A backplane or backplane system is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. It is used to connect several printed circuit boards together to make up a complete computer system. Backplanes commonly use a printed circuit board, but wire-wrapped backplanes have also been used in minicomputers and high-reliability applications.
Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints, the labels identify established paths between endpoints. MPLS can encapsulate packets of various network protocols, hence the multiprotocol component of the name. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL.

Brocade was an American technology company specializing in storage networking products, now a subsidiary of Broadcom Inc. The company is known for its Fibre Channel storage networking products and technology. Prior to the acquisition, the company expanded into adjacent markets including a wide range of IP/Ethernet hardware and software products. Offerings included routers and network switches for data center, campus and carrier environments, IP storage network fabrics; Network Functions Virtualization (NFV) and software-defined networking (SDN) markets such as a commercial edition of the OpenDaylight Project controller; and network management software that spans physical and virtual devices.
Advanced Telecommunications Computing Architecture is the largest specification effort in the history of the PCI Industrial Computer Manufacturers Group (PICMG), with more than 100 companies participating. Known as AdvancedTCA, the official specification designation PICMG 3.x was ratified by the PICMG organization in December 2002. AdvancedTCA is targeted primarily to requirements for "carrier grade" communications equipment, but has recently expanded its reach into more ruggedized applications geared toward the military/aerospace industries as well. This series of specifications incorporates the latest trends in high speed interconnect technologies, next-generation processors, and improved Reliability, Availability and Serviceability (RAS).
Riverstone Networks, was a provider of networking switching hardware based in Santa Clara, California. Originally part of Cabletron Systems, and based on an early acquisition of YAGO, it was one of the many Gigabit Ethernet startups in the mid-1990s. It is now a part of Alcatel-Lucent and its operations are being wound down via a Chapter 11 filing by their current owners.
Passport Carrier Release (PCR) is a version of the Passport Switch software designed to run in telecommunications carrier environments. It was formerly developed by Nortel. After the sale in 2009 of most Nortel's assets, the passport SW is still used in several products of Alcatel-Lucent, Ericsson and Kapsch.
Allied Telesis is a network infrastructure–telecommunications company, formerly Allied Telesyn. The company is Headquartered in Japan, and has other branches in San Jose, California. The company was established in 1987, as a provider of secure Ethernet & IP access equipment along with IP triple play networks over copper and fiber access infrastructure.
The Cisco Catalyst 6500 is a modular chassis network switch manufactured by Cisco Systems from 1999 to 2015, capable of delivering speeds of up to "400 million packets per second".
The Avaya Ethernet Routing Switch 8600 or ERS 8600, previously known as the Passport 8600 or the Accelar 8000, is a modular chassis combination hardware router and switch used in computer networking. The system, originally designed and manufactured by Nortel, was manufactured by Avaya from 2009 until 2017. The system provided the 10G Ethernet equipment backbone for the 2010 Winter Olympics games, providing service for 15,000 VoIP Phones, 40,000 Ethernet connections and supporting 1.8 million live spectators. The system is configurable as a 1.440 Terabit Switch cluster using SMLT and R-SMLT protocols, to provide high reliability cluster failover.
Dell Force10, was a United States company that developed and marketed 10 Gigabit and 40 Gigabit Ethernet switches for computer networking to corporate, educational, and governmental customers. It had offices in North America, Europe, and the Asia Pacific region.
The Juniper T series is a line of core routers designed and manufactured by Juniper Networks. The T-series core router family comprises the T320, T640, T1600, T4000, TX Matrix, and TX Matrix Plus, designed for high-end and core networks with throughput from 320 Gbit/s to 25.6 Tbit/s with a maximum forwarding rate of 30.7 billion pps. The JCS1200, the industry’s only independent control plane scaling system, brings virtualization to the core of the network. The TX Matrix Plus provides transport scale up to 25 Tbit/s. The T-series routers run Junos OS.
Juniper E-Series is a series of broadband services routers or edge routers manufactured by Juniper Networks. The E series was originally developed by Unisphere Networks, which Juniper acquired in 2002. These routers provide multiple services including broadband remote access server, broadband video services, dedicated access, 802.11 wireless subscriber management, VOIP, internet access, security services, network address translation (NAT) etc. on a single platform. The carrier-class architecture of E-series routers allows to combine Broadband Remote Access Server (B-RAS) and dedicated access capabilities on a single and integrated platform. The E-series routes runs on JUNOSe software compared to other series of routers of Juniper which runs on JUNOS.
