• Message Oriented Middleware allows general purpose messages to be exchanged in a Client/Server system using message queues.
• Station A needs to send a message consisting of 9 packets to Station B using a sliding window (window size 3) and go-back-n error control strategy. All packets are ready and immediately available for transmission. If every 5th packet that A transmits gets lost (but no acks from B ever get lost), then what isthe number of packets that A will transmit for sending the message to B?
