Memotec - Redefining Network Efficiency

Mobile Internet Optimization

With the increasing number of smartphones and 2.5G/3G/4G dongle users accessing the Internet, mobile networks are strained with huge levels of data traffic. A direct consequence is a progressively poor user experience and service quality with mobile web services. Operators must address this challenge immediately to avoid customer churn, but network capacity cannot be extended indefinitely!

Memotec xG WebPerformer is an award-winning solution that optimizes mobile web services. Based on TCP session optimization as well as intelligent compression and caching techniques, the xG WebPerformer reduces the bandwidth required to load a web page, to download pictures, and receive webmails or documents. The RAN and network resources are better utilized, ultimately providing better performance.

With its ultra-scalable architecture, the xG WebPerformer is a clientless solution that fi ts with every mobile device. Its unique features allow transparent deployments without any changes in the mobile core network. Highly reliable, the xG WebPerformer can enhance the mobile service immediately without any risk.

xG WebPerformer Features and Applications 

• Throughput: Linear in-service scalability from a few Mbits to several Gbits, more than 1M concurrent TCP connections
• Main Engine: Compression, Caching
• Policy Based Optimization: Individual policy profiles
• Clientless: Browser independent, supports all data subscribers
• TCP Packet Completion: TCP packets are filled to the maximum capacity to reduce overhead and save bandwidth
• http pipe-lining: Dramatic improvement in page load time especially over high latency connections such as satellite
• http "keep-alive": Leverage open TCP connections
• Transparent: No modifications on infrastructure addressing scheme ensures device, application and security interoperability and accelerates deployment
• Browser Database: Browser knowledge base (iPhone, Android, Windows IE) for optimum display on end-user device/screen
• High Availability: Fail-to-wire bypass system provides risk-free operation. Graceful shutdown/restart mechanisms provide seamless operations. Redundant configurations provide +99,999% availability
• Load Balancing: Level 7 load-balancing
• Monitoring: SNMP V2-V3, SNMP Traps
• Management: Web GUI and CLI
• Hardware: Deployed on IBM, Dell or Sun, from 1 to 32+ cores capacity

The powerful http engine processes the downlink traffic and smartly optimizes content according to policy profiles and to browser capability. The latter can then reprocess the minimized information. TCP packets are maximized, TCP connections that are already open are reused, avoiding the opening of a new connection. http 1.1 also allows multiple http requests to be issued without waiting for the corresponding response.

xG WebPerformer’s conception allows it to be deployed in a transparent mode in the network. The failover capabilities allow hot/stand-by deployments.  Combined with the fail-to-wire feature, availability is above 99.999%. Running on most recent multi-cores hardware, xG WebPerformer’s parallel processing architecture can reach more than 10GB per unit which can be cascaded to increase throughput.
