Abstract

The present invention relates to a method for realizing online migration of a virtual machine based on a two-way pipeline under NDN, comprising the following steps: (1) Name space design step in NDN: defining three name spaces for naming data packets; (2) two-way Pipeline communication steps: data packets are communicated between the data requester and the data sender through a two-way pipeline; the two-way pipeline communication steps include reverse order and packet loss processing: set a buffer area for storing data that arrives in advance or is generated in advance due to reverse order, and uses The timeout retransmission mechanism is used to re-acquire the Data. When the timeout is repeated multiple times, the request is re-requested in the form of sub-packages; (3) Performance test steps. Compared with the prior art, the present invention realizes the online migration of the virtual machine in the local area network and the wide area network under the NDN network, keeps the application on the virtual machine in the process of virtual machine migration, realizes the seamless migration of the virtual machine, and The dynamic self-adaptation mechanism is used to ensure that the network is smooth after the migration is completed.

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 online migration of a virtual machine based on a bidirectional pipeline under NDN (Named Data Networking). 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 i...

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...
