MINT is Simple

To establish wireless connection

between two devices:

Setting radio parameters:

rf rf4.0 freq 5200 bitr 36000 sid 10101010 pwr 63

Starting MINT:

mint rf4.0 start

Following these commands devices will automatically establish a connectionand choose optimal parameters for transmission.

Establishing a connection takes less than 1 secondVery important forMobile deployments


9/22

Monitoring MINT network

To view MINT-network nodes map: mint map

In 3 upper rows: interface name (rf4.0) on which mint protocol is running, itsname, MAC-address, nodes id (32456), type (mesh) and key interfaceparameters.

Then it is written that our device (MINT-node) has 1 neighbor-node.

Neighbor has its own id and MAC-address.


10/22

Cost in MINT network

Cost parameter plays a great role if wehave more than 2 nodes in MINT network.

What will be the best path from one node to the other (for example, from 10 to 40)?

Each packet in the network may have its own unique path according to currentlink costs

Link cost is calculated according to its current load, bitrate and other qualityparameters. Link cost is a main parameter for optimal path finding algorithm tofind a path between two network nodes

Main criteria for optimal path selection is time (minimal packet delivery time)

MINT is monitoring network constantly.

MINT can forecast and use reserved link in advanced.


11/22

Polling mechanism

Polling - is a non-collision adaptive mechanism that solves a so called

hidden node problem when clients ofone Base Station cannot hear eachother thus starting transmittingsimultaneously and causing collisionsand retries.

Configuration example:

mint rf4.0 poll start

Notes:

Polling mode can be enabled only on the unit (or interface) with

a type master (MINT).

On master node a marker access (polling) can be enabled.Only one master in a network segment can have this optionenabled by means of which forming a star-topology segment(point-to-multipoint). With this, all other nodes break theirconnections with their respective neighbors.


12/22

Flexible routing and switching

Full-fledge router:

- RIP/OSPF- NAT- Firewall- QoS

Advanced switch:- Full bridging mode (VLAN, STP pass through)- Different bridging groups based on numerous criterion- Spread VLAN wireless switch based on MINT transport network

(Virtual Ethernet Switch)

Hybrid mode: routing and switching modes in one unit.

Incoming traffic firstly is processed by switch. Then (if not accepted byswitch) is passed to the router. This allows to build combined schemes

when one part of the traffic is switched whereas anther part is routed.

Simple router configuration:

rip start#Starts automatic routing

Simple switch configuration:

sw group 1 add eth0 rf4.0sw group1 startsw start#Starts switching with group 1


13/22

Classifier

Switch configuration is based on setting switch groups. Each group has its ownidentifier (ID).

Each switch group includes 2 or moreinterfaces (ethX, rfX, tunX).

To direct a packet in specific groupFlexible filters system is used.

Filter system analyses any possibleInformation containing in a packet:

- Vlan tag- Protocol type- Addresses (MAC and IP)- Ports- Specific options

MINT - Virtual Ethernet Switch


14/22

MINT - Virtual Ethernet Switch

Each device can have several switch groups. Different groups can be basedon the same interfaces.

Switch groups set on different devicesbut having one identifier (ID) formswitch zones.

MINT-network segment can beconsidered as Virtual EthernetSwitch where border Neighborsplay a role of external ports.

Switch has flexible packet management:- Changing VLAN IDs- Transparent packet forwarding (802.1q, broadcast, multicast)- Broadcast traffic optimization via Mesh network

- Optimal packet path among alternative ones


15/22

Join & PrfJoin functionality is used for including two different radio interfaces of one device ina single MINT network:having different radio parameters (frequency,

modulation, standards) they have no otheropportunity to be connected to each other.

Join allows two radio interfaces of the samedevice to establish a connection between eachother as if they are two different nodes in thesame network.

Moreover, Prf (Pseudo Radio interface)

allows to join also Ethernet interfaces of adevice in a single MINT network.

In this case MINT will consider Ethernet interface asa radio interface allowing configuration of a real

MINT node on it (with all the MINT capabilities).

prf0 parent eth0mint join rf4.0 rf4.1 ifconfig prf0 up

mint prf0 start

mint join rf4.0 prf0

RoamingFor mobile nodes moving betweendifferent network segments MINT support

frequency roaming and IP roaming.

Any node in a network can be appointedas Roaming Leader. It will determinefrequency parameters of this segment.

Mobile nodes using Profile system aresearching the best and possibleparameters for connection.

IP roaming is provided by DHCP and

OSPF functions. DHCP client receivesconfiguration and OSPF integrates anode in a MINT network byfinding neighbor nodes.

Remote Command ManagementRemote command management allows one MINT node to perform commands onone other or all MINT nodes in the network.

Samples:mint rf4.0 rcmd -node all -cmd "co sh" replymint rf4.0 rcmd -node all -file ftp_name:[email protected]/1.txt -reply

Automatic Firmware UpdateAirUpdate system provides with an easier ways of massive firmware upgrade inthe MINT network for a big number of the nodes (same type). In order to do thatonly one unit of each type should be manually (or through the scheduler) upgraded other units will get new firmware automatically.

Samples:mint rf4.0 airupdate active normalmint rf4.0 airupdate passive slow

mint rf4.0 airupdate active force

1. The unit is sending announcements about newfirmware. The upload request will be sent in no less than7 hours after uninterrupted work ofthe announcement source.2. The unit is waiting for the source of the latest firmwareversion.

3. Immediate upgrade all the units with new firmware.

Main Security FeaturesUnits authentication.Every InfiNet Wireless unit supports three authentication modes to

ensure that only legal units can be connected to the wireless network:

Public The simplest case of authentication. It can be used for small workgroups,point-to-point connections, mass public access networks and for MINT architecturetesting purposes. Any two nodes of the network can establish a connection if their

secret keys are equal. Static Every node has a full list of nodes with which a connection can beestablished. This mode is suitable for an autonomous area of service with no needof centralized management and monitoring. In static mode each node must have alist of all permitted neighbors in a local database.

Remote Centralized authentication mode with remote server (e.g. RADIUS orrelay). In this mode any node can request the information from a remoteauthentication server.

Syntax:

mint IFNAME -authmode {public | static | remote}


22/22

Main Security FeaturesMINT Protocol Messages Encryption.All MINT protocol messages are protected with Adler32 checksum and are

encrypted with RC4 (AcrFour) algorithm. Every node has a unique access keywhich is set as a string of variable length. This password is used to calculate aspecial security key. Security key is a MD5 signature calculated over concatenationof initial password with nodes own MAC-address. Every node encrypts all sentpacket with its own key.

Over-the-air encryption.Over-the-air encryption mechanism based on AES128 algorithm is an extremelyreliable way to protect all data transmitted by the radio from hacking and sniffing

without throughput degradation.

Syntax:mint IFNAME key SECRETKEYmint rf4.0 crypt aes
