Mobile Internet Optimization & Acceleration
Wire-speed Traffic Inspection and Granular Classification for Differentiated Mobile InternetData Acceleration
Content Inspection Director
® (CID) transparently intercepts, inspects and performs wire-speed classification by Layer 2-7 criteria. Employing subscriber handset, application and content classification and service attributes (RADIUS sniffing), CID makes it possible to intelligently route traffic to relevant compression, acceleration or caching services. By identifying granular mobile data service needs, CID enables differentiated traffic handling and best-fit mobile Internet data service acceleration.
Operating as a WTCP-TCP gateway, Radware’s solution dramatically accelerates transmission control protocol (TCP) speed across the mobile radio access network (RAN). By splitting end-to-end TCP connections into two parts, AppDirector™ shields the problems of the wireless link from the wireline Internet path and vice versa, making it possible to address key differences in TCP latencies, packet loss and congestion across networks.
WTCP-TCP Gateway for Adapted and Truly Convergent Mobile Internet
The CID-AppXcel™ WTCP-TCP gateway makes TCP aware of service loss across the RAN. By managing end-to-end TCP packet transmissions across wireline and wireless links, the gateway controls TCP service reliability and transmission integrity. The CID WTCP-TCP gateway also affords full support of transactional TCP (T/TCP), extending the benefits of T/TCPs from wireline to wireless networks. These include enhanced reliability and speed, along with reduced bandwidth consumption, for short transactional sessions including World Wide Web, remote procedure calls and DNS requests.
TCP Network Transport Optimization for Consistent QoS and Accelerated Performance
AppXcel optimizes TCP protocol transmission over wireless networks employing multiple techniques to overcome TCP inefficiencies. It manages TCP session initiation, eliminating the negative impact of slow session starts. AppXcel controls TCP handshakes and TCP transmission window size, including increased initial window size, packet reordering, maximum transmission unit and packet size definition to eliminate congestion and service latencies. By managing TCP session acknowledgement, error handling and retransmission decisions, AppXcel further increases TCP session efficiency and reliability. AppXcel TCP header compression and IP payload compression coupled with active queuing management are also employed to accelerate TCP transmission and reduce bandwidth consumption. With AppXcel, mobile carriers can mitigate inherent TCP transmission inefficiencies, eliminating their negative impact on mobile data services for faster subscriber access and quality of service (QoS) while improving link bandwidth utilization loss to reduce the cost per bit of information delivered, reducing OPEX.
Advanced Web Compression for Improved Response Times and Reduced Data Flow Bandwidth Consumption
AppXcel employs industry-leading compression techniques for on-the-fly compression of mobile data traffic. AppXcel uses loss-less compression techniques to handle plain text, HTML, JavaScript and content style sheets (CSS) mail attachments and HTTP/SMTP headers, reducing the amount of data being transferred for up to 700% improvement in mobile Internet web page loading times.
Image Compression and Manipulation for Best End-user Performance
To expedite image retrieval, AppXcel image compression employs industry-leading image manipulation algorithms for up to 90% file size reduction for already compressed graphic formats, such as JPEG, enabling these for mobile devices. AppXcel’s built-in caching further accelerates media retrieval for frequently requested images, boosting delivery speeds, while significantly reducing bandwidth requirements to cut mobile network rich media service scaling and operating costs.
Smart Caching for Optimal Delivery of Frequently Retrieved Content
CID analyzes subscriber application and content requests by Layer 4-7 information (including URLs) and selectively directs subscribers to AppXcel units for the serving of cached content. By extending caching services from within the Gi network, CID dramatically reduces delivery times across subsequent user requests for the same content, accelerating response times while reducing overall bandwidth consumption by eliminating unnecessary network congestion. CID’s unique smart traffic routing makes it possible to maximize the storage of cached content in each AppXcel farm, while ensuring highly accurate caching services, preventing caching overlap for highly economical cache service growth.
Scalable, Best-of-breed Service Growth through Seamless Component Addition
CID enables the redirection of traffic to any new compression component by any Layer 2-7 criteria, for seamless addition and full interoperability of best-of-breed acceleration tools. Affording a unified service delivery platform, CID’s flexible component addition lets carriers economically grow their content security services to match new business models, or meet growth in customer demand, without requiring investment in new infrastructure, for CAPEX savings and ROI.
Full End-user Transparency
Radware’s mobile acceleration does not require any client installation for fully transparent operation and seamless operation across all end-user devices.
Carrier-grade Performance, Network Transparency and Fault Tolerance
CID and AppXcel are designed for carrier-grade performance, availability and scalability requirements, capable of handling up to 2,000,000 concurrent sessions for unlimited service scaling to handle growth in mobile data and subscribers.
CID supports multi-GGSN configurations for seamless integration in mixed vendor environments. CID may be installed as either a bridge or a router and operates as a transparent device, supporting all network tunneling protocols and encapsulations including MPLS, L2TP, GRE, GTP and PPP, for seamless operation across any carrier network.
