A kind of typical form is the packet header with RTP (Real-time Transport Protocol real time transport protocol) information in CESoETH.Comprise RTP information in the packet header and be for circuit emulation service recovered clock more accurately when parsing is bundled into TDM information, comprise MAC (the Media Access Control) address of 6 bytes and the source MAC of 6 bytes in the CESoETH packet header, be used for switching network and seek the source that the destination of bag also shows bag simultaneously, Ethernet Type in the packet header is used for indicating ethernet type (here take Vlan tag type as example), the header packet information of Ethernet Type type back is the type parameter value, ECID (Emulated Circuit Identity), the CESoETH control byte, RTP information etc.A kind of package head format commonly used is as follows among the CESoETH:
A kind of CESoP package head format:
00?15?EB?98?36?04?00?15
EB?98?36?02?81?00?EF?A5
88?D8?00?02?41?02?00?00
00?00?80?60?1A?3C?04?1A
3C?00?02?03?04?00
