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-to-Point 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.

Research on the Net Transparent Bridge Technology Based Single NC Machine’s Network Integration

In the face of the development trends of NC machine’s networking, this paper presents a new method of transferring NC program based on net transparent bridge technology. By analyzing the principle of serial port communication between NC machine tool and computer, this paper demonstrates the fundamental of net transparent bridge, topology structure, software and hardware realizing of communication function. The single NC machine networking in field showed that the preset qualifications can be reached, which makes the network integrations of existing single NC machines possible.

SUBOPTIMAL-OPTIMAL ROUTING FOR LAN INTERNETWORKING USING TRANSPARENT BRIDGES

The current standard transparent bridge protocol IEEE-802.1D is based on the Spanning Tree (ST) algorithm. It has a very important restriction: it cannot work when the topology has active loops. Therefore, a tree is the only possible interconnection topology that can be used. The ST algorithm guarantees that the active topology is a tree discarding lines that form loops. However, because of this, network bandwidth cannot be fully utilized. Moreover, trees have a very serious bottleneck near the root. This paper proposes a new transparent bridge protocol for LAN interconnection that allows active loops. Therefore, strongly connected regular topologies like tori, hypercubes, meshes, etc., as well as irregular topologies can be used without wasting bandwidth. As loops provide alternative paths, the new protocol (named OSR for Optimal-Suboptimal Routing) uses optimal routing or, in the worst case, suboptimal routing.
