Slow Web Sites = Lost Revenue 32% of users who have trouble accessing a Web site stop using it or find an alternative. (Zona Research, 1999) $4. 35 billion in online revenue is at risk each year due to Web wait! (Zona Research, 1999) • Amazon losing one customer due to slow Web site - $20 • United Airlines lost sales / hour due to reservations system failure (9, 000 bookings/hour) $3. 5 million (Banc. Boston Robertson Stephens)

Every Second Counts • The difference between losing 10% of prospective customers and 30% is one second Source: Zona Research < 7 second response is crucial

Delivering Real Value “Had the equipment from Alteon not been in place, thousands of customers would have found the company’s ‘front door’ locked. ” - Mike Batchelor Ticketmaster

What’s a Content Switch? • Also known as web switching, URL switching, Layer 4 -7 switching • Directs HTTP requests to a specific server (or cache) using information about content attributes or location • Captures, parses and redirects traffic based on information found beyond Layer 4 – HTTP headers – HTTP cookies – Universal Resource Locators (URLs) • Allocates bandwidth based on content and policies

Intelligent Web Switching

How It Works. . . FILES. jpg. gif. html 6 2 1 5 3 4 FILES. cgi. asp. exe 1. A TCP connection request is made by client(s) 2. Switch responds on behalf of the server, completes the three-way TCP handshake 3. Client makes HTTP request for an active server page 4. Content switch parses HTTP request, opens connection to the appropriate server and switches traffic based on header and/or URL, while splicing the two connections together 5. Web server receives HTTP requests and responds with appropriate content 6. Content switch receives response, adjusts sequence numbers and forwards packets

How Content Switching is Different

Who needs Content Switching? • Any company that has a web portal • Any company concerned about performance • Any company worried about its security Firewalls • Any company with a server farm • Any company requiring high server availability • Any company that needs redundant data centers • Any company concerned about resilience and flexibility of their services

Solution: Caches Reducing Internet Traffic New York PCC PCC San Francisco London

Problem: Cache will sit on dataflow • When any device is on the dataflow it cannot represent a speed bump • Caches are only valuable for specific kind of data, on the dataflow caches will create a bottleneck

Solution: Web Cache Redirection What does this feature do? Web Cache Redirection, or WCR, sends appropriate requests to a Web cache, rather than to the server. This allows faster servicing of the request and offloads the servers, which Host B improves overall performance. Host C Host A Value Proposition • Provides faster response to Internet client requests Web Cache Redirector HTTPTo B HTTPTo A HTTPTo B Non-HTTP Forward at L 2/3 Local/ remote transparent proxy caches • Provides WAN cost savings • Reduces server processing

Problem: Is the network save from attacks § Hacking: Internet meaning is the repeat poking of an IP address until the machine behind the IP address responds. § Modifying content of web pages to your own wishes. § Denying the services of a computer system or network to the Internet. § Business warfare. § Graffiti on the Internet. § An alternate to Video games § A way for boring computer geeks to feel important.

Solution: Firewall Load Balancing What does this feature do? Firewall Load Balancing, or FWLB, balances the traffic going through firewalls to ensure that the firewall does not become overloaded or a bottleneck. It also keeps a firewall from being a single point of failure for the network. Internet Value Proposition • Eliminates single points of failure in a network • Allows multiple active firewalls to operate in parallel • Increases Internet access for internal users • Fw. LB and SLB can be performed on the same switch • Scalable solution Protected Network

Problem: Providing High Availability on multiple sites – Sometimes it is not safe to have the data center at only one physical locations – It is important to be able to attend the customer requests even when a entire facility is down – Also when a specific site is overloaded you should be able to steer traffic to other place

Solution: Global Server Load Balancing What does this feature do? Global Server Load Balancing (GSLB) intelligently load balances requests between mirrored sites, determining the fastest responding site to the user’s DNS. Value Proposition • Improved Availability • Improves Responsiveness • Distributes Load • Takes Geography into account • Easy to deploy and manage

Comparative Analysis

Questions to Ask • Do you have a Web-Portal? • Do you have a Server Farm? • Are you concerned about Security? • Do you have a Firewall? • Do you want to improve your Web Performance? • Do you want to offer Flexible Services? • Do you require High Server Availability? If the answer is yes to the questions above, you must consider the Alteon Content Switching solution

Alteon 184 versus Cisco/Arrow Point CSS 11000 Series Platform The CSS 11000 series has lower overall performance due to an ATM-based architecture that imposes 10% overhead, making wire-speed switching impossible. The Alteon 184 has 5 times the performance of the CSS 11150 and 2 times the performance of the 11800 in L 4. In L 7 the Alteon 184 has 4 times the performance of the 11150 and 20% higher than the 11800. The CSS 11000 series is less reliable than the Alteon 184 as it doesn’t support active load sharing between the switches. Poor integration and slower technology !!! CSS 11000 Series

Alteon 184 versus Foundry’s Server. Iron XL The Serverlon XL has serious performance issues as it does not allow to have L 3 routing and L 4 -7 processing on the same switch. It requires a combination of a Servelron and Biglron. In addition the Alteon 184 is 2. 5 times faster than the Server. Iron XL in L 7 throughput, and 2 times faster in L 4. The Serverlon XL is not a reliable switch. The switch Fabric is a single point of failure. If the ASIC fails, all the ports go dead and all traffic is interrupted. The Alteon 184 has local switching which prevents a single point of failure. Less reliable and slower technology !!! Foundry Server. Iron. XL

The PP 8600 and Alteon WSM vs. Cisco Catalyst 6500 w/ CSM The Catalyst 6500 w/ CSM has very poor integration and minimal investment protection. It requires numerous swap-outs, including supervisors, switch fabric, and line cards have to be downgraded to use new Content Switching Module. The PP 8600 & Alteon WSM is an integrated solution. The Catalyst 6500 w/ CSM has Poor Layer 3 -7 performance due to centralized processing and CSM incompatibilities. The Catalyst 6500 w/ CSM is 3 times slower for Layer 3: (30 Mpps vs. 8600’s 96 Mpps). Poor integration and slower technology !!! Catalyst 6500 w/ CSM

The PP 8600 and Alteon WSM vs. Foundry Server. Iron 800 The Serverlron 800 is less reliable. It does not have a redundancy option for the switch fabric making it a single point of failure. The PP 8600 & Alteon WSM have no single point of failure with a redundant switching fabric and a failover of less than 1 second. The Serverlon 800 has serious performance issues as it does not allow to have L 3 routing and L 4 -7 processing on the same switch. It requires a combination of a Servelron and Biglron. Less reliable and slower technology !!! Foundry Server. Iron 800
