Post-deployment connectivity and performance testing results

Quick answer
What is Post-Deployment Network Connectivity and Performance Testing?
Post-deployment network testing is a documented set of measurements taken after installation to prove that links, routing, redundancy, and applications work against agreed acceptance criteria. Deploris engineers run the tests on site, record the results with timestamps and screenshots, and give you pass or fail evidence for every item in scope.
WHAT THE WORK COVERS
What Post-Deployment Network Connectivity and Performance Testing includes.
- 01Link-level checks of negotiated speed and duplex, optic receive power, CRC and error counters, and PoE budget on the ports in scope
- 02Layer 2 and layer 3 verification of VLAN reachability, spanning tree state, routing adjacencies, default gateway behavior, and path MTU
- 03Throughput testing with iPerf between agreed endpoints, plus latency, jitter, and packet loss measurements over a defined duration
- 04Failover tests for redundant uplinks, stacked members, HA firewalls, and dual WAN circuits, with recovery times recorded
- 05VPN, DNS, DHCP, and authentication checks (802.1X or RADIUS) from a test client on each relevant VLAN
- 06Application-level tests chosen with you, such as reaching a line-of-business system or placing a test VoIP call
- 07A results sheet that compares every measurement to your acceptance criteria, with evidence attached
HOW WE DELIVER IT
How it is delivered.
- 1
Agree acceptance criteria
Before work starts, we write down what will be tested, between which endpoints, with which tools, and what values count as a pass, using your standards where you have them.
- 2
Baseline before changes
Where the old network still exists, we capture a baseline first so the new results can be compared with real numbers instead of assumptions.
- 3
Test after installation
Once devices are live, the engineer runs the test plan from wired and wireless test points, repeating any failed item after correction and logging both results.
- 4
Report the evidence
You receive the results sheet and supporting screenshots, exported logs, and notes on any item that missed its criteria, along with what was done about it.
INPUTS AND OUTPUTS
What you provide and what you receive.
You provide
- Acceptance criteria, or a service level target that we can convert into test thresholds
- Test endpoints, such as a server or iPerf host, and the applications you want checked
- Access to a representative client VLAN, user account, and any authentication servers required
- A time window when the network can carry test traffic without disturbing production users
You receive
- A results sheet with measured values, pass or fail status, and timestamps for each test
- Supporting screenshots, logs, and iPerf or ping output exported from the test session
- Failover and recovery test records for each redundant component in scope
- A list of items that missed their criteria, with the corrective action and retest result
WHEN IT FITS
When this is the right deliverable.
A contractor or vendor says the new network is finished and your team wants independent evidence before accepting the work and releasing payment.
You are migrating a site off an old network and need proof that performance is at least equal to the baseline before the old equipment is decommissioned.
A critical branch application, such as POS or telemedicine, depends on specific latency and loss limits, and you want those limits verified at go-live.
