A cluster connection is a method of connecting to a remote machine by setting up a TCP/IP connection between two computer servers to form a cluster. A cluster connection is only possible between servers running the same operating system. Cluster connections may not be available for all server software.
When a cluster connection is established between two computers, data is sent over two or more parallel TCP/IP connections, instead of a single data connection. The use of multiple connections reduces the load on a single connection. The load is reduced because the connection between two machines is established separately from other connections, but is still maintained.
One reason to establish a cluster connection is to minimize the impact of any potential downtime due to a failure in a connection. This is important for users who maintain critical mission-critical applications.
There are three types of cluster connections:
Round Robin Connections
Synchronous Connections
Point-to-point Connections
When choosing a connection type, users should consider the traffic expected between the two servers, and the type of data that must be exchanged. Point-to-point connections can be slow because the data must be relayed via a router, possibly over several hops. Round robin connections, on the other hand, are faster. Round robin connections minimize the amount of time any one server is waiting to hear from the other. Synchronous connections use a computer clock to set up and tear down a connection, rather than set up and tear down as a round robin connection does.
Examples of cluster connections
Both servers in a cluster must be of the same type
Both servers in a cluster should be running the same operating system
Each server in a cluster should be running the same operating system

This article uses the experience of the elderly in Israel to investigate the impact of social class on access to hospital-based medical services. Social class is conceptualized as a "social institution" whose distribution is conditioned by a set of social rules that govern access to the state and to other forms of welfare. These rules apply equally to the elderly, who constitute the group with the least access to hospital-based services. The result is that the elderly of the middle and upper classes have significantly better access to
