Gigabit Classification and Management of Annoying IM/P2P Bandwidth
Internal/External Bandwidth Problems
Peer-to-Peer (P2P) and Instant Messengers (IM) have become the major Internet applications.
People often use Outlook to receive emails, Internet Explorer to browse websites, IM such as MSN/Skype to communicate with friends, and P2P such as KaZaA/BitTorrent/eMule to download files. With effective management, IM/P2P can be a very good communication medium. However, P2P often consumes a huge amount of bandwidth. "Eat-all-you-can-eat" style of bandwidth consumption makes internal networks and external networks face the challenges. Bandwidth at external networks is occupied by P2P so mission-critical applications cannot obtain adequate bandwidth. Internal subscribers compete for the limited bandwidth at external networks, causing unfairness among the internal subscribers. For telecom operators and campus network administrators, simutaneously solving internal and external bandwidth problems becomes the most critical demand.
Tough IM/P2P: Difficult to Recognize by Layer-4 Port Numbers
Organizations that emphasize network performance may have deployed L4 bandwidth management systems. BT / Xunlei / FlashGet / MSN / Yahoo / ICQ / AOL / Skype / Google Talk can emulate themselves to behave like web or email to cheat firewalls, tunnel through proxy servers, or even encrypt themselves with SSL. Network administrators cannot manage them completely.
Layer-7 Solution: InstantQoS Bandwidth Manager
L7 Networks' InstantQoS Bandwidth Manager is based on DPI (Deep Packet Inspection) with the patent-pending SoftASIC® acceleration technology. The granular usage statistics gathered by InstantQoS throughout the network are transformed into a complete array of meaningful "network intelligence" by L7's central network management system. Tens of real-time, interactive graphs, charts, and reports show who's doing what on the network - right now and over time - giving service providers the tools they need to drill down into individual traffic flows and to control service delivery according to service level agreements.
World-Leading Architecture : 3-Tier Inline-Mode
InstantQoS applies 3-tier architecture and uses independent management port to accept configurations or to send logs to the management server for further reporting. Administrators can open browsers anywhere to connect to the server to setup the device or to view top reports.
Fast Update, Global Service :
L7 Networks has teams of security experts that cooperate with strategic partners and use global update
mechanisms to update pattern/engine/virus database for fast update service.
