Wireless Serial Device Server with Ethernet over VDSL Interface

ROS Features  
Serial IP Encapsulation  
Many 'legacy' devices (RTU, PLC, IED, etc.) only support  
serial communications via RS232, RS422 or RS485. ROS™  
that are 'pruned' to prevent loops. eRSTP yields worst-case  
fault recovery1 of 5ms times the 'bridge diameter' and allows  
rings of up to 80 switches. For example, a ring of ten switches  
encapsulates the serial data within a TCP connection allowing will have fault recovery times under 50ms. eRSTP implements  
these devices to be reached via an IP network. A wide range  
of baud rates, frame packetization options, and diagnostics  
allows any serial protocol to function. The RS416 has specific  
support for the following serial protocols:  
Raw Socket serial encapsulation  
Modbus TCP (client and server)  
DNP 3  
both STP and RSTP to ensure interoperability with commercial  
switches unlike other proprietary 'ring' solutions.  
Quality of Service (IEEE 802.1p)  
Some networking applications such as real-time control  
or VoIP (voice over IP) require predictable arrival times for  
Ethernet frames. Switches can introduce latency in times  
of heavy network traffic due to the internal queues that buffer  
frames and then transmit on a first come first serve basis.  
ROS™ supports 'Class of Service' in accordance with IEEE  
802.1p that allows time critical traffic to jump ahead to the  
front of the queue thus minimizing latency and reducing jitter  
to allow such demanding applications to operate correctly.  
ROS™ allows priority classification by port, tags, MAC  
address, and IP type of service (TOS).  
WIN and TIN  
Microlok  
MODBUS TCP  
The Modbus protocol is ubiquitous in the industrial control  
and automation world. ROS converts Modbus RTU  
master/slave serial data packets to Modbus TCP client/server  
packets for transmission over an IP network. This allows  
communications to Modbus RTU slaves via Ethernet and  
allows multiple masters to poll the same slave device.  
A configurable "weighted fair queuing" algorithm controls how  
frames are emptied from the queues.  
Cyber Security  
Cyber security is an urgent issue in many industries where  
advanced automation and communications networks play  
a crucial role in mission critical applications and where high  
reliability is of paramount importance. Key ROS™ features that  
address security issues at the local area network level include:  
VLAN (IEEE 802.1q)  
Virtual local area networks (VLAN) allow the segregation  
of a physical network into separate logical networks with  
independent broadcast domains. A measure of security is  
provided since hosts can only access other hosts on the  
same VLAN and traffic storms are isolated. ROS™ supports  
802.1q tagged Ethernet frames and VLAN trunks. Port  
based classification allows legacy devices to be assigned  
to the correct VLAN. GVRP support is also provided to  
simplify the configuration of the switches on the VLAN.  
Passwords - Multi-level user passwords secures switch  
against unauthorized configuration  
SSH / SSL - Extends capability of password protection to  
add encryption of passwords and data as they cross  
the network  
Enable / Disable Ports - Capability to disable ports so that  
traffic can not pass  
Link Aggregation (802.3ad)  
802.1q VLAN - Provides the ability to logically segregate  
traffic between predefined ports on switches  
MAC Based Port Security - The ability to secure ports on  
a switch so only specific Devices / MAC addresses can  
communicate via that port  
802.1x Port Based Network Access Control - The ability  
to lock down ports on a switch so that only authorized  
clients can communicate via this port  
Radius - Provides centralized password management  
SNMPv3 - encrypted authentication and access security  
The link aggregation feature provides the ability to aggregate  
several Ethernet ports into one logical link (port trunk) with  
higher bandwidth. This provides an inexpensive way to set up  
a high speed backbone to improve network bandwidth. This  
feature is also known as "port trunking", "port bundling", "port  
teaming", and "ethernet trunk".  
IGMP Snooping  
ROS uses IGMP snooping (Internet Group Management  
Protocol v1&v2) to intelligently forward or filter multicast traffic  
streams (e.g. MPEG video) to or from hosts on the network.  
This reduces the load on network trunks and prevents  
packets from being received on hosts that are not involved.  
ROS™ has a very powerful implementation of  
IGMP snooping that:  
The ROS™ cyber security features are included to help  
address the various industry specific security standards such  
as NERC CIP, ISA S99, AGA 12, IEC 62443, ISO 17799:2005  
and PCSRF SPP-ICS.  
Enhanced Rapid Spanning Tree Protocol (eRSTP™)  
RuggedCom eRSTP allows the creation of fault-tolerant ring  
and mesh Ethernet networks that incorporate redundant links  
1 eRSTP fault recovery times may be approximated as follows:  
For 100 Mbps, fault recovery performance is <5ms/hop  
For 1,000 Mbps, fault recovery performance is <5ms/hop + 20ms

ROS Features  
Can be enabled on a per VLAN basis.  
Port Configuration and Status  
Detects and filters all multicast streams regardless of  
ROS™ allows individual ports to be 'hard' configured  
for speed, duplex, auto-negotiation, flow control and more.  
This allows proper connection with devices that do not  
negotiate or have unusual settings. Detailed status of ports  
with alarm and SNMP trap on link problems aid greatly in  
system troubleshooting.  
whether subscribers exist.  
Supports "router-less" operation by supporting an  
"active" mode.  
Restores traffic streams immediately after an RSTP  
topology change.  
SNMP (Simple Network Management Protocol)  
Port Statistics and RMON (Remote Monitoring)  
ROS™ provides continuously updating statistics per port  
that provide both ingress and egress packet and byte  
counters as well as detailed error figures. Also provided  
is full support for the RMON statistics, history, alarms, and  
event groups. RMON allows for very sophisticated data  
collection, analysis and detection of traffic patterns.  
SNMP provides a standardized method for network  
management stations the ability to interrogate devices from  
different vendors. SNMP versions supported by ROS™ are  
v1, v2c, and v3. SNMPv3 in particular provides security  
features (such as authentication, privacy, and access control)  
not present in earlier SNMP versions. ROS™ also supports  
numerous standard MIBs (Management Information Base)  
allowing for easy integration with any network management  
system (NMS). A feature of SNMP supported by ROS™ is  
the ability to generate "traps" upon system events. A NMS  
can record traps from multiple devices providing a powerful  
network troubleshooting tool. RuggedVueTM is RuggedCom's  
NMS that provides graphical visualization of the network  
and is fully integrated with all RuggedCom products.  
Event Logging and Alarms  
ROS™ records all significant events to a non-volatile  
system log allowing forensic troubleshooting. Events  
include link failure and recovery, unauthorized access,  
broadcast storm detection, and self-test diagnostics  
among others. Alarms provide a snapshot of recent  
events that have yet to be acknowledged by the network  
administrator. An external hardware relay is de-energized  
during the presence of critical alarms allowing an  
external controller to react if desired.  
SCADA and Industrial Automation  
ROS™ contains features that optimize network performance  
and simplify switch management based on the unique  
requirements found in SCADA and industrial automation  
applications. Features such as Modbus TCP management for  
retrieval of switch data using the ubiquitous Modbus protocol  
and DHCP Option 82, a Rockwell Automation ODVA  
requirement for IP address assignment based on the location  
of the end device, provide capabilities not found in typical  
"commercial" or "office grade" Ethernet switches.  
HTML Web Browser and Telnet User Interfaces  
ROS™ provides a simple, intuitive user interface for  
configuration and monitoring via a standard graphical  
web browser or via Telnet. All system parameters include  
detailed on-line help to make setup a breeze. ROS™ ,  
presents a common look and feel and standardized  
configuration process allowing easy migration to other  
RuggedCom managed products.  
Port Based Network Access Control (802.1x)  
ROS™ supports the IEEE 802.1x standard that defines  
a mechanism for port-based network access control which  
provides a means of authenticating and authorizing  
devices attached to LAN ports.  
Configuration via ASCII Text File  
All configuration parameters are stored in an ASCII  
formatted text file that can easily be transferred via TFTP  
or Xmodem. The configuration file can be saved for  
backup purposes and easily manipulated by a text editor.  
The same text file can be downloaded to the switch at  
a later date in order to re-configure or restore a previous  
configuration.  
Port Rate Limiting  
ROS™ supports configurable rate limiting per port to limit  
unicast and multicast traffic. This can be essential to  
managing precious network bandwidth for service providers.  
It also provides edge security for denial of service  
(DOS) attacks.  
Command Line Interface (CLI)  
A command line interface can be used in conjunction  
with remote shell to automate data retrieval, configuration  
updates, and firmware upgrades. A powerful SQL-like  
capability allows expert users the ability to selectively  
retrieve or manipulate any parameters the device  
has to offer.  
Broadcast Storm Filtering  
Broadcast storms wreak havoc on a network and can cause  
attached devices to malfunction. This could be disastrous on  
a network with mission critical equipment. ROS™ limits this  
by filtering broadcast frames with a user-defined threshold.  
Port Mirroring  
ROS™ can be configured to duplicate all traffic on one port  
to a designated mirror port. When combined with a  
network analyzer, this can be a powerful troubleshooting tool.
