MACsec Configuration and Operation
Encryption is a critical element of many network designs, to ensure confidentiality and defend against potential threats such as replay attacks. Both MACsec and IPSec provide strong encryption, with different performance levels that make them suitable for different roles.
7170 Series Network Switch Datasheet
Highly dynamic cloud data center networks continue to evolve with the introduction of new protocols and server technologies. The Arista 7170 series are purpose built, programmable fixed configuration data center switches for flexible, dense 100GbE solutions at spine layer and 25/50GbE solutions for storage and compute.
Combining Arista EOS and a highly programmable switch architecture with customizable system resources, the 7170 Series delivers unique features for traditional and new network based applications and services.
Cognitive Campus Network
Campus networks are undergoing a massive transition to handle unprecedented challenges, as enterprises move to IoT-ready campuses. Indeed, network architects face a new mandate to better align with morphing business needs and ubiquitous user workloads, using open software-driven cloud principles for a consistent, uniform enterprise-wide operational experience. The 1990s saw the challenge of information sharing via the internet and email. The 2000s marked the convergence of business systems and PBX networks, improving productivity and lowering operational costs.
Arista EOS® Precision Data Analysis with DANZ
Traffic volumes are exploding in the datacenter due to the increasing efficiency and density of highly-virtualized cloud computing infrastructures. A single application or storage server, now connecting at speeds of 10Gbps, 25Gbps and even 50Gbps, can now generate bi-directional flow rates in excess of tens of billions of packets per day with aggregate daily traffic in many cloud data centers measurable in petabytes and beyond. To handle these loads, deployments of multi-path 100Gbps Ethernet spine and leaf architectures are becoming the norm. Owing to the large volumes of traffic, traditional methods of capturing and analyzing traffic flows require a dramatic rethink in density and performance for data aggregation and visibility.
Arista FlexRoute™ Engine
Suffice to say, consumer video consumption behavior has undergone a rapid transformation. The ubiquitous stationary TV has been replaced with far greater viewing options and an unprecedented flexibility to consume any content at any place on any screen. This revolution, first ushered in by the Digital Video Recorder (DVR) in the late 90s has culminated into a new world order of “binge” watching and freedom from the constraint of linear programming schedules or the anchor of the stationary living-room TV set.

Transforming the Telco Central Office with NFV and SDN
The data revolution is transforming the consumer and business landscape with intelligent transportation, smart cities, home automation and IoT devices. The common theme: data is everywhere and is growing exponentially. Over the years, network service providers have invested in multiple technology transitions in mobile, broadband access and business services. This has led to disparate SP networks, each with its own proprietary architecture, leading to enormous OPEX and CAPEX budget bloats. More importantly, these silos have crippled their ability to introduce new services or scale out existing services in an agile manner. With increased bandwidth demand and reduced revenue per bit forecasted, service providers are under pressure to reduce their TCO and transform their infrastructure to drive innovation, all while being more agile in service delivery.
Cloud Interconnect: DWDM Integrated Solution For Secure Long Haul Transmission
The phenomenal growth in mobile, video streaming and Cloud services is driving the need for higher bandwidth within datacenters. Global IP traffic is estimated to grow at a compound annual growth rate (CAGR) of 23 percent from 2014 to 2019. These same applications are also driving the need to interconnect geographically dispersed datacenters to maintain seamless content delivery and to provide application agility without compromising on customer data security from external threats. The implications of poor data protection can be detrimental for an organization, ranging from government fines to costly lawsuits. To keep up with the global demand for higher bandwidth, datacenter operators need an interconnect solution that is dense, economically efficient and secure. This white paper will provide an overview of the underlying technology of Coherent DWDM and the advantages of the Arista 7500E Series DWDM solution.
Arista DWDM Solution and Use Cases
The introduction of the Arista 7500E Series DWDM solution expands the capabilities of the Arista 7000 Series with a new, high-density, high-performance, DWDM line card.
Until now, providing secure high-speed Metro and Long Haul, high-bandwidth Ethernet connectivity between customer locations required separate layer 2 and 3 IP networking devices, passing each connection through dedicated encryption devices and provisioning optical channels over active DWDM solutions.
The advent of Cloud Computing changes the approach to data center networks in terms of throughput, resilience, and management. Cloud computing is a compelling way for many businesses, small (private) and large (public) to take advantage of web based applications. One can deploy applications more rapidly across shared server and storage resource pools than is possible with conventional enterprise solutions.
