Flash Networks announced that it is the".. first mobile optimization vendor to accelerate upload speeds for messaging apps such as WhatsApp and Snapchat. Flash Networks uses patented technology to optimize LTE bandwidth utilization, resulting in up to 30% faster upload speeds for an improved user experience.
Flash Networks’ TCP-4TE [see chart below for download optimization] uses inline high-speed congestion-detection algorithms to dynamically adjust transmission rates based on real-time network conditions to enable faster uploads of content to messaging services. TCP-4TE minimizes the inherent inefficiencies of standard TCP stack, making its data transmission methods more compatible with high-speed LTE networks".
