|Aggregator||On ECX, aggregators are NSPs and MSPs who provide multi-tenant services. Aggregators are both buyers of ECX service from Equinix and sellers of value-added services over ECX to their end customers|
The authorization key typically contains alpha-numeric characters and is a unique identifier authorizing Equinix to provision a connection towards the CSP
Note: To Equinix, authorization key is a generic term and is NOT encrypted on ECX. CSPs might use a different name to refer to the same key.
Example: Azure ExpressRoute refers to the authorization key as the service key, while AWS calls it the account ID.
|Buyer||A user who connects to an available service through ECX. A buyer can be an enterprise end customer of the seller service or an aggregator, managed service provider, network service provider or system integrator company that bundles its service offerings with ECX.|
|Cloud Service Provider (CSP)||A company that offers some type of cloud services to other businesses or individuals—such as cloud computing, cloud storage, cloud content delivery network (CDN) and others. Typical CSPs include Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS).|
|Connection||A general term referring to any solution that results in the ability to pass data from one point to another. Connections can be made with Layer 2 or Layer 3 technology. They may involve several parts or components and can be created from the portal or with APIs in a variety of ways.|
|Component/microservice||A piece of an overall solution that can be built individually or as part of a larger end-to-end solution.|
|End customer/end device/CPE||The entity and/or devices managed by that entity that ultimately interacts with the services bought over the ECX platform.|
|Layer 2 (switching)||
When the ECX Fabric makes forwarding decisions at the Ethernet protocol level (Layer 2), and does not examine the IP addressing the service.
|Layer 3 (routing)||
When the ECX Fabric makes customer traffic forwarding decisions by examining the IP addressing of that traffic.
|Managed Service Provider (MSP)||
A business entity that helps enterprises architect, build, and support a technology strategy that may include ECX. Often also called system integrators, consultants or others. MSPs frequently aggregate customers similar to an NSP.
|Network Service Provider (NSP)||
A business entity that provides and sells services such as network access (local loop, wide area network (WAN), Internet transit) and bandwidth. NSPs are also referred to as carriers.
A generic term referring to an entity that “provides” a service, including CSPs, NSPs, MSP and aggregators.
|Rate limit||A bandwidth control that is placed on a connection or service that limits the amount of traffic that can be sent or received to an amount less than the physical size of the ports. This is also referred to as a policer or “policing” a service, and is typically implemented using a VLAN on a sub-interface.|
|Seller||A user who makes their services available to end customers through ECX. This guide refers to sellers for shorthand, but ECX generally regards a “seller” as an activity rather than a static person.|
