Packet Manager

Overview

Packet Manager performs the following functions:

1. Reads/writes registration packets from/to the Object Store.

2. Performs in-memory encryption and decryption of packets.

3. Performs security checks, checksum, file validations, ID object validations, etc. on the registration packet.

4. Provides packet information to other services via APIs. In case of multiple packets associated with an ID, pulls information from packets based on configured priority. (See packetmanager.default.priority).

Packet Manager runs as a service and is also available as a library.

The relationship of the Packet Manager with other services is explained here.
