This project implements a flat naming system using consistent hashing (CH). It involves a distributed set of servers that manage key-value pairs with support for operations such as insertions, deletions, and lookups. The system includes CH name servers and a specialized bootstrap CH server that offers additional functionalities.
Facilitates nodes joining and leaving without major disruptions. Provides efficient mechanisms for insertion, lookup, and deletion operations. Not as efficient as a typical Distributed Hash Table.
Offers a reliable and uniform way to name resources, allowing their discovery and interaction through metadata retrieval.
Note: Basic implementation details are available within this project's repository.
The repository is organized into two folders:
Bootstrap Name Server: Contains files for the bootstrap server.Name Server: Contains files for regular name servers.
- Language: Java (v11.0.10)
- Required Environment: Java (open-jdk)
Navigate to the bootstrapServer directory and execute:
$ javac BootstrapServer.java
$ java BootstrapServer config_example.txtThe server will start and await connections.
In a separate terminal, navigate to the nameServer directory and execute:
$ javac NameServer.java
$ java NameServer config_example.txtConfiguration files are included in the repository.
- Lookup: Retrieves the associated value for a given key.
- Insert: Adds a new key-value pair to the system.
- Delete: Removes a key-value pair from the system.
- Keys are integers in the range [0, 1023].
- Values are alphanumeric strings without special characters.
- The CH name server IDs are also in the range [0, 1023].
- The Bootstrap name server, with ID 0, is a permanent, central node.
- Operations (lookup, insert, delete) start from the bootstrap name server.
- Servers communicate using socket connections.
- Consistent hashing is used, with each server knowing only its immediate neighbors.
- Bootstrap name server is known to all other servers.
- Server interactions (entry/exit) begin at the bootstrap server and proceed clockwise.
