IP Routing Services

IP routing services are divided into five areas:

Port Routing

VLAN Routing

Routing Information Protocol (RIP)

Open Shortest Path First (OSPF) Protocol

Proxy Address Resolution Protocol (ARP)

Port Routing

The first networks were small enough for the end stations to communicate directly. As networks grew, Layer 2 bridging was used to segregate traffic, a technology that worked well for unicast traffic, but had problems coping with large quantities of multicast packets. The next major development was routing, where packets were examined and redirected at Layer 3. End stations needed to know how to reach their nearest router, and the routers had to understand the network topology so that they could forward traffic. Although bridges tended to be faster than routers, using routers allowed the network to be partitioned into logical subnetworks, which restricted multicast traffic and also facilitated the development of security mechanisms.

An end station specifies the destination station’s Layer 3 address in the packet’s IP header, but sends the packet to the MAC address of a router. When the Layer 3 router receives the packet, it will minimally:

Look up the Layer 3 address in its address table to determine the outbound port

Update the Layer 3 header

Recreate the Layer 2 header

The router’s IP address is often statically configured in the end station, although the 7000 Series Managed Switch supports protocols such as DHCP that allow the address to be assigned dynamically. Likewise, you may assign some of the entries in the routing tables used by the router statically, but protocols such as RIP and OSPF allow the tables to be created and updated dynamically as the network configuration changes.

7000 specifications

The NETGEAR Nighthawk R7000 is a high-performance dual-band Wi-Fi router that stands out in the crowded market of home networking devices. Designed to cater to gamers, streamers, and smart home enthusiasts, it provides robust connectivity and a range of features aimed at ensuring seamless internet experiences.

One of the R7000’s standout features is its dual-band capability, which allows it to operate on both the 2.4 GHz and 5.0 GHz frequency bands. This flexibility offers users the ability to connect devices that require stable connections without interference, such as smart TVs, gaming consoles, and smartphones. With speeds of up to 1900 Mbps, the R7000 supports even the most bandwidth-intensive activities, enabling multiple devices to stream, game, and browse simultaneously without lag.

The router is powered by a powerful dual-core processor, which enhances its overall performance and allows for efficient multitasking. With the inclusion of Beamforming technology, the R7000 intelligently directs Wi-Fi signals toward connected devices instead of broadcasting them in all directions. This focused connection improves network efficiency and range, ensuring that users can maintain strong links even in larger homes.

Security is a paramount concern for NETGEAR, and the R7000 addresses this with robust features. It includes built-in NETGEAR Armor, an advanced cybersecurity solution that protects connected devices from online threats. Additionally, parental controls and guest network options provide users with enhanced privacy and management capabilities, allowing families to regulate internet access and safeguard their networks.

The device is compatible with Amazon Alexa and Google Assistant, providing users with the ability to control their networks through voice commands. The R7000 also supports ReadySHARE USB access, enabling easy file sharing between devices by simply connecting a USB storage device to the router.

Setup and management of the R7000 are straightforward, thanks to the intuitive NETGEAR Nighthawk app. This mobile application allows users to manage their Wi-Fi settings, monitor connected devices, and perform speed tests on-the-go.

In summary, the NETGEAR Nighthawk R7000 is a feature-rich router designed for demanding internet users, combining speed, security, and user-friendly management to enhance the overall connectivity experience. Whether for gaming, streaming, or managing smart homes, the R7000 remains a strong contender in the networking landscape.
