Network Architecture & Design
Networks designed for yesterday's requirements create bottlenecks, security gaps, and costly change cycles as cloud and hybrid workloads scale.
Our Approach
Design modern, secure, and resilient network foundations — topology, routing, segmentation, and operations — aligned to your actual traffic patterns and business risk.
What This Service Covers
Network architecture consulting for organizations that need a design that is secure, operable, and built for where the business is going — not just where it is today.
Engagements span enterprise LAN/WAN redesigns, service provider access and backbone design, data centre fabric, SD-WAN rollouts, cloud on-ramp connectivity (AWS Direct Connect, Azure ExpressRoute, GCP Interconnect), and BGP policy design for multi-homed or transit environments.
Scope areas
Topology and routing design Campus, branch, DC core, and inter-region routing. BGP policy, route reflectors, traffic engineering, and failure-mode planning. SP-grade designs including MPLS, SR-MPLS, and segment routing.
Security segmentation Zone-based segmentation, macro and micro-segmentation, VLAN and VRF strategy, firewall placement, and east-west traffic control. Designed to support zero-trust initiatives and audit requirements.
Service provider and IP backbone SP-grade BGP design — route reflectors, communities, policy, and multi-homing. MPLS and MPLS VPN (L2/L3 VPN) design. Segment routing (SR-MPLS, SRv6). National and metro backbone capacity planning. IP backbone operations and incident management experience across Vodafone and Tata Communications environments.
Cloud and hybrid connectivity Private connectivity to AWS, Azure, GCP. IPSec and MPLS hybrid designs. Routing policy between on-prem and cloud. SD-WAN overlay design with cloud breakout. Aviatrix multi-cloud network design and transit architecture.
Operational design Change management patterns, automation opportunities (Ansible, Netconf/Yang, Python), monitoring and alerting baselines, and runbook templates for common failure scenarios.
Delivery Models
Remote Consultation
Structured advisory calls — architecture review, design decision support, vendor evaluation, or problem diagnosis. Typically half-day or full-day blocks. Deliverable: written findings or design notes after each session.
Remote Support Retainer
Monthly hours block for ongoing advisory — change review board participation, pre-change design checks, configuration review, and escalation support. Best for teams without a dedicated network architect.
Engineer Basis (Project)
Fixed-scope design engagement: assess current state, produce target-state architecture, deliver migration plan and runbooks. Remote-led with your team executing on-site. Typical scope: 2–6 weeks depending on complexity.
Typical Engagement Formats
| Format | Best for | Typical Duration |
|---|---|---|
| Architecture Review | Validate an existing design or identify gaps | 1–3 days |
| Greenfield Design | New DC, campus, or cloud connectivity | 3–6 weeks |
| Migration Planning | Replacing legacy gear or re-segmenting | 2–4 weeks |
| Retainer Advisory | Ongoing design support for the ops team | Monthly |
