This paper proposes a simple path diversity algorithm (SPDA) for Interdomain routing. The SPDA uses source routing to find an alternate path from a source to a destination, and allows flexible division of traffic over the best and alternate path. The SPDA comprises three steps. First, the BGP protocol is extended to allow the BGP routing table to save the multiple paths for any destination. Second,...
This work presents a study of RTP multiplexing schemes, which are compared with the normal use of RTP, in terms of ITU R-factor quality estimator. The bandwidth saving of the different schemes is studied, and some tests with VoIP traffic are carried out in order to compare R-factor using three different router buffer policies. Network delays are added using an adequate statistical distribution. The...
The aviation community is currently working on the standardization of data communication systems for the future air traffic management. In this context, the ICAO and EUROCONTROL are working on the standardization of IP-based aeronautical telecommunications network and future radio access technologies, respectively. With this work, for the first time, we integrate L-DACS 1, which is one candidate for...
Micromobility protocols have been proposed to provide seamless local mobility support. There are several micro mobility protocols such as HMIP, Cellular IP and HAWAII. This paper focuses on the performance of single stream forwarding scheme of HAWAII . An analytical model is developed for the evaluation. The aim of the paper is to investigate the impact of the buffering at the old base station on...
At present, many studies focus on the efficiency of handoff among different networks, while research on how to maintain the safety during registration process of handoff is not enough. Unfortunately, mobile node is vulnerable to various security threats and attacks when handover for being lack of protection. A security scheme based on the IPSec protocol which was combined with fast handoff signaling...
MIPv6 is one of the dominating protocols that enable a mobile node to maintain its connectivity to the Internet when moving from one access router to another. However, it suffers from long handoff latency and routing inefficiency. In this paper, we present a novel distributed mobility management scheme, ADA (Asymmetric Double-agents Architecture), which introduces two mobility agents to serve one...
The inherent support in routers (SNMP counters or NetFlow) is not sufficient to diagnose performance problems in IP networks, especially for flow-specific problems and hence, the aggregate behavior within a router appears normal. To address this problem, in this paper, we propose a Consistent NetFlow (CNF) architecture for measuring per-flow performance measurements within routers. CNF utilizes NetFlow...
Media-Independent Pre-Authentication (MPA) is used as a secure handover optimization scheme working over any link layer. With MPA, a mobile node (the MN) can establish a security association with a candidate target network (CTN), obtain an IP address and other parameters from the CTN, and complete the binding update of any mobility management protocol with the new care-of address (nCoA) before performing...
Mobile multicast becomes a research hotspot with the development of wireless and mobile technologies, and it is based on the traditional multicast protocols and mobility management protocols to provide the multicast services for mobile subscribers. Several mobile multicast methods were proposed in the past few years, but most of them are based on the mobile IPv6 and its alternatives which require...
This paper propose a novel approach to utilize the network to store data in form of floating IP packets. Network could play the role of temporary storage in certain applications and packets could be retained in the network in a closed routing loop. This approach which is called Data Storage Technique on IP Networks (DSTN) could be considered as one of the new applications of future IP networks. With...
Traditional Internet faces many challenges, ranging from security threats, routing scaling problems to inadequate support for mobility, multihoming and traffic engineering. This paper proposes a clean-state network-based architecture, named identifier separating and mapping architecture (ISMA), to solve these problems. The key design concepts of ISMA include separating customer networks from the core...
The communication between wireless ad-hoc networks and infrastructure-based networks is essential to extend Internet beyond its traditional scope, to remote inaccessible areas, making Web services in ad-hoc networks available anytime, anywhere. The mobile nodes in a wireless ad-hoc network must be able to detect available gateways and select one of them if they want to have Internet access. In this...
With the development of mobile technologies several mobile multicast methods were proposed, but most of them are based on the host-based mobility support specifications such as Mobile IPv6 (MIPv6) which require the mobile hosts to support the mobility function. Recently, the Proxy Mobile IPv6 (PMIPv6) was proposed to provide the mobility support for mobile node without mobility function, and the previous...
This paper preliminarily examines the applicability of Internet protocol (IP)-related communication technologies such as IP and MPLS (multi-protocol label switching) routers and L2 (layer-two or Ethernet) switches to existing teleprotection systems. The teleprotection systems concerned include microprocessor-based current differential teleprotection with data communications of instantaneous current...
Network mobility (NEMO) supports the movement of some part of the network that a group of the mobile nodes (MNs) or the mobile routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed. In the nested mobile network, however, the NBSP exhibits pinball routing problem. As the degree of nesting increase, the problem becomes more serious. In this paper, we propose...
This work addresses the development of an ECN-based MBAC algorithm for use over HAIPE. The proposed MBAC resides at the red enclaves, but leverages the ECN, which is defined in RFC 3168 and can be activated at the existing black routers. With these MBAC capabilities, ad-mission control policies are generated at the red enclaves to react to the black core congestion without the need to pass information...
In this paper, we propose a packet multiplexing technique with flow aggregation based on BGP routing information for slotted optical packet switching (OPS) networks and evaluate its performance.
Explicit congestion notification (ECN) is a mechanism that can be used to provide early indication of impending Internet congestion, and as such can be used to reduce the latency and improve the throughput of applications using the Internet. This paper examines the impact of using ECN with quality of service classification for Internet paths that include a satellite delay. Specifically, it provides...
In this paper we present an idea for guaranteed performance in real time video communication with error resiliency. The idea carries three main concepts called connection establishment with user defined performance parameters, back pressure re-routing and error resiliency by feedback control. The performance parameters we consider here are time delay and bandwidth. Establishing a connection that gives...
Multi-homing has been widely adopted in todaypsilas Internet. Several solutions have been proposed to support multi-homing, and Shim6 became most promising for IPv6-based next generation Internet. This paper proposes a Shim6-based dynamic path-selection mechanism, which selects path adaptively to earn higher bandwidth utilities and better performance. The experiment result shows that the new mechanism...
