047] Proceed as follows:

[0048] 1. Simulation conditions

[0049] It is assumed that the autonomous domain system-level information is given by two files, node-list and link-list (it can also be given in other forms). The node-list file is the individual information of the autonomous domain, including the autonomous domain number, autonomous domain name, and network prefix declared by the autonomous domain. The content of the link-list file is the adjacency information between autonomous domains. Each line in the l...

Abstract

The invention discloses an autonomous-domain-level network simulation method based on a virtualization technology, and relates to the field of network simulation and algorithm design. The method aimsat achieving the purpose that by utilizing a server cluster and the virtualization technology, a host in a network is created and simulated to construct autonomous-domain-level network routing topology. According to the method, one BGP router is simulated for each autonomous domain on one or more physical machines by adopting a virtualization means, BGP sessions among the BGP routers are created,and the simulated network topology is formed. According to collected autonomous domain numbers, prefixes declared by the autonomous domains, adjacency relationships of the autonomous domains and business relationships of the autonomous domains, the autonomous-domain-level network routing topology formed by the BGP routers on a certain scale is simulated on a limited number of physical machines. The simulated BGP router topology can truly reflect the collected adjacency relationships of the autonomous domains and attributes of links among the autonomous domains; each simulated BGP router conducts routing selecting according to BGP routing protocols, and the routing behaviors of the simulated BGP routers are identical to the behaviors of real BGP routers.

Description

technical field [0001] The present invention relates to the field of network simulation and algorithm design; in particular, the present invention relates to a method for assigning IP addresses to BGP routers according to the adjacency relationship at the autonomous domain level, and a method of simulating the topology of BGP routers on a physical machine using a series of technologies such as virtualization method. Background technique [0002] At present, the Internet and large Internet service providers (ISPs) are divided into a large number of autonomous domain systems (Autonomous System, AS), and the autonomous domain system defines the management area and the routing policy acting on the range of the autonomous domain system. The Internet-level routing structure is generally divided into two types: intra-domain routing and inter-domain routing. For intra-domain routing, there are multiple intra-domain routing protocols, including Open Shortest Path Finite (OSPF), Rout...
