IEEE 802.11 is part of the IEEE 802 set of LAN protocols, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) Wi-Fi computer communication in various frequencies, including but not limited to 2.4, 5, and 60 GHz frequency bands.
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
A wireless network is a computer network that uses wireless data connections between network nodes.
3Com Corporation was a digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers.
A network switch is a computer networking device that connects devices on a computer network by using packet switching to receive, process, and forward data to the destination device.
A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network. Encryption is a common though not an inherent part of a VPN connection.
The data layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment. The data link layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the physical layer.
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and usually takes action by blocking, re-routing, or logging it accordingly. While deep packet inspection can be used for innocuous reasons such as making sure that data is in the correct format or checking for malicious code, it can also be used for more nefarious motives such as eavesdropping and censorship. There are multiple headers for IP packets; network equipment only needs to use the first of these for normal operation, but use of the second header is normally considered to be shallow packet inspection despite this definition.
In telecommunications networks, a node is either a redistribution point or a communication endpoint. The definition of a node depends on the network and protocol layer referred to. A physical network node is an active electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communications channel. A passive distribution point such as a distribution frame or patch panel is consequently not a node.
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services by encapsulating these into IP packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation of formerly telephone-centric networks toward NGN.
IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to add wireless access in vehicular environments (WAVE), a vehicular communication system. It defines enhancements to 802.11 required to support Intelligent Transportation Systems (ITS) applications. This includes data exchange between high-speed vehicles and between the vehicles and the roadside infrastructure, so called V2X communication, in the licensed ITS band of 5.9 GHz (5.85-5.925 GHz). IEEE 1609 is a higher layer standard based on the IEEE 802.11p. It is also the basis of a European standard for vehicular communication known as ETSI ITS-G5.
Barracuda Networks, Inc. is a company providing security, networking and storage products based on network appliances and cloud services. The company's security products include products for protection against email, web surfing, web hackers and instant messaging threats such as spam, spyware, trojans, and viruses. The company's networking and storage products include web filtering, load balancing, application delivery controllers, message archiving, NG firewalls, backup services and data protection.
A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi.
Token Ring local area network (LAN) technology is a communications protocol for local area networks. It uses a special three-byte frame called a "token" that travels around a logical "ring" of workstations or servers. This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention-based access methods.
Allied Telesis is a network infrastructure/telecommunications company, formerly Allied Telesyn. Headquartered in Japan, their North American headquarters are in San Jose, California. Founded in 1987, the company is a global provider of secure Ethernet & IP access solutions and an industry leader in the deployment of IP triple play networks over copper and fiber access infrastructure.
In intelligent networks (IN) and cellular networks, service layer is a conceptual layer within a network service provider architecture. It aims at providing middleware that serves third-party value-added services and applications at a higher application layer. The service layer provides capability servers owned by a telecommunication network service provider, accessed through open and secure Application Programming Interfaces (APIs) by application layer servers owned by third-party content providers. The service layer also provides an interface to core networks at a lower resource layer. The lower layers may also be named control layer and transport layer.
OpenFlow is a communications protocol that gives access to the forwarding plane of a network switch or router over the network.
Hewlett Packard Enterprise and its predecessor entities have a long history of developing and selling networking products. Today it offers campus and small business networking solutions through its wholly owned company Aruba Networks which was acquired in 2015. Prior to this, HP Networking was the entity within HP offering networking products.
HP FlexNetwork Architecture is a network architecture developed by Hewlett-Packard to provide networking services and a consistent network architecture for the data center, campus and branch offices. It was developed to support technologies such as virtualization and cloud computing. HP FlexNetwork Architecture encompasses four products: HP FlexFabric, used to improve performance and latency in virtualized server environments; HP FlexCampus, used to connect wired and wireless networks in environments that support mobile and rich media applications; HP FlexBranch, used to improve network service delivery in branch offices; and HP FlexManagement, a single-pane-of-glass management platform that spans all of the FlexNetwork Architecture.
Meru Networks was a supplier of wireless local area networks (WLANs) to healthcare, enterprise, hospitality, K-12 education, higher education, and other markets. Founded in 2002 and headquartered in Sunnyvale, California, United States, the company made its initial public offering in March 2010.
