  • Page 34: Frame Buffering And Latency

    ® BLACK BOX Gigabit Media Converter Switch Installation & User Guide Frame Buffering and Latency The LBH2001A Series Converter Switches are store-and-forward switches. Each frame (or packet) is loaded into the Switch’s memory and inspected before forwarding can occur. This technique ensures that all forwarded frames are of a valid length and have the correct CRC, i.e.
  • Page 35 ® BLACK BOX Gigabit Media Converter Switch Installation & User Guide memory pool, ensuring that heavily used ports receive very large buffer space for packet storage. (Many other switches have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed number of packets to be stored per port. When the port buffer fills up, dropped packets result.) This dynamic buffer allocation provides...
  • Page 36 ® BLACK BOX Gigabit Media Converter Switch Installation & User Guide Another feature implemented in LBH2001A Series Converter Switches is a collision-based flow-control mechanism (when operating at half-duplex only). When the Switch detects that its free buffer queue space is low, the Switch prevents more frames from entering by forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.
