2. Agenda • Increasing the Network Bandwidth • Aggregating Multiple Links • Reducing The Duplicated Traffic Over The LAN • Achieving Security • Centralized, Remote Configuration Control • InterSwitch Virtual LAN • Providing Class of Service • 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 applicationsand 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
