An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking

Abstract

We propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with current IP-based networks. Without introducing complex operations, the resulting E2E-ERN protocol provides inter and intra protocol fairness and benefits from all ERN advantages when possible. We detail the principle of this novel architecture, called IP-ERN, and show that this architecture is highly adaptive to the network dynamics and is compliant with every TCP feature, IPv4, IPv6 as well as IP-in-IP tunneling solutions. As a possible use case, we test this architecture as a potential candidate to replace Performance Enhancing Proxies (PEPs) commonly-used over satellite IP-based networks. Compared to splitting PEP, the IP-ERN architecture does not break the E2E connectivity, still achieves high satellite link utilization and fairness without needs of extra fault tolerant mechanisms.

“…To adapt the congestion control and data rate transmission to a specific SATCOM scenario, more important modifications may be required. They may involve changing the advertised receive window, such as in IP-Explicit Rate Notification (IP-ERN) architectures [20], delegate the security to the network operator for better quality of experiences or update the browser [27]. These specifications could be negotiated at initialization such as discussed in the transport draft of IQUIC [9].…”
