IT and Network Solution (ITNS.NET SRL) provides advanced design and integration services at the Data Link Layer (Layer 2) — the vital bridge between the physical network and the IP routing plane. This is where optical infrastructure meets intelligent switching, creating a robust, secure, and redundant environment for data transport.
Based on client requirements and the preliminary project design from Layer 1, our specialists develop complete technical solutions for the active network — defining architecture, selecting hardware, and calculating both CAPEX and OPEX to ensure efficiency and scalability.
Our Layer 2 Expertise
The Data Link Layer is where performance and reliability take shape. ITNS.NET engineers build Layer 2 systems that deliver high availability, low latency, and optimal traffic management. Every network we design supports seamless evolution toward higher capacities (1G → 10G → 100G) while maintaining full service transparency.
Core Activities at Layer 2 include:
- Topology Design & Redundancy Planning: defining star, ring, or mesh architectures with fail-over protection (RSTP/MSTP, LACP, MLAG) and resilient backbone links.
- Active Equipment Selection & Budgeting: preparing technical specifications for switches, OLTs, GPON/XGS-PON platforms, and aggregation devices. We work with leading vendors including Juniper, Cisco, Huawei, Arista, Mikrotik, D-Link, TP-Link, and many others, while remaining ready to learn and integrate new technologies based on client needs.
- VLAN & QoS Architecture: segmentation of services using IEEE 802.1Q, 802.1ad, 802.1p; defining traffic prioritisation, multicast handling (IGMP snooping) and service profiles for triple-play delivery.
- Security & Access Control: implementing authentication, MAC filtering, storm-control, and loop detection to ensure stable operation in multi-tenant and provider environments.
- Management & Monitoring Framework: integrating SNMP, Syslog, NetFlow and centralised NMS systems for real-time visibility and performance reporting.
- Documentation & Handover: producing complete Layer 2 schematics, device configuration templates, addressing plans and as-built drawings for client approval.
Design and Budgeting Process
Each Layer 2 project begins with a technical and financial assessment. We analyse expected traffic loads, service profiles (Internet, IPTV, VoIP), redundancy requirements and growth potential. Using vendor-neutral planning tools, we generate an optimised equipment list and cost model to ensure that capital investments produce maximum network performance and minimal operational expenses.
The result is a precisely engineered, ready-to-implement Layer 2 solution that forms the foundation for reliable routing and service delivery at Layer 3 and beyond.
Intelligent network design starts at Layer 2 — ITNS.NET creates the switching infrastructure that keeps Moldova connected and future-ready. Talk to our network architects
