H3C AD-Campus Solution

Uniform network settings and policy enforcement across the network (UniformUX 2.0)

In a traditional campus network, the IP address of a client changes as the client location changes. If a client roams to another location in the same campus network, its IP address, applicable network policies, and applicable security policies also change. This requires complex network planning, configuration, and tests.

With UniformUX 1.0, the AD-Campus network separates network services from physical devices to decouple physical network and virtual network. It enables clients' resources (address, security, and isolated channel resources), network policies, and security policies to be retained after roaming, simplifying network maintenance and improving efficiency.

Based on UniformUX 1.0, UniformUX 2.0 introduces micro-segmentation and enables network decoupling, which can help users to upgrade networks to SDN networks with few changes on the live network.

Location decoupling—In traditional campus network solutions, services are tightly coupled with locations. Once the service location changes, the network needs to be adjusted. With services decoupled from the location, AD-Campus allows endpoints to move freely within the campus with stable services for which the network administrators do not need to perform any operations. This makes AD-Campus easy to use, flexible, and adaptable to the organization's changing network requirements. Also included in the location decoupling is the ability of AD-Campus to manage devices from multiple locations as well as the location of the AD-Campus platform that may span to multiple campuses.

Network decoupling—AD-Campus uses micro-segmentation to decouple roles from the network. All policies are deployed based on roles and role permissions are further classified, enabling role-based policy enforcement across campuses. This also enables service decoupling from networks and service isolation. Micro-segmentation assigns different permissions to users at the same location and allows a user to move around with the same permissions, IP address, and services.

One-click service deployment—AD-Campus provides default and allows customization of user policy templates. To deploy a service, you only need to drag and drop the policy template into the two-dimensional matrix. The service will then be deployed automatically without requiring you to execute any commands.

Role-based user behavior audit—In traditional campus networks, user behaviors are typically audited based on user's IP address. However, because user's address changes constantly when the user moves, it is difficult to audit the user based on the IP address. By implementing uniformed network settings across the network, AD-Campus binds the IP address to the user. No matter where the user moves, the IP address remains unchanged, enabling direct audit of users. AD-Campus is equipped to secure access control and data encryption to protect against unauthorized access and data breaches.

Fully automated

AD-Campus decouples configuration from devices, classifies devices across the network into four roles, and creates a configuration template for each device role. It enables automated device onboarding, automated service deployment, and automated faulty module replacement to provide ease of deployment, ease of scalability and rapid recovery from a failure. It also utilizes APIs for the automation and orchestration of network devices and services.

Automated device onboarding—AD-Campus classifies network-wide devices into four roles: spine, AGGR, leaf, and access, and uses the same configuration file for devices of the same role. It provides a configuration wizard which will guide you to create a configuration file without any command execution. It enables devices to load the configuration file automatically after they are powered on, greatly improving network deployment efficiency. OpenFlow, NetConf, RestConf and SNMP protocols are used for flexibility in network design and ensuring compatibility with a wide range of SDN-enabled devices.

Automated service deployment—Focusing on user services, AD-Campus orchestrates and allocates network resources flexibly to enable uniform network settings and enforcement of policies across the network. It abstracts the network to shield the underlying complexity and enables simple and efficient configuration and management at the upper layer. It defines main network virtual objects so users can easily and flexibly construct their business systems simply by dragging and dropping virtual objects.

Automated faulty module replacement—After devices are powered on, the system identifies the newly added devices (including new devices that replace the faulty devices) automatically, deploys configurations to the devices based on their roles, and then incorporates them. With a precise replacement workflow, the system can restore the existing configuration of the replaced devices completely on new devices.

Intelligent IoT

As IoT endpoints on campus networks grow exponentially in type and number, AD-Campus uses the intelligent IoT solution to enable fast and safe onboarding of IoT endpoints. When IoT endpoints start up, the intelligent IoT solution immediately identifies and onboards them and then automatically places them into isolated channels. In addition, this solution provides a flexible authentication policy. It can perform precise MAC-based authentication for endpoints with known MAC addresses and also allows fast onboarding of endpoints with unknown MAC addresses by using the authentication-free scheme.

AD-Campus innovatively introduces the Endpoints Profiling System (EPS) to perform compliance inspection on IoT endpoints. The EPS system is used mainly to identify and monitor endpoints across the network. The system scans all authenticated and non-authenticated endpoints with a scanner, accurately identifies the types of endpoints, provides baseline management of IoT endpoints, and detects abnormal endpoints in time. With EPS combined with the EIA endpoint access control system, AD-Campus provides all-round management of network access endpoints in high efficiency.

Unified management from multiple dimensions

Designed based on the cloud-native architecture, the AD-Campus solution provides unified management from multiple dimensions and can solve the issues existing in traditional campuses from multiple dimensions. AD-Campus dashboard is a single-pane-of-glass interface with a topology map that can provide network details such as health status, events, alarms, and other relevant information. This interface is centralized management and control of the network with a user-friendly interface for configuration, monitoring, and management of network devices, policies, and services. The topology map provides a traffic map that visualizes network utilization and bandwidth across all links including all the protocols used through the network and from the specific devices in real time. AD-Campus is equipped with centralized control plane that provides a unified view of the network topology and enable policy-based network management.

Unified management across multiple scenarios—AD-Campus can provide unified network control, orchestration, and management across multiple scenarios including the campus, data center, and WAN scenarios from one single management platform.

Unified management across multiple campuses—With the H3C multi-fabric solution, AD-Campus achieves unified management and control across multiple campuses and simplifies O&M. The multi-fabric solution can not only enable automated network deployment, unified policy configuration, and uniform policy enforcement across campuses, greatly reducing campus O&M complexity, but also enable local authentication, local forwarding, and regional autonomy to reduce inter-campus communication complexity and enable unchanged permissions for employees travelling across campuses. Hierarchical deployment can ensure high availability and fault tolerance to ensure continuous operation of the network even in the presence of hardware failures or software issues.

Network and security integration—AD-Campus innovatively introduces the service chain technology, and supports both east-west service chain and north-south service chain. Through traffic steering of service chains, AD-Campus achieves SDN automation from Layer 4 to Layer 7 and enables orchestration of network and security from the global perspective. Thanks to elastic service resources scalability in service chains and transparency of security device replacement to network devices, AD-Campus provides flexible and on-demand resource allocation as well as robust network protection.

Unified management of wired and wireless services—At the management level, AD-Campus uses one set of management systems and provides unified topology display, unified authentication, and unified user group division for wired and wireless services. At the policy level, wireless data forwarding is completely moved from the AC to the switch. The service policies defined through the policy matrix are completely applicable to both wired and wireless traffic, and you are not required to define inter-group policies separately for wireless traffic so as to realize unified wired and wireless policies.
