Description |
---|---|
BIOS |
BIOS is firmware used to perform hardware initialization during the booting process, and to provide runtime services for operating systems and programs. The BIOS firmware comes pre-installed on a personal computer's system board, and it is the first software to run when powered on. |
Cisco IMC |
The Cisco Integrated Management Controller (IMC) is the management service for the C-Series servers. CIMC runs within the server. You can use a web-based GUI or SSH-based CLI to access, configure, administer, and monitor the server. |
DPDK |
The Data Plane Development Kit (DPDK) is a set of data plane libraries and network interface controller drivers for fast packet processing. |
DTLS |
Datagram Transport Layer Security (DTLS) is a communications protocol that provides security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. |
IPSec |
Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers over an Internet Protocol network |
LACP |
Link Aggregation Control Protocol (LACP) is a protocol for the collective handling of multiple physical ports that can be seen as a single channel for network traffic purposes. |
LLDP |
Link Layer Discovery Protocol (LLDP) is a vendor independent link layer protocol used by network devices for advertising their identity, capabilities to neighbors on a LAN segment. |
MIB |
Management Information Base (MIB) is a database of the objects that can be managed on a device. The managed objects, or variables, can be set or read to provide information on the network devices and interfaces. |
NETCONF |
A Network Configuration Protocol (NETCONF) is a protocol defined by the IETF to install, edit, and delete the configuration of network devices. |
NGIO |
Next Generation Input/Output (NGIO) |
PnP |
Plug and Play (PnP) increases speed and reduces complexity of device deployments. |
Port Channels |
Port channels combine individual links into a group to create a single logical link that provides the aggregate bandwidth of up to eight physical links. |
RADIUS |
Remote Authentication Dial-In User Service (RADIUS) is a networking protocol, operating on port 1812 that provides centralized Authentication, Authorization, and Accounting management for users who connect and use a network service. |
REST API |
Representational state transfer (REST) suggests to create an object of the data requested by the client and send the values of the object in response to the user. |
Service Chaining |
Service chaining allows data traffic to be rerouted through one or more services, such as firewall, load balancer, and intrusion detection and prevention (IDP) devices. |
SNMP |
Simple Network Management Protocol (SNMP) is a framework used for managing devices on the internet. It provides a set of operations for monitoring and managing the internet. |
SPAN |
Switched Port Analyzer (SPAN) feature, which is sometimes called port mirroring or port monitoring, selects network traffic for analysis by a network analyzer. |
Spanning Tree |
Spanning Tree Protocol (STP) is a Layer 2 protocol that runs on bridges and switches. The main purpose of STP is to ensure that you do not create loops when you have redundant paths in your network. |
SR-IOV |
Single Root I/O Virtualization (SR-IOV) allows multipleVMs running a variety of guest operating systems to share a single PCIe network adapter within a host server. SR-IOV allows a VM to move data directly to and from the network adapter, bypassing the hypervisor for increased network throughput and lower server CPU burden. |
TACACS |
Terminal Access Controller Access-Control System (TACACS) refers to a family of related protocols handling remote authentication and related services for networked access control through a centralized server. |
UEFI |
The Unified Extensible Firmware Interface (UEFI) is a specification that defines a software interface between an operating system and platform firmware. |
virtio |
Virtual input/output (virtio) is a virtualization standard for network and disk device drivers where just the guest's device driver "knows" it is running in a virtual environment, and cooperates with the hypervisor. |
VM |
A virtual machine (VM) is an emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. |
VNF |
Virtual Network Functions (VNFs), the software version of network appliances such as a router, firewall, load-balancer etc |
