BOSTON, USA: It will likely take more than a quick reorganization for Cisco Systems Inc Chief Executive John Chambers to turn around the troubled technology bellwether.Chambers, a Silicon Valley icon who has run the company for 16 years, put his job on the line last month when he told investors that Cisco had lost its way in recent years as it spent heavily to expand into dozens of new markets. Since the rare admission, he has trimmed the company’s bloated management structure, offered early retirement to some employees, killed the Flip camcorder and laid off 550 workers. More changes are in the works. Wall Street analysts will grill him about what’s next on Wednesday when Cisco holds its quarterly earnings conference call. Expectations are low as the company has disappointed for the past three quarters. Its shares have lost 20 percent of their value since the company’s last quarterly report, on Feb 9. Analysts want to hear how Chambers intends to revive his bread-and-butter business of selling the plumbing of the Internet and corporate networks. They will zero in on its switching business, where sales dropped 7 percent in its most-recent quarter. “They’ve been under margin pressure and share pressure and it’s only going to get worse,” said Joe Skorupa, an analyst with Gartner. The research firm recently issued a report advising clients who had long used Cisco switches to diversify their networks to include products from other manufacturers including Hewlett-Packard Co and Juniper Networks. MULTIPLE RIVAL PROVIDERS Conventional wisdom has been it was cheaper to build a network with equipment from a single provider — Cisco — because those switches were designed to work together. But Gartner told its clients they were better off using multiple vendors — summing up the trend of past years in the $21 billion-a-year market for switching equipment, where Cisco commands a 67 percent market share. Rivals such as Juniper and HP have caught up with Cisco in terms of features, sell their products for less and provide software for operating their switches that is easier to manage than Cisco’s offering, Gartner told its clients. “Folks are nipping at their heels from a technology perspective,” said Gerard Gibert, CEO of Mississippi-based Venture Technologies, a firm that sells Cisco equipment. One area where Cisco has fallen behind is in manageability. The company sells several lines of switches, which run on different operating systems. HP and Juniper, by contrast, offer their customers one piece of software for managing all their switches. That means customers need to spend less training IT staff. Cisco has begun to address the issue through a new product dubbed Cisco Prime, which it recently introduced. “I do think there are some improvements they could make in some of their products,” said Rolf Versluis, CEO of Adcap Network Systems, another Cisco reseller.
What are the advantages of broadband VPN? There are several advantages associated with broadband VPN. These include: Bonding DSL – one of the main advantages of using a broadband VPN through Managed Communications is the ability to bond ADSL at multiple office locations to deliver a point to point connection. This broadband VPN solution offers resilience as well as increased broadband capacity for downloading at both sites. Reduced cost of internet breakout – another advantage of a broadband VPN is that it cuts the cost of internet breakout. Typically, a point to point leased line requires at least one additional internet connection. If the network contains many sites, internet breakout can become very expensive. If traffic is backhauled over leased lines to save costs on internet access, you need to route that traffic through the point to point link. This reduces the available bandwidth for other applications. With a broadband VPN, you can manage internet breakout cost effectively on a site by site basis without reducing available bandwidth for applications. Get an excellent service level agreement (SLA) – with an ADSL VPN from Managed Communications, you get a private network and negate the need for leased line internet breakout. But importantly you also get a 99.9% SLA so you can be totally confident about the level you will receive. Get expert advice and keep track of the latest technological breakthroughs – our engineers are experts in Cisco VPN, Checkpoint VPN and Netscreen VPN hardware. And with their years of knowledge and experience in the field, you know that you will be getting the best possible outcome for your business. Nobody knows more about VPN networks than Managed Communications. Can I use SDSL in the VPN? Yes. SDSL is commonly used in the VPN solutions we provide, making Managed Communications a great fit for companies that upload large amounts of data on a regular basis. If your business operates in the creative sector, regularly updates websites or stores a lot of data in the cloud, an SDSL VPN network could save you time and money. However, the VPN networks at Managed Communications are not merely limited to SDSL. Ethernet, traditional leased lines, ADSL and SHDSL can also be used in the VPNs that we provide to individuals and businesses. Can I use a broadband VPN as an alternative to a leased line? Yes. A broadband VPN from Managed Communications is often used to replace leased lines. You get up to 13 static IPs, a 99.9% SLA and a secure private network. This means that you can enjoy a solution that combines the best of both worlds – a high level of performance approaching that of a leased line with surprisingly low operating costs. Is your VPN service secure? Yes. You will be able to benefit from a totally private UK wide VPN infrastructure when you access the Managed Communications VPN service. This private network architecture is a vital component of our secure and reliable VPN solutions. The carrier grade 3DES technical architecture combined with layered IP technology allows you to obtain very secure inter-site connectivity solutions using either SSL VPN orIPsecVPN.

Find out for yourself what they already know – that a VPN network is a major advantage for any organisation. Is it true that I can connect lots of sites into the VPN network? Yes. You can connect as many sites into the private VPN as you require. There is no restriction on either the number of sites that can be connected or the type of connectivity that can be deployed at each individual site. You can also choose between broadband or MPLS VPN technology. Can I connect my remote staff into my office systems over a VPN? Yes. You can securely connect sales staff, directors and other remote workers into your head office systems. A popular and cost effective option is to bond several DSL circuits at head office to enable the upload performance required to support multiple remote staff at locations around the UK. Customers have an impressive choice of Cisco VPN, Checkpoint VPN and Netscreen VPN hardware. Can I run VoIP over a managed VPN? Yes. You can choose to run voice over MPLS VPN or over a broadband VPN. 1:1 contention levels, 99.9% SLA, up/downstream QOS and advanced traffic routing mean that Managed Communications VPN services are an ideal choice for running VOIP

Cisco AP 541N is a robust wireless access point with business-class features including Clustering technology for a single point of administration for multiple access points. With clustering technology, you can configure and manage all access points as a single wireless network, rather than as a collection of individual devices without the need for a wireless controller. Building a large wireless network in businesses or campuses with multiple buildings frequently requires multiple wireless access points to deploy. Wireless access point devices have limitation in the network coverage particularly when the obstacles exist. The number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your environments. Deployment a single access point device to cover a large area with multiple buildings such as large office buildings, multiple storey buildings, may not be adequate in providing good signal strength to the clients. Therefore deployment of multiple access point devices would be a solution to cover dead spots. Setting up and configuring multiple devices are generally performed one by one that may lead to miss-configuration and administration overhead. Cisco introduces AP 541N Wireless Access Point with clustering technology. Clustering technology allows you centralize a single point of administration for multiple access point deployments. What this Product Does Cisco AP 541N Wireless Access Point is powered by the latest wireless technology 802.11n with selectable dual-band frequency either 2.4 GHz or 5 GHz and combined with smart antenna MIMO (multiple-input multiple output) technology to provide much greater resiliency and data throughput. Cisco AP 541N Wireless Access Point supports clustering technology for a single point of administration for multiple access points deployment. Clustering technology makes it easy to set up, configure, and run your network. Clustering is the ability of a wireless access point to form a dynamic, configuration-aware group (called a cluster) with other similarly designed access points in the same network and subnet. All access points in the cluster self-organize, cloning configuration settings from one access point to another and balancing wireless channels to minimize radio interference. The cluster also provides a single point of administration, allowing you to configure and manage all access points as a single wireless network, rather than as a collection of individual devices without the need for a wireless controller. With clustering, you can share the following information within the cluster • Wireless network identifier (SSID), which is the your unique network name • Security features, such as encryption settings (WPA, WPA2, or WEP), access lists, and MAC address filters (either allowed or denied) • User names and passwords • Quality of service (QoS) settings • Radio settings • Wireless interface settings • Guest welcome screen Cisco AP 541N supports a secure guest access which is easy to setup using easy to follow graphical user interface (GUI). With secure guest access, you can create a security boundary separated from your private networks to allow your business partners and other visitors to access the internet when they visit your business location without granting them any visibility into your business network and without impeding the performance of your business applications. You can also provide a welcome screen to greet visitors using your guest network. Cisco AP 541N access point supports strong security features including advanced Wi-Fi Protected Access (WPA2) encryption, rogue access point detection, access control lists, and MAC address filtering. Cisco AP 541N access point can be operated either in a standalone wireless access point or as part of a larger business network. You can easily add the wireless access points to grow with your business as your needs change, while minimizing operational costs. Deployment can be flexible either using AC power or Power over Ethernet (PoE) to simplify installation in locations where no power outlets are available such as in ceilings to support virtually any deployment. Cisco AP 541N wireless access point is a robust system which can be deployed in stand alone or part of your large business with business class security features to better protect your employees, your guests, and your business.
