ULE offers better performance and improved processing efficiency since it provides a shorter header with fewer fields compared to the currently used encapsulation technique MPE (Multi Protocol Encapsulation). In addition ULE obsoletes the mandatory use of a destination MAC address as in MPE thus achieving better transmission efficiency, especially for short packets in an IP-multicast enabled network which is usually the case in all kinds of DVB/MPEG-2 networks, such as DVB-S, DVB-C, DVB-T, DVB-H and DVB-RCS.

ULE and IPv6

Native IPv6 is supported by a ULE code point, instead of requiring the general purpose LLC/SNAP method of MPE. ULE can thus save 16 bytes of encapsulation header. Using ULE versus MPE in IPv6 networks the transmission performance will be the same compared to IPv4 and using MPE since the disadvantage of larger IPv6 headers is outweighed by the better performance of ULE.

ULE is fully supported by gcs products 

gcs has considerable experience in DVB gateway development and operation. Being on the forefront of European and international research and development activities due to participation in ESA funded projects as well as IETF working groups gcs has already implemented ULE in its IP/DVB encapsulator branded ODG - Open DVB Gateway. gcs has genuine knowledge of the ULE standard due to the co-operation in the standardisation work. gcs can therefore assure a fully functional implementation of ULE in the ODG.
