TCP-ABC: From Multiple TCP Connections to Atomic Broadcasting
نویسندگان
چکیده
In this paper, we propose a novel scheme, named as TCP-ABC, which replicates the server side TCP connections among multiple server nodes of a cluster. By guaranteeing atomic request delivery, and consensus on responses, this scheme provides the legacy server applications running on the server nodes with multiple active backups in a transparent fashion. By failing the connections over healthy units, the scheme enhances the service and data availability of the cluster. By conducting experiments on the prototype system of a cluster up to four nodes, we find TCP-ABC results in small performance lost while greatly enhances the service and data availability.

Evaluating Multipath TCP Resilience against Link Failures
Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...
متن کاملAn Intelligent Coherent Approach to Cooperation between TCP and ATM Congestion Control Algorithms - Modeling and Simulation Analysis
The combination of transmission control protocol (TCP) and asynchronous transfer mode (ATM) to deliver transport services may incur significant performance penalties due to the interaction of congestion control algorithms of TCP and ATM. In this paper, the authors examine two control categories (explicit window adaptation [EWA] and ACK bucket control [ABC]) and their representative schemes. In ...
متن کاملEffects of time, temperature and precursor on solid state synthesis of α-TCP
The effects of solid state synthesis process parameters (time and temperature) and primary calcium precursor on the amount of produced α-tricalcium phosphate (Ca3(PO4)2 or α -TCP) have been investigated. α-TCP was synthesized by firing of stoichiometric amount of calcium carbonate and monetite in first group and calcium carbonate and brushite in the second group, once at 1350°C for 3,6,8,16 h d...
متن کاملAn Initial Prototype of Multi-Connection TCP Transport
Within the G-Lab NETCOMP project [1], we have developed Multi-Connection TCP (MCTCP) transport as a new multipath transport solution. MCTCP aggregates multiple Transmission Control Protocol (TCP) connections between potentially different addresses into a single session that can be accessed by an application like a single TCP connection. MCTCP encodes control information, as far as possible, in ...
متن کاملSteady State Analysis of TCP Connections with Different Propagation Delays
In the current Internet, most of the traffic is transmitted by TCP (Transmission Control Protocol). In [1], we have proposed a modeling approach for the entire network, including TCP congestion control mechansims operating at source hosts and the network seen by TCP connections, as a single feedback system. However, in [1], our analytic model is limited to a simple network, where TCP connection...
