And then, by using these security vulnerabilities, this paper gives the attack methods and explains how every type of OSPF protocol packet realize the attack.

为了提高OS PF路由协议的安全性，提出了抵抗针对这些漏洞实施的各种攻击的解决方案。

Internet Protocol (IP) provides a host-to-host packet — or datagram — delivery service.

网际协议(IP)提供“主机对主机”包(或数据报)传递服务。

Uses packet switching protocol based on frequency hop scheme with 1600 hops/s to enable high performance in noisy radio environments .

在无线电噪声环境里，利用基于每秒1600跳跳频表的分组交换协议可以提高系统性能。

And it features what is called mobile Internet protocol (IP), a packet data service that requires users to pay only for the amount of data they send and receive rather than for the amount of time spent on line.

The new protocol also offers enhanced security, by providing a cryptographic means of checking that a particular packet really does come from the machine it claims to.
