TCP Acceleration

Take your network to the next level by taking control of TCP

TCP acceleration allows communications service providers (CSPs) to dramatically improve network efficiency and subscriber quality of experience (QoE), without making changes to the network infrastructure.

In today’s networks, TCP’s very nature causes problems:

  • When additional bandwidth is available, TCP may not be fast enough
  • When too little bandwidth is available, TCP may be too fast
  • When there are many concurrent TCP connections, the collection as a whole behaves inefficiently

For CSPs, these problems have two significant consequences:

  1. Network efficiency is harmed, causing performance return on investment to fall below expectations
  2. Subscribers are dissatisfied, due to poor application quality of experience

Improving Network Efficiency and Subscriber QoE with TCP Acceleration

TCP acceleration allows communications service providers (CSPs) to dramatically improve network efficiency and subscriber quality of experience (QoE), without making changes to the network infrastructure.

In this session, you will learn how to:

  • Increase network performance for any access network
  • Improve subscriber quality of experience
  • Increase revenue opportunities
  • Drive rapid ROI

The Sandvine TCP Accelerator is engineered to make TCP run better in today’s networks:

  • When additional bandwidth is available, TCP Accelerator ensures TCP doesn’t become a bottleneck by accelerating the slow-start phase and by making sure there is always enough data ready to be served
  • When too little bandwidth is available (e.g., from congestion, spotty mobile coverage, or a low-speed service plan), TCP Accelerator reduces effective latency by preventing bufferbloat in access network resources
  • By transparently bridging the access network with the transit network, TCP Accelerator is in a position to manage all the network’s TCP connections as a collective whole, to ensure maximum efficiency

This table shows speed-up results (i.e., how much faster data was transmitted) in one customer’s LTE network.

TCP Optimization: Opportunities, KPIs, and Considerations

By truly understanding the ways in which TCP performance can be optimized, the KPIs by which these optimizations can be measured, and the related considerations, a CSP will be in a position to make an informed decision and choose the most suitable solution.
