【摘要】:為有效解決多租戶對(duì)可分割云資源分配的競(jìng)爭(zhēng)問題,提出一種基于效用函數(shù)的最優(yōu)化分配策略。通過定義競(jìng)爭(zhēng)租戶對(duì)資源分配的評(píng)估函數(shù)和代價(jià)函數(shù),建立效用最優(yōu)化模型。討論不同形式的代價(jià)函數(shù)對(duì)最優(yōu)化分配結(jié)果的影響,驗(yàn)證在該效用模型下資源分配存在納什均衡解,仿真對(duì)比不同形式代價(jià)函數(shù)下資源分配的性能表現(xiàn)。實(shí)驗(yàn)結(jié)果表明,在求解租戶社會(huì)福利最大化過程中,線性代價(jià)函數(shù)和凸性代價(jià)函數(shù)均可以使分配過程收斂到唯一解上,但線性代價(jià)函數(shù)可以為單個(gè)租戶帶來最優(yōu)的系統(tǒng)效率,實(shí)現(xiàn)多租戶環(huán)境下整體社會(huì)福利的最大化。
[Abstract]:In order to solve the problem of multi-tenant competing for partitioned cloud resource allocation, an optimal allocation strategy based on utility function is proposed. The utility optimization model is established by defining the evaluation function and cost function of resource allocation for competing tenants. The effects of different cost functions on the optimal allocation results are discussed. It is verified that there is a Nash equilibrium solution for resource allocation under the utility model. The performance of resource allocation under different form cost functions is compared by simulation. The experimental results show that both linear cost function and convexity cost function can converge to the unique solution in the process of maximizing the social welfare of tenants, but the linear cost function can bring the optimal system efficiency for a single tenant. To maximize the overall social welfare in a multi-tenant environment.
