MikroTik Experience Overview - Wireless ISP Solutions Arnis Riekstins, Chief Technical Officer John Tully, Managing Director, MikroTik Wireless Presentation Program Overview of MikroTik experience Basics of Wireless ISP solutions “Question and answer” to clarify the most important topics for the attendees Wireless ISM issues – interference Network infrastructure Traffic shaping AP setup and backbone routing Low cost wireless client setups with PPPoE 10.05.2002. MikroTik Overview 2 Contents MikroTik Company Overview What’s new in MikroTik RouterOS V2.5 PPPoE Overview and Applications PPTP Applications OSPF Routing and Backup Links Combining PPTP and OSPF for Backup Links 10.05.2002. MikroTik Overview 3 MikroTik Mission We create Intel (PC) based network solutions, because: Hardware cost can be adjusted to the client’s needs – contemporary or ‘server-quality’ Intel is the most powerful and most price attractive platform Easy hardware upgrade RouterOS can be easily upgraded with new functionality 10.05.2002. MikroTik Overview 4 MikroTik Mission (cont.) How do we do things?: We are a small WISP ourselves, therefore we are able to develop solutions for our customers based on our own experience Our customers are: Internet Service Providers (ISPs) Hardware wireless ISPs – more than 45 countries Software RouterOS – almost all countries (120+) Organizations requiring IP network solutions for their own needs – corporate networks (Intranets) 10.05.2002. MikroTik Overview 5 MikroTik’s History Active in WISP solutions since 1995 Incorporated in 1996 Wireless ISP Projects around the World Since 1996 Development of own Software for Intel (PC) based routing solutions 2002: 20+ employees (programmers, engineers, sales, technical support, administrative) 10.05.2002. MikroTik Overview 6 MikroTik News New Hardware platforms Software V2.5 released MikroTik provides training on wireless installations and network setup – next seminar in Prague, Czech Republic, June 26-28 10.05.2002. MikroTik Overview 7 New Hardware platforms MikroTik Thin Router 333MHz Processor, 10/100Mbps Ethernet, one expansion slot for ISA or PCI 19” Rackmount 4U – Silver Server style Gigabit Ethernet Prism II 200mW Wireless Interfaces 10.05.2002. MikroTik Overview 8 MikroTik RouterOS V2.5 PPPoE Access Concentrator 2.4GHz Access Point VPN (PPTP tunnels between routers) PPTP Access Concentrator (PPTP tunnels between the router and workstations) EoIP tunnels – for transparent bridging of networks 10.05.2002. MikroTik Overview 9 PPPoE Access Concentrator Usage: For Ethernet LANs, to assign IP addresses to workstations, e.g.: Multi-apartment buildings Offices, to provide user authentication and accounting Schools and universities, computer classes Connections to Wireless ISPs Connections to xDSL providers 10.05.2002. MikroTik Overview 10 PPPoE Access Concentrator Advantages User authentication 128bit tunnel between the workstation and the PPPoE Access Concentrator Easy user management using RADIUS server 10.05.2002. MikroTik Overview 11 VPN 128bit encrypted tunnels Applications: Permanent tunnels between routers PPTP Access Concentrator for many clients (Windows workstations) and mobile clients (work from home and while traveling) 10.05.2002. MikroTik Overview 12 Ethernet over IP (EoIP) Tunnels Application: To bridge Ethernet LANs Can be used together with PPTP tunnels Bandwidth can be limited over the tunnels Providers can sell bandwidth to the corporate customers for their Intranet needs 10.05.2002. MikroTik Overview 13 2.4GHz Access Point Can be used as IEEE 802.11b AP in several ways: Simple Access Point Wireless AP and Ethernet router in one box Wireless AP and PPPoE Access Concentrator Can have several wireless interfaces Can be a wireless client and an AP Can be used to register other APs and bridge the networks 10.05.2002. MikroTik Overview 14 Synchronous Adapters Cyclades PC300 V.35 Synchronous For leased lines with baseband modems, supports Frame Relay Cyclades PC300 E1/T1 For leased lines MOXA C101 V.35 Synchronous 10.05.2002.
