Network services are the foundation of a networked computing environment. Generally network services are installed on one or more servers to provide shared resources to client computers.Network services are configured on corporate LAN’s to ensure security and user friendly operation. They help the LAN run smoothly and efficiently. Corporate LANs use network services such as DNS (Domain Name System) to give names to IP and MAC addresses (people remember names like “nm.lan” better than they remember numbers like “210.121.67.18”), and DHCP to ensure that everyone on the network has a valid IP address.DHCP eases administrative burden by automating the IP assignment of nodes on the network. Adding or removing nodes from the network doesn’t create problems with IP address retrieval; the DHCP service handles this automatically. Authentication servers are another network service, they allow every user to have their own account, and everything they do on that account is logged under their user name. This means that not only are users accountable for anything they do while on the network, but also it increases security as anyone wanting to access the LAN must have a registered user name and password.
Doing network administration without having user accounts to track user activity or DHCP to automate IP assignment to nodes, or DNS to simplify IP address access would be troublesome indeed. Enabling these few network services automates complex and time consuming administration to the network, and thus eases downtime for network administrators.

In the last five years, the networking research community has worked on active technology. The main focus on this effort has been on developing technology that allows the rapid deployment of new functionality, such as data processing or control protocols, by dynamically inserting mobile code segments, which we will call delegates, into the network. In this proposal we will demonstrate that active networking can also help in addressing the scalability and complexity issues described above. In particular, we believe that coordinated groups of distributed locally-customized delegates can implement both advanced core-network and value-added services. The key observation is that not all network nodes need to implement identical functions. By properly assigning delegates with different functionality to nodes that have different scalability constraints or that face different traffic conditions or functional requirements, and by coordinating the actions of these delegates, it is possible to implement a wide range of advanced services with a level of scalability and efficiency that so far has been impossible to achieve with conventional techniques.
