Quantitative estimates for the continuity property of queueing systems of type $G|G|\infty$

Queueing systems of type $G|G|\infty$ are analyzed by the author's method proposed in [2] and [3] for studying stability of systems of type $G|G|1$. General quantitative estimates for the continuity property of such systems are obtained. In a number of particular cases, these estimates can be expressed in an explicit form.
