Sažetak
Modern 'Layer-3' LAN switches, that are often installed as edge devices in ATM/LANE based network backbones, posses significant IP packet forwarding capabilities, and thereby have the potential to offload the traditional one-armed inter-ELAN routers. However, in environments with more than just a few of such LAN switches installed, an efficient utilization of available aggregate IP processing power, distributed on edge devices, can become difficult and inconvenient to achieve. The sub-optimal distribution of CPU intensive IP packet forwarding tasks also results in poor utilization of available aggregate bandwidth, unnecessary packet traversing through the ATM backbone, and introduction of single points of failure on the IP layer. In this paper we present a new method for managing distributed IP packet forwarding in ATM/LANE networks, based on introduction of virtual IP default gateway model and custom BUS filters for each ELAN/IP subnet. We discuss how the proposed method accomplishes an even distribution of IP forwarding tasks on all edge LAN switches, and describe our referent implementation on IBM ATM / LAN networking equipment.
