Patent number 8543674 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "FIG. 1 shows a generic description of a broadband network for providing telephone, internet and TV/video services to subscribers in a number of locations. A series of service providers provide the various services (SP1, SP2, SP3) to the network 10 via conventional access points 12. The network 10 provides connection to these subscribers via routers 14 located close to the subscribers. The subscribers can include business locations that can include routers in commercial property 16, and domestic subscribers with routers located in a central office 18 for a neighbourhood of separate dwellings (houses 17), or in a single building 19 such as an apartment. A network operator manages the network function by the use of a control and provisioning system 20. The present invention is particularly applicable to such networks.
"For the function of the control and provisioning system 20, the network can be considered in an abstract way as comprising a core 22 having one or more cells 24, each cell having one or more network elements 26 as is shown in FIG. 2. Subscribers 28 connect to the network elements 26. This structure is not to be confused with the physical elements making up the network. The functional blocks 22, 24, 26 may be wholly or partly resident in the same or different physical elements, depending on the exact size and makeup of the network in question, although typically, each network element 26 will comprise a router. The subscribers (network clients) can comprises a PC or other connected network device.
"Internet Protocol (IP) is the common form of communication used in most networks. Data communication using IP relies on addressing for the various parts of the network to be able to communicate with each other. An IP address (Internet Protocol address) is a unique address that certain electronic devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP). Any participating network device--including routers, computers, time-servers, printers, Internet fax machines, and some telephones--can have their own unique address.
"IP addresses can be static or dynamic. A static IP address is one in which a device uses the same address every time a user logs on to a network. With a static IP address, a computer's identity can be easily identified by others, and users can easily connect with it. Such an approach is commonly used for websites, email servers and the like.
"A dynamic IP address is one in which the address is assigned to a device, usually by a remote server which is acting as a Dynamic Host Configuration Protocol (DHCP) server. IP addresses assigned using DHCP may change depending on the addresses available in the defined pool assigned to that server. Dynamic IP addresses are used because they provide efficient use of a limited pool of available addresses. When there is no need to assign a specific IP Address to each device, users can simply log in and out and use the network without having to have previously obtained an assigned IP address.
