Columns¶
| Name | Description |
|---|---|
| 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 |
| Attributes | User-defined attributes associated to this element |
| SRGs | The Shared Risk Groups (SRGs) this element belongs to: the SRGs that mandate the shutdown (set in failure state) of this element |
| TAPI uuid | TAPI global uuid json object |
| Name | A user-defined name (typically short) that can be assigned to this element |
| Identifier | A unique identifier set to the element, and never changed |
| Length (km) | The length in km that traverses the traffic of this element, considering the paths followed in the underlying physical transport connections. The value provided is the worst case length: all the paths of this element in the underlying infrastructure are analyzed. More than one path can occur e.g. if 1+1 bifurcations appear at lower layers carrying this element |
| IP port (B) | Attached IP port in link destination |
| 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 |
| FTT. Worst latency (SRGs) | The SRGs where the worst case latency 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. |
| Tags | User-defined tags associated to 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 |
| Intra-node | Indicates if both end nodes are the same or not |
| Bidi pair | If this element is bidirectional, contains its bidirectional pair |
| NF. Blocked traffic (Gbps) | The no failure blocked traffic (Gbps) calculated in the last risk analysis. Blocked traffic means that the connection is not setup, because no path was found |
| JSON | An optional JSON content describing this element |
| TAPI Local uuid | TAPI local UUID. This means, local respet to belonging TAPI element |
| Up | Indicates if the element is up (active) or down (failed) |
| IP traffic (Gbps) | The IP traffic (Gbps) carried in this ODU |
| 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 |
| A | Origin node |
| B | Destination node |
| 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. Blocked traffic means that the connection is not setup, because no path was found |
| Statistical error | The statistical error estimated in the availability and survivability computations |
| Description | A user-defined text description (potentially long) that can be assigned to this element |
| Nominal capacity (Gbps) | The nominal capacity of this element in Gbps |
| ODU recovery type | The type of recovery scheme to be applied to this ODU |
| Any SRG. Worst blocked traffic (Gbps) | The worst case blocked traffic (Gbps) among all the SRGs (even if outside this element fault-tolerance target), calculated in the last risk analysis. Blocked traffic means that the connection is not setup, because no path was found |
| Working path | The working path of this connection, i.e. the sequence of lower layer links traversed. It appears in red if there is no working path, indicating that this connection is blocked. In yellow, if there is a working path coming from a successful restoration, i.e. the nominal path/s are all down, but this element is tagged as restorable, and a valid restoration path in the surviving topology was found |
| CEP B | TAPI connection-edge-point in the link destination |
| Transversing IP Links | The list of the transversing IP links for this ODU/DSR. |
| NEP A | TAPI node-edge-point in the link origin |
| CEP A | TAPI connection-edge-point in the link origin |
| NEP B | TAPI node-edge-point in the link destination |
| FTT. Worst blocked traffic (Gbps) | The worst case blocked 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. Blocked traffic means that the connection is not setup, because no path was found |
| ODU/DSR type | Indicates if this circuit is an ODU, or a DSR signal directly transmitted in the OTU |
| Latency (ms) | The latency in miliseconds suffered by the traffic of this element, considering the paths followed in the underlying physical transport connections. The value provided is the worst case length: all the paths of this element in the underlying infrastructure are analyzed. More than one path can occur e.g. if 1+1 bifurcations appear at lower layers carrying this element |
| Any SRG. Worst latency (SRGs) | The SRGs where the worst case latency occurs, among all the SRGs (even if outside this element fault-tolerance target), calculated in the last risk analysis. |
| 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. Blocked traffic means that the connection is not setup, because no path was found |
| External links | Indicates if this element has one or more user-defined external URLs associated to it. If so, when the user clicks this cell, and selects the URL (if more than one), a navigator is launched and the URL page is shown. External links are not editable in the GUI, but via API. |
| Hit option rule | The design option matching this element. If no design option is matched, it is assumed that the element is not confirming the design rules |
| FT SRGs | The SRGs to which this IP demand should be fault tolerant to |
| TAPI JSON | Full TAPI JSON for this element |
| Nominal paths | List of nominal paths defined |
| 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 |
| IP port (A) | Attached IP port in link origin |
| Installed | Indicates if the element is installed. If not installed, the element behaves as if it did not exist, being unable to e.g. handle traffic or reserve any bandwidth |
| Path info | A string informing on the path that this element is following |
| 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. |
