1This guide describes the list of the files of the project.

4There are two target binaries: mngr & bridge
5o The first  is  a simplest  tools  to  connect/disconnect
6  bridges and  check  their current connection.  These its
7  functions are managed from command line simple  language
8  and use the library libcli.a (see below). Beside it mngr
9  serves to transport BPDU messages between  bridges;  for
10  this purpose mngr uses the library libuid.a
11  The source code of the mngr: file mngr.c
12
13o The second is a simulation of virtual  RSTP  bridge.  It
14  accepts two types of messages: UID_CNTRL & UID_BPDU (see
15  file uid.h).  This program  is  linked with the same two
16  libraries libcli.a & libuid.a;  beside  it uses a system
17  independent librstp.a: implementation of Rapid  Spanning
18  Tree (802.1w) - see below.
19  The source code of the bridge: files bridge.c,stp_cli.c,
20  stp_to.c
21    * bridge.c - simulates the main bridge behavior
22    * stp_cli.c - consists from command line functions
23    * stp_to.c - API, that librstp.a uses for its purposes.
24  The management communication between bridge and librstp.a
25  uses structures and definitions from the header uid_stp.h
26
27o libcli.a - library for command line features. It has only
28  one file cli.c, the API is described in the header cli.h.
29
30o libuid.a - the 'transport' library: the source code you
31  may find in the file uid_sock.c and in the two headers:
32  uid.h & uid_sock.h
33
34o (so far, so good) librstp.a - it is a heart of the project
35  Actually, it implements 802.1w state machines. Files
36  stpm.c - the RSTP instance (some reflection of Port0)
37  port.c - the RSTP port instance
38  portinfo.c - Port Information State Machine, 17.21
39  rolesel.c - Port Role Selection State Machine, 17.22
40  roletrns.c - Port Role Transition State Machine, 17.23
41  sttrans.c - Port State Transition State Machine, 17.24
42  topoch.c - Topology Change State Machine, 17.25
43  migrate.c - Port Protocol Migration State Machine, 17.26
44  transmit.c - Port Transmit State Machine 17.27
45  pcost.c - Path Cost Resolution State Machine
46  edge.c - operEdge Port Resolution State Machine
47  p2p.c - operPointToPoit Resolution State Machine
48  statmch.c - generic state machine implementation
49  vector.c - Priority Vectors manipulations
50  times.c - Times manipulations
51  stp_in.c - API for calls from outside.
52  sttrans.c - API for calls from outside (dedicated for creation
53              deleting, starting & stopping the RSTP instance) less
54              relevant to the project.
