Network Topology & Single Pane of Glass
OmniWeb's topology views are the "single pane of glass" entry point to the whole network. They show how the elements connect, which ones are deployed, and let you jump straight from a node on the map into that element's workspace.
Topology Views
The landing/topology page presents the network across four domain tabs. Each is an interactive map of the relevant elements and their interfaces.
EPC topology: UE → eNB → MME → SGW-C → PGW-C → UPF, with Diameter signalling through the DRA to the HSS. Active elements show a coloured border and an instance-count badge.
| Tab | Elements shown |
|---|---|
| Core (EPC) | UE → eNB → MME → SGW-C → PGW-C → UPF; DRA ↔ HSS; OCS; TWAG; RAN Monitor |
| IMS | P-CSCF → I-CSCF → S-CSCF; DRA ↔ HSS; TAS; IMS SMSc → SMSC → SMPP GW; OCS; Entitlement (OmniSEP) |
| CS Core | BTS → BSC → MSC; STP ↔ HLR / CAMEL GW / IP-SM-GW; HSS; SMSC; OCS |
| 5G Core | gNB → AMF → SMF → UPF; NRF, SCP, AUSF, UDM, UDR, PCF; CHF → OCS; NSSF; BSF |
Reading the Map
- Active elements — those with instances declared in
omniweb.json— appear with a coloured border and a badge showing how many instances exist. Clicking one opens a popover with direct links to each instance, so you can navigate from the topology straight into an element's pages. - Unconfigured elements appear greyed out, so the map doubles as a quick inventory of what is and isn't deployed.
- Connections indicate the interface between elements (e.g. SIP, Diameter, PFCP, GTP-C, SS7), distinguishing signalling types.
This makes the topology page the natural starting point: see the shape of the network, spot what's deployed, and drill in.
Element-Level Topology
Some elements also provide their own focused topology view. The PGW-C → Topology tab, for example, shows that node's relationships to its SGW-C, UPF, and Diameter peers, annotated with live session counts and utilisation — a localised single-pane view for that element's neighbourhood.
PGW-C topology: SGW-C, UPF, and Diameter peer relationships with per-peer session distribution.
Host List & Infrastructure
Beyond the network functions themselves, the Host List page is the single pane of glass for the infrastructure that runs them. It lists all infrastructure hosts by category, each with a direct link to its web UI:
| Category | Examples |
|---|---|
| Monitoring | Grafana, Prometheus, Loki |
| SIP Capture | Homer Web UI |
| Charging | OCS Web UI |
| DNS | DNS servers |
| Virtualisation | Proxmox hypervisor consoles |
| Out-of-band | iDRAC server management |
| Routers | MikroTik WebFig, Peplink |
| Microwave | SAF, Ubiquiti AirFiber links |
| NAS | Synology DSM |
The Host List — every infrastructure and element host by category, each with a direct link to its web UI (Grafana, Prometheus, Loki, element APIs, and more).
This gives operators one place to reach every supporting system — monitoring, hypervisors, out-of-band management, transport — without hunting for bookmarks.
