End-point Synchronisation and Handover for Multi-homed Services
نویسندگان
چکیده
It is proposed to implement a synchronised routing table at the transport layer, referred to as an Association Routing Table (ART), to improve the performance of multi-homed transport protocols. An algorithm is described that ensures that the routing tables can be synchronised, which is then used to implement a handover mechanism. The ART is implemented within SCTP. It is shown that by using a synchronised ART, it is possible to implement failover in cases where standard SCTP cannot, configurations are more resilient to network errors, and it is possible to perform a handover without any network support.

Path Management and Selection in Heterogeneous Wireless Networks
This thesis addresses path management issues for multi-homed nodes with access to multiple heterogeneous wireless networks. The challenge in this environment is to provide mobility between networks, that is to move seamlessly between networks while providing the best possible service to applications. This thesis addresses both issues using an Association Routing Table (ART) located at the trans...
متن کاملMulti-path Transmission, Selection and Handover Mechanism for High-Quality VoIP
With the development of audio encoding standards and IP technology, voice over IP (VoIP) is becoming quite popular. However, high-quality voice data over current networks without QoS Support, such as Internet and UMTS, still posses several challenging problems because of the adverse effects caused by network bandwidth restrictions and complex dynamics. One approach to provide QoS for VoIP appli...
متن کاملEnd-point Identifiers in Secure Multi-homed Mobility
Currently IP addresses are used both for node identifiers and topological location names in the Internet. The semantic overloading and non-cryptographic nature of IP addresses makes it impossible to use them as identifiers from the security point of view. The problem becomes even worse with multi-homed mobile nodes. Multi-homed mobile nodes have several interfaces bound to dynamically changing ...
متن کاملAn Adaptive Optimized RTO Algorithm for Multi-homed Wireless Environments
As a transport layer protocol SCTP uses end to end metrics, such as Retransmission Time Out (RTO), to manage mobility handover. Our investigation illustrates that Wireless LAN (WLAN) mobility causes continuously increased Round Trip Times (RTT) resulting from 802.11 MAC retransmissions, regardless of the service specified by upper layers. We present scenarios where the current understanding of ...
متن کاملHandover Cost Optimization in Traffic Management for Multi-homed Mobile Networks
In this paper, we study the traffic management problem for multi-homed mobile networks with the objective of minimizing the overall handover cost. Two different traffic distribution modes are considered in our study: the Fractional Flow Assignment (FFA) mode which assumes the bandwidth demand from one connection is infinitely splittable and can be assigned to different wireless access networks,...
