代码迁移技术( Code Mobility) What is code mobility? Code mobility is the capability to dynamically change the bindings between code fragments and the location where they are executed Involves a Change in bindings dynamically b Relocation of code Network nodea Node b 2021/24 Institute of Computer Software, Nanjing University
What is code mobility? ▪ Code mobility is the capability to dynamically change the bindings between code fragments and the location where they are executed. ▪ Involves: a. Change in bindings dynamically b. Relocation of code Network Node A Node B 2021/2/4 Institute of Computer Software, Nanjing University 3
Why Code Mobility Limitations and drawbacks with traditional approaches in large-scale distributed settings like the internet a. scalability (growing size of network, network partitions) b. Customizability (tailor functionality to specific needs) C. Flexibility (dynamic nature of comm. infrastructure) d. Extensibility (to add new features) 2021/24 Institute of Computer Software, Nanjing University
