Hundreds of apartments, tenants, and if you break the Internet for half a day, the phone calls can blow."Zero Network Re-engineering"The contractor will not sign the contract unless he agrees.
The article makes it clear how the transition to old networks can be smooth when retrofitting, so as not to affect tenants ' access to the Internet.
I. DEFINITION OF THE CURRENT NETWORK
Before the ISPs enter, we'll find out what equipment is on the deck.
Three typical old scenes:
-
Pure 100-millimeter network: The equipment was used in a 100-mega exchange, a megalobe router for years and it was not up to date. This is a change of equipment but the modifications are phased out.
-
The old authentication system is still in use.: There was an old Authentication & Billing system that did not have enough functionality but was still running. This is a new and old system switch.
-
Networking chaos.: The network is a patchwork of equipment and there is no unified structure.
How fast can you judge?
The three words of the integrated commercial are clear:
- How many years has the network been working on? What models?
- Is there a Natshell system? What brand?
- Can you accept the break-off during the renovation? How long can it take?
Ask them all, and the remodeling programme will come out.
II. Three options for zero-connection
Option 1: Phased online (most commonly used)
• Applied scene: Pure 100-millimeter network upgrades, or old systems are not enough.
Remodeling: The apartment is divided into several areas, such as building A, building B and building C. The building A is first modified, the unit is cleared and the building B is then remodeled.
Advantages:
- Most tenants remained unaffected during the renovation
- The integrated firm can debug while adapting. The problem is very much more visible.
- A's under pressure. No complaints from all tenants at the same time.
Disadvantages:
- Long overall transformation cycle
- It takes a while for new and old systems to coexist.
Actual cases where the project was located:
A long apartment, originally in a 100-mega exchange, was upgraded by a gigabyte. The integrated firm splits the flat into three units and first transforms building A. When building A is replaced with new equipment, the tenant can access the Internet without complaint.
Option 2: Concurrent systems (old systems still in use)
• Applied scene: The old NATHHELL_AUTH_BILLING system is still running, but not functioning enough.
Remodeling: When the new system is deployed, it runs in parallel with the old system.
Advantages:
- Problem can quickly get back to the old system.
- Tenant can switch gradually and experience little change.
- The integrator has enough time to get the new system.
Disadvantages:
- Two systems coexist, with a double fee for authorization (if authorized by user count)
- I'm going to need an integrator to understand two systems at the same time.
Actual cases where the project was located:
One long-lease apartment had an old, old billing system, but the billing rules were too rigid. The first side didn't want to be out of network. The integrator put the new system on another server and then cut A's tenant into the new one.
Option 3: Temporary set-up of standby networks
• Applied scene: A request."Zero Network", but the modifications must be replaced
Remodeling: During the re-engineering of tenants, a simple network is temporarily installed for the tenant and will be switched back when the new system is online.
Advantages:
- Tenant can access the Internet during renovation, and no complaints are made.
- I.A. has enough time to renovate and not have to catch up on the schedule
Disadvantages:
- Cost of additional equipment required
- The backup network is not as good as the new system. The tenant's experience is a little short.
Actual cases where the project was located:
A staff dormitory."Zero Network Re-engineering"The integrated owner temporarily built a simple unwired router to cover the entire dormitory, allowing tenants access to the Internet during remodeling."The net's a little slow."No complaints were filed on the Internet.
III. Three things for the pre-reform integration firm
Event 1: Backup existing configuration
Whatever the re-engineering options, the first step of an integrated provider is to back up the existing network configuration.
What needs to be backed up:
- VLAN configuration, port configuration for switchboard
- Router router chart, firewall rules
- Tenant information, billing records of existing certification systems
Backup to:
- Network Configuration Export to File, Save Udow
- Tenant information, billing records exported to Excel and stored on A-Service
Why back up?
The remodel failed, or A decided not to. The ICs have to recover quickly. Without backup, the ICs are gonna pay for it.
Event 2: Testing the new system before retrofitting
The new equipment is on site and not directly online, but is tested in the laboratory environment.
Test what?
- Can the new device be activated? Is there a hardware problem?
- Can you simulate a certain number of tenants online? Is it not enough sex?
- Do the billing rules work?
How long?
At least 24 hours of testing, the model is used by tenants.
Event 3: Notification of tenants in advance
Tenant is notified well in advance before the renovation to avoid sudden break-ins and complaints.
Notification:
- Remodel time (e.g. 1 March 00:00-6)
- Affected areas (A, B)
- Projected recovery time
- Contact number (to whom the tenant has questions)
Method of notification:
- Bulletin board announcement
- Texting each room.
- Micro-Create Notification
IV. FACTUAL ISSUES AND APPROACHING DURING RELIEF
Question 1: Some tenants are not online.
Possible causes:
- Tenant equipment not reconfigured
- The new system is certified differently from the old one.
Approach:
- Prepare tenant profiles in advance
- Make sure to get a call from someone during the renovation and direct the tenants remotely.
Issue 2: Loss of billing records
Possible causes:
- The old system billing records are not exported.
- Failed to migrate data when the new system is docked
Approach:
- Remodify old system billing records
- Check the tenant balance when the new system is online. Manually adjust if not
Issue 3: The new system is inadequate
Possible causes:
- The combinations understated their output.
- The new device is not being debugled.
Approach:
- Maximum simultaneous test before modification
- Discovering performance deficiencies, rapid upgrade of equipment or optimization of configuration
When are you not recommending a piecemeal re-engineering?
Zero network re-engineering sounds wonderful, but there are cases where it is not recommended.
No cases of sporadic network breakout are recommended:
-
The existing network is too messy: the equipment is in a rather patchwork and there is no unified structure.
-
The budget is limited: more equipment, more work-time and less than adequate.
-
The integrated trader team is not sufficiently staffed: the piecemeal network renovation requires parallel work and there are insufficient staff to be vulnerable to error.
What do the integrator say to A?
In short, the cost of a zero-connection network is 30 to 50% higher and the work schedule is doubled. If A accepts a phased conversion, it will be cut off for 1 to 2 hours per building, with no more than a tenant's complaints.
VI. WHAT TO DO WHEN THE REFORM IS COMPLETED
Renovation is not the end. There are three things to do.
1. Training of AOs
When the new system is online, the integrated firm will train A to use it.
Training for what?
- How do you open accounts and stop accounts?
- How do we check the billing records, export the statements?
- How to handle the billing dispute.
2. One week of follow-up
After the remodeling, the integrated firm follows it for a week to see if there's any problem.
Follow what?
- How many complaints do tenants make?
- Is the billing record accurate or not?
- Is the system not enough?
3. Transfer of old systems
If the old system is still in use, the IRC will assist with the transfer of the first party.
Transfer of what:
- Tenant Information for Old System
- Recording of old system charges
- Hardware equipment for old systems
The long-lease apartment network billing system, which allows smooth transition from old to old network remodelling, is critical for the selection of adaptation programmes.
Phased access is most common and most tenants are not affected; old and new systems are in use in parallel; temporary back-up networks are suitable for the first side of the spectrum to require a zero-connection.
The pre-reform integrated operator will do three things: backup configuration, testing of the new system, and notification to tenants.
Zero network conversion is costly and long-term, with a significant reduction in costs if A can accept phased remodelling and one to two hours per building.
