What is Ethernet ring topology?
The Ring Topology: In a ring network each Ethernet switch is connected to two other switches forming a ring. This provides two benefits: Each switch has a redundant connection (link) into the network. The cabling infrastructure is more cost effective than using an aggregation switch at a central location.
What is Eaps extreme?
EAPS (Ethernet automatic protection switching), invented by Extreme Networks and submitted to IETF as RFC3619, is used to create a fault tolerant topology by configuring a primary and secondary path for each VLAN. The master node transmits the ring detection packets via the control VLAN through the primary port.
What is ITU-T g 8032?
8032 Ethernet Ring Protection Switching Feature Overview and Configuration Guide. 8032 is an International Telecommunication Union (ITU) standard for Ethernet Ring Protection Switching (ERPS). It prevents loops on a per-VLAN basis with networks that are wired in a simple ring topology, and (with G.
What is erps protocol?
Ethernet Ring Protection Switching (ERPS) is a protocol defined by the International Telecommunication Union – Telecommunication Standardization Sector (ITU-T) to eliminate loops at Layer 2. Because the standard number is ITU-T G. 8032/Y1344, ERPS is also called G. 8032.
Which is better ring or star topology?
Star Topology due to its simple structure is less complex as compared to Ring Topology. On other hand due to more complexity in nodes arrangement Ring Topology is considered as more complex. Star Topology is cost efficient as compared to Ring Topology. However, Ring Topology is costlier as compared to Star Topology.
What is the difference between star and ring topology?
A star topology is a network topology where each individual device of the network is attached to one central node whereas a ring topology is a network configuration in which device connections create a circular data path. Thus, this is the main difference between star and ring topology.
What protocol is used to transmit Eaps packets?
Encapsulation Protocol
EAPS frames are encoded using the Extreme Networks’ Encapsulation Protocol.
What is MRP ring?
Media Redundancy Protocol (MRP) is a standards-based protocol used in Ring topologies to avoid single points of failure by providing a recovery time of 10ms or less. In a ring network, each Ethernet switch is connected to a minimum of two other switches to form a ring.
What is Carrier Ethernet service?
Carrier Ethernet extends Ethernet from the local area network (LAN) to the wide area network (WAN), enabling companies to connect their Ethernet LANs to service provider networks via the same Ethernet interface they use to attach every device in the network.
Which hardware is used in LAN?
To connect a computer or device to a local area network (LAN) , several hardware components are required: a network interface card (NIC) or wireless network interface controller (WNIC) a transmission medium , either wired or wireless.
How is LAN different from WAN?
LAN has a higher data transfer rate whereas WAN has a lower data transfer rate. LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings, while WAN is a computer network that covers a broader area. The speed of LAN is high whereas the speed of WAN is slower than LAN.
What is the difference between hub and switch?
KEY DIFFERENCES A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.
