Multi-Level Header Compression

Packet Header Compression: Split Mount & Full Outdoor• Main features:• It supports and automatically recognizes a large number of protocols:

Ethernet (802.1D – 802.1Q – 802.1ad – 802.1ah) + non-standard S-TAG ethertypes 0x9100, 0x9200 and user definedMPLS + “MPLS-like” PW with or without Control Word (RFC4385)IPv4/IPv6UDPRTPGTP-U (for IP tunneling with eNodeB)

• It supports header with size up to 64 bytes (single-level HC) or up to 128 bytes (dual-level HC)• It compresses simultaneously a large number of flows

up to a theoretical maximum of 4096• Compression CRCs and Feedback messages in order to ensure a correct

compression/decompression process

• NO additional latency (<5us)• No impact on link budget
