Embodiment Construction

[0026] Figure 1 shows a view of the access system ACC1. The system has an access node EDA1 to which end users EU1 and EU2 are connected. Three service provider access routers R1, R2 and R3 providing services to end users are connected to the access node. The first router R1 is an IP router in the Internet virtual local area network indicated by IV1. The second router R2 is a voice gateway in the voice virtual local area network represented by VV1. The third router R3 is a video server in the video virtual local area network represented by VV2. The three routers R1, R2 and R3 have IP media access control addresses MACX, MACY and MACZ respectively. A Dynamic Host Configuration Protocol server DH1 in the Dynamic Host Configuration Protocol virtual local area network denoted DV1 is also connected to the access node EDA1.

[0027] Media access control filters (filters) MX, MY, and MZ that only allow the respective IP media access control addresses MACX, MACY, and MACZ to pass a...

Abstract

An access node (EDAl) is connected to end-users (EUl, EU2) , routers (R1,R2,R3) and a DHCP-server (DHl) . The end-user (EUl) defines desired services provided via the routers. A purpose is to automatically provide simultaneous access to services via two or more of the routers, although the end- user (EUl) simultaneously handles only one router. The connections are secure. The end-user requests (RQl) one of the services. The access node identifies the end-user (EUl) and sends a corresponding request (RQ2) to the DHCP- server (DHl) , which dynamically allocates addresses to the end-user and to all the routers for the desired services. The access node snoops the addresses in a DHCP otption 121 message (RPl) from the DHCP-server (DHl) , resolves the router addresses, stores IP router addresses and IP MAC addresses in a memory (TABl) and sets MAC addresses in MAC filters (MX, MY, MZ) .; An option 3 reply (RP2) with one router (Rl) is sent to the end-user (EUl) , which after request for one service reaches all the services stored in the memory (TABl) .

Description

technical field [0001] The present invention relates to providing various services in an access system. Background technique [0002] Users of services provided over telecommunication networks often require simultaneous access to multiple service providers. It is also important that the connection established is secure and cannot be used by other users than the one in question. [0003] A mechanism called MAC-Forced Forwarding (MFF) ensures a secure connection. This mechanism ensures that only all end users connected to a specific service virtual local area network (VLAN) in the Ethernet aggregation network are allowed to access the default gateway, and do not allow direct access to each other or other users attached to the service virtual local area network. edge nodes. The media access control push transfer mechanism also allows the access node connected by the end user to dynamically obtain the address of the default gateway, so as to allow the access of each end user'...
