We can provide three types of access to our service:
- By direct connection through a port.
A client program requests a connection through a port with our
network server. The network server, receives through a simple
protocol the name of the blast program to execute, the command line
arguments, and the query sequence. It starts the parallel blast
application, collects the results, and writes them back to the same
port. That required a lot of programming with sockets and unix
kernel calls. The server was implemented by the author, the client
program, by NCBI.
- By mail.
Users send a mail in a certain format, which is read
by a program. Our mail server parses the message, starts the
parallel blast application, collects and writes the results into a
mail message, and sends them back. This was implemented by the author.
On a mosaic page, the user can interactively give the query and
choose the value of the parameters. The mosaic server, which may be
anywhere, calls the network client program which makes a direct
connection through a port to the blast program. The results, are
displayed on a mosaic page. Kay Hoffmann at ISREC wrote a mosaic page to
interface with the network program.
