Baystack Access Node and Access Node Hub Data Sheet BAYSTACK ACCESS NODE AND ACCESS NODE HUB WORKGROUP PRODUCTS The Bay Networks BayStack™ Access Node (AN®) and Access Node Hub (ANH™) routers cost-effectively connect small remote offices and ensure network availability while minimizing network operating costs. Typical connectivity requirements of remote offices are supported by the BayStack AN router’s LAN interfaces (Ethernet and Token Ring) and serial interfaces (Synchronous, one T1/FT1 data service unit/channel service unit (DSU/CSU) or 56/64 Kbps DSU/CSU adapter module, and one ISDN Basic Rate Interface (BRI)). The fully managed BayStack ANH supports either eight or twelve 10BASE-T repeater ports, as well as Synchronous interfaces, one or two Synchronous and ISDN BRI interfaces, and one T1/FT1 DSU/CSU or 56/64 Kbps DSU/CSU adapter module, reducing equipment and management complexity. In all BayStack AN and ANH configurations, the serial interfaces provide remote office network design flexibility. For mission-critical applications, they facilitate Dial Backup and Bandwidth-on-Demand support. In addition, Dial-on- Demand functionality enables a BayStack AN to extend network availability on an as-needed basis to small remote sites, minimizing WAN service costs. Optionally, Synchronous interfaces can be used for Synchronous Data Link Control (SDLC), allowing both IBM SNA and multiprotocol LAN traffic over one consolidated WAN link to the internetwork backbone. The BayStack AN and ANH easily integrate with the enter- prise internetwork by supporting Bay Networks Routing Services (BayRS™), which provides support for all major LAN and WAN protocols. The Motorola MC68360 micro- processor, used in the BayStack AN and ANH router’s highly integrated design, easily maintains high forwarding and filtering rates regardless of the number of protocols and network interfaces used—even when processing SNMP management inquiries.

  • Ethernet Switches and Crossover Cables
    Ethernet Switch A switch is something that is used to turn various electronic devices on or off. However, in computernetworking, a switch is used to connect multiple computers with each other. Since it is an external device it becomes part of the hardware peripherals used in the operation of a computer system. This connection is done within an existing Local Area network (LAN) only and is identical to an Ethernet hub in terms of appearance, but with more intelligence. These switches not only receive data packets, but also have the ability to inspect them before passing them on to the next computer. That is, they can figure out the source, the contents of the data, and identify the destination as well. As a result of this uniqueness, it sends the data to the relevant connected system only, thereby using less bandwidth at high performance rates. The first Ethernet network switch was pioneered by Kalpana (computer networking equipmentmanufacturing company in Silicon Valley established by an entrepreneur of Indian origin, Vinod Bharadwaj) in 1990. Switches operate at Layer 2 of the OSI Model; the Data-Link Layer. This is in contrast to routers, which operate at Layer 3 of the OSI Model, the Network Layer. A switch stores the MAC Address of each and every device which is connected to it. The switch will then evaluate every frame that passes through it. The switch will examine the destination MAC Address in each frame. Based upon the destination MAC Address, the switch will then decide which port to copy the frame to. If the switch does not recognize the MAC Address, it will not know which port to copy the frame to.

  • 20 Computer Terms Every Mac User Should Know
    macworld 2/14/14, 10:23 AM This is from a macworld.com article dated July 4, 2013… 20 computer terms every Mac user should know Wired and wireless networking Magic is the word some people use to describe the ability to connect your computer and mobile devices wirelessly to the Internet. But other—and more specific—means and protocols include the following. Ethernet: This wired standard is used in local computer networking (that is, in networked devices that are located in the same physical space and share a common router address). An ethernet connector looks like a large telephone plug; and like a telephone plug, it snaps into its host receptacle. The most common forms of ethernet Page 1 of 9 macworld 2/14/14, 10:23 AM are 10Base-T, 100Base-T, and 1000Base-T (also known as gigabit ethernet). These forms differ considerably in speed. 10Base-T operates at a limit of 10 megabits per second (mbps), 100Base- T bumps that limit up to 100 mbps, and 1000Base-T offers a limit of 1000 mbps (or one gigabit per second). Ethernet connections are handled through Cat-5 and Cat-6 cables like this. Ethernet can be faster than a Wi-Fi connection, depending on the devices you’re using. If, for example, your Mac supports gigabit ethernet but a device it’s connected to supports only 100Base-T, your Mac must move data between it and that device at the slower speed. The other advantage ethernet offers is range. You can string a very long ethernet cable that allows you access to a network where a Wi-Fi signal would have long since Page 2 of 9 macworld 2/14/14, 10:23 AM petered out.

  • Comparative Analysis of Performance of Hub with Switch Local Area Network (LAN) Using Riverbed in University of Technology (Utech),Jamaica
    International Journal of Computer Networks & Communications (CNCIJ) Vol.01, No.1, January 2019 Comparative Analysis of Performance of Hub with Switch Local Area Network (LAN) Using Riverbed in University of Technology (Utech),Jamaica. Christopher Udeagha,R. Maye, D.Partrick,D. Humphery,D.Escoffery,E.Campbell School of Computing & Information Technology, Faculty of Engineering & Computing, UTech, Papine, Jamaica. Abstract Hubs and switches have been actively used devices in computer networks vision, over two (2) decades. As results, numerous approaches have been used with varying degrees of success to evaluate the performances of these devices in computer networks. A class of approach that shown substantial promise is one that gives clear and predictive results regarding the numbers of workstations, servers and categories of cables used in the network is by riverbed academic edition, version 17.5. A common theme in this green technique, to this approach is by creating two scenarios. In the first scenario, about seven (7) to ten (10) workstations were connected to web server via a hub. The relevant performance statistics were collected at both workstations and the server. The same was done in the second scenario except that the hub was replaced with a switch, which will facilitate the connections between the workstations and the server. Simulations in the laboratory-using riverbed version 17.5, was done to obtain the statistical comparative results of these two scenarios. This approach has shown to outperform other existing methods in comparative analysis of performance of hub with switch in a local area network (LAN).
