Publication number: 20050190775Abstract: An access system (ACC1) for relating communication service providers (SP1-SPn) and application service providers (AS) 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 user port (UP11) on the penult. Service agents (SA1-San, ASA), an administrator (AD1), a broadcast handler (BH1) and handlers (H1-Hk) in the penults form a handling system. 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 relation (r11). A user device (UD11) broadcasts an ARP request to get the MAC address to teh service agent (SA1). A service access relation to the application service provider (AS) is provided such that it can be reached by users having relations (R11, R21) to the communication service providers (SP1-SPn).Type: ApplicationFiled: February 7, 2003Publication date: September 1, 2005Inventors: Ingmar Tonnby, Ulf Larsson

User devices (UD11-UD14) are connected via VLAN:s to a user ports (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 relation (R11). A user device (UD11) broadcasts a DHCP request unicasted together with user port (UP11) to the braoadcast 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).Type: ApplicationFiled: January 7, 2003Publication date: July 28, 2005Inventors: Ingmar Tonnby, Ulf Larsson, Tom Rindborg, Joacim Halen, Eric Hjelmestam, Egbert-Jan Sol
