It gives you sockets that carry whole messages across various transports like in-process, inter- process, TCP, and multicast. You can connect sockets N-to-N with patterns like fanout, pub-sub, task distribution, and request-reply. It's fast enough to be the fabric for clustered products. Its asynchronous I/O model gives you scalable multicore applications, built as asynchronous message-processing tasks. It has a score of language APIs and runs on most operating systems. ØMQ is from iMatix and is LGPL open source. http://www.zeromq.org/ if BR2_PACKAGE_ZEROMQ comment "norm support needs a toolchain w/ dynamic library" depends on BR2_STATIC_LIBS config BR2_PACKAGE_ZEROMQ_NORM bool "NORM support" depends on !BR2_STATIC_LIBS select BR2_PACKAGE_NORM help Add support for NACK-Oriented Reliable Multicast (RFC 5740) protocol. comment "PGM/EPGM support needs a toolchain w/ wchar" depends on BR2_TOOLCHAIN_HAS_SYNC_2 depends on BR2_TOOLCHAIN_HAS_SYNC_4 depends on !BR2_USE_WCHAR config BR2_PACKAGE_ZEROMQ_PGM bool "PGM/EPGM support" depends on BR2_TOOLCHAIN_HAS_SYNC_2 depends on BR2_TOOLCHAIN_HAS_SYNC_4 depends on BR2_USE_WCHAR # openpgm select BR2_PACKAGE_OPENPGM help Add support for Pragmatic General Multicast protocol (RFC 3208) implemented either over raw IP packets or UDP datagrams (encapsulated PGM). endif
