Method and system for creating, modifying and deleting a virtual CPE distributed

摘要

A method for creating, modifying and deleting a home gateway virtual client distributed, wherein at least one home gateway virtual client distributed (100) comprises: - an association between an identifier of access line and a client identifier wherein said association is stored in at least one Line Configuration Server (103); and - status information and configuration relative to said association, wherein said status information and settings are stored: partially, in at least one edge node IP (101) acting on a provider edge, providing forwarding tunneling traffic end client devices intended for Internet public IPv4 to at least one node NAT operator level (102), partly in at least one node NAT operator level (102) which provides translation NAT to IPv4 addresses public source for client traffic and partly in at least one configuration Server User (104) that provides: - configuration parameters IP selected by the customer from at least one node Edge IP (101), which enable act as a gateway IP address for end client devices connected to said access line through a bridge device, - parameters confi configuration of NAT for at least one node NAT level operator (102), which allow you to perform such translation NAT according to customer preferences, and - settings of IP dynamically to end-client devices, characterized that the method comprises the following steps: - creating said state information of at least one domestic virtual distributed gateway (100), by at least one edge node IP (101), upon receipt of traffic from an address in the access line corresponding to said line identifier access and after obtaining the at least one edge node IP (101) the client identifier associated with said line identifier accessed from the at least one Configuration Server Line (103) and having provided on at least one edge node IP (101) retransmission control traffic from client devices end labeled with said i dentificador access line and said client identifier to said at least one Configuration Server User (104), provided that at least one Configuration Server User (104) the IP, NAT and configuration parameters of IP based on the access line identifier and the client identifier added to control traffic from the client terminal devices by at least one IP node edge (101); - establishing a tunnel from said at least one edge node IP (101) to said at least one node NAT level operator (102) using said identifier access line and said client identifier as part of a header encapsulation to forward traffic end client devices intended for Internet public IPv4 from said at least one edge node IP (101) to said at least one node NAT level operator (102), said at least one node NAT level operator (102) the translation of NAT to public IPv4 addresses to client traffic source based on said encapsulation header; - modifying said configuration information of at least one home gateway distributed virtual client (100), by said at least one User Configuration Server (103) following a client request; and - removing said state information of at least one home gateway distributed virtual client (100) by said at least one Border Node IP (101) after a time delay for traffic inactivity detected in said access line or said at least one server line configuration (103) after an administrative instruction, wherein said association stored in the at least one server line configuration (103) is called context of home gateway virtual client (106), and known partially or completely by the at least one edge node IP (101), the at least one NAT level operator (102), the at least one Configuration Server User (104) and the at least one server Line configuration (103) and remains active throughout the life cycle of such home gateway virtual client distributed from creation to disposal.
