Abstract

A mathematical model of joint servicing of priority real-time traffic and elastic data traffic in multiservice access nodes has been constructed and studied. Definitions of quality indicators for joint servicing of incoming requests for information services are provided. A system of statistical equilibrium equations is formed and its use for calculating the exact values of the introduced characteristics is considered. A method for approximate calculation of characteristics is proposed, based on the construction of a system of simplified equilibrium equations. It has been established that the obtained estimates of customer service indicators are asymptotically accurate in the region of large and small losses. The use of the developed method is shown to solve the problem of estimating the volume of traffic offloaded in an overload situation to other access nodes or to other frequency ranges in order to achieve values of specified QoS indicators and to solve the problem of planning the volume of required transmission resource of a multiservice access node.

估算多业务接入节点中实时流量和弹性数据流量联合服务特性的近似方法
摘要 构建并研究了多服务接入节点中优先实时流量和弹性数据流量联合服务的数学模型。定义了联合服务信息服务传入请求的质量指标。形成了一个统计平衡方程系统,并考虑了利用该系统计算所引入特征的精确值。在构建简化平衡方程系统的基础上,提出了一种近似计算特征的方法。结果表明,所获得的客户服务指标估计值在大损失和小损失区域内都是近似准确的。使用所开发的方法,可以解决在过载情况下为达到指定的服务质量指标值而向其他接入节点或其他频率范围卸载流量的估算问题,以及解决多服务接入节点所需传输资源量的规划问题。
