MEMBANGUN JARINGAN INTRANET DENGAN MELEWATKAN VLAN DIATAS VPN MENGGUNAKAN METODE PPTP BCP

Internet sudah menjadi kebutuhan wajib bagi organisasi atau perkantoran, Terutama kantor yang memiliki cabang yang jaraknya jauh dengan kantor pusat. Untuk menghubungkan antar perusahaan yang  saling berjauhan agar tetap dapat bertukar informasi atau data bisa menyewa leased line namun memerlukan biaya yang cukup mahal. Dari permasalahan tersebut penulis memunculkan gagasan memanfaatkan tunneling diatas internet. Internet merupakan jaringan publik yang telah tersebar luas dan mendunia sehingga dapat digunakan dengan mudah. Sebuah teknologi komunikasi Virtual Private Network yang memungkinkan jaringan komputer dimana antar perangkatnya terhubung memanfaatkan jaringan publik(internet) sehingga diperlukan koneksi internet pada masing-masing kantor pusat dan cabang. Setiap kantor pusat dan cabang memiliki 3 departement yang berbeda. Setiap departement nantinya akan di pisah menjadi beberapa segment seperti departement admin dengan departement admin saja yang dapat terhubung. Untuk itu dapat menggunakan metode Bridge Control Protocol  yang memungkinkan untuk meneruskan paket melalui tunneling Point-to-Point Tunneling Protocol(PPTP) dan untuk memisahkan departement antar kantor pusat dan cabang dapat menggunakan jaringan Virtual Local Area Network(VLAN) yang nantinya setiap departement diberikan identitas(ID) sesuai dengan departement yang ada pada kantor pusat dan cabang. Hasil dari penelitian menunjukkan bahwa dengan adanya internet yang terhubung pada setiap kantor pusat dan cabang dapat dimanfaatkan sebagai media penghubung untuk membentuk koneksi tunnel VPN. Setelah VPN tunnel terbentuk, rute yang dilalui antara kantor pusat dengan kantor cabang seperti berada pada satu jaringan LAN yang sama dan juga dengan menggunakan metode VLAN dapat membuat segment jaringan lebih kecil seperti halnya sesama departement dapat saling terhubung dan jika berbeda departement ingin saling terhubung maka kedua departement yang berbeda tersebut harus menggunakan default gateway yang menuju ke router kantor masing-masing departement.

Sentralisasi Manajemen Hotspot Menggunakan Transparent Bridge Tunnel EoIP over SSTP

STMIK Bumigora is the first computer college in the province of West Nusa Tenggara (NTB). There are 11 hotspots spread across the campus to provide Internet services through a wireless connection for the academic community. The increasing number of hotspots that must be managed with locations scattered in various Mikrotik routers hence make the process of management and monitoring hotspots become complex, ineffective and efficient. Centralized campus hotspot management using a transparent bridge EoIP over SSTP can help solve the problems at hand. Ethernet over IP (EoIP) Tunneling is a Mikrotik RouterOS protocol that creates an Ethernet tunnel between routers over IP connections. EoIP tunnel built on SSTP tunnel (EoIP over SSTP) with Site-to-Site type. SSTP is a new form of Virtual Private Network (VPN) tunnel that provides a mechanism for encapsulating Point-toPoint Protocol (PPP) traffic through the SSL path of the HTTPS protocol. The IP address of the SSTP interface is used as the local reference and remote address of the EoIP over SSTP tunnel. The application of bridging on EoIP interfaces and interfaces connected to Access Point devices forms a logical network so that the management and monitoring of hotspot services can be performed centrally on one router

IMPLEMENTATION OF PPTP AND BCP WITH INTER- VLAN ON THE TOPOLOGY THAT USES 2 ISP AS INTER-DIVISION CONNECTORS (Case Study: PT Kenari Djaja Prima)

PT Kenari Djaja Prima will create a tunnel between branch offices located far from the central office so that these two offices can retrieve data on the server. As well as forming a local network between branch offices and centers. From the problem, the authors conducted a study and proposed using VLANs to divide divisions, and the tunnel method in the form of PPTP as encryption tunnel to connect with branch offices and BCP methods to forward ethernet packets so that the IP segmentation of headquarters with branches could be connected. From the results of this study, the average maximum Mbps obtained from downloads is 25.87 Mb, the average is at least 1.19 Mb, the average speed is 15.24 Mb, the average time is one minute and thirty seven seconds, and the average delay is 200.28 MS. The conclusion obtained in this study is that division of divisions with VLANs can be overcome, and between divisions have their own VLAN IDs, and can communicate with each other using Inter-VLAN. And use tunnels to connect branch offices with headquarters using PPTP. PPTP as tunnel encryption, EoIP as an ethernet connector and as a VLAN distribution between headquarters and branches. So that the data will be safe until the destination.Keywords: PPTP, QoS, VLAN, Inter-VLA

Analisis Kecepatan Transfer Data Point To Point Tunneling Protocol

Virtual Private Network (VPN) menggunakan Point to Point Tunneling Protocol (PPTP) dapat digunakan untuk integrasi jaringan. Jaringan yang terletak pada lokasi berbeda dapat dilakukan integrasi melewati jaringan publik Internet. Kemampuan penyatuan jaringan ini tidak terbatas pada lokasi yang berjauhan. Yang diperlukan adalah bahwa masing-masing jaringan terhubung melalui jaringan publik. Integrasi jaringan dilakukan menggunakan fitur kanal tersembunyi. Penerapan VPN melibatkan aspek penyembunyian data dan kompresi data. Aspek penyembunyian data berkaitan dengan enkripsi data ketika data ditransfer melalui kanal VPN. Aspek kompresi berkaitan dengan pengurangan ukuran data ketika ditransfer melewati kanal VPN. Proses enkripsi dan kompresi data akan memengaruhi kecepatan transfer data secara keseluruhan. Proses enkripsi menyebabkan transfer data tertunda beberapa saat. Proses kompresi pada satu sisi menyebabkan berkurangnya ukuran data yang ditransfer. Namun proses kompresi memerlukan waktu tersendiri yang berpengaruh pada proses transfer data secara keseluruhan. Hasil penelitian menunjukkan bahwa enkripsi dan kompresi menyebabkan penurunan kecepatan transfer data melalui kanal VPN PPTP. Salah satu metode kompresi menggunakan use-vj-compression tidak secara signifikan menyebabkan penurunan kecepatan transfer data

Poor Philanthropist: How and Why the Poor Help Each Other

This monograph documents the results of a qualitative research inquiry conducted by the Building Community Philanthropy Project into the philanthropic impulse and behaviour of the poor. It documents the comparative findings across four countries - Mozambique, Namibia, South Africa and Zimbabwe - into how and why people who are poor help each other. Describing the ethos of help among the poor, the monograph explores how philanthropy is organised - its purpose, rules of engagement, form and content, its actors and the motivations behind it

Rivaroxaban in atrial fibrillation cardioversion: an update

Currently, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with a prevalence of about 2-3% in the general population, representing a powerful risk factor for stroke and systemic thromboembolism and increased mortality and morbidity. Restoration of sinus rhythm is an important treatment option in AF and has a high success rate, but there is the need for an effective anticoagulation strategy to reduce the risk of embolic events. Anticoagulation with vitamin K antagonists is often associated with failure to achieving effective international normalized ratio. In this setting, recent data have led to extended approval for rivaroxaban in clinical practice, because it is effective and safe in patients with AF undergoing cardioversion, avoiding additional health costs and related time loss, while improving patient satisfaction. The present report provides an overview of the main randomized controlled trial and the main real-life studies, documenting the use of rivaroxaban in patients with non-valvular AF who underwent the cardioversion procedure. Considering that novel non-vitamin K antagonist oral anticoagulants in left atrial appendage thrombi resolution is still unknown in the real-world practice, the main findings on the use of rivaroxaban in this setting are also discussed
