Today, the digital wave has swept the world, and campus networks have become an important infrastructure for teaching, research, and management. However, with students, faculty, and visitors’ demands for the network surge, traditional web-management models are increasingly exposed to such painful points as confusion in bandwidth distribution, single billing, and equipment compatibility.
I. PPOE NATHELL_AUTH_BILLING System: campus network management“The heart of wisdom.”
The PPPOPE (Point-to-Point Production over Earthnet) technology has achieved a deep convergence of user identification, dynamic IP distribution and flow billing by encapsulating the PPP protocol in an Ethernet frame. NATSHEL_BRAND system is further innovative on this basis, combining the PPPOE with Radius agreement, cloud management platform to build a certification system that covers wire/wireless amphibious networks.
Typical application scenario:
(a) Student accommodations: to support online charging, purchase of traffic packages and avoid misuse of resources by running or long-term fees;
(b) Teaching buildings: allocation of exclusive bandwidth for online courses, videoconferences and quality assurance;
Library/laboratory: equipment-level certification through MAC address binding to prevent illegal access;
Visitors ' network: multiple means of authentication, such as text message identification codes and two-dimensional code sweeps, which combine security with ease.
The deployment of the NatShell system at a university has resulted in a 72 per cent drop in the network complaints rate and an increase in student satisfaction to 95 per cent, while increasing annual revenues by over $2 million through differentiated fee-based models.
II. Technological breakthrough: 90% compatibility with mainstream equipment and breaking down the barriers to manufacturing
NATSHEL_BRAND breaks the closed nature of the traditional Authentication & Billing system, and allows seamless interface with 16 major manufacturers such as H3C, Naking, H3C, Cisco and others through standardized interface protocols and equipment-driven libraries. Both core exchanges, AC controllers and wireless APs can be rapidly integrated by:
(a) The Radius Console: support for standard Radius authentication, authorization, billing (AAA) processes that are compatible with depth of BRAS equipment such as Ma5200 from China and C300 from Central China;
SNMP equipment management: Automated detection of network topping changes through real-time monitoring of the equipment status via SNMP protocol;
OpenFlow Protocol Extension: For SDN networks, provide programming flow flow capability and effect dynamic QoS strategy adjustments.
Case: An international school using an asomer network of AC+H3C switches, NATSHEL_BRAND has reduced the time for certification response to within 50 ms by means of multiple Radius server load balancing technology, supporting 5,000+ terminals online at the same time.
III. Five core functions: defining new standards for campus networks
1. Flexible certification, experience upgrading
The system supports eight types of authentication, such as account passwords, text message identification codes, micro-mail public numbers and 2D code sweeps, and can be connected to a school ' s unified identity certification platform (e.g. CAS).
2. Smart counting, precision operation
A technical college has adopted a three-dimensional model of the flow, duration, bandwidth and supporting complex strategies such as step pricing, baskets, etc.“Basic flow free + G overcharge”The model increased the utilization of network resources by 40 per cent, while reducing the cost of transportation by 35 per cent.
3. Dynamic bandwidth, guaranteeing experience
The bandwidth is dynamically distributed based on user identity, time, type of application. For example:
The evenings are peaking at 20:00-22:00 for the online examination, automatically increasing the bandwidth of the teaching building to 100 Mbps;
High bandwidth applications such as P2P downloads and video streams are limited to speeds, which guarantee the smooth running of key business flows.
4. Cloud management platform, unified control
Through the NatShell cloud platform, schools can view data on network usage, user online numbers, traffic distribution, etc. in real time and send out a configuration strategy remotely.
5. Data analysis, driving decision-making
The system ' s big data analysis module generates user behavioral images, peak time predictions, equipment failure alerts, etc. For example, by analysing the pattern of student dormitory traffic, schools optimize bandwidth procurement strategies and save over millions of dollars annually in network construction costs.
IV. SECURITY COMPLEMENTATION: STRENGTHENING THE SCHOOL NETWORK LANAGE
The system strictly follows the requirements of regulations such as the Cybersecurity Act and Data Security Act, providing:
Data encryption: Encryption of authentication information, traffic logs using the AES-256 algorithm;
Audit trail: complete recording of user login times, IP addresses, access applications etc. and support retention for more than six months;
Compliance interface: Open standard API, which can be linked to existing school security systems (e.g., on-line behaviour management, firewalls).
Concluding remarks: Selecting NatShell to open the campus network wisdom age
From technology compatibility to functional innovation, from user experience to operational efficiency, NATSHEL_BRAND PPOE NATSHEL_AUTH_BILLING system is working on“Full equipment compatibility, full-scale coverage, life cycle management”The concept of the campus network is being redefined. At present, it serves over 300 higher education institutions throughout the country and serves as a model for upgrading the educational sector network.
