An autonomous system (AS) 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.

autonomous system number (ASN)

ASN refers to autonomous system number and is a unique numerical ID allocated to each AS for use in BGP routing.

ASN Path Prepend

The number of times to add the local ASN to the BGP path to prioritize route advertisements. The ASN path length determines the route advertisement priority for outgoing BGP paths. The route with the shortest AS path has the highest preference, and it wins over any longer path advertisements. AS path prepending lengthens the path to lower the path priority. For example, 2 prepends the ASN to the existing AS path twice, creating an AS path length of 3.

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 Cross Connects (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 ONE Portal when a customer provisions a new Port.

When you order a new Port that is 10 Gbps or higher, enabling the Link Aggregation Control Protocol (LACP) allows you to use it in a link aggregation group (LAG). We recommend that you enable LACP even if you only require a single Port at that time. This prevents service interruption if later you decide to enable LACP on the Port.

A LAG bundles physical ports to create a single data path, where the traffic load is distributed among the ports to increase overall connection reliability. This feature provides aggregate bandwidth, enhanced resiliency, and efficient use of resources. Other terms used to describe a LAG include port trunking, link bundling, and channel bonding.
