EthErnEt Quality of SErvicE MEaSurEMEntS
Data services are making a significant shift toward supporting a variety of applications on the same network. Multiservice offerings
such as triple-play services have fuelled the need for QoS testing to ensure the condition and reliability of each service and fully
qualify SLA parameters. The FTB-8120NGE/8130NGE allow service providers to simultaneously simulate and qualify different
applications through their multiple stream application. The user has the capability to configure up to 10 streams with different
Ethernet and IP QoS parameters such as VLAN ID (802.1Q), VLAN Priority (802.1p), VLAN stacking (802.1ad Q-in-Q), ToS
and DSCP. Specific stream profiles to transmit Voice-over-IP (VoIP), video and data can be selected for each stream. For each
stream, measurements for throughput, latency, frame loss and packet jitter (RFC 3393) are available simultaneously, allowing fast
and in-depth qualification of all SLA criteria.
PBB-tE and MPlS: carriEr EthErnEt tranSPort Solution tESting
As technologically-sophisticated commercial and residential consumers continue to drive demand for premium, high-bandwidth
data services such as voice and video, service providers worldwide are evolving their transport infrastructures to support these
bandwidth and quality intensive services. No longer is an all-IP core sufficient; providers must now expand their IP convergence
to the edge/metro network, in a cost-effective, quality-assured manner.
Two Ethernet tunneling technologies address these requirements: Provider Backbone Bridge-Traffic Engineering or PBB-TE (also
referred to as PBT) and transport MPLS. These two technologies enable connection-oriented Ethernet, providing carriers with a
means of offering scalable, reliable and resilient Ethernet services. The PBB-TE and MPLS options on the FTB-8120NGE/8130NGE
offer service providers a comprehensive field tool to efficiently qualify Ethernet services from end to end, validating metro and core
tunneling technologies.
tcP throughPut
The Internet protocol (IP) and transmission control protocol (TCP) together form the essence of TCP/IP networking. While IP deals
with the delivery of packets, TCP provides the integrity and assurance that the data packets transmitted by one host are reliably
received at the destination. Applications such as hypertext transfer protocol (HTTP), e-mail or file transfer protocol (FTP) depend
on TCP as their delivery assurance mechanism within networks. Customers deploying such applications expect not only physical
and link level SLAs from their service providers, but assurance that their TCP traffic requirements will be supported across the
network. The TCP throughput feature offers Ethernet service providers the capability of measuring and validating that the services
offered to their customers support the TCP traffic performance they expect.
EthErnEt advancEd trouBlEShooting
The FTB-8120NGE/8130NGE provide a number of advanced features essential for in-depth troubleshooting in the event of
network failures or impairments. The advanced filtering option allows the user to configure up to ten filters each with up to four
operands, which will be applied to the received Ethernet traffic. Detailed statistics are available for each configured filter providing
the user with critical information required to pinpoint specific problems. Other advanced troubleshooting tools include advanced
auto-negation and flow-control capabilities.
The FTB-8120NGE/8130NGE also support full-line-rate data capture and decode. This key troubleshooting tool enables field
technicians to easily identify complex network issues. The comprehensive capture feature includes the capability to configure
capture filters and triggers to quickly zero in on network events.
