TCP and Link Layer Enhancements in DVB-S/DVB-RCS Satellite Systems

Tags:
tcp - ip

Overview The Transmission Control Protocol (TCP) is efficient on wired networks, but provides poor performance on satellite networks due to the specific characteristics of satellite links. This paper presents the experiments results for a combined approach of a selected set of state-of-art TCP enhancements in conjunction with link layer enhancements. Link layer enhancements consist of a link-aware protocol called Satellite Link Aware Communication Protocol (SLACP), which is designed to improve TCP performance over satellite links. It performs experiments in an emulated satellite DVB-S/DVB-RCS environment with a real implementation of SLACP and TCP enhancements on Linux. Results show that both TCP and link-level enhancements significantly improve TCP performance.

Stanford team in turbo-charged Google claim

Our preliminary experiments show that combining the methods will make the computation of PageRank up to a factor of five faster. The researchers make use of their discovery that on most sites, up to 80 per cent of links point to other pages on the...

What are IP VPNs good for?

While acknowledging IPSec's role in supporting users at satellite offices, BT's Logan says the bulk of big corporate network users are plumping for an MPLS IP VPN, perhaps because it handles voice so well thanks to its prioritisation capabilities.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
