Services
The Handler provides the following services:
- Manages network connections.
- Implements Session Security/Authentication.
- Supports FIX Simple Binary Encoding (SBE), delivering faster encoding/decoding.
- Supports FIXP Performance (FIXP) session management point-to-point session layer protocol.
- Manages the FIXP application layer (defines business-related data content).
- Creates (outgoing) SBE messages.
- Parses (incoming) SBE messages.
- Persists messages and session state.
- Recovers the FIXP session state after restarting.
- Detects the telecommunication link failures and reconnects automatically.
- Supports Solarflare Onload Application Accelerator Extensions APIs to ensure the lowest possible latency and minimal jitter.
