Satellites have been successful in providing infrastructure for broadband telecommunications due to their wide area coverage and ability to speedily deploy new services especially in remote regions of the world. However, over high bandwidth*delay links such as those provided by satellites, Internet applications often exhibit suboptimal performance, which may be attributed to layers of the protocol stack at or above the transport layer. This problem is even more severe when considering future satellite mobile and disaster monitoring applications.
One solution to these problems is to implement a TCP PEP at the transport layer. There are other complementary solutions such as application layer PEPs with data and header compression algorithms and HTTP/DNS acceleration. Commercially available PEPs often combine some or all of these techniques together.
On the other hand many people believe that PEPs break the end-to-end principles of the Internet. Thus implementing end-to-end improvements techniques to TCP, web HTTP and multimedia application are a better solution and avoids the difficult issues related to preventing the use of end-to-end IPsec and end hosts relying on unknown and untrusted intermediate entities (such as PEP proxies).
Papers are invited to this session addressing some of the following areas related to PEPs:
- Tesbed and simulation comparison between PEPs and end-to-end improvements
- Multicast PEP services
- QoS and cross layer techniques to improve PEPs
- Security solutions for PEPs
- PEPs and OBP satellites
- PEP and Delay Tolerant Network (DTN) comparisons
- Performance enhancing in Next Generation Networks (NGN) with satellite components
