SharpPcap and Packet.Net are related. Packet parsing was originally a part of SharpPcap but was split out into Packet.Net in SharpPcap 3.0. Here is a helpful comparison created by Evan Plaice:
SharpPcap和Packet.Net是相關聯的。
SharpPcap
- is a libpcap/winpcap wrapper
- 是libpcap或者winpacp的封裝。
- implements filtering in a hardware interface level
- 實現了硬件接口級的過濾。
- PS：即爲在網絡適配器級別的過濾。
- captures packets from a network
- 從網絡中捕獲數據包。
- captures data in its raw format
- 捕獲原生格式的數據。
- PS：即爲網絡上發送的二進制流數據包。
- (capturing) the entry point is from the selected network interface
- 捕獲時，入口爲選中網絡適配器。
- (capturing) the exit point is passing a byte[] and/or statistics info on a capture
- 捕獲時，出口爲字節流或者附加捕獲信息
- PS：選擇一個網卡，獲取該網卡的數據量。
- (transmission) the entry point is receiving a byte[] for transmission
- (transmission) the exit point is, the data is sent across the NIC
Packet.Net
- is a networking packet parser
- 網絡包的轉換器
- is capable of retrieving the header/payload of any layer in the networking stack (at least below the application layer)
- transforms a raw byte[] of data into a usable structure through calculated carefully calculated offsets and lazy-loading (for efficiency)
- supports the ability to create a networking packet structure (using the same lazy-loading as parsing) that can be transformed into a raw byte[] for transmission
- (parsing) the entry point is a byte[] being passed in for processing
- (parsing) the exit point is the detailed data being outputted to the user
- (packet creation) the entry point is a networking packet structure
- (packet creation) the exit point is a raw byte[] being passed along to be transmitted
