Our Core Network Infrastructure Solution provides your business with an end-to-end solution spanning the entire lifecycle of your network. From Preparation, Planning, Design, Deployment, Operations, and Optimization, ECCOM has the resources and expertise necessary to support your company’s critical in-frastructure.
With trends such as Collaboration & Web 2.0 technologies, the Internet has had an unprecedented im-pact upon society and how we conduct business. New business models and emerging technologies have enabled enterprises a wide range of service capabilities and service levels in which they are able to offer their customers with the long-term goal of enhancing their customer’s experience and customer satisfac-tion.
Utilizing a Service-Oriented Network Architecture approach, you can accelerate the integration of your business applications and processes, increase efficiency and better utilization of your network resources, and enable your IT to provide a better experience for your employees and customers. A “service-oriented” based network architecture fundamentally requires your various departments such as applications development, systems, and networking units to work closer together, communicate more effectively with one another, and strengthen collaboration within the enterprise. Network designers need to be engaged early on to provide guidance and input when faced with your company’s new business strategy to ensure that it will meet network and security requirements. While new business initiatives and models may cause dramatic change within your existing infrastructure, it may be necessary in order for your business to achieve its’ overall architecture goals.
Given the context of IT resource consolidation, companies are establishing large Data Centers for the centralized storing and processing of critical business information, supporting the business’ core compe-tencies and operations, and serving as the critical epicenter of the enterprise. Other parts of the enter-prise such as Enterprise Headquarter campus networks, branch offices & remote offices, strategic partners & third-party extranets, Internet & VPNs rely on the Data Center for the services that it provides.
Enterprise Data Center Networking
A modular or hierarchical designed Data Center network offers you the ability to separate func-tionality from the underlying hardware infrastructure. This flexibility allows businesses to segment their infrastructure into various logical areas focusing on a specific business function. Some typical examples of this type of segmentation may include things like: a live production network, core backbone networking, WAN & Internet access, or branch office/regional office connectivity; but designs will depend on your company’s overall strategic goals and objectives. Using a layered-based approach, each functional area can be abstracted into three layers: a Core layer, a Converged layer, and a Access layer. Each area connects across the Core layer to communicate between all the other areas inside the network.
Enterprise Network Redundancy
Businesses need to plan for backup and redundancy strategies, including plans for on-site and off-site disaster recovery centers to ensure business continuity and minimal interruption in the event of a disaster. When planning for disasters, redundancy strategies should include backups for storage, processing systems, and network equipment; and be housed in a separate physical facility. While your enterprise network topology and data center network should be similar to your backup center, it does not have to be a completely identical. It will depend on your business’ disaster recovery requirements, your current environment, and what resources are available. For example, some backup centers are deployed for only critical segments of a customer infra-structure; and connectivity between the production and backup data centers utilize DWDM, SONET/SDH, Ethernet fiber connections to support high-speed low-latency applications such as synchronous data replication.
Enterprise Headquarters Networking
Typically, a business’ headquarters will house many of a company’s upper management staff, and the infrastructure will need to support their needs. Management will need to receive and act on critical business data, perform strategic planning, and execute corresponding processes. When the data center resides on-site the enterprise headquarter network this is not a problem. However, some deployments have their data center hosted off-site. In these types of environments, the Enterprise Headquarter network should utilize DWDM, SONET/SDH, or Ethernet fiber to connect to their data center (or backup data center). The Enterprise Headquarter network should also utilize a modular or hierarchal design to facilitate this process.
Branch Office/Remote Office Networking
Branch office/Remote office networking is an important aspect of the enterprise. Some typical deployment models may categorize their branch offices into different tiers, such as tier one and tier two branch offices. Tier one branch offices connect directly to the data center across the corporate WAN, while tier two branch offices connect to tier one branch office networks. Depending on your business’ requirements, this may vary. Branch office networks also typically utilize a modular or hierarchal design.
Enterprise Core Backbone Networking
Connectivity between various enterprise branch offices, headquarter/regional offices and enterprise data center network is achieved via the Enterprise WAN Backbone. Some connection types utilized to connect into the WAN backbone include point-to-point DDN lines, SDH, ATM, and Frame relay lines. Branch offices will also typically utilize redundant WAN lines connecting through different Service Providers, implementing data prioritization (QoS policies), and connection redundancy strategies to ensure critical data traffic is transported across the WAN.
Partner & Third-Party Extranets
Enterprises often require closer integration when working with strategic partners or third-parties, utilizing the WAN or extranets as the primary means of data transport. Access by third parties to the data center is implemented at the Access Area, and often has a low security level requiring access to be controlled with a firewall, NAT, and other measures to ensure the security of the data center.
The use of web applications by businesses help provide customers greater convenience such as on-line banking systems. Customers connect to the data center web server and gain access to related services. While employees access corporate internal resources through the Internet using Virtual Private Networks (VPN), establishing a secure end-to-end channel for communication as if they were on your company’s internal network. Internet Access security levels are typically very low, and require the use of layer 2 firewalls to ensure data center security.
These are some of the logical components that comprise the overall Enterprise Network Archi-tecture. However, network architectures may vary depending on your company’s business model, and requirements. We have deep understanding of the needs of today’s enterprise customers. Leveraging our re-sources, knowledge, and wealth of experience, we help businesses build and optimize all com-ponents of their network. From the Data Center, across the Internet or VPN, to your Headquarters and branch offices; we can help you build a powerful IP-based network architecture connecting your customers, partners, and employees together. Anytime. Anywhere.
