在带宽分配模型中应用自治

Applying Autonomy with Bandwidth Allocation Models

Rafael Freitas Reale, Romildo Martins da S. Bezerra, Joberto S. B. Martins

摘要:

带宽分配模型(BAM)是通常用于网络的资源分配方法。BAM当前被应用于处理诸如MPLS DS-TE网络中的带宽分配(LSP设置)的资源。通常,BAM按类定义资源限制,并按需分配可用资源。这对于管理大型复杂系统(如路由网络)通常是必要的。GBAM是一种新的通用BAM,通过配置,它包含了现有BAM(MAM、RDM、G-RDM和AllocTC共享)的行为。实际上,G-BAM通过简单地调整其配置参数来再现任何当前可用的BAM行为。本文重点研究了使用自治与带宽分配模型(BAM),以提高性能和促进MPLS DS-TE网络的管理的适用性。它是研究BAM交换的适用性,使用一个框架,具有自主特性。简单地说,它是研究BAM行为之间的切换和BAM的重新配置与不同的网络流量的情况下,通过使用GBAM。仿真结果表明,BAM行为的自主切换的基础上,高层次的管理规则(SLA,QoS或其他警察)可能会导致改善整体网络管理和操作参数,如链路利用率和抢占。

英文摘要:

Bandwidth Allocation Models (BAMs) are resource allocation methods used for networks in general. BAMs are currently applied for handling resources such as bandwidth allocation in MPLS DS-TE networks (LSP setup). In general, BAMs defines resource restrictions by class and allocate the available resources on demand. This is frequently necessary to manage large and complex systems like routing networks. GBAM is a new generalized BAM that, by configuration, incorporates the behavior of existing BAMs (MAM, RDM, G-RDM and AllocTC-Sharing). In effect, any current available BAM behavior is reproduced by G-BAM by simply adjusting its configuration parameters. This paper focuses on investigating the applicability of using autonomy together with Bandwidth Allocation Models (BAMs) for improve performance and facilitating the management of MPLS DS-TE networks. It is investigated the applicability of BAM switching using a framework with autonomic characteristics. In brief, it is investigated the switching among BAM behaviors and BAM reconfiguration with distinct network traffic scenarios by using GBAM. Simulation results suggest that the autonomic switching of BAM behaviors based on high-level management rules (SLAs, QoS or other police) may result in improving overall network management and operational parameters such as link utilization and preemption.
