FTB-8510B Packet Blazer
FIBRE CHANNEL NETWORK INTEGRITY TESTING
EXFO’s FTB-8510B Packet Blazer module also supports comprehensive Fibre Channel testing.
Interfaces
This module supports the following Fibre Channel interfaces:
Applications
Since most storage area networks cover large distances and Fibre Channel has stringent performance attributes that must be
respected, testing at each phase of network deployment is imperative to ensure appropriate service levels. EXFO’s FTB-8510B
Fibre Channel option provides full wire-speed traffic generation at FC-0, FC-1 and FC-2 logical layers, allowing BER testing for link
integrity measurements. Latency, buffer-to-buffer credit measurements for optimization, and login capabilities are also supported.
Buffer-to-Buffer Credit Estimation
Buffer-to-buffer credits are part of the flow control engine for Fibre Channel connections. This is a crucial configuration parameter
for optimal network performance. Usually, network administrators calculate the value by taking the traveled distance and the data
rate into consideration. However, since latency issues are not considered, poor accuracy is to be expected. The FTB-8510B
module is capable of estimating buffer-to-buffer credit values with respect to latency by calculating the distance according to the
round-trip latency time.
Latency
Transmission of frames in a network is not instantaneous and is subject to multiple delays caused by the propagation delay in the fiber and
by processing time inside each piece of network equipment. Latency is the total accumulation of delays between two endpoints. Some
applications such as VoIP, video and storage area networks are very sensitive to excess latency. It is therefore critical for service providers
to properly characterize network latency when offering Fibre Channel services. From the latency measurement that they perform,
the FTB-8510B Packet Blazer estimates buffer-to-buffer credit value requirements.
