boil down into

Traditional quality of service ( QoS) can be parted into int-serv and diff-serv. The former provides a relative QoS guarantee while the later provides absolute QoS guarantee. Both can boil down into a priority queue algorithm.

传统的服务质量（QoS）算法分为差别服务和集成服务两种，前者提供相对的服务质量保证，而后者则可以提供绝对的服务质量保证，二者最终都可以归结为优先队列算法。

Break them, boil them down into much smaller problems, and then find simple solutions for them.

各个击破，把大问题打碎成一个个小问题，再找到小问题的答案。

We have tried to boil all the evidence down into the simplest explanations while, at the same time, avoiding oversimplification.

有时，我们希望总结所有的论据得到一个简单的结论，同时又要避免一刀切似的过于简单。
