What Is an End System?

End system (ES), a concept in an OSI network, refers to a host or node in an OSI network. Another key concept in an OSI network is the mid-range system (IS), which refers to routers and switches that transmit information over the network.

Shanxi Construction Bank considers adopting innovative Windows 2003 across the province

The above solution uses Microsoft's domain management, Windows 2003 load balancing and clustering technologies. The application of these technologies has the following advantages:

First, the Windows domain environment has the following security and administrative advantages:

1. Unified authentication through domain user accounts;

2. Standardize management of terminal servers and users through Group Policy;

3. Server and user security management through security group policies;

4. Unified user authentication ensures the uniqueness of user terminal sessions.

The application of load balancing technology also improves the availability of the system.

The terminal server group uses network load balancing. Windows 2003 Network Load Balancing uses a distribution algorithm to distribute the load evenly across multiple servers. At the same time, load balancing technology can also detect server failures and automatically redistribute load traffic to other servers. Terminal server groups therefore increase the scalability and availability of Terminal Services. In addition, the cluster technology effectively improves the security of the system.

The file server cluster uses dual-system hot backup. If a server in the cluster becomes unavailable due to failure or maintenance needs, resources and applications on that server are moved to other cluster nodes that are available. Then, if one file service fails, the end user can still read the configuration file from another file server in the cluster, and the user's data file will not be lost.

In addition, this solution is based on the Microsoft Operation Frame Work, which ensures the stability and safe operation of the system in terms of processes and management.
