0x0000 | 不压缩 | RFC 5795 |
0x0001 | RTP/UDP/IP | RFC 3095,RFC 4815 |
0x0002 | UDP/IP | RFC 3095,RFC 4815 |
0x0003 | ESP/IP | RFC 3095,RFC 4815 |
0x0004 | IP | RFC 3843,RFC 4815 |
0x0006 | TCP/IP | RFC 6846 |
0x0101 | RTP/UDP/IP | RFC 5225 |
0x0102 | UDP/IP | RFC 5225 |
0x0103 | ESP/IP | RFC 5225 |
0x0104 | IP | RFC 5225 |
其中,以太帧的头部可以采用第一子协议标识进行压缩,数据部的头部可以采用第二子协议标识进行压缩;或者以太帧的头部和数据部的头部可以采用同一子协议标识进行压缩。例如,该第一子协议标识可以如表1中的ID0x0001、0x0002、0x0003、0x0004或0x0006,该第二子协议标识可以如表1中的0x0101、0x0102、0x0103或0x0104。
在第一设备基于子协议标识对以太帧压缩完成之后,第一设备可以向第二设备发送该压缩后的以太帧。第二设备在收到该压缩后的以太帧之后,可以对该以太帧进行解压,并可以反馈压缩结果,该解压结果可选地可以反馈该以太帧是否解压成功,进一步地可以反馈该以太帧的那部分头部是否解压成功。即该解压结果针对的是以太帧的头部和/或数据部的头部。
可选地,如果第二设备解压的是数据部的头部,则可以反馈针对数据部的头部的解压结果;如果第二设备解压的是以太帧的头部,则可以反馈针对以太帧的头部的解压结果;如果第二设备解压的是以太帧的头部和数据部的头部,则可以针对以太帧的头部和数据部的头部整体进行反馈或者分别反馈;如果仅有以太帧的头部没有解压成功,也可以反馈以太帧的头部和数据部的头部都没有解压成功;或者如果以太帧的头部和数据部的头部都没有解压成功,第二设备也可以针对各部分进行单独反馈,例如,以太帧的头部没有解压成功,则可以反馈以太帧的头部没有解压成功,数据部的头部没有解压成功,则可以反馈数据部的头部没有解压成功。
可选地,反馈结果可以承载于反馈包,该反馈包针对的该以太帧中包括的各种头部 的至少部分头部的解压缩反馈。例如,以太帧的头部和/或数据部的头部。
在第一设备接收到该反馈包的情况下,如果反馈包指示至少部分头部没有解压缩成功,则第一设备可以重传该至少部分头部,或者也可以重传该以太帧;或者,
在第一设备接收到该反馈包的情况下,如果反馈包指示至少部分头部没有解压缩成功,则第一设备确认是否进行压缩状态机迁移,如需迁移采用更可靠的压缩状态机进行头压缩。相应的解压缩端按照对应的解压缩状态机进行解压缩。
可选地,该第一设备可以从该反馈包中,获取所述第一信息。例如,该第一信息可以是反馈包中包括的子协议信息,如子协议ID,该第一信息也可以是反馈包中的标志信息,或者可以是该反馈包的标识,还可以是该第一信息也可以是反馈包的格式。
也就是说,该第一设备可以根据反馈包,区分该反馈包中的头解压缩状态对应的对以太帧的头部还是数据部的头部,进而第一设备就可以进行相应的重传或压缩状态机迁移。
在一种实现方式中,可以使用该反馈包中的子协议信息区分该反馈包中的头解压缩状态针对的是以太帧的头部还是数据部的头部。例如,以太帧的头部和数据部的头部的子协议信息不同,可以在反馈包中携带进行解压的子协议信息,子协议信息1对应的是以太帧的头部,子协议信息2对应的是数据部的头部。
在另一种实现方式中,可以使用反馈包中的标志信息区分该反馈包中的头解压缩状态对应的是以太帧的头部还是数据部的头部。可选地,该标志信息可以是反馈包的头部的预留比特,或者是反馈包中的PDU类型域中的指示比特,或者是新增的域信息。
例如,该反馈包的格式可以如图3所示,该反馈包的头部的原有预留比特可以用于进行指示该反馈包中的头解压缩状态对应的是以太帧的头部还是数据部的头部。例如,携带一定值可以是以太帧的头部,没有携带一定值则是数据部的头部,或者携带一定值是数据部的头部,没有携带一定值的是以太帧的头部。或者,携带一个值是以太帧的头部,携带另一值是数据部的头部。
