Optical-Based Switching Solutions The OptiSwitchTM Layer 2 Solution Israel, August 2000 Eyal Nouri, Product Manager

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?

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

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

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

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

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

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

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

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

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)

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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
