摘要： In a general connection service using the PPPoE protocol, since user determination cannot be performed before a PPP authentication phase, even when a connection request is received from an invalid user, an access server and an authentication server operate under loaded conditions. Accordingly, an invalid user list is held in the access server, and user information is added to a PADI packet. In this arrangement, an invalid user can be determined at early stages and the packet can be deleted, thereby the load can be reduced. Further, regarding the invalid user, pseudo-connection completion is made and an occurrence of retry is prevented, thereby the load can be reduced.

摘要翻译： 在使用PPPoE协议的通用连接服务中，由于在PPP认证阶段之前不能执行用户确定，即使从无效用户接收到连接请求，访问服务器和认证服务器在加载条件下运行。 因此，在接入服务器中保存无效的用户列表，并将用户信息添加到PADI分组。 在这种布置中，可以在早期阶段确定无效用户，并且可以删除分组，从而可以减少负载。 此外，关于无效用户，进行伪连接完成，并且防止重试的发生，从而可以减少负载。

摘要： One physical VLAN server provides a plurality of VLANs with services. VLANs #1 to #3 are connected to the VLAN server though a switching hub. The VLAN server includes server processes #1 to #3 corresponding to the VLANs #1 to #3, respectively, for providing the VLANs with services. The server processes #1 to #3 each have internal IP addresses N1, N2, and N3. The VLAN server has external IP addresses G1, G2, and G3 for the VLANs #1 to #3, respectively. When a client #1-1 on the VLAN #1 issues data to the VLAN server with the destination IP address being set to G1, a receiving-VLAN-tag-NAT processing section of a device driver in the VLAN server changes the destination IP address from G1 to N1 with the use of a VLAN tag V1, and the server process #1 receives the data

摘要： A method for processing data received from at least one of VLANs, the method including: obtaining, based on a VLAN tag included in a MAC header of a MAC frame received from the VLAN and a first destination IP address included in an IP header of the MAC frame, a second destination IP address, changing the first destination IP address of the IP header to the second destination IP address, and generating an IP packet by deleting the MAC header from the MAC frame.
