Session Initiated Protocol (SIP) and Message-Based Load Balancing (MBLB)

At the service provider level, the number of VLAN, TCP or UDP port, and IP triplet combinations is affecting the Session Initiated Protocol SIP. Between servers, where the VLAN, TCP port, and IP variations are limited, the ephemeral ports are constantly being pushed and overrun. Because of active SIP subscriber...

UDPXfer (zip)

The UDPXfer application was designed to be a small utility that will help users transfer single files to another host over UDP, supporting both active and passive connections. For most file transfers, TCP usually provides the highest speed and reliability. However, on high packetloss lines (20%+), the lost TCP segments...

High Performance User Level Sockets Over Gigabit Ethernet

While a number of User-Level Protocols have been developed to reduce the gap between the performance capabilities of the physical network and the performance actually available, applications that have already been developed on kernel based protocols such as TCP have largely been ignored. There is a need to make these...

Achieving High Throughput in Low Multiplexed, High Bandwidth, High Delay Environments

This paper explores combining ECN bits and loss feedback to achieve a high throughput connection in a high bandwidth, low multiplexed environment. In the scheme, a TCP source reacts differently on receiving an ECN than it does on inferring a packet loss in terms of congestion window update. Coupled with...

AntiECN Marking: A Marking Scheme for High Bandwidth Delay Connections

This paper describes a simple scheme that uses feedback from underutilized high capacity links to allow a TCP connection to aggressively increase its sending rate. The feedback is in the form of a single bit in the packet header and is given per packet. The scheme uses aggregate information to...

Understanding TCP Over TCP: Effects of TCP Tunneling on End-to-End Throughput and Latency

TCP tunnel is a technology that aggregates and transfers packets sent between end hosts as a single TCP connection. By using a TCP tunnel, the fairness among aggregated flows can be improved and several protocols can be transparently transmitted through a firewall. Currently, many applications such as SSH, VTun, and...

Analysis of a Window-Based Flow Control Mechanism Based on TCP Vegas in Heterogeneous Network Environment

Another version of TCP called TCP Vegas has been proposed and studied in the literature. It can achieve better performance than the current TCP Reno. In the previous studies, steady-state behavior of a window-based flow control mechanism based on TCP Vegas has been analyzed for a simple network topology. This...
