ATM ON THE WORLD TECHNOLOGY NETWORK

This tutorial provides the basic introduction to atm network technology, packet switching, cell base, telecommmunication technology, high speed bandwidth usage in this technology. ATM (Asynchronous Transfer Mode) is a high speed network technology that has become the standardized solution for the telecommunication industry, teleconferencing, videoconferencing, telemedicine, HDTV, distance learning and where high speed data transfer is required.

ATM technology integrates voice, data and video at the same time. ATM uses fixed size packets called cells of 55 bytes in length. ATM network is a high speed circuit switched network that is capable of transferring one million signals using ATM protocol. ATM is a connection oriented technology in which logical connections are established for the data communication. ATM is implemented in the WAN and telecommunication sectors. Small data cells are used for communication and ATM is designed for high speed and high traffic networks. ATM cells allow voice, data and video transfer at the same time. ATM operates on the data link layer of the OSI model and it uses UTP/STP, fiber optic or air as a communication medium.

ATM CELL BASE

It is a small unit of 55 bytes fixed length and it contains the users and signaling information in it. It has a header with very limited functionality to reduce the internal buffer and to provide the high speed transfer. ATM cell identify the cells that belongs to the same virtual channels and perform easy routing.

ATM SWITCHING

Various switching technologies have been developed in the past to provide the high speed data transfer and secure communication. ATM switching technology provides high speed data transfer due to the connection oriented technology. ATM switching technology uses the predefined routing table so guarantees the fast data communication.

ATM DEVICES

ATM basically uses two types of devices such as ATM switch and end systems. The function of the switch is to handle the transmission of the cells throughout the network. Switches accept the incoming cells from the ATM end station or another ATM switch. On the other hand, ATM end systems contain the ATM adaptors.

ATM CONNECTIONS

ATM supports two types of connections point to point and point to multi point connections. In the point to point connections, two end systems are connected bi directionally or uni directionally. The point to multi point system connects one source to the number of destinations in uni directional. The source sends the information and switch replicates it to the destinations. Unidirectional network connects two switches. A typical ATM network consists of a set of the switches interconnected by point to point links. Switch support two types of interfaces user network and network node interface. Asynchronous transfer mode technology is designed for the reliability, performance, utilization and QOS and it creates fixed channels and routes when data travels between two points. There are four types of the choice when purchasing a connection.

Constant Bit Rate: It specifies fixed size rate and data is transferred in a steady form. Variable bit rate.Variable Bit Rate: It provides specified throughput and it is best for videoconferencing. Available bit rate. It provides guaranteed minimum capacity but high rate is also possible when the network is free. 

Unspecified bit rate. It does not provide any fixed throughput level and it is best for the file transfer where delay can occurred.

ATM ADVANTAGES

It provides fixed bandwidth and simple routing is possible due to the connection oriented technology. High bandwidth utilization can be possible so it is the best solution for the telecommunication sector, videoconferencing and QOS. There are some of the disadvantages of this technology such as high cost, cell loss due to the high congestion in the network.

Common Errors & Symptoms of damage to the hard drive

The following are the common symptoms are problems that are associated with the hard disk failure.

• Missing Power or data cable.


• Incorrect BIOS configuration.


• Incorrect Hardware configurations.


• Devices Conflict.


• Data cable is not connected.


• Drive not powered on.


• Port disabled.


• Power supply might no be connected to the hard disk.


• Missing operating system and hard drive boot failure message appear.


• Disk out of space message appears.


• No boot record, no disk found or invalid disk message appear, which indicates that the system boot files are not located on the root directory.


• Hard disk controller failure message appear.


• Display is present on the screen and front panel lights are also visible but there is not boot up.

Solutions:

While booting up the computer observe the BIOS’s hard disk configurations and information. Make sure that the system BIOS is displaying the exact information of the installed hard disk and there is no devices conflicts. Check the master/slave jumper settings and if you have attached more than one device to the same interface cable then make sure that all the devices are of the same type. If you cannot access the hard drive even its configurations and BIOS settings are correct then the problem must be in the components that are associated with the hard disk.  These components include drive, signal cable and hard disk controller.

For troubleshooting the cables related errors, unplug all the cables from the hard disk and plug them back.  For configurations related errors, check the system BIOS and make sure that it’s displaying the exact information and settings of the hard disk. 

Any kind of noise indicates the mechanical problems, which may be associated with the hard disk plates or any other components.  Replace the hard disk with new one.

No boot record found, disk failure, invalid disk and “NTLDR missing” errors indicates that either the operating system is not installed on the root directory or it has been corrupted.  Repair the operating system with the recovery disk or install new operating system.

To troubleshoot the surface errors of the hard disk run the following two commands one by one at the command prompt and press enter.

Scandisk

CHKDSK

These commands will check the hard disk for possible errors and troubleshoot them.

Troubleshooting USB Device

• Make sure that you have the latest software installed on your computer because if the software doesn’t have the latest components then the devices can cause problems. 


• Visit the manufacturer’s website to see any latest drivers for the device.


• Unplug the faulty USB device and plug it back.


• Unplug all the USB devices from the computer such as USB drive, USB keyword, USB mouse etc and then plug them back one by one.


• If it’s a new USB device then replace it with another and if it’s an old one then figure out the changes that you did just before the device stopped working.  Did you install any new hardware or software?


• Check the USB device with all the USB ports of the computer and see if it works with any port or not?


• Check the USB device with the other computer and see if it works fine with it

Is the Friend's WAN network?

A WAN (Wide Area Network) is a data communication network that covers a broad geographic area.  The term WAN applies to the broader telecommunication infrastructure.  Router is the main communication device in the WAN networks. How WAN Works? A WAN is a network of interconnected devices such as router, switches, modems, wireless devices, DSL services, frame relay devices, access servers, ISDN terminal adapters, DSU devices and WAN switches.  The most common WAN circuits are packet switching, circuit switching and point to point communication.  In WAN routing the routing table contains the IP addresses of the source and destination devices.  On the basis of the routing table, the router chooses the best possible shortest path for the packets.

A point to point link is also known as a leased line and which provides the communication between two remote locations through a carrier network such as Telecommunication Company.  In circuit switching a carrier network is involved in establishing, maintaining and terminating communication session. In packet switching, the communication devices share point to point link to transfer packets from the source and destination. Dial-up services provide cost effective solutions for WAN connectivity.

WAN Technologies

The WAN technologies operate at the lowest level of the OSI layer model.

ATM

ATM or Asynchronous Transfer Mode is a high bandwidth and high speed wide area network technology that operates at the speed of 155Mbps.  ATM is also called cell relay and it supports multiple data types such as data, voice, video etc.  ATM uses fixed sized packets for data communication that are also known as packets.

Dial UP

Dial up WAN provide the cost effective communication solutions.  Dial up demand and dial up backup is the two WAN dial up services.  In a DDR, a router dynamically initiates a call on a switched circuit when it requires sending data. 

In dial backup, switched circuit is used to provide the backup services for other types of networks such as PPP or packet switching.

X.25

X.25 is a data communication protocol in the packet switched networks.  X.25 allows computers at the remote locations to communicate with each other through a centralized computer.

Frame Relay

Frame relay is a very high speed and high performance WAN protocol.  Frame relay operates at the physical and data link layers of the OSI model.  Frame relay is a networking method that is designed for the data transmission between LAN and WAN.

ISDN Lines

Integrated Services Digital Network is a WAN communication method over the regular telephone lines.

Circuit Switching

In WAN, when a router has data for the remote site the switched circuit is initiated.  When two remote networks communicate and authenticate then the communication starts.  ISDN is the best example of the circuit switching network.

Packet Switching

In packet switching the common carrier resources are shared between the remote networks.  ATM, Frame Relay and X.25 are the examples of the packet switched networks.  In this technology, the network has connections into the carrier networks and some portion of the carrier network is shared.

CSU/DSU

Channel Circuit Unit/Digital Circuit Unit is a device that is used to connect a router with the digital circuit like T1.

WAN Routing

WAN routing is a technique of forwarding the packets towards the destination based on the IP address of the next hop.

Every Bluetooth enabled devices such as mobile phones, laptops, digital cameras, video games consoles have built-in microchip. There are about more than 1800 members of the Bluetooth consortium from all over the world. Every GSM and CDMA mobile operates must provide the features of the Bluetooth technology to its users. Like the Bluetooth, Wi-Fi uses the same frequency but the power onsumption f th wi-fi is high so it produces more powerful signals.

Setting Speedy Modem ADSL Sebagai Bridge Di OS LINUX

Telkomspeedy lauching pertama kali di Jember, kota di mana saya bekerja, sekitar bulan Juli 2006. Saat itu saya belum pernah merasakan internet dengan speedy, tahu-tahu diminta bos untuk membantu men-setup modem adsl di Kopegtel (Koperasi Pegawai Telkom) di jalan Kartini. Modemnya merek linksys, tipenya mungkin ADSL2MUE, pada link tersebut terdapat manual untuk konfigure modem tersebut untuk mode bridge (winxp).

Pertama, saya minta manualnya, kemudian baca2 sebentar dan akhirnya tahu bahwa modem adsl ini berfungsi sebagai router dan bisa dicolokkan langsung ke swicth/hub untuk melayani koneksi internet bagi semua komputer yang terhubung keswicth/hub, asal fungsi dhcp clientnya diaktifkan.

Berhubung cukup lama mainan iptables di mesin linux, saya coba lihat apakah ada fungsi firewall di modem tsb. Setelah login melalui web configuration, saya lihat banyak sekali fitur yang ditampilkan sampai saya bingung sendiri 

Yang pertama saya baca-baca adalah seting koneksi untuk speedy, tidak ada yang saya mengerti di sini  , kecuali login speedy dan ini dia fungsi bridge, jadi modemnya bisa berfungsi sebagai bridge mirip modem eksternal yang biasa dipakai untuk dial ke isp. Pokoknya diterima apa adanya dulu deh. Lantas saya lihat fungsi firewall, nah ini dia yang bisa saya otak-atik. Yang diinginkan pertama adalah mencegah icmp dan smtp keluar dari client karena virus brontok suka ping ke domain internet dan mencegah virus dari client kirim email. Selain itu juga saya batasi hanya beberapa ip client yang bisa konek internet. Setelah save dan reboot modem, ternyata hasilnya mengecewakan, beberapa client bisa konek dan ada yang tidak. Saya masih belum tahu salahnya dimana, lagian keisengan setup modem linksys tsb terbatas waktunya karena saya harus balik ke kantor dan lagipula saya tidak mau direpotkan apabila dapat keluhan dari pengguna. Jadi saya balikin deh seting modem tsb ke default.

Sejak saat itu saya terobsesi bagaimana membuat modem adsl bisa jalan sebagai bridge di mesin linux. Khusus modem linksys ADSL2MUE ini rupanya sudah ada driver bridge untuk mesin windows. Kesempatan itu akhirnya datang setelah kantor saya jadi berlangganan speedy, itu pun setelah saya provokasi agar pakai speedy daripada pakai telkomnet instan (tni) yang koneksinya tidak bisa dijamin, sudah konek tapi tidak bisa browsing internet, baru bisa browsing setelah beberapa kali konek  . Yang datang ke kantor bawa modem speedy rupanya orang telkom yang dulu saya temui sewaktu di Kopegtel Kartini, karena sudah mengenal saya, dia memberikan saya modem adsl yang masih terbungkus agar disetup sendiri.

Sewaktu dibongkar, ternyata modemnya adalah DareGlobal model DB108-E. Padahal saya pingin dapat yang linksys , alasannya keren karena keluaran Cisco  . 

Saya baca sekilas di manualnya bahwa modem ini mempunyai ip default 192.168.1.1, akhirnya server linux yang biasa pakai modem eksternal untuk konek ke tni dikonfigurasikan untuk client modem tsb. Modem dikonekkan ke link adsl dan ke server linux pakai cross cable, terus dinyalakan. Waktu itu saya belum setup login speedy di modemnya, iseng-iseng nge-ping dns telkom, eh kok ternyata tembus, wah dapat koneksi speedy gratis nich :d .

Masa gratisnya cukup lama, dua minggu lebih. Selama itu saya belum sempat mencoba setup modemnya sebagai bridge, keasyikan download macam-macam, mumpung gratis. Akhirnya masa foya-foya lewat sudah sekarang waktunya bekerja. Berikut ini prosedur setup modem adsl DareGlobal untuk mode bridge:

1. Login ke web configuration modem adsl.


2. Tampilan pertama kali adalah Device Info seperti gambar di bawah (ini saat mode router dan status konek ke internet):
   


3. Tampilan DSL Status seperti pada gambar di bawah:


4. Klik WAN akan menampilkan default WAN Setup (mode router), untuk mengubah ke mode bridge, baris yang mengandung Protocol PPPoEdicawang lantas klik tombol Remove:
   


5. Lalu klik Add akan muncul isian untuk ATM PVC Configuration, isikan seperti contoh di bawah, kemudian klik Next.
   • VPI:[0-255] 0
   
   
   • VCI:[0-65535] 35
   
   


6. Untuk tipe network protocol pilih Bridging dan untuk encapsulation mode pilih LLC/SNAP-BRIDGING, klik Next.


7. Beri cawang pada Enable Bridge Service dan kasih nama br_0_35untuk Service Name, klik Next.


8. Berikut WAN Setup – Summary seperti pada gambar di bawah, klikSave apabila konfigurasinya sudah benar dan reboot modem adsl-nya:
   


9. Tampilan WAN Setup (mode bridge) yang baru akan seperti gambar di bawah:
   


10. Klik Save dan Reboot modem.

Modem adsl telah selesai disetup sebagai bridge, sekarang kita akan membuat koneksi pppoe di linux. Untuk linux redhat 9, nama paketnya rp-pppoe-3.5-2.rpm, untuk slackware 10.2 rp-pppoe-3.6-i486-1.tgz, jika ingin install dari source silahkan download di RP-PPPoE | Roaring Penguin.

Mungkin ada yang bertanya bagaimana mengakses web configurationmodem apabila telah diset mode bridge ? Caranya mudah, untuk ini kita perlu komputer dengan OS windows, install driver yang dibutuhkan untuk koneksi ke modem melalui port usb, kemudian konfigur ip address windows dengan ip addres selain 192.168.1.1. Jadi meski modem tersebut sedang konek ke speedy dan user-user sedang browsing internet kita bisa monitor dsl statusnya.
