Terminology

Aka in Ipanema

Description

AG (Application Group)

-

A classification within SD-WAN that groups applications based on shared characteristics or policies, facilitating targeted network management and optimization.

APO (Application Performance Optimization)

-

The software agent providing the SD-WAN services such as Visibility, Control, DWS, and WAN optimization.

ASR (Asymmetric Routing)

-

A routing situation where the path taken by packets sent from source to destination is different from the path taken by packets sent from destination to source.

CAD (Cloud Application Database)

-

A database provides directory services for SaaS applications and web traffic, allowing them to be identified by their FQDNs and server IP addresses.

CBQ (Class-Based Queuing)

-

A queuing discipline used in network traffic management to divide user traffic into a hierarchy of classes and allocate bandwidth to each class based on defined policies, allowing for prioritization and bandwidth sharing among different traffic types.

CPE (Customer Premises Equipment)

-

The equipment installed at the customer's premises that connects to the SD-WAN network, acting as the endpoint for WAN services.

D/J/L

-

Delay/Jitter/Loss

DPI (Deep Packet Inspection)

-

A technique to inspect and classify network traffic flows based on packet data payloads.

DWS (Dynamic WAN Selection)

-

Ability to dynamically select the best WAN link(s) for each application based on policies and real-time conditions.

EDD (Effective Density of Demand)

-

A metric that represents the actual bandwidth demand of an application or user; the more bandwidth available, the better.

EdgeSentry

-

ExtremeCloud SD-WAN's Cloud Security feature, delivered through Check Point, providing access control, threat prevention, HTTPS inspection, and more.

EQS (Experience Quality Score)

AQS (Application Quality Score)

A quantifiable measure of application performance and user experience. (value range is 1~10, high number is good quality)

Fabric to the Edge

-

Extending the SD-WAN fabric to the edge/branch locations for unified management and security.

GDC (Global Data Center)

-

Centralized data centers that host services and data for access from any global location.

Goodput

-

The number of useful bits received at the application layer, i.e. the payload of TCP and UDP packets received at the downstream side (retransmitted, out-of-sequence, and lost packets are not counted).

HTB (Hierarchy Token Bucket)

-

A hierarchical classful queueing discipline for traffic control in Linux-based systems, often used in SD-WAN solutions for bandwidth management and Quality of Service (QoS) enforcement.

IBA (Ipanema Behavior Aggregates)

-

Active connection to a remote site via a given NAP.

IBAs are dynamically created for each remote site to which traffic is to be sent. IBAs remain active for 2 hours after the last packet was sent to the destination.

IHAP (Ipanema High Availability Protocol)

-

A proprietary protocol used by Ipanema (now Extreme Networks) SD-WAN appliances for high availability and failover.

(discontinued)

IMA

Ipanema Mobile Agent, software agents for Windows desktops

IPE

ip|engine (or ip|e)

SD-WAN appliance.

ip_coop

-

Cooperation (for RVCs)

ip_fast

-

ip|fast = Application Control

(discontinued)

ip_sws

SoftWOC (Software WAN Optimization Controller) Server

ip_true

-

ip|true = Application Visibility

ip_xcomp

-

ip|xcomp = compression = WAN optimization

ISW

-

IPE’s internal vSwitch

ITP

-

Ipanema Time Protocol for time synchronization

Jitter

-

The variation in latency or delay for packets belonging to the same flow.

NAP (Network Access Point)

-

Points or links in the network where access is provided to the users or other networks, playing a crucial role in traffic routing and connectivity in SD-WAN.

OBPS

-

object-based path selection = DWS

QoE (Quality of Experience)

Measures the overall satisfaction of the end-user with an application or service, considering factors like speed, reliability, and usability. (measured by the EQS)

RDC (Regional Data Center)

-

Data centers located in specific regions to provide localized services and data storage.

RTT (Round Trip Time)

-

The time it takes for a data packet to travel from the source to the destination and back.

• Min: shortest Round Trip Time

• Avg: average Round Trip Time

• Max: longest Round Trip Time

RVC (Remote Visibility + Control)

tele|engine

Provides remote visibility and control where the branch doesn't have an SD-WAN appliance.

-

SAC

SALSA Application Controller

-

SALSA

Scalable Application Level Service Architecture.

A SALSA unified portal gives access to ip|uniboss, ip|boss, ip|dashboard and ip|reporter web.

-

SNC

SALSA Network Controller

SNC (Service Network Controller)

-

Network Controller that serves as the interface between the Orchestrator and the Router embedded in the ip|engines.

SPH

-

Smart|path, the initial name of DWS

SR (Slave Return)

-

Return path.

SRT (Server Response Time)

-

The time it takes for a server to respond to a request.

SWG (Secure Web Gateway)

-

A security solution that monitors and filters web traffic for threats and policy enforcement. (such as Zscaler)

UC (User Class)

-

User Class is the original name for Application Group, so uc = AG

VTI (Virtual Tunnel Interface)

-

A virtual interface used to encapsulate and route traffic over a secure IPsec tunnel. (AWS, Azure, Cisco router, etc.)

XIQ (ExtremeCloud IQ)

-

Cloud-driven networking solution offering unified management of access points, switches, and SD-WAN.

ZBF (Zone-Based Firewall)

-

Built-in firewall that implements VPN traffic segmentation based on configured zones.

ZTP (Zero-Touch Provisioning)

-

Ability to automatically provision and configure SD-WAN devices with minimal manual intervention.
