This topic defines terminology related to the Megaport network and services.
IEEE 802.1Q is the networking standard that supports virtual LANs (VLANs) on an Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. Also informally known as dot1q.
The start of the connection–the Port, MCR, or MVE.
Megaport connections need an A-End and a B-End. The connection starts with an A-End. Most often, the Port is the A-End. The B-End is the other end of the connection: it can be a Port, an Internet Exchange, a Marketplace connection, or a cloud service provider.
Application program interface (API) is a set of routines, protocols, and tools for building software applications. An API specifies how software components should interact and APIs are used when programming graphical user interface (GUI) components. The Megaport API allows customers and partners to integrate directly into our platform for automation and service creation (see dev.megaport.com).
An autonomous system number (ASN) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators on behalf of a single administrative entity or domain.

Layer 1 (L1)
Layer 1 of the OSI model conveys the bit stream (electrical impulse, light or radio signal) through the network at the electrical and mechanical level. It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards, and physical aspects. A fiber optic cable/SFP terminations would be considered Layer 1, as well as the physical Port.
Layer 2 (L2)
Layer 2 of the OSI model is the data link layer. This provides node-to-node data transfer (a link between two directly connected nodes). Most Megaport virtual services (VXCs) operate at this layer. Layer 2 is divided into Media Access Control (MAC) layer (controls how devices in a network gain access to medium and permission to transmit), and Logical Link Control (LLC) layer (responsible for identifying network layer protocols and then encapsulating them and controls error checking and frame synchronization).
Layer 3 (L3)
Layer 3 of the OSI model is the network layer. It translates logical network address into physical machine address (IP addressing). Layer 3 routers analyze traffic based on address details and forward appropriately, requiring knowledge of the details generally exchanged in BGP sessions for routing table exchanges.
Letter of Authorization (LOA)
A document that customers need to present to their data center provider to establish the physical cross-connect from their data center services to their Port. The LOA is provided via the Megaport Portal when a customer provisions a new Port.

Open Systems Interconnection (OSI)
A model that characterizes and standardizes the communication functions of a telecommunication or computing system. Most Megaport products are Layer 2 (or L2) with some of the OSI constructs pushing into Layer 3 (L3) where IP addressing information is exchanged, known as an L2/L3 service.
Platform as a Service vendors offer a development environment to application developers. The provider typically develops toolkit and standards for development and channels for distribution and payment. In the PaaS models, cloud providers deliver a computing platform, typically including operating system, programming-language execution environment, database, and web server without the need to manage any of the underlying operating system or host architecture.

Packet transfer delay (one-way latency measure).
802.1Q tunneling (also known as Q-in-Q or 802.1ad) is a technique used by OSI Layer 2 providers for customers. 802.1ad provides for both an inner and an outer tag whereby the outer (sometimes called S-TAG for service provider) can be removed to expose the inner (C-TAG or customer) tags that segment the data.
(Generally vertical) shafts through which cable baskets are routed. Also known as verticals.
route server (RS)
A route server provides a mechanism for the establishment of BGP routing exchanges in an Internet Exchange (IX or IXP). It simplifies the process of maintaining many peering partners across a fabric and also contributes to the network visibility and manageability. Route servers are generally deployed in pairs to allow for maintenance windows and general redundancy to support IX stability. Some offer a Looking Glass functionality used to view which peers maintain which routes and allow troubleshooting on network routing choices.
Round-trip time (RTT) is the length of time taken by a data packet to be sent to a destination, including the time it takes for an acknowledgment of that packet to be received back at the origin time. Also known as ping time.
