IP multicast was a natural choice for a communication\nchannel. Moreover, I wanted to explore the domain of implementing IPv6 multicast in Java 11+, \nespecially using NIO.\n\n## Alternatives\n### mdnsjava\nhttps://posicks.github.io/mdnsjava/\n\nDescribed as multicast DNS (mDNS) [RFC 6762] \u0026 DNS-Based Service Discovery (DNS-SD) [RFC 6763] in Java.\nI've started reading about this solution before inventing my own. However, I found it: \n- complicated and hard to integrate on a service side;\n- having bugs, including IPv6 support;\n- dead, as the last commit was made 6 years ago (it's 2023 now). See: https://github.com/posicks/mdnsjava \n\n### Hola\nhttps://github.com/fflewddur/hola\n\nDescribed as a minimalist Java implementation of Multicast DNS Service Discovery (mDNS-SD). \nThe purpose of Hola is to give Java developers a dead-simple API for finding Zeroconf-enabled \nservices on a local network. It follows RFCs 6762 and 6763 and is compatible with Apple's Bonjour \nmDNS-SD implementation.\n\nAll this sounds promising, but Hola is a work-in-progress and the last commit was 5 years ago (in 2023).\n\n### CU-Zeroconf\nhttps://github.com/faceless2/cu-zeroconf\n\nLooks like a response to some problems of mdnsjava. On the other hand the author claims his implementation\nis not correct as well and the last commit was 6 years ago (as of 2023).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fk-tomaszewski%2Fdiscovery","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fk-tomaszewski%2Fdiscovery","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fk-tomaszewski%2Fdiscovery/lists"}
