Network Infrastructure and Transmission Connectivity

Traditional Network Solutions (Core, Distribution, Access)

With extensive experience in deploying network infrastructure for large organizations such as banks, airports, and state-owned enterprises, ETC confidently delivers three-tier network solutions (Core – Distribution – Access) that meet stringent requirements for performance, security, and scalability.

Traditional Network Solutions (Core, Distribution, Access)

Key system features include:

  • Optimized three-tier architecture

    The Core layer handles high-speed traffic, the Distribution layer performs routing and access control, and the Access layer connects end users and endpoint devices.

  • Integrated network security

    Implements mechanisms such as ACLs, 802.1X, VLANs, DHCP Snooping, and more to ensure secure access and protect against internal threats.

  • Automation and centralized management

    Supports centralized monitoring, configuration, and automated deployment, helping reduce errors and operational costs.

  • Multi-protocol and virtualization support

    Compatible with OSPF, BGP, VRF, MPLS, VXLAN, and other technologies to enable flexible segmentation and routing.

  • Easy scalability and integration

    Ready to integrate with modern platforms such as SD-WAN, data centers, IoT environments, and digital transformation systems.

Software-Defined Networking (SDN) Solutions

ETC provides Software-Defined Networking (SDN) solutions that enable organizations to modernize their network infrastructure, enhance flexibility, increase automation, and optimize operations. With hands-on experience in deploying Cisco ACI—one of the world’s leading SDN platforms—for major customers such as VietinBank, Vietcombank, and ACV (Airports Corporation of Vietnam), ETC confidently delivers comprehensive SDN solutions tailored to the requirements of large-scale and complex systems.
Backed by a team of highly experienced experts with in-depth knowledge of Cisco ACI and other SDN platforms, ETC is committed to partnering with customers to build modern, secure, and flexible network infrastructures that meet the demands of digital transformation across the finance, transportation, and critical infrastructure sectors.

  • Centralized management with separation of control and data planes

    Centralized management with separation of control and data planes

    SDN architecture enables centralized network control instead of configuring individual devices separately, allowing flexible traffic orchestration and effective traffic management.

  • Automated configuration and deployment

    Automated configuration and deployment

    Enables application-based network policy definition and automatically distributes policies to devices without complex manual operations.

  • Zone-based security and microsegmentation

    Zone-based security and microsegmentation

    Supports policy-driven traffic isolation between applications, virtual machines, and users, minimizing the risk of lateral movement and internal attack propagation.

  • Seamless integration with virtualization and cloud infrastructure

    Seamless integration with virtualization and cloud infrastructure

    Compatible with platforms such as VMware, OpenStack, Kubernetes, and other modern infrastructure orchestration systems.

  • Real-time network monitoring, analytics, and optimization

    Real-time network monitoring, analytics, and optimization

    Provides comprehensive visibility into network operations, enabling anomaly detection and rapid incident response.
