In Web server cluster system design, high reliability and efficient services are major goals. High reliability has been achieved through DNS dispatching technique and data replication scheme. A model called Neighbour Replication Distribution Technique (NRDT) has been proven mathematically to provide availability of data. Before this, DNS dispatching and data replication scheme based on NRDT has been...
This work presents SAPOTI (Dependable TCP/IP application servers - in portuguese: servidores de aPlicacoes cOnfiaveis Tcp/Ip), a distributed tool that guarantees the availability of TCP/IP application servers, in particular of Web servers. The tool is based on the SNMP framework and is executed on a group of Web servers running on a set of hosts that are monitored by a dependable distributed network...
