A fiber or dense wavelength division multiplexing-based solution is often needed to extend storage between two data centers. Do you want to learn more about Ciena's products? I understand I can unsubscribe at any time. In another example of inter-data center interconnect, is if a certain video is getting a lot of views, the video is not only kept in its central location, but copies of the video are pushed to metro data centers where access is quicker because it’s stored closer to the user, and the traffic doesn’t tie up long haul networks. 1500 characters remaining. In this blog, I'll look at different options for DCI and how well they fulfill our design requirements for a DCI. They can snoop ARP responses and cache locally so that when the next host ARPs for the MAC, it will already be known by the OTV device, which can answer locally. Our mission: to expand opportunities for... We build networks that are ‘fit for flexibility’ today, and into the future. Register now for Interop, May 2-6, and receive $200 off. However, VPLS doesn't help control unicast flooding, reduce broadcasts, or police BUM traffic. Copyright © 2020 Ciena Corporation. This design guide describes an Arista solution for providing simple, robust, and cost-effective datacenter interconnection (DCI) that enables layer-2 services to be bridged between multiple sites over existing layer-3 IP networks. 4.2.2 Data-Center Interconnection Networks. These technologies will flood frames no questions asked if the destination MAC address is not in the MAC address table. It's a Cisco proprietary protocol that can run over any transport as long as there is IP connectivity. … LONG-TERM STABILITY . Preferably, there should be support for multicast, but it can run in unicast mode as well. Since VXLAN can ride over any IP transport, it's possible to extend L2 domains and use VXLAN as a DCI. Ethernet over MPLS (EoMPLS) is a point-to-point technology that uses MPLS to encapsulate Ethernet frames. All data centers are essentially buildings that provides space, power and cooling for network infrastructure. Number 8860726. It’s been that way since we were founded in 1998 to provide a vendor-neutral meeting place where network and internet service providers could connect as they built the early internet. VLANs can then be extended over the port channel between the data centers. The multi-tier approach includes web, application, and database tiers of servers. The most connected data centers at the network core in preeminent locations throughout the USA. The only chance to police traffic would be to implement a policer on the port leading to the pseudo wire. In recent years, the scale of the DCN has constantly increased with … This is where our journey begins. OTV devices also help reduce broadcasts. There was a problem with your video. Another version is available. Most network designers would prefer that data center interconnection over wide area networks (WAN) be performed at layer 3, without layer-2 connectivity spanning data centers. Marketplace. ECOSYSTEM PARTNER. Learn about technologies and vendors critical to the Future of Networking at a two-day summit presented by Packet Pushers at Interop Las Vegas this spring. All rights reserved. The implementation of VXLAN may or may not support caching of ARP responses and it’s an optional feature that has to be enabled for broadcast reduction. Thank you! Design > Networks. Choose a DCI design that is validated to meet your needs. Interconnection networks are composed of following three basic components − 1. It’s also possible for an organization to deploy VPLS in their network. 4.2.4 Interconnection of Modular Data Centers.

Integrated building ownership and Meet Me Room management protect your business for the long-term. While Equinix is perhaps best known for running more than 175 data centers worldwide, our core business is interconnection. Organizations need a truly flexible SD-WAN solution to meet current and evolving business needs and digital transformations demands. This interconnectivity between separate data centers enables them to work together, share resources and/or pass workloads between one another. 2. In fact, neither will help with controlling of unicast flooding. With VSS, a loop-free topology is created between the data centers. We use advanced security equipment, techniques and procedures to control and monitor access to our IBX data centers. Und viertens Sicherungsmaßnahmen, die dafür sorgen, dass dieses Kabel oder dieser logische Übertragungsweg (bei mehreren Nutzern pro Kabel) nur denen zugänglich ist, die auch darauf zugreifen dürfen. Our low-profile building design allows a high level of security within the data center. Comments are limited to 1500 characters. Data centers have proliferated in recent years—there are now more than 7,500 around the globe, with 2,600 packed into the top 20 global cities alone. Dazu braucht man nicht viel. Behind those solutions, however, network engineers are working hard to make everything work as it should, creating a skills gap in this area within the enterprise. Overlay Transport Virtualization (OTV) is one of the few technologies designed for DCI. OTV helps control unicast flooding because it works  on the assumption that there are no silent hosts, so all hosts should be known. All frames can be forwarded regardless of VLAN (port mode) or VLANs can be selectively forwarded (VLAN mode). vPC and VSS create loop-free topologies, but it’s important to note that they are simply VLAN extension technologies without any optimizations designed for DCI. A DCN enables the deployment of resources centralization and on-demand access of the information and services of data centers to users.
