P2P SDK Network
Building a cross-platform bandwidth-sharing network with embedded SDKs
A distributed network business needed one SDK contract across Android, iOS, and desktop applications, plus a control plane for device identity, traffic eligibility, routing, analytics, and participant rewards.

The challenge
The product relied on applications that contributed available bandwidth from different operating systems and network environments. Early integrations were built independently, so authentication, connectivity recovery, telemetry, and background behavior diverged by platform.
A distributed device fleet cannot be operated as a collection of unrelated clients. The network needed a consistent device identity, remote policy, traffic eligibility rules, regional capacity view, and accounting model that could survive intermittent connectivity.
The commercial platform also needed trustworthy usage data. Participant rewards, referral attribution, support, and network optimization all depended on the same device and traffic records rather than platform-specific estimates.
Previous setup
SDK operation before consolidation
Platform-specific authentication and connection lifecycle code
Different retry and failover behavior across applications
Limited ability to change device policy after release
Fragmented usage and availability telemetry
Reward calculations built from delayed aggregates
Network capacity difficult to compare across regions and platforms
Architecture after ProxyRequest
Device SDKs
Shared identity and authentication
Background connection lifecycle
Local safety and eligibility checks
Buffered telemetry delivery
Network control
Remote configuration
Regional capacity and routing
Health-aware session assignment
Traffic policy enforcement
Platform services
Usage accounting
Reward and referral events
Fleet analytics
Operational support tools
Each SDK implements a shared lifecycle contract while retaining platform-specific system integration. The control plane decides eligibility and routing, records attributable usage, and publishes the events used by analytics and reward workflows.
Before / After
| Before | After |
|---|---|
| Independent connection logic per platform | Shared SDK lifecycle contract |
| Policy fixed until the next application release | Versioned remote configuration |
| Retry behavior varied between devices | Consistent recovery and failover semantics |
| Telemetry fragmented by client type | Normalized fleet and traffic events |
| Rewards inferred from delayed totals | Attributable usage-based accounting |
| Regional capacity assessed manually | Operational view across platform and geography |
Outcomes
New applications integrated through a consistent contract. Platform teams reused identity, connection, telemetry, and error-handling behavior instead of rebuilding network logic.
The fleet became remotely operable. Eligibility, routing, and safety policy could change without waiting for every application release.
Usage supported both operations and rewards. The same attributable records informed network optimization, support investigation, and participant accounting.
Intermittent devices became manageable capacity. Health-aware assignment and buffered telemetry kept regional availability visible despite changing connectivity.
