LAN, WAN, SD-WAN & Managed Connectivity
One enterprise network fabric across every branch, data centre and cloud.
Jiva Technologies consults, designs, deploys, integrates and supports enterprise LAN, WAN and SD-WAN — campus and branch switching, spine-leaf data-centre fabrics with EVPN-VXLAN, application-aware SD-WAN overlays, BGP / OSPF / MPLS routing, QoS, high availability and hyperscaler connectivity — as a multi-vendor lifecycle service.
Cisco, Juniper, HPE Aruba, Fortinet, Palo Alto, Arista, Extreme, VMware and Cato.
Broadband, MPLS, dark fibre, LTE, 5G and hyperscaler direct-connect.
Assessment, design, supply, deployment, integration and managed operations.
What we deliver
Application-Aware SD-WAN
Design, deploy and operate SD-WAN overlays across broadband, MPLS, dark fibre, LTE and 5G — with dynamic path selection, per-app QoS and centralised policy on Cisco Catalyst SD-WAN, Fortinet Secure SD-WAN, Palo Alto Prisma SD-WAN, VMware VeloCloud, HPE Aruba EdgeConnect, Versa Networks and Cato Networks. Improves SaaS and unified-communications performance and enables direct-to-cloud paths for hybrid work.
Campus & Branch Switching
High-density campus and branch access layers with 802.1X, NAC, dynamic segmentation, LACP, redundant uplinks and PoE for wireless, IoT and surveillance — engineered on Cisco Catalyst / Meraki, HPE Aruba CX, Juniper EX / Mist, Extreme Networks and FortiSwitch. Delivers deterministic performance and simplified operations across every site.
Data-Centre Spine-Leaf Fabrics (EVPN-VXLAN)
Modern spine-leaf data-centre networks built on Cisco Nexus, Juniper Apstra, HPE Aruba CX or Arista EOS with EVPN-VXLAN, multi-tenancy, micro-segmentation and integration to VMware NSX and Kubernetes CNI. Scales east-west traffic and supports hybrid connectivity through Azure ExpressRoute, AWS Direct Connect and Google Cloud Interconnect.
Enterprise Routing (BGP, OSPF, MPLS)
Multi-site enterprise routing design and operations — BGP peering, OSPF, MPLS L3VPN, route summarisation, traffic engineering, ACLs and clean SD-WAN interoperability. Provides deterministic path selection, high availability and predictable service delivery for critical business applications.
High Availability & Network Resilience
Redundant core, distribution and edge design — HSRP / VRRP, MC-LAG, dual power, dual control planes and dual-ISP internet edge with carrier diversity. Reduces single points of failure across campus, branch and data-centre networks.
QoS, WAN Optimisation & Hybrid WAN
Application prioritisation, traffic shaping, TCP acceleration and hybrid WAN design combining MPLS, internet and cellular — so ERP, VoIP, contact-centre and video traffic remain predictable across constrained or long-haul links.
Cloud & Hyperscaler Networking
Extend enterprise networks into Microsoft Azure, AWS and Google Cloud with landing-zone networking, transit gateways / hubs, VNet / VPC peering, direct-connect and secure egress — integrated with SD-WAN and SASE for consistent policy across on-premises and cloud.
Consulting, Integration & Managed Networking
End-to-end lifecycle services: consulting, architecture, procurement, deployment, integration, migration, optimisation and NOC-managed operations under an agreed service schedule — with multi-vendor design authority across every layer of the enterprise network.
Why teams call us
- Legacy WAN cannot keep up with SaaS and hybrid work
Static hub-and-spoke MPLS designs backhaul cloud traffic through central sites, adding latency for Microsoft 365, Teams, contact-centre and video applications.
- Inconsistent standards across sites
Branch, campus and data-centre networks were built by different teams and vendors at different times, leaving configuration drift, mixed platforms and undocumented exceptions.
- Limited resilience at the internet edge
Single-carrier internet, single control planes and unmanaged failover mean an ISP or hardware event takes critical sites offline until a manual intervention.
- Cloud and data-centre traffic patterns have shifted
East-west traffic, container platforms and hyperscaler workloads have outgrown three-tier data-centre designs, creating oversubscription and long troubleshooting cycles.
Our approach
A multi-vendor lifecycle covering assessment, target-state design, phased implementation and ongoing operations for the enterprise network fabric.
- Assess
Review current LAN, WAN and data-centre topology, transport contracts, application traffic patterns, resilience posture and operational tooling.
- Design
Produce a multi-vendor target architecture covering routing, switching, SD-WAN overlay, QoS, resilience, cloud connectivity and phased migration waves.
- Implement
Deploy, configure, integrate and migrate with dual-run cutovers, identity and observability wired in from day one, and evidence-based acceptance testing.
- Operate & Optimise
Support the network under an agreed schedule with configuration hygiene, capacity reviews, incident coordination and periodic performance reporting.

Fix What's Broken — Remediation Sprints
Wi-Fi dead zones, WAN performance issues, SD-WAN policy drift, or a network you can't see into during incidents? We run fixed-scope networking remediation sprints against a defined outcome.
- LAN/WLAN survey, controller tuning and coverage/roaming fixes
- SD-WAN, MPLS and internet-breakout policy cleanup and QoS tuning
- Observability rollout: flow, telemetry, path-analytics and alert hygiene
Support & Maintenance — AMC-Backed
Keep the network reliable after go-live — firmware, controller hygiene, ISP coordination and vendor-TAC escalation under a Jiva AMC or managed connectivity service.
- L1/L2/L3 support for LAN, Wi-Fi, WAN, SD-WAN and network observability platforms
- Preventive maintenance, firmware and ISP/carrier coordination with SLAs
- Vendor-TAC escalation, licence renewal and network lifecycle refresh
