Слайд 6

Описание слайда:

Base components Test Engine Run on Linux Build all components of TE Control of Test Agents Keep track of configuration changes Run tests Centralized log gathering

Слайд 7

Описание слайда:

Test Agent Target-specific application Linux FreeBSD NetBSD Windows OpenSolaris Run on an auxiliary station or DUT Configuring station (interfaces,routes,etc.)‏

Слайд 8

Описание слайда:

Test Agent Generates/Handles network traffic: Packets representation in ASN.1 format Packet iteration, inter packet interval, number of packets Sophisticated incoming traffic matching Supported packet formats: IEEE-802.3, IEEE-802.1D, IEEE-802.1Q, IEEE-802.2 ATM, AAL5 ARP, IPv4, IPv6, PPP, ICMPv4, UDP, TCP, DHCP, SNMP ...

Слайд 10

Описание слайда:

Auxiliary Agent Black Box testing: Network protocols Interoperability External Interfaces (SNMP, CLI)‏ Access to external equipment: Sophisticated traffic generators Media-specific condition emulators

Слайд 11

Описание слайда:

Embedded Agent White Box testing: Module testing API testing DUT-specific management

Слайд 12

Описание слайда:

Proxy Agent Configure DUT Access to external equipment

Слайд 13

Описание слайда:

Test Engine Components Dispatcher Runs/terminates all modules Handles user interrupt events Builder Based on autoconf/automake/m4 Cross compilation of Test Agents Logger RCF (Remote Control Facility)‏ Configurator Tester

Слайд 14

Описание слайда:

Logger Provide unified logging interface for all TE components: Test Engine and Test Agents Time synchronization between Agents and Engine Sort out logs by timestamps Define a number of log levels Gather log dumps from Test Agents Extended format qualifiers (to log files, memory dumps, packets)‏ Save log messages into a binary file

Слайд 15

Описание слайда:

Remote Control Facility Starts Test Agents according to configuration file or on-fly requests Provides access to services exported by Test Agents Controls concurrent access to Test Agents

Слайд 16

Описание слайда:

Configurator Loads start-up configuration of Agents Keeps track of configuration changes Rolls back configuration to a specified point Restores configuration after Test Agent crash Save configurations in XML format
