Table with one row for each element of the type: 'IP multicast flow'.
Columns¶
| Name | Description |
|---|---|
| FTT. Worst blocked traffic (SRGs) | The SRGs where the worst case blocked traffic occurs, among the SRGs that this element has declared that it should be fault-tolerant to (the Fault-Tolerance-Target), calculated in the last risk analysis. This is the multicast flow blocked traffic (not injected since no path is found) averaged among the destinations, as a percentage (0...100) respect to the offered traffic |
| Statistical error | The statistical error associated with the accuracy of availability and survivability measures computed during analysis. |
| Description | A user-defined text description (potentially long) that can be assigned to this element |
| SRG groups | The names (comma-separated) of the SRG groups, for which this IP demand should be fault tolerant to. "All" stands for all the SRGs defined |
| Maximum E2 latency (ms) | The user-defined maximum acceptable end-to-end latency, from the origin node, to the destination node |
| Destination nodes | The set of destination nodes of the multicast flow. Cannot contain the origin node |
| Nodes not reached | Number of egress nodes that are receiving the traffic |

| Name | A user-defined name (typically short) that can be assigned to this element |
| FTT. Worst dropped traffic (SRGs) | The SRGs where the worst case dropped traffic occurs, among the SRGs that this element has declared that it should be fault-tolerant to (the Fault-Tolerance-Target), calculated in the last risk analysis.

| Any SRG. Worst latency (ms) | The worst case latency (ms) among all the SRGs (even if outside this element fault-tolerance target). For the latency computation, if the traffic follows different paths, the worst case among them is considered |
| Any SRG. Worst blocked traffic (SRGs) | The SRGs where the worst case blocked traffic occurs, among all the SRGs (even if outside this element fault-tolerance target), calculated in the last risk analysis. This is the multicast flow blocked traffic (not injected since no path is found) averaged among the destinations, as a percentage (0...100) respect to the offered traffic |

| Estimation relative error (%) | The relative error measured as the ratio between the absolute error, and the ground-truth traffic in this element |
| Availability | The estimated availability of this element, according to the last risk analysis computation, i.e. the expected fraction of the time in which this element is perfectly operating / being carried (i.e. 100% carried). This is a pessimistic computation. The optimistic one is this value, plus the error margin |
| Worst case e2e length (km) | The worst case length of traversed links in km (considering lower layer propagations), from the ingress node, to the egress nodes that receive the traffic |

| Origin node | The origin node of this multicast flow |
| Any SRG. Worst blocked traffic (%) | The worst case blocked traffic (%) among all the SRGs (even if outside this element fault-tolerance target), calculated in the last risk analysis.

| FTT. Worst blocked traffic (%) | The worst case blocked traffic (%) among the risk failures that this element has declared that it should be fault-tolerant to (the Fault-Tolerance-Target), calculated in the last risk analysis. This is the multicast flow blocked traffic (not injected since no path is found) averaged among the destinations, as a percentage (0...100) respect to the offered traffic |
| FTT. Worst dropped traffic (Gbps) | The worst case dropped traffic (Gbps) among the risk failures that this element has declared that it should be fault-tolerant to (the Fault-Tolerance-Target), calculated in the last risk analysis. Dropped traffic means traffic injected by the origin node, but dropped in one or more intermediate links, because of port congestion, or QoS violation |
| QoS class | The user-defined QoS class name for this IP multicast flow |
| Worst case e2e latency (ms) | The worst case latency in ms, from the ingress node, to the egress nodes that receive the traffic |
| FTT. Worst latency (ms) | The worst case latency (ms) among the risk failures that this element has declared that it should be fault-tolerant to (the Fault-Tolerance-Target). For the latency computation, if the traffic follows different paths, the worst case among them is considered |
| Total link BW consumed (Gbps) | The link bandwidth consumed summing all the links carrying traffic of this flow |
| QoS overs. | The amount of traffic in the demand that is violating the QoS in a traversing link. If this happens in several links, the maximum capacity outside the QoS assignment |
| Type of multicast flow | The type of multicast flow. Options are RPF-based and Statically routed. See the IP multicast simulation section for more details |
| Any SRG. Worst dropped traffic (SRGs) | The SRGs where the worst case dropped traffic occurs, among all the SRGs (even if outside this element fault-tolerance target), calculated in the last risk analysis. Dropped traffic means traffic injected by the origin node, but dropped in one or more intermediate links, because of port congestion, or QoS violation |
| NF. Blocked traffic (%) | The no failure blocked traffic (%) calculated in the last risk analysis. This is the multicast flow blocked traffic (not injected since no path is found) averaged among the destinations, as a percentage (0...100) respect to the offered traffic. |
| NF. Latency (ms) | The no failure latency in ms in the worst case, i.e. if the traffic follows different paths, the worst case among them is considered |
| Survivability | The estimated survivability of this element demand, according to the last risk analysis computation, i.e. the expected fraction of the demand traffic that will be correctly carried, considering the potential failures, their occurrence probability, and the fraction of traffic that survives in each failure. The optimistic value is this value, minus the error margin. Note that survivability values are always higher than availability ones, since in availability computations, any state in which less than 100% of the traffic is carried, sums as not unavailable time. |
