From 047f3872f511353e894659719a6c5346249bca40 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 1 Jul 2018 21:04:45 +0200 Subject: NS: Add support for GPRS NS IP Sub-Network-Service (SNS) The NS implementation part of the Gb implementation libosmogb so far implemented a rather classic dialect of Gb, with lots of heritage to FR (Frame Relay) transports. At least since Release 6 of the NS specification, there's an IP Sub-Network Service (SNS), which * permits for dynamic configuration of IP endpoints and their NS-VCs * abandons the concept of a NSVCI on IP transport * forbids the use of RESET/BLOCK/UNBLOCK procedures on IP transport This commit introduces BSS-side IP-SNS support to libosmogb in a minimally invasive way. It adds a corresponding SNS FSM to each NS instance, and implements the new SIZE/CONFIG/ADD/DELETE/CHANGE_WEIGHT procedures very closely aligned with the spec. In order to use the SNS flavor (rather than the classic one), a BSS implementation should use gprs_ns_nsip_connect_sns() instead of the existing gprs_ns_nsip_connect(). This implementation comes with a set of TTCN-3 tests in PCU_Tests_RAW_SNS.ttcn, see Change-ID I0fe3d4579960bab0494c294ec7ab8032feed4fb2 of osmo-ttcn3-hacks.git Closes: OS#3372 Closes: OS#3617 Change-Id: I84786c3b43a8ae34ef3b3ba84b33c90042d234ea --- src/gb/Makefile.am | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/gb/Makefile.am') diff --git a/src/gb/Makefile.am b/src/gb/Makefile.am index d074092e..3180f9c1 100644 --- a/src/gb/Makefile.am +++ b/src/gb/Makefile.am @@ -17,7 +17,7 @@ libosmogb_la_LIBADD = $(TALLOC_LIBS) \ $(top_builddir)/src/vty/libosmovty.la \ $(top_builddir)/src/gsm/libosmogsm.la -libosmogb_la_SOURCES = gprs_ns.c gprs_ns_frgre.c gprs_ns_vty.c \ +libosmogb_la_SOURCES = gprs_ns.c gprs_ns_frgre.c gprs_ns_vty.c gprs_ns_sns.c \ gprs_bssgp.c gprs_bssgp_util.c gprs_bssgp_vty.c \ gprs_bssgp_bss.c common_vty.c endif -- cgit v1.2.3
