Extensible adaptation via constraint solving

[摘要] This work presents the design, implementation, and evaluation of a simple programming language for expressing scheduling policies for transmission of multiple objects across a shared network connection. A key design component of the language is the ability to express constraints among the objects to be transmitted. Policies can: make ordering constraints, such as ;;all text objects are transmitted before any image objects;;; express rules on the relative bandwidth allocations across objects of different types; reserve a certain amount of bandwidth or restrict transmission of a subset of objects. Because it is possible to express contradictory constraints, the system finds suitable approximate solutions when no precise solution is available.
