In the second part of my blog series I want to cover one of the main concerns that Services Providers are facing as they explore moving to NFV and that is performance and scalability. Common concerns I hear center around latency, throughput, queuing capabilities and security. These are valid concerns since SP’s have service level agreement (SLA’s) with the their customers which lead to penalties if performance drops below the SLA. So will a virtualized network function perform at the same level as a purpose built networking device? Read More »
InfoVista recently announced its support for Cisco’s Application Visibility & Control (AVC) as part of its Application Visibility Services solution for communications service providers (CSPs). I took some time out this week to speak with Christopher Cullan, product marketing manager for business services at InfoVista, to discuss the solution and specifically the significance of Cisco’s ISR-AX and AVC to his business.
Bob: Christopher, tell me what’s behind InfoVista’s investment in the Cisco AVC technology as part of your solution?
Christopher: Sure, by the way, you can call me Chris. Cisco AVC and the ISR-AX capability provides an attractive and simple architecture that takes advantage of the Customer Premise Equipment (CPE), and allows CSPs to offer customers a better service experience by enhancing the visibility of the service from an application perspective.
Bob: The application visibility?
Christopher: Yes, exactly—it’s a solution to the problem of the enterprises’ business-IT gap. Enterprise IT is constantly tasked to deliver greater agility to their business stakeholders, and it’s challenging for them to communicate with the business from an infrastructure perspective, including WAN services. The application is better understood and more tangible to the business because they experience it more directly (e.g. the business understands salesforce is slow today, versus the network latency is high). Having insight into not only what applications are traversing the WAN, between which users and systems and how much, but also the application performance itself, empowers enterprise IT to make better decisions and provide a greater experience to their stakeholders. In essence, it helps enterprises better align their IT to the needs of the business. Read More »
