A method is provided for implementing a firewall in a firewall architecture. The firewall architecture includes a plurality of network layers and a first firewall engine. The layers send packets and packet information to the first firewall engine, maintain and pass packet context to subsequent layers, and process the packets. The first firewall engine compares the packet information to one or more installed filters and returns an action to the layers indicating how to treat the packet.

IPSec encrypts and validates packets to protect the privacy of data and to ensure that no changes are made to packets during the delivery process.
IPSec对数据包进行加密和验证以保护数据的保密性，并确保在传输过程中不会对数据包进行任何更改。
Together, the switch and adapter can cut down on the number of packets the server must process.
交换机和适配器一起可以把服务器必须要处理的包的数量减少。
In common IDS, the process of rule matching is usually traversing all rules. If using pattern matching in this process, it will exhaust more time and discard more packets.
在一般的IDS中，规则匹配的过程采用遍历法，如果匹配过程中使用模式匹配，则在高速网络下就会丢失较多的数据包。
