link so that the remote gateway can slow its transmission of data. The PAUSE control is in full
compliance with industry standard IEEE 802.3z.
Point to Point Topology
Two S-2500B Gateways are directly connected via a SONET network in a point-to-point
connection. This topology provides the highest performance, since the full bandwidth of the
SONET link is dedicated to the Gateway SAN extension.
