Abstract

The invention relates to a method for realizing online migration based on a bidirectional pipeline manner under NDN (Named Data Networking). The method comprises the following steps: (1) a name space design step in the NDN: three name spaces used for naming a data packet are determined; (2) a bidirectional pipeline communication manner: a bidirectional pipeline communication data packet passes between a data requiring party and a data sending party; the bidirectional pipeline communication manner comprises an inverted sequence and packet dropout processing: a caching region for preserving Data which reaches in advance due to the inverted sequence or is produced in advance is set, and the Data is obtained again by adopting a retransmission timeout mechanism; when the time is out for multiple times, a request is done again by adopting a sub-package manner; and (3) a performance testing step. Compared with the prior art, the online migration of a virtual machine of a local area network and a wide area network under an NDN network is realized, so that the application on the virtual machine keeps continuous in the migration process of the virtual machine, and the seamless migration of the virtual machine is realized; by the aid of a dynamic self-adapted mechanism, the network is smooth after the migration is finished.

Description

technical field

[0001] The present invention relates to the field of network communication technology and cloud computing technology, and in particular to a method for realizing virtual machine online migration under NDN (Named Data Networking) based on a bidirectional pipeline. Background technique

[0002] With the development of the network, more and more limitations have appeared in the TCP / IP structure, including scalability, stability, security and mobility. These shortcomings have led the academic community to start research on future networks. FIA-NP currently has three main projects: MobilityFirst-NP, Named Data Networking-NP, and eXpressive Internet Architecture (XIA). Among them, the core concept of NDN is that the network does not focus on location (Where), but data (What). This transformation not only greatly improves the flexibility, scalability and mobility of the network, but also the built-in security strategy Improve the security of the network and its ap...

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0037] A method for realizing online migration of a virtual machine based on a two-way pipeline under NDN includes the following steps:

[0038] (1) Name space design steps in NDN: build NDN for data migration, data packets in NDN are divided into Interest and Data, and names in NDN are independent of the NDN forwarding program (NFD) but a very important part, so the virtual machine During live migration, three namespaces are defined for naming packages:

[0039] The first name space is used to identify the data package in the migration process;

[0040] The second name space is use...
