Encryption WPA (Wi-Fi Protected Access) should be tough right? However, Japanese scientists had only takes 60 seconds to penetrate the WPA encryption used in wireless router. Note this time brought down the previous record for 15 minutes. Toshihiro Ohigashi from Hiroshima University and Masakatu Morii of Kobe University will reveal how they do over at a conference in Hiroshima 25 September next. This inroad is not given full control of Wi-Fi connection, but allows the reading and spoofing packets.
But the ease of penetrate WPA encryption TKIP (Temporal Key Integrity Protocol) to make that anyone who cares about security should start thinking to move to WPA2 with AES encryption (Advanced Encryption Standard) which is more secure. The attack was carried out on a PC and Wi-Fi Access Point that were located far enough away so that the two devices see each other indirectly. Computer attacks carried out between them by acting as a relay using the correct checksum to trick the network. The good news, until now WPA2 with AES encryption newer remain safe from attacks by hackers.

Service-Driven Networks for Next Generation Technology

One the of first announced customers for the AT&T Synaptic Hosting Service is the U.S. Olympic Committee (USOC), which has powered the teamusa.org Website with AT&T Synaptic Hosting. Given the buildup of Website activity leading up to and during the Beijing Olympic games and the subsequent fall-off in activity in the months following the games' conclusion, the flexibility enabled by the utility computing model was ideal for the USOC.
Network operators around the world face tremendous challenges and opportunities as they transform themselves from traditional telcos of the 20th century to the next-generation communications providers of the 21st century. As network services and network traffic migrate from TDM, voice-to-packets, and IP, network operators have no choice but to transform themselves or decline and, ultimately, fail in this new and highly competitive environment. As network operators, the network must play a primary role in this telecom industry transition. Clearly, this explains the unveiling of various network operator NGN initiatives around the world over the past couple of years. At the network level, key requirements for operators to realize this
vision of the future include:
• End-to-end connection and resource management
• Ubiquitous connectivity between networks
• IP-aware transport
• Increased service awareness in access and metro
• Service-aware data, control, and management planes
• High availability
• Network flexibility
• On-demand connection abilities
Despite much talk about NGNs, the industry is still in the early stages of this transformation. We will see a great deal of change over the next decade and beyond. The winning network operators will be those able to successfully embrace today's data/IP growth applications, adapt quickly to deliver the as-yet unknown applications that will drive revenue growth in the future, and build the bridge between legacy TDM and packets, as long as TDM continues to exist in the network.

Jaringan Akses Broadband
Jaringan akses merupakan jaringan yang menghubungkan perangkat pemakai akhir/end-user’s ke jaringan inti/core network, konten dan server aplikasi. Jaringan akses ini mencakup jarak pertama (first mile) ke pelanggan dan jarak kedua (second mile), yang memberikan distribusi layanan yang bervariasi. Jarak pertama/first mile menghubungkan pelanggan tetap atau terminal bergerak/mobile terminal ke titik akses pertama yang disebut DSLAM/base stasiun dan memberikan pipa bandwidth ke pelanggan.
Medium transmisi untuk akses bergerak/mobile akses ini menggunakan radio interface yang disebut sebagai udara. Untuk akses dengan menggunakan jalur kabel, dipakai kabel tembaga atau serat optik (Fiber Optics). Maksimum bandwidth setiap pelanggan bervariasi, tergantung pada berapa banyak pelanggan yang terhubung ke titik akses, jarak antara terminal pelanggan, titik akses, medium pengiriman yang digunakan dan frekuensi yang dipakai.
Ketentuan teknologi akses pertama jarak pertama/first mile memberikan bandwidth, distribusi layanan, dan aplikasi untuk setiap pelanggan. Jarak kedua/second mile merupakan jarak beberapa km dari titik akses jarak pertama, yang di hubungkan ke jaringan inti yang disebut sebagai backhoul. Ada beberapa teknologi untuk titik akses, dimana pada jaringan modern, medium transportasi menggunakan protokol ethernet dan fiber optik yang mempunyai kapasitas bandwidth yang besar.
Teknologi yang diwariskan seperti ATM, TDM-based SDH dan multi-service yang memberikan platform sebagai teknologi radio tanpa kabel yang menggunakan gelombang mikro (Microwave Frequencies) atau widespread. Jaringan harus memiliki standar carrier-grade, dimana jaringan tersebut sangat dipercaya dan mendukung perbedaan quality of service (QOS). Juga dapat mengatasi berbagai tarif seperti volume tarif dan flat rates.
