The BSD stack with sockets *was not written by BBN*.  It was written by Bill Joy at Berkeley -- using the earlier BBN 4BSD code as a reference.  Entirely new code, but originally bug-for-bug compatible (indeed, years later, when a bug was found in the BSD TCP, the BSD folks stood up and said "that's a bug from BBN”)

My memory is that they both were maintained in parallel for several years.  Also, Bill Joy's TCP stack also had the “trailers” feature where the headers were at the end of the packet.   Documented in RFC893 (https://tools.ietf.org/html/rfc893).   Probably not so good for packet switching, but better performance on some host implementations.  That faded away at some point.
