Data packet timestamping*: When the optional data
packet timestamping feature is enabled, select packets
flowing through the QFX5130 are timestamped with
references to the recovered PTP clock. When these
packets are received by nodes in the network, the
timestamping information can be mirrored onto monitoring
tools to identify network bottlenecks that cause latency.
This analysis can also be used for legal and compliance
purposes in institutions such as financial trading, video
streaming and research establishments.
