Expression

Words {words}

• mitigate
  • 减轻

One of the important goals of data center networks is to avoid or mitigate the effect of network bottlenecks on the operation of the computing services offered

• diversified
  • 多变化的，各种的

By using specialized optimization algorithms and diversified configuration options.

• seamless
  • smoothly and continuously, with no apparent gaps or spaces between one part and the next
  • 无缝衔接的，平滑的

the load balancing service can take the appropriate actions to seamlessly distribute the traffic among the available servers.

• paramount
  • more important than anything else;
  • 至关重要的

Another aspect of paramount importance is the portability of the programming language.

• Amenable :
  • willing to accept or be influenced by a suggestion;
  • 意为顺从的，愿意接受建议的，耳朵软的之类的意思。在 OpenFlow 一文中，作者将 Amenable 放在句首，来表达需要实现的功能。

Amenable to high-performance and low-cost implementations.

• sophisticated
  • having a good understanding of the way people behave and/or a good knowledge of culture and fashion:
  • intelligent or made in a complicated way and therefore able to do complicated tasks:
  • 意为复杂精巧的，精于世故的，精通的，富有经验的。此处来形容功能精细复杂的东西。

One can also imagine more sophisticated controllers that dynamically add/remove flows as an experiment progresses.

• envisage
  • to imagine or expect something in the future, especially something good;
  • 想象，设想，用来描述技术的前景

One could envisage an extension to Ethane in which a policy dictates that particular flows are sent to a user’s process in a controller, hence allowing researcher-specific processing to be performed in the network.

• inertia
  • lack of activity or interest, or unwillingness to make an effort to do anything
  • 惰性、惯性、懒惰。作者用来表述某个东西难以推动发展

Due to the inertia of current IP networks, a new routing protocol can take five to ten years to be fully designed, evaluated, and deployed.

• alleviate

  • to make something bad such as pain or problems less severe
  • 减轻某种痛苦，减轻，缓和，使镇定

• proliferate

  • to increase a lot and suddenly in number
  • 激增、增殖，作者用来表达大量东西涌现，也就是激增的含义。

To alleviate the lack of in-path functionalities within the network, a myriad of specialized components and middleboxes, such as firewalls, intrusion detection systems, and deep packet inspection engines, proliferate in current networks.

• ubiquitous

  • seeming to be everywhere

  • 到处存在的

    abstractions are essential tools of research in computer science and information technology, being already an ubiquitous feature of many computer architectures and systems.

• anchor

  • to lower an anchor into the water in order to stop a boat from moving away;
  • to make something or someone stay in one position by fastening him, her, or it firmly;
  • 锚状物、固定、支撑，赖以支撑的人、物。作者用来表达一个技术依赖于一些东西（这些东西可以避免）

However, these technologies are anchored on a box-by-box basis configuration.

• analogy
  • 相似，类似，类比
  • 翻译说是举例来说，我感觉说是类比来看也可以：

The base network service functions are what we consider the essential functionality all controllers should provide. As an analogy, these functions are like base services of operating systems, such as program execution, input/output (I/O) operations control, communications, protection, and so on.

Sentences {sentences}

• 同时

for instance, allowing the distribution and directing of large groups of client requests without requiring controller intervention for every new flow. In tandem, operation in reactive mode may still be used when traffic bursts are detected.

• 更不用说

Commercial switches and routers do not typically provide an open software platform, let alone provide a means to virtualize either their hardware or software.

• 长期看来前景很不错 （现在没啥用）

This approach is promising in the long-term, but for the time being is targeted at large switching centers and is too expensive for widespread deployment in college wiring closets.

• 来满足

Programming languages can also provide specialized abstractions to cope with other management requirements, such as monitoring.

Professional Expression {professional-expression}

• fine-grained <==> coarser grained 细粒度，粗粒度；
• race-free 非竞争的；
• single point of failure 单点故障；
• heterogeneity 异质性；
• Wrapping Up Remarks 总结，结束语；
• introduce 引入，提出。

Good Sentences {good-sentences}

The controller application needs to monitor the network traffic and use some sort of threshold in the flow counters to redistribute clients among the servers when bottlenecks are likely to happen.
