FTB-8510B Packet Blazer
RFC 2544 TEST SUITE
The FTB-8510B Packet Blazer can perform the RFC 2544 test
suite for 10/100/1000M interfaces at all frame sizes and at full line
rate, allowing the provider to certify that the circuit is efficient and
error-free at 100% utilization. More importantly, when in dual test
set mode, the Packet Blazer allows bidirectional testing, providing
independent RFC 2544 test results for each direction (local
to remote and remote to local) simultaneously. This is especially
important when testing Ethernet services as traffic from each direction
often takes different paths in the network. Performance results can
therefore vary depending on the direction.
The Packet Blazer supports automated RFC 2544 testing, including
throughput, latency, burst (back-to-back) and frame loss. Since
everything is automated, it is easy for field technicians to obtain accurate,
efficient measurements and results with a clear pass/fail indication.
The Packet Blazer also generates SLA reports that can be given to
customers and used for future reference.
EFFICIENT TESTING LEADS TO RELIABLE PERFORMANCE
EXacTCP
The transmission control protocol (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)
rely on TCP as their delivery assurance mechanism.
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. ExacTCP, the TCP throughput feature for the FTB-8510B,
which is based on RFC 6349, provides accurate measurements of TCP metrics, such as throughput, roundtrip time (RTT) and
optimal window size.
MPLS, MPLS-TP and PBB-TE: Carrier Ethernet Transport Solution Testing
As technologically-sophisticated business and residential consumers continue to drive demand for premium, bandwidth-hungry
and quality-dependent services, such as voice and video, service providers worldwide are evolving their transport infrastructures
to support them. No longer is an all-IP core sufficient.
Ethernet tunneling technologies such as Provider Backbone Bridge-Traffic Engineering or PBB-TE (also referred to as PBT) and
transport MPLS address these requirements. These 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-8510B Packet
Blazer offer service providers a comprehensive field tool to efficiently qualify Ethernet services from end-to-end, validating metro
and core tunneling technologies.
Ethernet Advanced Troubleshooting
The FTB-8510B provides 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 the
critical information required to pinpoint specific problems. Furthermore, the FTB-8510B supports a traffic scan feature that allows
quick identification and monitoring of VLAN and MPLS flows on the network. This can help clearly identify top bandwidth users.
The FTB-8510B also supports full-line-rate data capturing and decoding. This key troubleshooting tool enables field technicians to
easily identify complex network issues. The comprehensive capture feature includes the capacity to configure filters and triggers
to quickly zero-in on network events.
Testing can be performed end-to-end or end-to-core, depending on
the SLA. Remote testing is also possible.
