A Sequential Model to Predict Frequency Variations over a Clock Network

网络中的正确同步是其操作的重要组成部分。同步不足 ** 会影响服务质量，导致数据重传、数字内容失真 ** 和加密服务严重降级等损害。此外，精确、准确的时间使几乎所有 ** 基础设施成为可能，如数据中心、有线和无线通信、金融交易、工业 ** 网络和其他安全通信。今天的网络由成千上万个独立的时钟组成，它们以时间序列格式产生数据。在网络中保持不同时钟之间的时间一致是许多网络应用的基本要求。由于能够模拟时钟频率的变化，两个或多个时钟将更紧密地同步 **，特别是在参考/主时钟不可用的情况下。目前，这个问题没有得到有效的处理，因为一旦主时钟可用，时钟将被同步。这个项目 ** 旨在为这个问题构建一个数据驱动的解决方案。**在拟议的研究中，我们的目标是建立一个框架来预测时钟网络中每个时钟的频率变化，然后在真实的网络上对其进行评估，以实证验证框架的预测。即使在很短的时间内，也能准确预测时钟的频率变化，这使得一种解决方案比竞争对手具有显著的优势。要做到这一点，采用灵活的方法，使每个时钟 ** 独立于其他时钟建模，将为困难而重要的 ** 问题创造一个真正世界级的解决方案。该解决方案将节省大量的同步时间和成本，并增加Microsemi的竞争优势。这将直接有利于加拿大，因为Microsemi的更多收入意味着Microsemi在加拿大的更多投资，并雇用更多的加拿大人才来扩大现有产品的开发技术。

Proper synchronization in a network is essential component to its operation. Inadequate synchronization**compromises quality of service, leading to such impairments as data retransmission, digital content distortion,**and severe degradation of encrypted services. Moreover, precise, accurate time enables virtually all**infrastructures such as data centers, wired and wireless communications, financial exchanges, industrial**networks, and other secure communications.**Today's networks are composed of thousands of independent clocks that produce data in time series format.**Keeping consistent time among different clocks in a network is a fundamental requirement of many networked**applications. Being able to model how clock frequency varies, two or more clocks will be in tighter sync**especially under conditions where the reference/master clock becomes unavailable. Currently, this problem is**not handled efficiently, as clocks will be synchronized once the master clock becomes available. This project**aims at building a data-driven solution for this problem.**In the proposed research, our goal is to build a framework to predict frequency variation of each clock over a**network of clocks and then evaluate it on a real network to empirically verify the predictions of the framework.**The ability to accurately predict the frequency variation of a clock even for a short period of time gives a**significant advantage of one solution over competitors. To do so with a flexible approach such that each clock**is modeled independently of other clocks would create a truly world-class solution to a difficult and important**problem. The solution will save a huge portion of synchronization time and costs and increases Microsemi's**competitive advantages. This will be directly beneficial to Canada as more revenue for Microsemi means more**investment from Microsemi in Canada and hiring more Canadian talent to expand existing products with**respect to the developed technology.
