The rapid growth of real-time and high-priority traffic over IP networks makes network survivability more critical. Several MPLS-based recovery mechanisms have been proposed to ensure continuity of service following network impairments. These approaches, however, suffer from the transient effects that negatively impact the traffic that is being rerouted onto the protection paths. Packet loss an...

In an integrated fiber and wireless (FiWi) access network, multi-path routing may be applied in the wireless subnetwork to improve throughput. Due to different delays along multiple paths, packets may arrive out of order, which may cause TCP performance degradation. Although the effect of packet reordering due to multi-path routing has been well studied, remedy solutions are either to schedule ...

In Mobile IPv6, the handover process reveals numerous problems manifested by movement detection, non-optimized time sequencing of handover procedures, latency in configuring a new care of address and binding update to a home agent (HA). These problems may cause packet loss as well as packet disruption. To mitigate such effects, Fast handover for Mobile IPv6 (FMIPv6) has been developed. FMIPv6 c...

The paper deals with an influence of network jitter on effective packet loss in dejitter buffer. We analyze behavior of jitter buffers with and without packet reordering capability and quantify the additional packet loss caused by packets dropped in buffer on top of the measured network packet loss. We propose substitution of packet loss parameter Ppl in ITU-T E-Model by effective packet loss P...

Conventional wisdom states that TCP performs poorly when packets arrive out of order. Reordered packets interact poorly with TCP’s fast retransmit mechanism. For this reason, multipath routing is rarely used in the Internet, although it is supported by routers and routing protocols. Data center networks are very different from the Internet, having regular topologies, high-capacitylow-latency li...

Numerous studies have shown that packet reordering is common, especially in networks with a high degree of parallelism. Reordering of packets decreases the TCP performance of a network, mainly because it leads to overestimation of the congestion of the network. We consider wired networks with transmission that follows predominantly, but not necessarily exclusively, symmetric routing paths, and ...

If we assume that adversaries have unlimited computational capabilities, secure computation between mutually distrusting players can not be achieved using an error-free communication medium. However, secure multi-party computation becomes possible when a noisy channel is available to the parties. For instance, the Binary Symmetric Channel (BSC) has been used to implement Oblivious Transfer (OT)...
