Abstract : Design for performance is one of the most important considerations that a computer networks designer is interested in when building such a network. The 3-tiers hierarchical network architecture (tiers are access, distribution, and core) provides a high degree of availability, scalability, flexibility, security and manageability. While the connection between distribution and core as a layer 3 connection (routing using routing protocols like OSPF or EIGRP) has obvious advantages and importance, the access layer can be connected to the distribution via a layer 2 (switching) or layer 3 connection. Both designs have advantages and disadvantages. For example, in the case of switched access (switching between access and distribution), the management and troubleshooting will be more complicated. In the case of routed access (routing between access and distribution), the network administrator will lose the advantages of VLANs. Link aggregation technology, designed to increase network performance, supports both designs in diverse ways. In this work, the performance of the switched access and routed access designs were compared based on two elements: delay and packet loss. The two designs were emulated using GNS3 software then generate a synthetic data traffic between the network hosts. The results of the experiments showed that routed access-OSPF design is the highest in the delay criterion - a difference that does not significantly affect network performance in real environments - while at the same time it is the best in terms of data loss assessment. Due to the widespread use of the OSPF protocol, which is an open standard protocol, and due to the advantages of the routed access design such as reducing the complexity of the design, troubleshooting, and the high and stable performance, the study recommended adopting the routed access-OSPF design whenever possible.
