Detailed Description
Store information about an IPv4 header between the different compressions of IP packets.
Defines an object that contains counters, flags and structures related to an IPv4 header and that need to be saved between the different compressions of packets. A compression context owns objects like this for the two first IPv4 headers.
Field Documentation
| size_t ipv4_header_info::df_count |
The number of times the DF field was added to the compressed header.
| uint16_t ipv4_header_info::id_delta |
The delta between the IP-ID and the current Sequence Number (SN) (overflow over 16 bits is expected when SN > IP-ID)
| struct c_wlsb* ipv4_header_info::ip_id_window |
A window to store the IP-ID.
| int ipv4_header_info::nbo |
Whether the IP-ID is considered as coded in NBO or not.
| size_t ipv4_header_info::nbo_count |
The number of times the IP-ID is specified as coded in Network Byte Order (NBO) in the compressed header.
| struct ipv4_hdr ipv4_header_info::old_ip |
The previous IP header.
| int ipv4_header_info::old_nbo |
Whether the IP-ID of the previous IP header was considered as coded in NBO or not.
| int ipv4_header_info::old_rnd |
Whether the IP-ID of the previous IP header was considered as random or not.
| int ipv4_header_info::old_sid |
Whether the IP-ID of the previous IP header was considered as static or not.
| int ipv4_header_info::rnd |
Whether the IP-ID is considered as random or not.
| size_t ipv4_header_info::rnd_count |
The number of times the IP-ID is specified as random in the compressed header.
| int ipv4_header_info::sid |
Whether the IP-ID is considered as static or not.
| size_t ipv4_header_info::sid_count |
The number of times the IP-ID is specified as static in the compressed header.
