Networking componentsHub

An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment through cabling 10/100base. In large network configurations Hubs have been replaced by segment switches.

Hubs have in most cased been replaced with Wirelesshub routers within a workgroup defined LAN.

Networking componentsRouters (Core)

A core network, or network core, is the central part of a Data center network that provides various services that are connected by the access network. Typically the term refers to the high capacity communication facilities that connect primary nodes.

They help consolidate separate LAN, SAN, and server cluster network environments into a single Ethernet fabric. Backed by a broad system of industry-leading technology partners, Cisco Nexus 5000 Series Switches are designed to meet the challenges of next-generation data centers, including the need for dense multisocket, multicore, virtual machine–optimized services, in which infrastructure sprawl and increasingly demanding workloads are commonplace. Cisco Nexus 5000 Series Switches provide:

• Architectural flexibility to support diverse business and application needs

• Infrastructure simplicity to decrease the total cost of ownership (TCO) Increased agility and flexibility for traditional deployments with easy migration to virtualized, unified, or high-performance computing (HPC) environments

Cisco Nexus 5000 Series Switches provide a unified, converged fabric over 10Gigabit Ethernet for LAN, SAN, and cluster traffic. This unification enables network consolidation and greater utilization of previously separate infrastructure and cabling, reducing by up to 50 percent the number of adapters and cables required and eliminating redundant switches. This infrastructure displacement also lowers power and cooling costs significantly, especially for rack-optimized servers similar to blade servers

Networking componentsBridge

A network bridge is a network device that connects multiple network segments. In the OSI model bridging devices acts in the first two layers, below the network layer. There are four types of network-bridging technologies: simple bridging; multiport bridging; learning, or transparent bridging; and source route bridging. An example of Wireless and LAN networksegments are:

The Cisco Aironet ® 1400 Series Wireless Bridge creates a new benchmark for wireless bridging by providing a high-performance and feature-rich solution for connecting multiple LANs in a metro area. Building a metropolitan area wireless infrastructure with the Cisco Aironet 1400 Series Wireless Bridge provides deployment personnel with a flexible, easy to use solution that meets the security requirements of wide area networking professionals. Designed to be a cost-effective alternative to leased lines, it is engineered specifically for harsh outdoor environments, yet also works well in indoor deployments. The Cisco Aironet 1400 Series Wireless Bridge is the premier high-speed, high-performance outdoor bridging solution, providing features such as:• Support for both point-to-point or point-to-multipoint configurations

Networking componentsGateway

Gateway is a router or a proxy server that routes between networks with different protocols.

Provides IP network address translation from internet to private networks.

Specific Gateway appliances within Cloudsprovide translation for cloud storage APIs

with SOAP or REST with block FC or iSCSI and file based access with NFS and CIFS.

Example of another Gateway use Cisco AS5400 Series Universal Gateways support three primary universal gateway configurations: 8 CT1/CE1, 16 CT1/CE1, and 1 CT3. Two 10/100 autosensing Ethernet LAN ports are provided for LAN connectivity. Two high-speed serial ports support Frame Relay, Point-to-Point Protocol (PPP), and High-Level Data Link Control (HDLC) backhaul. All backhaul interfaces support Hot Standby Router Protocol (HSRP), and all cards are hot-swappable for carrier-class resiliency. Integrated signaling link termination (SLT) is available to provide Cisco distributed message transfer part (MTP) SS7 signaling functionality.

The Power of Network Segmentation

The FortiGate-310B/-311B series appliances answer the call of growing enterprise

networks by integrating a purpose-built security processing ASIC, known as

the FortiASIC Network Processor, into the FortiGate system to deliver security

throughput at switching speeds.

Eight hardware accelerated interfaces (expandable to 12)

allow networks to enforce firewall policy between network

segmentation points for layered security with switch-like performance.

An additional purpose-built ASIC, known as the FortiASIC Content

Processor, provides additional acceleration for content intensive

security technologies such as intrusion prevention and antivirus scanning.

The inclusion of modular expansion slots allow for even more flexibility,

offering additional ASIC-accelerated ports for additional throughput or disk-based

storage for local logging and content archiving.

Networking componentsWireless AP

In networking today, a wireless access point (AP) is a device that allows wireless devices to connect to a wired network using WIFI, or related standards. The AP usually connects to a router (via a wired network or fiber network) as a standalone device, but it can also be an integral component of the router itself.

Typical uses for access points today are providing wireless support within a corporate office environment. In public spaces, access points provide public “hotspots for internet access by users with laptops or mobile devise thru WIFi access.
