But they all have the Base Header, and that header has: 3 bits of packet type; 1 bit of payload configuration; 1 bit of: header mode, if the payload configuration bit is 0; segmentation/concatenation, if the payload configuration bit is 1;

ATSC 3.0 includes a new link layer protocol known as ALP (ATSC Link-layer protocol). So the first two octets of the packet data contain the Base Header? That appears to be a 16-bit header; in a capture, in what order are the bytes of the Base Header, and in what order are the bit fields? The

[tcpdump-workers] Linktype allocation for ATSC link layer protocol

2019-10-14 Thread Nick Kelsey
ATSC 3.0 includes a new link layer protocol known as ALP (ATSC Link-layer protocol). A linktype allocation would enable packet capture and diagnostics of the ATSC 3.0 link layer. Proposed linktype allocation: LINKTYPE_ name = LINKTYPE_ATSC_ALP LINKTYPE_ value = 289 Corresponding DLT_ name = D
