سوال ۲۷ کنکور ارشد مهندسی کامپیوتر ۱۴۰۱

Read the following excerpt from PASSAGE 3 and answer the question.

There are two important types of packet networks: connectionless packet networks and connection-oriented packet networks. Connectionless packet networks operate in a way analogous to the post office. Connectionless networks offer best effort packet-delivery service. Connectionless packets are launched into the network with a large and powerful header that contains all the information necessary to deliver the packet, whatever its destination. As a by-product of their connectionless nature, it is not possible to guarantee performance or reserve network resources for any particular communication, so connectionless networks do not support real-time services reliably. ... When the network is subjected to overload, packets are buffered for later delivery. If the buffer capacity is exceeded, the packets are discarded. In connectionless networks there is no guarantee that all packets will traverse the same network path and be subject to the same delays.

In connectionless type, data is sent outward ----------.
