It has been forty years since TCP/IP was standardized as RFC 793. The spectacular success of the Internet has validated the design choices of its protocols and architecture. However, the evolution of the services and applications running over the Internet, new societal requirements and the general unavoidable obsolescence of any protocol will at some point require rethinking the current protocols and potentially replacing them with new ones. New technology has emerged in limited domains networks, such as data centers, that may hint at a way forward for the overall Internet architecture. We present an overview of the recent and current work on post-IP networking and discuss the drivers and motivations that will push us to reimagine IP.

“…Selectively trimming the packet, rather than the whole payload, offers a less drastic mechanism that would work in the wide area network. For enhancing end-to-end transport, a new transport protocol is defined QUCO [18], which reacts to congestion by selectively dropping parts of a payload packet (combined with mitigation mechanisms to handle the loss of part of the payload). Their scheme reduces the variation in the number of packets going through the network, and has less delay and less delay variations than TCP, with a resulting reduction in jitter.…”

This paper describes the effects of running innetwork quality adaption by trimming the packets of layered video streams at the edge. The video stream is transmitted using the BPP transport protocol, which is like UDP, but has been designed to be both amenable to trimming and to provide low-latency and high reliability. The traffic adaption uses the Packet Wash process of BPP on the transmitted Scalable Video Coding (SVC) video streams as they pass through a network function which is BPP-aware and embedded at the edge. Our previous work has either demonstrated the use of SDN controllers to directly implement Packet Wash, or the use of a network function in the core of the network to do the same task. This paper presents the first attempt to deploy and evaluate such a process in the edge. We compare the performance of transmitting video using BPP and the Packet Wash trimming, against alternative transmission schemes, namely TCP, UDP, and HTTP Adaptive Streaming (HAS). The results demonstrate that providing traffic engineering using in-network quality adaption using packet trimming, provides high quality at the receiver.

This paper describes the effects of running in-network quality adaption by trimming the packets of layered video streams at the edge. The video stream is transmitted using the BPP transport protocol, which is like UDP, but has been designed to be both amenable to trimming and to provide low-latency and high reliability. The traffic adaption uses the Packet Wash process of Big Packet Protocol (BPP) on the transmitted Scalable Video Coding (SVC) video streams as they pass through a network function which is BPP-aware and embedded at the edge. Our previous work has either demonstrated the use of Software Defined Networking (SDN) controllers to implement Packet Wash directly, or the use of a network function in the core of the network to do the same task. This paper presents our effort to deploy and evaluate such a process at the edge, highlighting the packet trimming algorithm and showing the packet trimming effects on the streams. We compare the performance of transmitting video using BPP and the Packet Wash trimming, against alternative transmission schemes, namely UDP and HTTP adaptive streaming (HAS), presenting a number of quality parameters. The results demonstrate that providing traffic engineering using in-network quality adaption using packet trimming, provides high quality at the receiver.
