JSON-RPC Protocol

A JSON-RPC Protocol is a remote procedure call protocol that enables distributed systems to exchange procedure calls using json format.

• Context:
  • It can establish Remote Communication through json messages.
  • It can enable Method Invocation through request objects.
  • It can support Result Handling through response objects.
  • It can maintain Version Compatibility through protocol versions.
  • It can handle Error States through error objects.
  • ...
  • It can often implement Batch Processing through request arrays.
  • It can often provide Notification Handling through notification objects.
  • It can often facilitate Service Discovery through method listings.
  • It can often support Session Management through connection tracking.
  • ...
  • It can range from being a Simple JSON Message Protocol to being a Complex RPC Framework, depending on its implementation scope.
  • It can range from being a Basic Data Exchange Protocol to being an Advanced Service Protocol, depending on its feature set.
  • ...
  • It can integrate with Transport Layer for message delivery.
  • It can connect to Application Layer for service integration.
  • It can support Security Layer for message protection.
  • ...
• Example(s):
  • Protocol Versions, such as:
    • JSON-RPC 1.0 for basic rpc.
    • JSON-RPC 2.0 for advanced features.
  • Transport Implementations, such as:
    • HTTP JSON-RPC for web services.
    • WebSocket JSON-RPC for real-time services.
    • TCP JSON-RPC for network services.
  • Message Types, such as:
    • Request Message for procedure invocation.
    • Response Message for result delivery.
    • Notification Message for one-way communication.
  • ...
• Counter-Example(s):
  • JSON REST Protocol, which uses resource-based architecture instead of procedure-based architecture.
  • JSON Message Protocol, which lacks remote procedure call capabilities.
  • JSON Schema Protocol, which validates data structures instead of executing procedures.
