Gigabit Ethernet BFS
SR 5.0 now supports direct delivery of inband broadcast file system (BFS) data to the
BFS QAM via Gigabit Ethernet. Currently, inband BFS data is delivered to the QAM
via a BIG or an ASI card on the DNCS host. Both methods require expensive
additional hardware and software. The Gigabit Ethernet BFS feature eliminates the
need for an ASI or ATM interface, though ASI is still supported in SR 5.0.

Each BFS session is a single-program transport stream (SPTS) with its own program
number and a distinct destination IP address. The uniqueness of the program
number and IP address is maintained per site. Program association table (PAT) and
program map table (PMT) data is sent for each session individually to the session's
destination IP address.
