First Claim
1. A network system for management of hierarchical service and content distribution via directory enabled network, comprising:
- at least one level 4 service manager responsible for management of multiple content delivery network;
at least one level 3 service manager responsible for management of one of the content delivery networks having multiple data centers;
at least one level 2 service manager responsible for management of one of the data centers having multiple server farms or service engine farms; and
at least one level 1 service manager for establishing a directory information routing protocol with the at least one level 2 service manager.

Abstract
A network system is provided for management of hierarchical service and content distribution via a directory enabled network to improve performance of the content delivery network with a hierarchical service network infrastructure design. In accordance with the network system, a method and protocols are provided as to how to design the network of multiple data centers running existing Internet protocol and user'"'"'s proprietary protocols, allowing a user to obtain various Internet services, especially the content delivery service, in a scalable and fault tolerant way. The network system is constructed into 4 layers, each layer is represented and managed by a service manager with back up mirrored managers. The layer 4 service manager is responsible for management of multiple CDN (content delivery network). The layer 3 service manager is responsible for management of one CDN network that has multiple data centers. The layer 2 service manager is responsible for management of one data center that has multiple server farms or service engine farms. The layer 1 service manager is responsible for all servers in a server farm. Each server of the server farm can be connected by LAN Ethernet Switch Network that supports the layer 2 multicast operations or by Infiniband switch which is the new industry I/O specification for server design.
