Store-and-Forward:

Store-and-Forward switching will wait until the entire frame has arrived prior to forwarding it. This method stores the entire frame in memory. Once the frame is in memory, the switch checks the destination address, source address, and the CRC. If no errors are present, the frame is forwarded to the appropriate port. This process ensures that the destination network is not affected by corrupted or truncated frames.

Cut-Through:

Cut-Through switching will begin forwarding the frame as soon as the destination address is identified. The difference between this and Store-and-Forward is that Store-and-Forward receives the whole frame before forwarding. Since frame errors cannot be detected by reading only the destination address, Cut-Through may impact network performance by forwarding corrupted or truncated frames. These bad frames can create broadcast storms wherein several devices on the network respond to the corrupted frames simultaneously.

DWL-2100AP Introduction:

D-Link AirPlus Xtreme GTM series of high-speed devices now capable of delivering transfer rates up to 15x faster than the standard 802.11b with the new D-Link 108G. With the new AirPlus Xtreme G DWL-2100AP Wireless Access Point, D-Link sets a new standard for wireless access points.

The DWL-2100AP Wireless Access Point also supports SNMP v.3 for better network management with the provided Wireless AP Manager software that manages network configuration and firmware upgrades. For Enterprise networks, the DWL-2100AP supports network administration and real-time network traffic monitoring via D-Link’s D-View Network Management software.

The DWL-2100AP features WDS (Wireless Distribution System) that can be configured to perform in any one of five modes: a Wireless Access Point, a Point-to-Point (PtP) bridge with another DWL-2100AP, a Point-to-Multipoint (PtMP) bridge, a Repeater for range extension, or as a Wireless Client. The WDS feature makes the DWL-2100AP an ideal solution for quickly creating and extending a wireless local area network (WLAN) in offices or other workplaces, or even at hotspots.

Editor’s review:

The D-Link Wireless N Router DIR-615 annihilates any excuse you may have to not move to Wireless-N (300Mbps speed cap). With a price of about $40, the router is cheaper than even some Wireless-G routers–which cap at 54mbps–such as the Linksys WRT110. And you’ll get a lot for the price. While the DIR-615 lacks Gigabit Ethernet and USB ports, it has everything else you’d want from a Wireless-N router. It has decent wireless throughput speed and range and accompanies an easy-to-use Web interface and a generous set of networking features. If you are looking for upgrade your network to Wireless-N and don’t need any fancy features, look no further than the essential DIR-615. It is a great entry-level Wireless-N router that gives you possibly the biggest bang for your buck among wireless routers.

D-Link DIR-615 Wireless N Router User Reviews

Features:

The DIR-615, as expected from the price, doesn’t have a lot of wireless features found in high-end D-Link routers, such as Dual-Band, GuestZone (which enables you to make a separate wireless network for guests), or SharePort (which allows for use with USB devices). It does have a long list of networking features and a very responsive and intuitive Web interface.

Starting with the DIR-685, D-Link incorporates a Capcha with the log-in of the Web interface. This provides more security, but if you hate having to read the distorted text, which is how the Capcha determines that the input is not generated by a computer, this could be a nuisance. The DIR-615 offers numerous network features found in other Wireless-N routers from D-Link. You can then set up manual port forwarding–where you map information coming to a certain port to another computer in the network–or use the router’s preset settings for different applications and services such as instant messengers, BitTorrent, IP phone software, virtual servers, and so on. It also offers a comprehensive set of parental control tools including Network Filter, Access Control, Web site Filter, and Inbound Control. These tools allow you to control the network and limit access to the Internet by specific criteria, such as setting a computer to only allow access to instant-messenger services during a certain period of time. The router also lets you customize its firewall to allow some services, but not others.

D-Link DIR-615 works great for me! We tried a Linksys WRT-120 but it was not wrking well. The D-Link is easy to set up and does everything we need. For us, an outstanding product.

It Works great for us! Easy to set up and install. Even if the DIR-615 were more expensive it would be a super value. After spending 5 hours with Linksys “live chat” our WRT-120 still would not work. We use ours for Laptops and Nintendo Wii and Nintendo DSI.

I registered just to say it works fine for me. I used the set-up CD. I connected it wireless to a Blue Ray (Wireless N) for streaming Netflix. No problems…streaming wirelessly within a hour. (On the Blue Ray I had to disable wired Dynamic IP after doing a firmware update via ethernet on the BD) Excellent signal strength…. Wireless G laptop immediately recognized the network, excellent signal strength. Ran a ethernet cable to my Directv HD DVR….recognized the connection immediately.
No lock-ups, no reboots, no error codes, no tech support calls.
Haven’t had a reboot yet.
Everyone’s experience and equipment is different, but I wanted to chime in with how it went for me.

On Windows 7, it is a quick, easy and flawless install. Good solid connect during heavy downloads. Steady, quick during on-line gaming such as World of Warcraft.

Many had perhaps not followed the simple instructions. Read the instructions and follow the prompts from the provided CD install disk. Full configured by itself without intervention on my behalf on a newly installed Windows 7 operating system. Excellent security settings.

I had attempted to install two different manufacture routers Netgear and a Linksystem unit. Neither would function. The perceived cheapness of the DIR-615, is no reason to pass by the unit. It is an excellent starter unit or even that of an upgrade over an older and none functioning unit.

Now Price Range

$50.71 – $64.99
