Enterprise Connectivity

Enterprise connectivity, delivered end to end. GSS coordinates carriers, local loops, cross-border segments, CPE and on-site work under one design for DIA, IEPL, MPLS, IP-VPN and SD-WAN.

Enterprise Connectivity

Define the service level, design the path, then pick the bandwidth

Every segment has a demarcation point, a latency budget and a protection scheme. The topology is indicative and the tier table lists selectable service levels; the contracted order governs.

Enterprise connectivity, delivered end to end

Global interconnect, multi-branch WAN and direct cloud access are not about “buying bandwidth”. They need a circuit with clear demarcation points, a defined service level and one accountable party. Our principle: define the service level first, design the path second, pick the bandwidth last.

GSS holds MIIT value-added telecommunications licences (ICP / ISP / IDC) and takes responsibility for carrier selection, local loops, cross-border coordination, CPE and on-site work — closing the gap between resellers who sell contracts without field execution and carriers whose responsibility stops at the street:

Delivery stageCommon issueGSS approach
Carrier selectionLocked into a single carrier; no genuine physical dual-route redundancyCompare China Telecom, China Unicom, China Mobile and international partners; design diverse-path dual uplinks
Last mileCarrier demarcation ends outside the building; risers and cabling unattendedField engineers across 200+ cities handle building surveys, riser routing, fibre splicing, CPE installation and commissioning
Cross-borderPublic VPN with no service levelDedicated IEPL / MPLS circuits via GSS overseas PoPs, delivered and operated from Beijing and Shanghai
Service levelBandwidth ceiling only, no end-to-end metricsSegment latency budgets and protection-switch targets written into the order; active-active NOCs with minute-level monitoring

Cross-border connectivity through GSS PoPs

For multinational China branches and Chinese enterprises expanding abroad, GSS operates its own PoPs in Tokyo, Hong Kong, Singapore and Los Angeles. Cross-border IEPL / MPLS circuits are carried by partner carriers and delivered and operated by GSS, so you never deal with overseas carriers directly.

RouteCircuit typeTypical bandwidthTypical one-way latency (reference)
Shenzhen ↔ Hong KongCross-border IEPL10M – 10G< 5 ms
Shanghai ↔ TokyoCross-border IEPL10M – 1G≈ 40 ms
Beijing ↔ SingaporeCross-border MPLS2M – 1G≈ 75 ms
Shanghai ↔ Los AngelesCross-border IEPL10M – 1G≈ 140 ms

Latency figures are typical reference values and depend on local loop and routing; the order specifies the committed metrics per circuit.

SD-WAN hybrid networking

Enterprise SD-WAN layered over dedicated circuits keeps critical and real-time traffic on circuits while non-critical traffic uses local Internet, with policy-based switching between links. The effect on total network cost depends on your current baseline, which GSS assesses during design. GSS provides CPE selection, configuration rollout and ongoing operations.

Engagement models

  • Single circuit: purchased per site and bandwidth; GSS delivers and operates.
  • Multi-site network: one design, phased delivery, one service interface.
  • Connectivity plus operations: combined with managed infrastructure services so circuits, CPE and site equipment share one monitoring and ticketing system.

Service levels, lead times and responsibility boundaries are defined in the order.

Delivery process

Delivery process

Requirements and site survey

Confirm site address, bandwidth, target service level and budget; run local-loop feasibility checks where needed.

Route comparison

Route combinations, alternatives and segmented costs delivered typically within 1–3 business days.

Provisioning and testing

Local engineers handle the last mile and CPE installation; cross-border circuits are jointly tested with partner carriers.

24/7 operations

Monitored from active-active NOCs in Beijing and Shanghai with ticketing, monthly reporting and ongoing route optimisation.

FAQ

FAQ

How does a cross-border circuit differ from Internet VPN?

IEPL / MPLS circuits are dedicated carrier capacity whose latency, jitter and availability can be committed in the order. Internet VPN rides the public Internet with no service-level commitment. Compliance judgements on data transfer rest with your legal team; GSS provides auditable technical controls and documentation.

Who issues the contract?

GSS (Beijing GoldSunshine Ltd.) contracts in China. Overseas segments are delivered by partner carriers — you deal with a single accountable party.

How fast can a circuit be delivered?

Domestic DIA in fibre-ready buildings typically in about 10 business days; 4G / 5G access typically within 3 business days; cross-border IEPL typically 20–45 business days. These are typical lead times; the order confirms the committed date.

Do you support redundant circuits?

Yes. We design dual circuits from different carriers over diverse physical routes, with SD-WAN for policy-based switching between links.
