A Named Data Networking (NDN) router can maintain a record in its PIT for every Interest packet and leverage PIT table to achieve the goal of stateful forwarding. In this paper, a more general application scene that presents new challenges for stateful forwarding is considered. The network element needs to keep states of previously forwarded packets to determine the forwarding behavior of subsequent...
This paper addresses one serious SDN-specific attack, i.e., data-to-control plane saturation attack, which overloads the infrastructure of SDN networks. In this attack, an attacker can produce a large amount of table-miss packet_in messages to consume resources in both control plane and data plane. To mitigate this security threat, we introduce an efficient, lightweight and protocol-independent defense...
Network Virtualization Overlays (NVO3) provides multi-tenancy services in cloud data centers with existing networking equipment. IP tunneling is an essential technology to logically separate each virtual traffic, in particular, Stateless Transport Tunneling (STT) is considered to achieve better performance using TCP Segmentation Offload (TSO) feature. Currently, there is no openly available implementation...
Software-Defined Networking (SDN) is widely studied in research community. Although OpenFlow switches are considered one of the promising SDN technologies, even the latest version of OpenFlow (1.3) only handles 40 tuples including Layer 2 to Layer 4 (L2–L4) headers. However, application developers and end users may not often find "flow" based traffic control. In this paper, we propose L7...
The development of wireless technologies makes it necessary to find a way of improving Transmission Control Protocol (TCP) efficiency with regards to optimal utilization of wireless channel capacity. This paper describes a modification to the TCP congestion control for use in wireless sensor networks. It shows that by slightly modifying the algorithm of the TCP, it can be made to respond better to...
We present a method of accelerating the execution process of read/write requests for the implementation of the iSCSI virtualization switch used in the SANs. Improving the read/write speed of iSCSI network protocol is important in its storage systems. Hereby, we propose a method for accelerating read/write requests by introducing an iSCSI virtualization switch which is facilitated by a transfer-sycro-control...
We propose a primary path switching scheme to provide a seamless handover for dual-homed mobile terminals. This scheme is suggested as an enhancement to the mSCTP protocol. With our scheme, a mobile terminal performs primary path switching before it becomes unavailable due to its primary path drop. The improvement of the scheme comes from considering the temporal velocity of the mobile terminal with...
The aim of this study is to quantify performance of network file transfer for research testbed. This study was carried out because Internet users nowadays has surfing tendency to stream video, download and upload video which need more Internet bandwidth. In addition, there is also a requirement for clarification between theoretical and actual performance of Internet Protocol version 6 (IPv6). This...
OpenFlow is an open standard that can be implemented in Ethernet switches, routers and wireless access points (AP). In the OpenFlow framework, packet forwarding (data plane) and routing decisions (control plane) run on different devices. OpenFlow switches are in charge of packet forwarding, whereas a controller set up switch forwarding table on a per-flow basis, to enable flow isolation and resource...
Ensuring a seamless connection when users are moving across radio cells is essential to guarantee a high communication quality. In this paper, performance of TCP during the handover in a Long Term Evolution (LTE) network is investigated. Specifically, mobile users with high bit rates TCP services are considered, and the impacts of the intra LTE handover over their perceived throughput are studied...
Nowadays, the real practice of network coding in wireline networks is focused on the P2P overlay networks. Although it can help to utilize network resources more efficiently, P2P network coding does not exhibit benefits in terms of the maximum throughput. Our work aims to implement network coding at the IP layer, which is an idea not fundamentally new, but with little real practice because of the...
Routing with a clue (RC) is one of the most interesting techniques invented for improving the performance of routing techniques in IP networks by distributing the IP lookup process to all nodes along the path. The technique utilizes a small unit called "clue" to carry the IP lookup information onto the next node in the path. On the other hand, multiprotocol label switching (MPLS) is claimed...
