IP without IP addresses

D. Phoomikiattisak was funded by the Thai Government. B. Simpson was funded by Cisco Systems under a University Research Programme (URP) grant award.We discuss a key engineering challenge in implementing the Identifier- Locator Network Protocol (ILNP), as described in IRTF Experimental RFCs 6740-6748: enabling legacy applications that use the C sockets API. We have built the first two OS kernel implementations of ILNPv6 (ILNP as a superset of IPv6), in both the Linux OS kernel and the FreeBSD OS kernel. Our evaluation is in comparison with IPv6, in the context of a topical and challenging scenario: host mobility implemented as a purely end-to-end function. Our experiments show that ILNPv6 has excellent potential for deployment using existing IPv6 infrastructure, whilst offering the new properties and functionality of ILNP.Postprin

An API for IPv6 Multihoming

IFIP International Workshop on Networked Applications, Colmenarejo, Madrid/Spain, 6?8 July, 2005This paper proposes an API for Multihoming in IPv6. This API is based on the Hash Based Addresses and Cryptographically Generated Addresses approaches, which are being developed by the IETF multi6 Working Group. The support of Multihoming implies several actions such as failure detection procedures, reachability tests, re-homing procedures and exchange of locators. Applications can benefit from transparent access to Multihoming services only if per host Multihoming parameters are defined. However, more benefits could be obtained by applications if they will be able to configure these parameters. The proposed Multihoming API provides different functions to applications which can modify some parameters and invoke some functions related with the Multihoming Layer.Publicad

Connecting the World of Embedded Mobiles: The RIOT Approach to Ubiquitous Networking for the Internet of Things

The Internet of Things (IoT) is rapidly evolving based on low-power compliant protocol standards that extend the Internet into the embedded world. Pioneering implementations have proven it is feasible to inter-network very constrained devices, but had to rely on peculiar cross-layered designs and offer a minimalistic set of features. In the long run, however, professional use and massive deployment of IoT devices require full-featured, cleanly composed, and flexible network stacks. This paper introduces the networking architecture that turns RIOT into a powerful IoT system, to enable low-power wireless scenarios. RIOT networking offers (i) a modular architecture with generic interfaces for plugging in drivers, protocols, or entire stacks, (ii) support for multiple heterogeneous interfaces and stacks that can concurrently operate, and (iii) GNRC, its cleanly layered, recursively composed default network stack. We contribute an in-depth analysis of the communication performance and resource efficiency of RIOT, both on a micro-benchmarking level as well as by comparing IoT communication across different platforms. Our findings show that, though it is based on significantly different design trade-offs, the networking subsystem of RIOT achieves a performance equivalent to that of Contiki and TinyOS, the two operating systems which pioneered IoT software platforms

Proceedings of Seminar on Network Protocols in Operating Systems

The Linux networking stack tends to evolve rapidly, and while there are some excellent documentation written in the past, most of the past documentation gotten (at least partially) outdated over time. The seminar on Network Protocols in Operating Systems was arranged in Aalto University, fall 2012, Department of Communications and Networking to gain a better understanding of the current status of the networking implementation in the Linux kernel. The seminar had 10 participants and each participant was assigned a module from the Linux networking implementation, on which a short paper was to be written. This publications contain the final output of this work. The papers included in the publication are: Kurnikov, Arseny: Linux kernel application interface.

EMICOM: Enhanced Media Independent COnnection Manager

With the increasing amount of mobile interfaces combining different kinds of access technologies, ranging from Wi-Fi to 3G and LTE, the integration of flexible and mediaindependent link control mechanisms becomes of paramount importance. By employing an abstract way of obtaining access link status information and exercising control over the network interface operations, these control mechanisms become able to optimize device connectivity and network attachment. This paper presents EMICOM, an Enhanced Media Independent COnnection Manager framework where a GNU/Linux Network Manager and Link Service Access Points for the IEEE 802.3 and 802.11 technologies were implemented and integrated through crosslayer Media Independent Handover (MIH) mechanisms from the IEEE 802.21 standard. Through an open-source implementation of the framework, the (MIH) command set capabilities are extended, allowing the support of network association and authentication, as well as Layer 3 services such as IP configuration, providing a generic solution for optimal network connectivity management

Comparing TCP-IPv4TCP-IPv6 network performance

"December 2013.""A Thesis Presented to the Faculty of the Graduate School at the University of Missouri--Columbia In Partial Fulfillment of the Requirements for the Degree Master of Science."Thesis advisor: Dr. Gordon K. Springer.The Internet Protocol version 4 (IPv4) has been the backbone of the Internet since its inception. The growth and success of the Internet has accelerated the consumption of the IPv4 address space and hence its exhaustion is predicted very soon. Despite the use of multiple hidden and private networks to keep things going, a newer version of the protocol, Internet Protocol version 6 (IPv6), is proposed to solve this issue along with many other improvements as part of a better, newer design. For smoother transition and given the decentralized nature of the Internet, both of the protocol stacks, namely IPv4 and IPv6, are expected to be supported by the hosts and hence co-exist for a period of time. Many application programs, especially those involved in large data transfers, currently use the TCP/IP protocol suite. However, there have not been many attempts to leverage the existence of both Internet Protocol versions over a TCP connection. This thesis, through a prototype, is an attempt to improve the network utilization by using either an IPv4 or an IPv6 protocol for a TCP connection based on end-to-end measured performance between two hosts. A measurement tool, named netaware, is developed as part of this thesis to measure the end-to-end network performance for both IPv4 and IPv6 protocols within a single tool. The tool measures two performance parameters, namely the bandwidth and the latency in a multi-threaded environment. The tool utilizes a simple middleware application, also built as part of this thesis, to create and use socket connections for interprocess communication across the network between the two hosts. The middleware application is used as an intermediate level application to take care of creating IPv4 or IPv6 connections between the hosts, needed to transmit measurement and control data while measuring the performance parameters. The use of middleware application facilitates the construction of network applications by having an application developer to deal with minimal code to use either IP protocIncludes bibliographical references (pages 188-190)
