Cisco to Introduce Larger Cius Tablet Next Year

Cisco Systems in the first half of next year will release a tablet with a larger screen than the current Cius, the first move in the company's long-term plans to introduce tablets in multiple sizes, an executive said this week.
The new tablet will be released around the spring season in the U.S., and the screen size will be larger than the 7-inch screen on the current Cius tablet, said Chuck Fontana, director of Cius product management at Cisco.
"We're still working through the details of the exact form factor, but that work is under way," Fontana said, adding that the tablet size is being evaluated based on customer demand.
The company is looking at multiple screen sizes, but a lot of research is around tablets with 10-inch to 11-inch screens, Fontana said. buy Cisco is also looking at smaller Android devices with 3.5-inch to 5-inch screens from where users can access videoconferencing, collaboration and virtual desktop tools.
"The same Cius experience you'll be seeing on other form factors," Fontana said.
After delays and a long trial run, Cisco's Cius tablet start shipping in July and is targeted at businesses. The tablet has Google's Android 2.2 OS, which is code-named Froyo, and Intel's mobile processor, which is code-named Moorestown.
Cius is currently priced at US$725, higher than the iPad 2, which is priced starting at $499. The tablet is not available in retail stores and competes with business tablets such as recently introduced Hewlett-Packard's Slate 2, which has an 8.9-inch screen, and Dell's Latitude ST, which has a 10-inch screen.
Fontana described Cius as an "endpoint" device that can be used as a virtual desktop or as a mobile device for communication or collaboration. The device works with Cisco's TelePresence videoconferencing system, WebEx tools and other applications including Quad, a collaboration tool also available for the iPad and iPhone. Virtualization software from VMware and Citrix allows the tablet to run a virtualized Windows desktop. The tablet also provides access to Android Market and Cisco's AppHQ, which carries business applications tested and certified by the company.
Cisco is also working with Intel to upgrade the current Cius to Google's Android 4.0, also called Ice Cream Sandwich, and the new OS can be expected by fall, Fontana said. He declined comment on whether the new larger screen tablet would come with Android 4.0.
There are no current plans to put Microsoft's upcoming Windows 8 in the Cius tablet, but the company is keeping all hardware and software options open, Fontana said. The company is proceeding with Android, as wholesale Cisco applications can expand to other Android devices, iPads and iPhones.
Use of the Cius is growing in the enterprise as applications move to the cloud and businesses increasingly find ways to use tablets, Fontana said. There is a demand for larger screens, so one of Cisco's immediate focus is to upgrade its tablet lineup. The current Cius is being used in hospitals for doctors to interact and access documents, and by Cox Communications field workers for customer support.
Larger screens are useful in businesses, especially in dealing with rich media and for those who want wider screens but don't have a dock or a monitor, Fontana said. It will be possible to dock larger-screen Cius devices on desktop phones, and will provide a PC-like experience via secure access to virtual desktops hosted on servers.
"Some people don't want a device that's more mobile, they want something that's an endpoint that's both a videophone and a virtual desktop," Fontana said.
Smaller devices with 3.5-inch to 5-inch screens are also under consideration, Fontana said. These devices could resemble smartphones in size, but will be smaller cousins of the larger tablets, with access to enterprise collaboration, communication and virtual desktop tools.
"It's another [unified communications] endpoint. Everything you can do on the 7-inch Cius today you can do on a 5-inch as well. The use cases are, some people just want something they can put in their pocket," Fontana said.
For instance, smaller-screen Cius devices could resemble smartphones and be alternatives to older devices like Cisco's old IP phones which are currently popular portable devices for voice and video.
The company this week introduced a model of its current Cius 7-inch device for AT&T's 4G network. The company will also introduce a Cius for Verizon's LTE network soon, Fontana said.

DoS Protection on Cisco Routers

The Cisco router is one of the most versatile High End routing machines. It is one of enterprise’s networking devices. If you take a look at Cisco website under the Routers Product Category, you will notice that the Cisco 7600 can be used in Data Centers, in Service Provider networks, in WAN aggregation or as Internet Edge router. In Service Providers can be used as Provider Edge (PE) in IP MPLS networks aggregating many Customer Edge (CE) router devices. Its modularity and high port capacity allows the 7600 to work as both Layer2 aggregation and as Layer3 high performance router.

In Service Provider networks one of the main concerns of network administrators is to protect the networking infrastructure from Denial of Service attacks. These DoS attacks are actually the most serious and popular security threat against Service Providers. buy used router Botnets are frequently the main source of such attacks. ICMP flooding, UDP flooding, spoofed addresses DoS, SYN attacks etc are a few examples of DoS or DDos (Distributed Denial of Service) attacks. Fortunately the Cisco 7600 router has many robust features and mechanisms to protect itself from such attacks.

In the company that I work (Service Provider) we have already implemented several security protection features on 7600 which are really effective against DoS attacks. A summary of the DoS protection mechanisms on 7600 follows below:

• Security Access Control Lists (ACL): Applied on interfaces to block traffic at Layer3/4 layers.
• QoS Rate Limiting: Using class-maps and policy-maps you can apply rate limiting to specific type of traffic (e.g ICMP)
• uRPF (unicast Reverse Path Forwarding): protects against spoofing attacks. sell cisco routers
• Traffic Storm Control: Protects against broadcast storm attacks.
• TCP Intercept: Protects against SYN attacks.
• Hardware-Based Rate Limiters: Work on PFC3 engines. These rate limiters protect the MSFC routing engine from various packets that can overload its CPU (configured with the mls rate-limit command)
• Control Plane Policing (CoPP): Again used for protection of the MSFC routing engine by applying rate limiting to packets that flow from the data plane to the control plane.

Of course in addition to the above you must not forget other important security mechanisms such as strong password policy, proper Authentication and Accounting, refurbished cisco router logging, SNMP security, Routing Protocols security (MD5 authentication in OSPF, BGP etc) etc. All of these technical issues must be based on a thorough and carefully written security policy.

What 6 Hardware Components Are Used in a Network

A computer network is formed by a few basic hardware elements. These devices link computers together in a format that enables them to exchange data with each other, sell refurbished cisco or with services like printers and fax machines.

Network Adapter

The most essential piece of hardware to link a computer to a network is a network adapter. This originally was manufactured on a separate board and slotted into an expansion slot on the motherboard of the computer. For this reason, the network adapter is often still called a network interface card, sell used cisco equipment even though it is usually integrated into the motherboard of modern computers. The network adapter translates data formats between the requirements of computers and the requirements of the network medium (either cable or radio waves).

Cable

Most networks in the world are connected by cable, despite the new popularity of wireless networks. The most common standard for network cable is called Ethernet. This was invented by Xerox, but the management of the standards is now the responsibility of the Institute of Electrical and Electronics Engineers (IEEE). sell cisco equipment Ethernet guidelines are published under the code 802.3. The most common configuration of network cable in the world today is called Unshielded Twisted Pair.

Hub

The hub is the simplest piece of equipment that can form a network. Every device in the network connects to a port on the hub via a dedicated cable (one cable per device). The hub has a series of sockets -- these are the ports. sell cisco used Any signal arriving on one port is automatically copied onto all other ports. The hub pays no attention to the destination address of any arriving data. It is also called a repeater because it repeats arriving data onto all other outlets.

Switch

A switch looks the same as a hub and it receives connections to networked devices in the same way. However, the switch examines arriving data packets and finds a destination address in the packet header. It associates an address with each of its ports. The arriving data is copied onto only that port bearing that address. Each port's address is, cisco sell in fact, the MAC address of the network adapter operating in the computer or device at the other end of the cable plugged into that port.

Bridge

Bridges are switches with only two ports. There is often confusion between switches and bridges. However, if it has more than two ports, it is a switch. Switches are also called multi-port bridges. The purpose of a bridge is to connect two segments of a network together. selling cisco equipment Network segmentation is a solution to a problem of network congestion where the network contains many computers. Bridges can also connect together dissimilar network media, such as cable and wireless segments.

Router

Hubs, switches and bridges operate within a network. Routers carry data beyond one network and across other to reach a destination that is not immediately connected. sell used equipment Routers operate with IP addresses and work together to form a chain passing data all over the world. A router must be connected to at least two networks in order to pass data beyond the boundaries of one network.

Wholesale Cisco Network Hardware

For Cisco resellers, wholesaling Cisco network hardware from some Cisco suppliers like Routerswitch.com is a better choice than purchasing single one from retailers.

One of the main reasons for buying wholesale Cisco equipment is that you get to save money. Held at the cost of buying in bulk is less because you can get a bigger discount for network hardware you bought or get the VIP service for wholesale customers.

If you are looking for an effective way to save money without compromising the quality of Cisco network hardware that you buy, wholesale Cisco hardware is a great choice. You know, most buy Cisco suppliers provide wholesale service for clients who want to buy certain CISCO items, offering biggest discount, free shipping, earlier delivery, etc.

Nowadays, due to fast development of internet, and to make shopping more convenient and easier, online store is a smart choice to select used Cisco network hardware you need. Because they list detailed purchasing guide, preferential price and full info of every cisco item, which can help you buy cheaper used Cisco equipment.

All in all, wholesaling used Cisco hardware (such as Cisco routers, especially for business and enterprises, Cisco switches: Catalyst 2960, 3560, 3750, 4500 and 6500, Cisco firewall: Cisco ASA 5500 series) benefit you more, biggest discount, competitive price, VIP service, free shipping, special gift, earlier delivery, etc. all these are only for wholesalers. So if necessary, wholesale Cisco network equipment is the best choice for reseller.
