Middleware is distributed software required to support interaction among clients and servers. In short, it is the software that is in the middle of the Client/Server systems and it acts as a bridge among the clients and servers. It starts with the API set on the client side that is used to request a service and it covers the transmission of the request over the network and the resulting response.
It neither consists of the software that gives the actual service - that is in the servers domain nor the user interface or the application login - that's in clients domain.
Data Routing Functions The data routing functions are functions that when executed set the path between source and destination. In dynamic interconnection networks there may be

Error Detecting Code - Parity bit: The general idea for achieving error detection and correction is to add some redundancy (i.e., some extra data) to a message, which receiver
The performance of interconnection networks is calculated on the given parameters. Bandwidth: It is a calculated of maximum transmit rate among two nodes. It is calculated i
Enumerate about the Traffic policing Traffic policing happens when a flow of data is regulated so that cells (or frames or packets) that exceed a performance level are discarde
Suppose that frames are 1250 bytes long including 25 bytes of overhead. Also assume that ACK frames are 25 bytes long. Calculate the efficiency of stop-and-wait ARQ (a) Transmits a
Carrier Sense Multiple Access/Collision Avoidance a) Necessary since wireless LANs cannot implement CSMA/CD b) Collision detection requires increased bandwidth requirements
State about the international standardization There are many examples, certainly. Some systems for which there is international standardization include compressed disc players
Sending a message to a group multicast address is known as multicasting, and its routing algorithm is known as multicast routing.
