Arista 的园区认知云网络基于三个原则：

通用云网络 - 作为传统供应商脆弱的专有解决方案的替代品，Arista UCN 是一种基于标准的开放型设计，专注于软件驱动的控制原则。Arista 的折叠 Spline™ 方法将传统的园区核心和聚合层整合为一个具有高可用性的简单单层。

认知管理平面 - 管理平面的一致性存在严重缺陷，园区与数据中心一样，需要数据驱动的分析。Arista 认为，可以在两者之间应用通用模型，从而节省客户的运营成本。认知管理平面基于 Arista CloudVision，是一个数据驱动的存储库，用于跨网络分析的自动化操作。

确保园区安全 - 保护园区样条需要采用全面的方法进行网络分段、设备合规和审计，以及与 Arista 安全合作伙伴的服务集成。Arista 通过 EOS 和 CloudVision 提供这些功能。

Arista Cognitive Unified Edge (CUE)

Commercial Business requirements are driving accelerated adoption of cloud based applications; this requires a highly adaptive networking edge, that is secure, mobile, compliant and ubiquitous whether in the office, working remote, or onboarding a myriad of IoT devices. Just as Data Centers have moved from rigid, highly structured infrastructures, to agile on demand infrastructures as a service, so has the need for Campus networks to move to Edge as a Service. Arista’s Cognitive Unified Edge (CUE) enables this market transition by encompassing a comprehensive portfolio of services that leverages Arista’s EOS Network Data Lake and advanced AI capabilities optimized for commercial and mid market customers to deliver an integrated management platform with built-in automation, visibility and security for wireless, wired and WAN network infrastructure.

CUE- The Next Evolution in Edge Communications

The next technology evolution in commercial campus networks whether small branches or large headquarter buildings stretches well beyond bandwidth capacity upgrades. Hardware is easily keeping pace with bandwidth needs, driven by Moore’s productivity law where high volume commodity chip technologies are quadrupling bandwidth speeds every 2-3 years.

Of bigger importance is designing these networks where they can be easily deployed, maintained, secured, and amortized especially as the number of services these networks offer continue to expand. Customers must look beyond gigabits per second, and the latest Wi-Fi access points offerings when choosing their edge networking solutions. They must take a cloud centric networking approach where many of the design principles that have transformed data centers to cloud infrastructures are similarly leveraged. At a high level this cloud centric approach views infrastructure as a combined set of services, where business outcomes are more easily mapped to a set of integrated IT technologies.

Automation, artificial data intelligence, pro-active remediation, advanced telemetry, virtualization, segmentation, video broadcasting, and simplified topology designs are just several of the technologies that embody a cloud centric network. All of these technologies are directly applicable to campus networks. The combination of these technologies, working together as a solution rich with a number of services, is what Arista defines as the Cognitive Unified Edge (CUE) and has many use cases from single site deployments to distributed branch and cloud:

CUE Use Cases

Arista CUE for Distributed Enterprises

Connect and Secure Branch Offices

The way we work is evolving. Enterprises have adapted to new cloud-based technologies and applications that have increased employee efficiency and provided a scalable pathway to continued business growth. Work teams, now composed of employees working in headquarter offices, remotely or in branch offices have become spread across increasingly large distances with a growing number of branch offices. While these distributed enterprises realize a range of important benefits in this transformative era, managing these dispersed networks and their connected devices can bring new challenges of cost, complexity, and control. Network administrators cannot be in all locations at once, however at any time they could be required to provide network expertise to adjust network configurations or resolve issues to maintain the network.

Arista’s Cognitive Unified Edge (CUE) helps distributed enterprises optimize their networks with centralized management, while also safeguarding their data and devices. CUE redefines enterprise networks with enhanced management, security, connectivity, flexible PoE switching, and Wi-Fi 6/6E offerings that work together seamlessly to ensure connectivity, protection, monitoring, and control across the entire network from headquarters to the network edge.

Distributed Enterprise

CUE Benefits

Remote management - centralized cloud-based management makes it easy to deploy, configure and manage on-premises, cloud-hosted and remote office appliances from any browser. Centralized management streamlines configuration of intelligent traffic routing between headquarters, branch offices and the cloud. Alerting, reporting, and policy management across sites has never been easier.

Business reliability and continuity - ensure secure connectivity to business-critical, cloud-hosted applications like accounting and CRM systems, as well as internal network resources. Sites with less reliable Internet service can leverage LTE for backup connectivity. Access points provide full functionality even when access to the cloud is not available. When an AP detects the loss of connectivity to the cloud, it continues operating normally which gives unmatched network uptime.

Optimize connectivity - comprehensive VPN options that work seamlessly with complete bandwidth shaping and optimization, and WAN balancing and WAN failover for locations with multiple WAN connections.

Right size form factor - efficiently connect smaller sites or sites with Internet Service Provider bandwidth limitations. Easily scale as the number of users at locations increase and as more locations are brought online.

Protect the growing attack surface - Broad endpoint device coverage, including IoT device protection and automatic detection and blocking of wireless threats.

Flexible deployment - Layer products into an existing network, with standards based interoperability and many physical and software appliances to service locations with just a few users to locations with hundreds of users.
