Glossary of Terms

ANLT

Auto-Negotiation and Link Training.

API

Application Programming Interface.

CG

Connection Group. A Connection Group is a basic building block when creating L47 traffic, and it consists of a configurable number of TCP connections.

CRUD

Create, read, update, and delete operations

DUT

Device Under Test.

HL-API

Xena OpenAutomation High-Level Python API.

HL-FUNC

Xena OpenAutomation High-Level Functions.

I2C

I²C (Inter-Integrated Circuit, eye-squared-C), alternatively known as I2C or IIC, is a synchronous, multi-controller/multi-target (controller/target), packet switched, single-ended, serial communication bus.

Index Manager

An Index Manager manages the subport-level resource indices such as stream indices, filter indices, connection group indices, match term indices, length term indices, etc. It automatically ensures correct and conflict-free index assignment.

LL-API

Xena OpenAutomation Low-Level Python API.

Load Profile

A load profile defines a start time and a duration of each of the ramp-up, steady, and ramp-down phases of a connection group.

Module Manager

A Module Manager helps you access test modules. There is one Module Manager per tester.

Module Type

Module Type corresponds to the model of a test module. Modules of different module types have different port counts, port speeds, capabilities, etc. Examples of module types are Loki-100G-5S-1P, Odin-10G-5S-6P-CU.

Port Manager

A Port Managers helps you access test ports. There is one Port Manager per test module.

Port Type

Port Type corresponds to the module that the port belongs to. All ports on the same module have the same port type.

PRBS

Pseudorandom Binary Sequence is a binary sequence that, while generated with a deterministic algorithm, is difficult to predict and exhibits statistical behavior similar to a truly random sequence.

Resource Manager

HL-API provides an easy way to manage subtester test resources, including obtaining test resources and managing indices.

Test Resource

Test chassis, test module, and test port, both hardware and virtual are referred to as test resources. A user must have the ownership of a test resource before be able to perform testing.

TGA

Traffic Generation and Analysis.

TID

Test Payload Identifier. It is used to identify a sending stream.

TPLD

Test Payload Data. Each Xena test packet contains a special proprietary data area called the Test Payload Data, which contains various information about the packet. The TPLD is located just before the Ethernet FCS.

XOA

Xena OpenAutomation

XOA CLI

XOA Command-Line Interface. Xena provides a rich set of CLI commands for users to administer test chassis for test automation. Read more here.

XOA Core

Xena OpenAutomation Core is an open test suite framework to execute XOA Test Suites as its plugins.

XOA Python API

The foundation of Xena OpenAutomation is its Python API (XOA Python API) that provides interfaces for engineers to manage Xena hardware and virtual test equipment.
