Problems solved by technology

The TCP / IP protocol was not designed with security in mind at the beginning, so the security provided for TCP / IP is an afterthought, and it is difficult to provide real security for data in modern networks.

Embodiment

[0028] Example: figure 2 The test platform for online migration of LAN virtual machines under the NDN network is shown. image 3 It is a test platform for online migration of WAN virtual machines under NDN network. In the figure, HOST_A is the source host, HOST_B is the destination host, HOST_C is the application client, HOST_VM is the virtual machine, S is the switch, and R is the router. The configurations of HOST_A and HOST_B are i3 processor, 8GB memory and 8GB swap partition; the configuration of HOST_C is Intel Core 2 Duo processor, 2GB memory and 8GB swap partition; the operating systems of HOST_A, HOST_B, HOST_C and HOST_VM are all linux Ubuntu12.04.2, the kernel version is 3.5.0-23-generic, using the QEMU-KVM-1.0 virtual machine.

[0029] Testing the virtual machine online migration of the present invention method on the above evaluation platform specifically includes the following steps:

Abstract

The invention relates to an on-line migration method of a virtual machine in a wide area network under future network NDN (Named Data Network). The method comprises the following steps: a migration data sending side writes migration data of the virtual machine into a standard input stream, and packages the data into a data message to be issued in a content buffer area; a migration data receiving side requests the migration data sending side for data, the migration data sending side inquire the data from the content buffer area and sends the data to the migration data receiving side; and the migration data receiving side receives the data message, analyzes the data and writes the data into a standard output stream, and the virtual machine reads the data from the standard output stream and is loaded. Compared with the prior art, the on-line migration method of the virtual machine in the wide area network under future network NDN realizes on-line migration of the virtual machine in the wide area network under the NDN network, enables applications on the virtual machine to be kept continuous in the migration process of the virtual machine, realizes seamless migration of the virtual machine, ensures the network to be unimpeded through a dynamic self-adaptive mechanism after the migration is completed, and is of great significance to cloud computing and load balance of the future network NDN.

Description

technical field [0001] The invention relates to the technical fields of network communication and cloud computing, in particular to a method for online migration of a virtual machine in a wide area network under the future network NDN. Background technique [0002] Virtualization integration server virtualizes physical servers into virtual servers through virtualization, virtualizes more servers with the same number of physical servers, makes full use of resources, and can obtain huge savings in power and cooling costs. The migration of the virtual machine provides the conditions for the load balancing of the server cluster, and the flexible and dynamic management manages and adjusts the resources of the cloud computing environment. [0003] With the continuous development of Internet technology, the problems of contemporary IP networks are increasingly exposed. The narrow waist of IP was originally designed to realize network communication, but it has gradually failed to m...
