Carzaniga, Antonio Hall, Cyrus Toffetti Carughi, Giovanni Wolf, Alexander L. 2009 We address the problem that existing publish/subscribe messaging systems, including such commonly used ones as Apache’s ActiveMQ and IBM’s WebSphere MQ, exhibit degraded end-to-end throughput performance in a wide-area network setting. We contend that the cause of this problem is the lack of an appropriate routing protocol. Building on the idea of a content-based network, we introduce a protocol called B-DRP that can demonstrably improve the situation. A content-based network is a content-based publish/subscribe system architected as a datagram network: a message is forwarded hop-by-hop and delivered to any and all hosts that have expressed interest in the message content. This fits well with the character of a wide-area messaging system. B-DRP is based on two main techniques: a message delivery mechanism that utilizes and exploits unicast forwarding state, which can be easily maintained using standard protocols, and a probabilistic data structure to effciently represent and evaluate receiver interests. We present the design of B-DRP and the results of an experimental evaluation that demonstrates its support for improved throughput in a wide-area setting. application/pdf https://n2t.net/ark:/12658/srd1318340 https://susi.usi.ch/global/documents/318340 https://susi.usi.ch/documents/318340/files/ITR0906.pdf eng info:eu-repo/semantics/altIdentifier/ark/12658/srd1318340 info:eu-repo/semantics/openAccess License undefined info:eu-repo/classification/udc/004 Practical high-throughput content-based routing using unicast state and probabilistic encodings http://purl.org/coar/resource_type/c_816b
