[srslte-users] Running Two instances of srsepc

[Tejas Harekrishna Sadarahalli]

Hey all,

We are trying to implement a network slicing algorithm, where in the UE and
eNB have two slices each and each slice shares the same RAN but each slices
needs its own CN. We are running the eNB and UE on PC1 and we want to run
two instances of srsepc using two different configuration files on the same
PC (PC2),

We were wondering if this is possible?

We tried it out, but we were not successful as we get the following error







*---  Software Radio Systems EPC  ---Reading configuration file
epc.conf.example...HSS Initialized.Error binding SCTP socketError
initializing GTP-C*

in the first srsepc (epc.conf.example) configuration file (A)  we left the
parameters unchanged and for the second srsepc (epc.conf.example)
configuration file (B) in an another copy of the srslte we changed the:


*mme_code = from 0x1a to 0x1b *

*sgi_if_addr    = from  172.16.0.1 to 172.16.0.2sgi_if_name    = from
srs_spgw_sgi to srs_spgw_sgi2*

we left the mme_bind_addr and gtpu_bind_addr the same in both the
epc.conf.example files as we want the same eNB to connect too the two
different instances of srsepc


*mme_bind_addr = 192.168.0.3*
*gtpu_bind_addr = 192.168.0.3*

Any idea how its possible to run two instances of srsepc on the same PC?
Any thoughts or suggestion would be highly appreciated.
