有关SCTP（Stream Control Transmission Protocol，流控制传输协议）描述错误的是（）。A、SCTP偶联具有多地址性，一个SCTP偶联的两个SCTP端点都可以配置多个IP地址，一个偶联的两个端点之间具有多条通路B、面向无连接的可靠传输协议C、基于分组的的靠传输协议D、一个SCTP传送地址由一个IP地址加一个SCTP端口号决定，SCTP端口号就是SCTP用来识别同一地址上的用户，和TCP端口号是一个概念

SCTP偶联是eNODEB与MME\eNODEB通信的基础，目前SCTP参数最多只能配置『____』条偶联。( What is the maximum coupling of SCTP Currently in eNODEB『____』?)

在J2EE中，下面的代码中出现编译错误的是()。

A.Filef=newFile("/","autoexec.bat");

B.DataInput Streamdin=new Data Input Stream(new File Input Stream("autoexec.bat"));

C.Input Stream Readerin=new Input Stream Reader(System.in);

D.Output Stream Writer out=new Output Stream Writer(System.in);

●TCP(Transmission Control Protocol)was specifically designed to provide a reliable end-to-end byte stream over a(n) (70) ．

(70) A．IP address

B．reliable network

C．socket

D．unreliable internetwork

A.SCTP的连接可以是多地址连接，而TCP则一般是单地址连接的。

B.TCP是基于比特流，SCTP则是基于用户消息流。

C.一个SCTP则只能支持一个流，一个TCP连接同时可以支持多个流（stream）。

D.SCTP增加了防止攻击的措施（Tag，Cookie，MAC…）。

A. Transport layer divides a data stream into segments & adds reliability & flow control information

B. Data link layer adds physical source & destination address & an FCS to the segment

C. Packets are created when the network layer encapsulate a frame with source & destination host address& protocol related control information

D. Packets are created when the network layers adds layers 3 address & control information to a segment

E. The presentation layer translated bits into bits into voltages for transmission across the physical link
