Protocols for Asymmetric Communication Channels

Micah Adler, Bruce M. Maggs
2001 Journal of computer and system sciences (Print)  
In this paper we examine the problem of sending an n-bit data item from a client to a server across an asymmetric communication channel.  ...  The expected number of rounds of communication between the server and client in the simplest of our protocols is O (H(D) ).  ...  Asymmetric communication scenarios also arise in situations where the bandwidth provided by the underlying communication channel is not asymmetric.  ...

Bit transmission error correction scheme for FlexRay based automotive communication systems

Inhyuk Choi, Taewoo Han, Sungho Kang
2013 2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE)  
In this reason, a faster and more efficient communication protocol for high-performance is required to transmit and process a lot of information among the devices.  ...  The FlexRay supports two independent transmission channels that are configured as the fault tolerable communication and each channel has a maximum transfer rate of 10Mbps.  ...  For this reason each channel should have an individual tolerance mechanism for the transmission error.  ...

Interactive Consistency on a Time-Triggered Real-Time Control Network

Colin Ryan, Donal Heffernan, Gabriel Leen
2006 IEEE Transactions on Industrial Informatics  
Interactive consistency on a communication system can be defined as a means to ensure that all non-faulty nodes on the communication system receive a consistent value for any message communicated.  ...  This paper describes the adoption of an explicit interactive consistency algorithm on a time-triggered broadcast communication system, using a shared communication medium.  ...  The unified protocol operates on the assumption that the source nodes, for at least one communication stage, are free from asymmetric faults.  ...
