1 This guide describes the list of the files of the project.
2 ==========================================================
4 There are two target binaries: mngr & bridge
5 o 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
13 o 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,
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
27 o libcli.a - library for command line features. It has only
28 one file cli.c, the API is described in the header cli.h.
30 o libuid.a - the 'transport' library: the source code you
31 may find in the file uid_sock.c and in the two headers:
34 o (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.
