Any provisioning infrastructure should allow for this variability. Interestingly, the key technical challenges to provision services are similar, regardless of the business model chosen. Unless the right tools are put in place to assure rapid, error-free management, increased profits will likely elude providers. From the network service provider perspective, there is a need to associate and route network traffic from individual subscribers to their particular Internet service provider. In traditional cable offerings where the network operator is also the service provider, there is no need for this function.
Any subscriber attached to the network is also a customer of that network's services.
This refers to the use of pools of IP addresses for customers of specific ISPs so that routing can be used to direct traffic to and from the proper location. The primary changes required to support open access provisioning using source-based routing are in the area of IP address management. Address pools must be established and managed over potentially widely distributed networks. Most DHCP servers are not well designed for this task. There is a new communication requirement between the ISP and the network provider to set up and manage services.
