Abstract

The use 802.11 wireless-based network services have become one of the most widely used network services, this will be directly proportional to the security holes that are in the wireless network. The rise of access rights theft in wireless networks is due to the large number of software and tools available on the internet to read encryption in wireless security. To minimize the occurrence of theft of access rights in wireless networks can use a layered security system by implementing security Hotspot login and MAC Address Filtering. This layered wireless network security is able to block users who try to access the network. This is because the wireless network security system has verified access rights 2 (two) times by matching the username and password in the hotspot login with the physical address or MAC address of the client. From the research results obtained by clients who use a username and password with different devices can not access the computer network. So every client who wants to connect to the internet network must use a device that has registered its MAC Address and in accordance with user access rights and passwords in the Hotspot login

Abstract

Quality of Service (QoS) di dalam sebuah layanan jaringan menjadi faktor terpenting untuk memastikan kapasitas transfer paket data. Salah satunya pemilihan protokol routing yang akan digunakan. Routing Protokol Open Short Path First (OSPF) menggunakan metode Cost Manipulation mampu menjadi sebuah alternatif solusi untuk mamastikan QoS di dalam layanan jaringan dikarenakan metode Cost Manipulation mampu memilih jalan terbaik menuju network tujuan tanpa mempertimbangkan kembali metrik yang seharusnya, baik shortest path ke network tujuan ataupun bandwidth-nya. Hasil pengujian tracerroute sebelum pengimplementasian OSPF cost manipulation didapatkan hanya menggunakan 1 (satu) single line saja dan packet loss yang didapatkan saat terjadinya link failure dengan pengiriman 907 packet data adalah 1,4 packet loss. Sedangkan setelah pengimplementasi OSPF cost manipulation dapat menggunakan 2 (dua) dual line sebagai load balancing dan packet loss yang didapatkan menurun dengan hasil rata-rata sebesar 0,6 packet loss dan pengimplementasian cost manipulation mampu membagi transfer paket data dengan sama rata.
