  • Detail
  • Parameters

Agile Controller-WAN is a core component of the SDN WAN solution. It is designed for WAN (IP CORE) scenarios, DCI scenarios, and Cloud VPN scenarios. This enables fast deployment and delivery of VPN services in the WAN, simplifies the current network, Existing network operating costs.

Key Features

  • Service On-demand: Supports the automatic deployment of application-based network services on demand, shortens the service on-line cycle, improves service deployment efficiency, and supports service creation to automatically create tunnels based on user requirements and BOD / bandwidth calendars.

    Network Tuning: Supports BGP-LS-based network topology collection and path calculation. It supports traffic policing based on user policies and real-time network traffic to ensure high-priority service SLAs, improve bandwidth utilization and reduce network expansion costs.

    Carrier-class reliability: support for cluster and off-site disaster recovery.

    Visualization: Provides a global view of network / service path / service status for easy monitoring, management, and planning. Provides GUI interface for ease of use and locatability. Supports GUI configuration deployments for single NEs that can be performed on the controller. Single-station centralized configuration.

    Open innovation: support network business programmable. North to support the standard RESTCONF interface, through the open network capacity to accelerate network innovation, help operators operating efficiency. Support ONOS North to the standard interface, compatible with ONOS native APP.

    E2E Automated service provisioning and visualization

    Agile Controller-WAN enables automated deployment of application-based network services on demand.

    In a WAN scenario, Agile Controller-WAN provides the following features:

    Support L3VPN / VLL / Tunnel service management, including automatic GUI interface-based release and maintenance, business path and the status of the visual presentation.

    Support L3VPN / VLL bandwidth calendar and BOD.

    In a DCI scenario, Agile Controller-WAN provides the following functions:

    Underlay: L3VPN services that support VLAN access are automatically distributed to enable network connectivity between DCs.

    Overlay: Supports the automatic release of L3VPN services based on DSCP access, and supports the automatic classification of traffic classification policies into TE tunnels.

    In a CloudVPN scenario, Agile Controller-WAN provides the following features:

    Support Enterprise Site Through Thick CPE Layer 2 VXLAN dedicated line bearer, VXLAN leased line for PeerList way.

    Supports Cloud GW and DC L3 GW to connect through VLAN.


    Traffic Tuning Based on

    Traditional MPLS network, there are three main problems: planning and deployment of complex, bandwidth utilization is difficult to achieve optimal, complex network maintenance. To solve these problems, Huawei introduced the PCE + technology to manage the MPLS TE network through the PCE Server. The network resources are optimally used and the service differentiation is taken into account. This ensures that the priority services meet the requirements of high-priority services. .

    In the PCE + application scenario, the Agile Controller-WAN mainly implements the calculation of the total network end-to-end for the intra-area MPLS TE tunnel based on the user-inputted tuning policy, the network topology information collected by BGP-LS and the current traffic information collected by uTraffic And optimizes the MPLS TE route to improve the network bandwidth resource utilization rate.

    Tunnel management

    Tunnel management is mainly for the upper business services, the upper business needs of the tunnel management. Including the provision of application modules for the tunnel, the release of tunnels, and delete, query the tunnel service interface, the completion of the tunnel storage, and business-to-tunnel iterations. You can also query, create, modify, and delete tunnels through the UI interface.

    Topology management

    Network topology collection is the prerequisite for centralized control and calculation of Agile Controller-WAN. It is also the basis for resource management and tunnel management.

    Currently, there are two types of network topology information collected by the Agile Controller-WAN: physical topology information and logical topology information, and provides the global appearance of the topology.

    Physical Topology: Collects the LLDP database and neighbor information of the forwarders through the NETCONF protocol / SNMP protocol to obtain the physical topology.

    L3 Topology: Collects IS-IS-TE topology information through the BGP-LS protocol.
