Benefits of technology

The present invention is about creating an access system with Ethernet technology that allows a practically unrestricted number of users to access services through a network. The system should offer a wide range of services to users and securely bind service providers to users. The system should also allow for individual or multicast service access relations, control traffic, and utilize Ethernet technology for establishing service bindings. The invention has the advantage of creating a multiservice access network with standard Ethernet components and simplifying administration and configuration of the network.

Problems solved by technology

Another problem is how to offer the users sevices via the system, a number of the services practically covering all offered services.
A further problem is how to offer secure service bindings between the users and the service providers.
Still a problem is how to establish the service bindings as unicast bindings.

Embodiment Construction

[0047]FIG. 1 shows a multiservice access system ACC1 to which users U11, U12, U13, U21, . . . , Um1 and service providers SP1, SP2, . . . , SPn are connected. An objective is to build the system such that the number of the users U11 . . . Um1 can be very great, e.g. in the range of several hundred thousands users. Another objective is that the number of the service providers SP1 . . . SPn, that each user can utilize, also is a great number, e.g. in the range of thousands of services. The access system ACC1 includes nodes P1, P2 . . . Pk, to which the users are connected with the aid of Ethernet technology. The access system also includes a node EAS, to which the service providers are connected. The node EAS is connected to the user's nodes P1-Pk via a network, which is an Ethernet based network ETH1 according to the standard IEEE 802.1q. This network is a large network and has among others a number of VLAN capable Ethernet switches, not shown in the figure. The users and the service...

Abstract

An access system (ACC1) for relating service providers (SP1-SPn) to users (U11-Um1) includes an edge access server (EAS) connecting the service providers and penults (P1-Pk) connecting the users. User devices (UD11-UD14) are connected via VLAN:s to a user port (UP11) on the penult. The edge access server has service agents (SA1-SAn), an administrator (AD1) and a broadcast handler (BH1), which forms a handling system together with handlers (H1-Hk) in the penults. A user (U11) decision including VLAN, service (SP1) and user port (UP11) is sent to the administrator (AD1), which dynamically allocates to the relevant service agent (SA1) a MAC address, defining a relationship (R11). A user device (UD11) broadcasts a DHCP request unicasted together with user port (UP11) to the broadcast handler (BH1). The user device (UD11) gets its IP address and IP address to the service agent (SA1). The device (UD11) broadcasts an ARP request which is unicasted by the penult (P1), to get the MAC address to the service agent (SA1). The relations (R11, R21) are secure and can easily

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates to a multiservice Ethernet access system and methods of establishing service access relations in the system. DESCRIPTION OF RELATED ART [0002] Ethernet has been developed mainly as a LAN (Local Area Network) technology, aiming to provide an efficient infrastructure for data networks within a company. Originally it was developed for moderate speed shared media, but current technology applies mainly to point-to-point links up to 10 Gbit / s, interconnected by high capacity Ethernet switches, supporting virtual LAN. VLADN, as described in the standard IEEE 802.1q. A virtual LAN is a group of system, such as computers in a workgroup, that need to communicate with each other, and protocols that restrict the delivery of VLAN frames to members of the VLAN. [0003] A LAN can be partitioned into multiple VLAN:s, where each VLAN is assigned a number called a VLAN identifier that identifies it uniquely within the LAN. A LAN con...
