router

Physical network router sense

Record evidence for the provisional network-device interpretation and any existing canonical model that already owns it.

1. Does the registry source identify an IP packet-routing device, a woodworking tool or another sense? definition
2. Does an existing world model already cover this precise sense and therefore require a link rather than another publication? boundary

Routing capability versus appliance label

Describe what establishes routing capability and which integrated functions need neighbouring models.

1. What evidence shows that the device can select next hops and forward packets between IP networks? definition
2. Which switching, wireless, modem, NAT or firewall functions are integrated, and which remain active when routing is disabled? boundary

Port and media compatibility

Associate each interface type with connection requirements and operating evidence.

1. Which connectors, media, transceivers and link standards are supported, and which issuing bodies and specification versions establish compatibility? provenance
2. What link rate, duplex mode where applicable, error counts and flap history are observed on each active connection? measurement

Addressing and packet-size boundaries

Record logical attachments and the constraints they impose on reachability.

1. How are addresses, prefixes, VLAN subinterfaces and tunnel endpoints assigned to physical interfaces and routing contexts? boundary
2. What interface and effective tunnel MTUs apply in bytes, and what evidence establishes behaviour for oversized packets? measurement

Route authority and preference

Identify route sources, selection policy and the evidence supporting preferred paths.

1. Which routes originate from connected networks, static configuration or named routing peers, and what establishes their intended authority? provenance
2. How do prefix matching, route preference, protocol metrics and policy-based routing interact for the traffic being assessed? definition

Installed path and failure response

Tie route decisions to observed packet delivery and bounded disruption.

1. Do forwarding entries, next-hop neighbour resolution, counters and packet observations agree with the selected route? measurement
2. How can an authorised path-withdrawal or failover test measure convergence time and packet loss while preserving recovery access? action

Isolation, filtering and translation

Record supported policy mechanisms without assuming all routers provide stateful firewalling or NAT.

1. Which routing contexts, route leaks and ingress or egress policies determine the permitted source-to-destination paths? boundary
2. Where supported, how do filtering and address translation interact with route lookup, return paths and existing flow state? definition

Administrative and routing-control access

Identify who may administer the router and which networks or peers can reach its control services.

1. Which management services and routing adjacencies are reachable from each network, and what authentication and traffic restrictions apply? boundary
2. What authorisation, configuration comparison and alternate access are required before changing management or control-plane policy? action

Effective routing capacity

Record capacity evidence under explicit feature and workload conditions.

1. What throughput in bit/s and packets/s, latency and loss are supported by measurements with the intended packet sizes and enabled features? measurement
2. Which route, neighbour, queue or optional connection-state limits apply, and what observations reveal exhaustion, CPU overload or thermal throttling? measurement

Physical operating requirements

Identify the requirements specific to installing and servicing the applicable router class.

1. What dimensions, mounting clearances, input power and temperature limits apply, with units and manufacturer evidence? measurement
2. Which electrical, EMC and, if applicable, radio requirements and certification marks apply in the installation jurisdiction, and what maintenance or interlocks are documented? provenance

Software change and restoration

Establish whether configuration or firmware changes can be completed and recovered without losing essential access.

1. What evidence establishes firmware support status, update authenticity and compatibility with the installed hardware and configuration? provenance
2. What backup, console or out-of-band access, rollback method and post-change routing checks are required before an authorised update or reset? action
