Once the student size is 10,000, the dormitories are fully wireless and three operators are connected simultaneously, any undeveloped campus network NATSHEL_AUTH_BILLING system will be rapidly magnified at peaks.
The problem never comes up.“Is there a way out?”And it's about:
The system has a unified and controlled capability across exports, operators and links.
And that is precisely what the cloud-based campus network Authentication & Billing system can do for long.
I. Multi-export, multi-operator does not really bring bandwidth but complexity
In a real university environment, multiple exports and operators mean:
-
Multiple physical links
-
Public network exports of different quality, varying stability
-
Operator side of different certification mechanisms, heartbeat mechanisms
-
Export combinations of different campuses, different regions
Students are represented in a single campus network portal.
This requires that the campus network Authentication & Billing system do three things simultaneously:
-
Send authentication requests without stacking
-
The billing session is not interrupted by changes in exports
-
Operators are abnormally not zooming in on their students.
These three points are virtually impossible to establish simultaneously under local deployment patterns.
II. Why the local deployment suffered from natural losses in a multi-export environment
The usual structures in the locally deployed campus network Authentication & Billing system are:
-
A set of Authentication & Billing logic for each export
-
The billing session is tied to the exit.
-
Export abnormally directly affects user status
The structure is maintained when the pressure is low; however, once the peak of the dormitories reaches, a typical problem arises:
-
Some operator's chain vibrating. → A lot of users were misjudged to be downline.
-
Export Switch → Rebuild fee session
-
Multiple exits and distribution → Local CPU/ IO fills in instantaneous time
-
Users at different exits“Repeatedly up and down line”
These problems are essentially due to one single cause:
System“Exports”It is a central node for billing and authentication.
iii. Campus network for cloud-based deployments Authentication & Billing system, in-kind decoupling exports
The cloud-based campus network Authentication & Billing system has done a very crucial thing in its structure:
Take it.“Exports”Remove it from the core of the system.
Under this structure:
-
Exports are only for transmission and execution.
-
Authentication logic in clouds
-
The billing engine is on the cloud.
-
User Sessions and Exports are completely decoupled
In other words, within the system:
-
User-on-line ≠ A dial-up of an exit has been successful.
-
User billing ≠ Tie a physical link.
-
Export Switch ≠ User offline
This step is a prerequisite for addressing the simultaneous pressures of multiple exports.
IV. How cloudy clouds can be harmonized to carry multi-export and issue certification requests
In a multi-export environment, real co-exist pressures are concentrated at two points of time:
-
Centralized accreditation for the peak period of accommodation
-
The surge of exits after an anomaly
The cloud-based campus network Authentication & Billing system will be designed to:
-
Authentication request centralized into cloud scheduler level
All export certification requests are logically entered into the same certification pool, rather than dispersed across the various exported equipment. -
Issuance of accreditation horizontal extension
Clouds can expand the authentication processing capability as required to avoid forming at an export node“Request avalanche.”。 -
Authentication and access decoupling
Even if an export responded slowly, it would not slow down the certification capacity of the entire system.
The blogger also writes about the fact that the government is not in a position to do so, and that is why many operators are doing it.The cloud-based campus network Authentication & Billing system is more stable.。
V. What's the most feared thing about a billing system when multiple operators combine?
In multi-operator environments, the most important thing about a billing system is not“There's not enough bandwidth.”But:
-
The session state is chaotic.
-
Duplicate
-
Offline error
-
Accumulation of dirty accounts
The cloud-based campus network Authentication & Billing system, usually follows:
-
Unified Session ID(Not relevant to export)
-
Cloud State Machine Manager Online Status
-
The exit is just a report, not a judgment.
The direct result of this is:
-
User on-line at operator A exit
-
Export to Operator B
-
User billing session is not over
-
No interruptions, no recosting
This is extremely difficult for local deployment systems.
VI. How are clouds when the exits are unusual?“Absorption of shocks”
In a real university environment, exports are the norm rather than the exception:
-
Operator maintenance
-
The cable shakes.
-
Urban area network congestion
-
PPOE failed
The cloud-based campus network Authentication & Billing system will put this anomaly in the air.“Inspire in the system.”：
-
Export anomaly → Cloud perception
-
Clouds Reconciling Export Strategies
-
User-side authentication status unchanged
-
The billing session will continue.
For students, it is often a brief network shaking rather than extensive disconnection or recertification.
VII. THE PRACTICALITY OF MILLENNIUM, MEDIUM EXPORT CORPORATION
When universities enter the multi-school cycle, the problem of multiple exports is further magnified:
-
Main campus, 3rd exit.
-
Two exits from the campus.
-
Different campuses use different operators
The cloud-based campus network Authentication & Billing system can:
-
Unified strategy for multi-school export
-
Independence in different campuses
-
Uniform rules on costing
-
Tier-level management privileges
There's only one logic at the system level, not one.“One system per campus”。
VIII. NatShell TRAD ON MOTE AND DESIGNING
In the NATSHEL_BRAND campus network Authentication & Billing system, multiple exports and multi-operators are not“Special scene”, but default operating environment:
-
Core authentication and billing cloud concentration
-
Export node destated
-
The session is not tied.
-
The strategy is sent from the cloud.
This makes the system face:
-
Hostel peak period
-
Large-scale and online.
-
Multi-operator switch
At times, it can still be maintained in a stable and long-term manner.
IX. A PRODUCT-only QUALITY QUESTION
In the university network:
The nature of the multi-export, multi-operator and pressure.
It's not about bandwidth.
It is about the structure of the Authentication & Billing system on campus.
Cloud deployment, on the other hand, is currently the only structural option that has been validated by a large number of real-school environments and can carry this complexity over time.
