IP multicasting is a set of technologies that enable efficient delivery of data to many lo

cations on a network. Rather than making multiple copies of a message intended to be distributed to multiple recipients at the(71) of origin of a message, multicasting initially sends just one(72) and does not copy it to the individual recipients until it reaches the closest common point on the network, thereby(73) the bandwidth consumed. Network performance is significantly(74) because it isn't bogged down with the processing and transmission of several large data fries; each receiving computer doesn't have to(75) the transmitting server for the file.

A．point

B．bottom

C．head

D．sight

Thedefacto standard Application Program Interface （API） for TCP/IP applications is the “so
ckets” interface. Although this API was developed for __（71）__ in the early 1980s it has also been implemented on a wide variety ofnon-Unix systems。 TCP/IP __（72）__ written using the sockets API have in the past enjoyed a high degreeof portability and we would like the same __（73）__ with IPv6 applications。 But changes are requiredto the sockets API to support IPv6 and this memo describes these changes。These include a new socket address structure to carry IPv6 __（74）__，new address conversion functions，and some new socket options。These extensions aredesigned to provide access to the basic IPv6 features required by TCP and UDPapplications，including multicasting， while introducing aminimum of change into the system and providing complete __（75）__ for existing IPv4 applications。

Typically, an IP address refers to an individual host on a particular network. IP also acc
ommodates addresses that refer to a group of hosts on one or more networks. Such addresses are referred to as multicast addresses, and the act of sending a packet from a source to the members of a （1）group is referred to as multicasting. Multicasting done （2）the scope of a single LAN segment is straightforward. IEEE 802 and other LAN protocols include provision for MAC-level multicast addresses. A packet with a multicast address is transmitted on a LAN Segment. Those stations that are members of the （3）multicast group recognize the multicast address and （4）the packet. In this case, only a single copy of the packet is ever transmitted. This technique works because of the （5）nature of a LAN: A transmission from any one station is received by all other station on the LAN.

A.numerous

B.only

C.single

D.multicast@@@SXB@@@A.within

B.out of

C.beyond

B.unique

C.special

D.corresponding@@@SXB@@@A.reject

B.accept

C.discard

D.transmit@@@SXB@@@A.multicast

B.unicast

C.broadcast

D.multiple unicast
