Welcome to dosiOS Page - Edge Computing Platform
Create your service functions, chain them with virtual switches and physical ports of equipment. Accelerate packet exchange with DPDK.
Use NETCONF protocol and YANG modelisation language for dosiOS management. Perform identification and physical port mapping on initial setup with provided toolkits.
Set the parameters of service function deployment (cpu, ram, ifs, disks) and virtual switch configuration (trunk, access, tag, stacked-vlans).
Available release is ALPHA version available for comments/issues/improvements.
Link to download
Link to download the iso image is presented below
Fixed restrictions in the YANG model. Fixed commands to interact with OVS. 1. fixed CNAHGE operation: set port interface X 2. fixed CHANGE operation: set port vm-port X 3. fixed CHANGE operation: set port vm-port X => set port interface Y 4. fixed DELETE operation: del port vm-port X 5. fixed DELETE operation: del port vm X 6. fixed DELETE operation: del port X
Decryption key (will be asked when start MEGA file download)
Repository provides iso image that should be flashed on the usb drive.
1. install qemu 2. qemu-img convert dosios2102.iso -O raw dosiOS-2102.img 3. dd if=dosiOS-2102.img of=/dev/sdX
After booting from usb drive you will be in “cloud image” of dosiOS.
Login: tmpuser Passwd: tmppwd
Confirm that your flash drive is something like /dev/sda and your hard drive is something like /dev/sdb.
Configuration should be performed in the BIOS (HDD priorities)
dosiOS will be installed on the /dev/sdb by default.
You may install dosiOS on the hard drive with the next command:
[email protected]:$ install image
Script of installation will be triggered:
select conf file "/config/config.boot" select console ttyS0 select the console speed 115200 Disk label: gpt
Configuration of dosiOS from NSO controller
We provide a Cisco NSO package located in this repo to controll dosiOS software from CISCO NSO controller via ietf-ucpe-yang modules

By default Edge Computing Platform is bootstraped with 4GB of hugetables. You may have 16GB ram, thus you want to modify the amount of hugetables to 12GB. To achieve that use the command below ( 6000 x 2 = ~ 12 GB)
config ecp general hugetables 6000
To display the available memory and hugetables type:
show ecp memory free-hugetables
To display the RAM status type:
show ecp memory free-memory
Port identification and mapping
This command helps to identify the connected NICs. Node address + kernel driver (igb)
To identify phy port of the NIC use this command (the phy port will be blinking):
ecp blink-port 0000:0a:00.0 igb // igb kernel driver for 1G NICs (check ecp list-nic-pci)
Next step to map pofixed DELETE operation: del port vm-port Xrts to addresses:
configure set ecp interfaces vfpX pci-addr 0000:0a.00.0
2 types of interfaces
The interfaces below represent physical ports of the equipment
The interfaces below represent virtual mgmnt ports connected with representation of physical ports (on the same link) They apper when representation of physical ports is configured on the switch.

Access to Service Functions
To list active Service Function type:
To access virtual serial console of Service Function type:
Add physical port to switch. When the physical port added to switch, you will find new interface dp0pX in the /root/interfaces/dataplane. This dp0pX is configured for management. Confirm that it was configured by
set ecp switches sw1 ports 1 interface vfp1 set ecp switches sw1 ports 2 vm sf1 set ecp switches sw1 ports 2 vm-port 1
Configuration types and (supported)/(not_supported) commands
Configuration may be done via the CREATE, DELETE, CHANGE operations. Some of them supported more than anothers in current version.
Most of creation commands except “cvlans” work as expected:
"cvlans" accepts only 1 cVLAN.
MOST of deletion commands work as expected with reserve that CHANGES commands were not used.
This operation is a bit touchy. Some code modification currently under revision to support mode commands with CHANGE operation.
CHANGE set ecp switches sw ports port X vm+port => success CHANGE set ecp switches sw ports port X vm port1 -> port2 => success CHANGE set ecp switches sw ports port X port-mode => success CHANGE set ecp switches sw ports port X tag => success CHANGE set ecp switches sw ports port X stacked-mode => success CHANGE set ecp switches sw ports port X n-txq => success CHANGE set ecp switches sw ports port X n-rxq => success CHANGE set ecp switches sw ports port X interface => success
dosiOS IPERF3 test
VM(vRouter) - sw1 - VM(vRouter)
Traffic generator -- eth1(1G) -- sw1 -- sf(router1) -- sw2 -- sf(router2) -- sw3 -- eth10(1G) -- Traffic generator
- Added Multiqueue configuration of the VNF and of the OVS.
- Fixed multiple VNFs spawning at the same moment issue.
- Added “commit failure/rollback” if VNF spawning isn’t successfull (not enough memory, empty image, wrong link, etc..)
