  • Page 26: Fcip Circuit Failover Capabilities

    FCIP trunking • In a scenario where a FCIP tunnel has multiple circuits of different metrics, circuits with higher metrics are treated as standby circuits, and are not used until all lower metric circuits fail. Refer to “FCIP circuit failover capabilities” for a more detailed description.

  • Page 27: Bandwidth Calculation During Failover

    FCIP trunking Figure 6, circuit 1 is assigned a metric of 0, and circuit 2 is assigned a metric of 1. Both circuits are in the same FCIP tunnel. In this case, circuit 2 is a standby that is not used unless there are no lowest metric circuits available.

  • Page 28: Adaptive Rate Limiting

    Adaptive Rate Limiting Adaptive Rate Limiting Adaptive Rate Limiting (ARL) is performed on FCIP tunnel circuits to change the rate in which the FCIP tunnel transmits data through the IP network. ARL uses information from the TCP connections to determine and adjust the rate limit for the FCIP circuit dynamically. This allows FCIP connections to utilize the maximum available bandwidth while providing a minimum bandwidth guarantee.

  • Page 30: Qos, Dscp, And Vlans

    QOS, DSCP, and VLANs QOS, DSCP, and VLANs Quality of Service (QoS) refers to policies for handling differences in data traffic. These policies are based on data characteristics and delivery requirements. For example, ordinary data traffic is tolerant of delays and dropped packets, but voice and video data are not. QoS policies provide a framework for accommodating these differences in data as it passes through a network.
