Can You Allow Your Heart to Stop Beating?

3. Increasing the Network Bandwidth
The Problem:
Hunger for bandwidth
The average number of users within a LAN in rapidly increasing
The network becomes the heart of the business - not only PCs or workstation are connected

4. Increasing the Network Bandwidth
The Solution:
Connecting the users using Fast Ethernet links
Deployment of Gigabit Ethernet in the network backbone
Gigabit Ethernet removes backbone bottlenecks

5. Increasing the Network Bandwidth
The Optical Access Advantage:
Pioneer in Gigabit Ethernet
Easy migration from FE to GE
In-house fiber optic technology that enables achieving 60km distance over singlemode fiber
Standard base Copper Gigabit Ethernet support

6. Aggregating Multiple Links
The Problem:
Breaking the GE bandwidth link limitation
The need to increase the bandwidth with a cost effective solution
Connecting powerful servers to the network with a fault tolerance connection

7. Aggregating Multiple Links
The Solution:
Aggregating multiple ports into a single group
Effectively connecting between the switch and the server
Achieve higher bandwidth either on FE links or GE links

8. Aggregating Multiple Links
The Optical Access Advantage:
Providing fault tolerance
Combining up to 8 GE or FE links per trunk
Multiple aggregation links in a single switch
Copper or Fiber aggregation
Standard based solution

9. Reducing The Duplicated Traffic Over The LAN
The Problem:
Eliminating broadcast storms within the network
Enabling multiple applications that consume high bandwidth (such as Video applications) to run simultaneously without losing the network performance
Translating IP Multicast into Ethernet broadcast

10. Reducing The Duplicated Traffic Over The LAN
The Solution:
Implementing IGMP Snooping, enabling IP Multicast group support at Layer 2
Increasing the network performance by using Multicast instead of broadcast

11. Reducing The Duplicated Traffic Over The LAN
The Optical Access Advantage:
Eliminating the need to use multiple point-to-point sessions
Implementing the IGMP feature without loosing performance
Standard solution based on IGMP Version 2 (RFC 2236)

12. Achieving Security The Problem:
New commercial applications and service providers look for an access control method that will enable them to control the usage of the network
First level of security at the infrastructure level
Keeping unauthorized users out of the network

13. Achieving Security The Solution:
Deployment of MAC based intrusion control
Easy tool for setting and maintaining the access of the authorized users

14. Achieving Security The Optical Access Advantage:
Enabling authorization of multiple users per port or per switch
Supporting large scale of authorized users
Remote management for controlling the intrusion control

15. Centralized, Remote Configuration Control
The Problem:
Network becomes the Critical Resource
Downtime for upgrade is a crucial issue
There are some configuration activities which the SNMP agent cannot support
Starting mid-size network the maintenance of the network equipment is problematic
Upgrading the software can be a complicated task

16. Centralized, Remote Configuration Control
The Solution:
Including an additional management agent (BootP Client) for non SNMP activities

17. Centralized, Remote Configuration Control
The Optical Access Advantage:
Installing a BootP Client within any one of the OptiSwitch™ products
Enabling to set the switch IP address, change the default network gateway and upgrade the switches SW
Simultaneously upgrading all the NE.

18. InterSwitch Virtual LAN
The Problem:
Providing LAN services to several organizations over a single physical infrastructure
Keeping the separation between the different organizations
Providing secure domain access to different departments within the organization
Controlling the Broadcast domain

19. InterSwitch Virtual LAN
The Solution:
Using VLAN Tagging technology
Providing different network segments
Controlling broadcast and multicast traffic

20. InterSwitch Virtual LAN
The Optical Access Advantage:
Up to 2000 VLAN groups
Scalable solutions from Ethernet up to GE
Comprehensive tool for defining and managing the VLAN Tagging Network
Standard solution based on IEEE802.1q

21. Providing Class of Service
The Problem:
Some applications require a minimum transmission rate over the network (such a voice)
Allowing differentiated between network services and media-rich applications
Providing efficient bandwidth allocation

22. Providing Class of Service
Our Solution:
Implementing Class of Service at Layer 2
Enabling traffic prioritization
Total end-to-end solution

23. Providing Class of Service
The Optical Access Advantage:
Traffic prioritization based on port or VLan at wire-speed
Priority can be achieved by predefined functions
Standard solution based on IEEE802.1p

24. Can You Allow Your Heart to Stop Beating?
The Problem:
The network is the heart of the business, it must be operated with no failure at all times
Upgrading and maintaining the network should be achievable without shutting down the network

25. Can You Allow Your Heart to Stop Beating?
The Solution:
Redundancy at all levels

26. Can You Allow Your Heart to Stop Beating?
The Optical Access Advantage:
Removable Redundant Power Supply
Fault Tolerance links (Based on link aggregation)
Redundant Links (Redundant Gigabit Ethernet Module)
Redundant Fans
