Company Service

"Complex Networking"

The ATI “Complex Networking” service focuses on developing, supporting, and implementing the specialties of Wireless and Server Load Balancing for an organization. There are three (3) areas of focus that ATI specializes in: Design / Installation, Troubleshooting / Support and Network Documentation. These offerings include but are not limited to; 802.11a/b/g/n Wireless Networks (to include secure Wireless Roaming) and Server Load Balancing (Cisco ACE/CSS/CSM) for the data center (also the option of Cisco Global Server Load Balancing or Cisco Site Load Balancing can be used for hot-site creation (Disaster Recovery); see below).

 

 

Design and Installation
ATI’s Design and Installation service provides two of the top "World-Class Infrastructure" service offerings of the network world today. that are expertly designed and installed. We design and implement Cisco Airespace and Aironet gear and access points. In wireless networking the one rule that rings true is this; "You Get What You Pay For!". So the key is to do it RIGHT the first time. No one has the time to be chasing Rogue issues and Rogue Users.

Wireless: From the Whiteboard to the Boardroom
Striking the balance between Wireless Security and Wireless Roaming (walking around with your laptop and working, then losing connection). Wireless Security is no joke. Left unprotected, wireless could cost you millions (of even billions) in the amount of loss, damage and even intellectual theft of corporate information and secrets. On the other hand; a laptop that never leaves a desk is called a "PC". ATI's Fast Secure Wireless Roaming solutions allow your users to move around, roaming from access point to access point; securely and continuously. This is summarized by the statement;"Combine the mobility and flexibility users want from a wireless network with the security and management they require from a wired network."

The process works like this; Access points in many wireless LANs serve mobile client devices that roam from access point to access point throughout the installation. Some applications running on client devices require fast re-association when they roam to a different access point. Voice applications, for example, require seamless roaming to prevent delays and gaps in conversation.

During normal operation, security-enabled client devices mutually authenticate with a new access point by performing a complete security authentication, including communication with the main RADIUS server, thus providing not interruptions in quality or security!

Server Load Balancing for the Complex Data Center
The Cisco CSS, CSM and ACE products are specifically designed to provide robust application delivery (Layer 4 to 7) services for Internet and intranet data centers in six key areas:

1.)They introduces an intelligent, distributed architecture to help organizations meet the real-world scaling requirements of today's application infrastructure.

2.)They improves application and site availability and transaction integrity by introducing Adaptive Session Redundancy (ASR), an industry standard in stateful failover.

3.)They delivers the greatest flexibility of any content switch in its class for customizing combinations of ports, performance, and services.

4.)They scale secured application transaction performance through support of an integrated, high-capacity Secure Sockets Layer (SSL) module. Off-loading SSL onto the network improves the overall performance of the web and application server enabling better application performance.

5.)They provide an integrated high-capacity web application (Hypertext Transfer Protocol, HTTP) compression module. Web application (HTTP) compression improves application response time by 20 to 50%, off-load the compression from the server, which reduces server workload, and decreases the traffic traversing wide area networks (WANs), which reduces bandwidth requirements and improves overall application response times; improving productivity.

6.)The Cisco flexibility protects investments by enabling upgrades of performance, ports, and services to meet your current and future application demands.

As Web applications become increasingly more critical to business success, particularly in the areas of e-commerce, customer relationship management (CRM), and employee resource management (ERM), the performance, scalability, security, and availability of the application infrastructure become paramount concerns for IT and network managers. These requirements, in turn, drive the deployment of Web applications in tiers (layers).

The device and application requirements that determine how messages are routed are expressed in terms of policies, and these policies are configured on the content switch. For example, when you route messages to a group of firewalls, you might want to balance the load across the available firewalls and at the same time ensure that all messages associated with a particular application connection traverse the same firewall in both directions. The reason is that firewalls need to be able to statefully inspect all the packets associated with a connection in both directions.

When you route messages to application servers, you might want to balance the load across the application servers, with the additional constraint that all connections from a particular client get routed to the same application server until a particular transaction or set of transactions is complete.

*The Cisco Global Site Selector (GSS):
• Provides a resilient architecture that is critical for disaster recovery and multisite Web application deployments

• Offers flexible heterogeneous support for all Cisco SLBs and DNS-capable networking products

• Provides centralized command and control of the DNS resolution process for direct and precise control of the global load-balancing process

• Augments and offloads any DNS Berkeley Internet Name Domain (BIND) infrastructure to optimize content requests and delivery for all types of static and dynamic Web content

• Provides dedicated processing of DNS requests for greater performance and scalability

• Offers site persistence for e-commerce applications

• Offers two unique network proximity features that leverage Cisco Systems, Inc. routers and Layer 4-7 content switches that allows the Cisco GSS 4492R in real time, to direct content consumers to the closest data center

• Supports a Web-based GUI and DNS wizard to simplify DNS command and control

Troubleshooting and Support
Troubleshooting or supporting most networks can be a tricky situation. It is not uncommon for systems to not play nice together. That's where we come in. We are experts in quickly finding the issue and knowing the best path to resolution.

Wireless Support and Expert Problem Resolution
Operational support is a critical component of any organization. To enable an organization to manage and effectively implement the support process, it is imperative to have operational and support processes in place. Awesome Technologies staff will analyze an organizations business and technical requirements, then will document and implement a process that identifies each step of the support and operational process.

Server / Site Load Balancing Troubleshooting
Working with industry best practices, the ATI staff can aid an organization to troubleshoot the root of the problem. This process will ensure that all organizational security polices are followed, as well as ensure that all personal are well informed about the architecture. This happens many time in the data center; for instance Server Load Balancing and applications like PeopleSoft. We have handled tricky balancing with Oracle, PeopleSoft, BEA WebLogic and other silo'd applications. We are experts in integrating the Cisco CSS Load Balancer with almost every application around today.

Network Documentation
Every organization needs documentation to help provide guiding principles for the user community and for how business is done. These documents can span multiple sections of a customer environment such as:

• Core Network Drawings
• Packet Flows
• Port Scan Documents
• Sarbanes Oxley Report Generation
• PCI - Security Audit Compliance Documents
• Compliance with internal, state, of federal policies

ATI’s Documentation Development service helps an organization by investigating the network layout and documenting to the same. For most; documentation is the hardest part of any project and we agree. It is our pleasure to document (or adjust the existing documentation) to include any project work changes that have occurred. It is part of our technical installations. I can say from experience that this is the most critical part of planning and certifying a network or service. It has even saved jobs, by readily being able to show it
