The objective of NFV along with SDN is to gain agility, dynamic scaling and flexibility in network infrastructure which are making their way to adapt technology transformation. Basically, with SDN, operators or network administrators will get full control over their network and with NFV architecture, network equipment will be replaced with Virtualized infrastructure. Hence, VNFs represent software implementation of network devices which are virtualized and packed in virtual machines which are scalable and movable.
Multiple vendors are now offering VNFs as solution to present various network functions. This way, software in form of VNFs built for different network functions can work individually or combined together, further allowing service providers to rapidly develop and deploy new services for customers and achieve growth in revenue and be competitive in respective market.
Here is the basic VNF functional model. Figure: Functional model of VNF. VNFs are software images developed to run as network function. VNF providers design software into components and VNFs are made by collectively packaging multiple software components.
VNF structure made up of multiple VNFCs depends on factors like prioritization of performance, scalability, reliability, security and other non-functional goals, the integration of components from other VNF Providers, operational considerations, the existing code base, etc. Their interfaces and functionalities can be improved or changed dynamically due to the need for innovation in services delivered on NFV.
There are still challenges that exist in developing VNFs which run seamlessly on any NFV infrastructure, one that can be easily on-boarded, scale, highly adaptable and flexible in nature. The reasons being —. Due to such challenges, manual efforts are needed each time to configure, update and testing for VNFs and this is one of the roadblocks for service providers to realize the NFV implementation success.
Apart from above challenges there are few more obstacles related to VNFs. Like consumption of hardware resources by VNF to be highly available is on higher side, multi tenancy is not supported, VNFs cannot be reused or shared, APIs are not provided for automating tasks like scaling, configuring, patching and updating versions. Current innovation in software development is to make any application a cloud-native; means applications can be API driven, micro-services oriented, containerized, dynamically managed.
Cloud native capabilities allow developers to build final product in no time and managing all the software components will be highly automated. Applying cloud-native capabilities will overcome many challenges which are vendors and service providers are facing. Cloud-native VNFs enables standard and simplified management of VNF components and further reduces the power consumption and frees up unnecessary allocated hardware resources as tasks are fragmented i.
NFV architecture offers a great promise to provide agile, flexible and automated network. Highly automated, containerized, micro-services based and dynamically orchestrated VNFs will be a huge boost to realize NFV success.

Service providers have their own workflows in infrastructure.Whether a company is choosing new software for its employee computers or selecting a supplier for its primary product line, a vendor manager leads the process of exploring the selection of available vendors and deciding which offers the optimal cost and quality for the company.
This leadership role also involves maintaining a positive relationship with each vendor and utilizing the expertise of other purchasing professionals to research, analyze and monitor vendors and their products. While you may work long hours and have to travel at times, working in vendor management can lead to a generous salary and offer opportunities to work in a broad range of industries.
A vendor management role heavily involves working closely with vendors to make purchasing decisions and maintaining relationships with vendors for as long as the company uses them. Specific vendor management roles and responsibilities include visiting vendors to inspect products, communicating with vendors to ask any product or price questions, negotiating contracts to get the desired pricing, analyzing multiple vendors to decide which to use for a particular product and providing leadership over purchasing agents and buyers.
This role requires you to be a good communicator and negotiator and have interpersonal skills to effectively maintain vendor relationships. Math and decision-making skills are important for selecting vendors that best fit the company's needs.
In addition to having already worked in a purchasing role for several years, a vendor manager typically needs a bachelor's degree in supply chain management or another business field. These degree programs often include courses on topics beyond purchasing, such as marketing, finance and management, that provide vendor managers a broader business background.
Vendor managers usually don't need a professional certification, but options include the Compliance Education Institute's Certified Regulatory Vendor Program Manager certification and the International Association for Contract and Commercial Management's Supplier Relationship Manager credential.
Half of the vendor managers were paid more than that, while half earned less. Vendor managers find positions in diverse companies that use vendors for its supplies, products and services.
These include logistics companies, retailers, wholesalers, information technology companies, professional and scientific services firms and government. Vendor managers mostly stay on-site with the purchasing team but occasionally do travel to have meetings with potential and current vendors. Like for many management occupations, overtime is sometimes necessary depending on business needs.
Vendor manager salaries are often generous from the start and include profit sharing and bonuses that increase over time. Senior management opportunities in procurement are possible with significant experience. In MayPayScale. While the BLS states that purchasing professionals as a whole are expected to experience a job decline between andthe outlook is better for purchasing managers, with a 5 percent growth and 4, new jobs expected during that decade.
Purchasing managers remain important for coordinating procurement in companies and face less of an impact from automation than purchasing agents and buyers do.
There can be competition, however, since there are limited purchasing manager positions available since the occupation size is small.

What Does a Vendor Manager Do?Increase service velocity, improve network flexibility and scaling, and reduce your total cost of ownership.
Network functions virtualization NFV architectures provide the necessary network flexibility to enable new service delivery models and elastic network scaling to reduce total cost of ownership.
Fundamentally, NFV begins with the shift toward the virtualization of network components currently deployed on purpose-built hardware. As you evolve your networks to NFV, the abstraction of the control-plane and data-forwarding plane simplifies the creation and management of new services.
At the same time, you benefit from a programmable network based on industry standard open APIs that give you greater flexibility and agility. F5 packaged NFV solutions include the F5 VNF Manager, which enables a fully automated solution with full lifecycle management—from service instantiation to auto-scaling to decommission. Whether your goal is to deploy a completely virtualized network or a hybrid network where only some of the functionality will be virtualized, BIG-IP products are available as both carrier-grade, purpose-built hardware and virtual editions VEs on COTS hardware.
F5 makes network virtualization easier with fully automated packaged NFV solutions.

What type of network function can be orchestrated and automated? What type of network services can be orchestrated and automated? This solution does not orchestrate physical domains such as transport or non-virtualized RAN domains.
These domains typically have their own orchestration platform for integrated end-to-end service orchestration. What type of automation can the solution perform? VMware Telco Cloud Automation supports both human and system-triggered automated workflows and policies for network functions and services.The communications business is one of the most dynamic industries with continual changes occurring in technology, services, competition, and business models.
They want to reap the benefits of cloud economies by bringing the same technologies that power the cloud to the telco cloud. The lure of 5G and IoT is a powerful incentive to get there quickly. Once the CSP has decided to launch a service, there is the initial planning stage which includes a number of activities.
These include the identification of the VNFs and VNF vendors, understanding the licensing agreements, procuring the VNFs, drafting the high-level design and working out the capacity and performance plans. Once the planning phase concludes, the very first operational step is to onboard the relevant VNFs from multiple vendors that make up the network service. The problem is that there is no standard way to instantiate, configure, and operationalize these multi-vendor VNFs.
Today, it is a very expensive, complex and time-consuming effort to onboard VNFs. VNFs are difficult to onboard because there are no common configuration protocols, interfaces, and policies. Alternatively, CSPs have their own workflows and DevOps tools and would like to integrate the Onboarding process with their workflows to make sure the VNF operates successfully in their environment.
Both vendors and CSPs have to keep up with the rapid iteration in standards and open source projects as they gain traction. These specifications form the basis for many of the requirements and attributes that are being implemented by VNF vendors. There is also work being done on the packaging format that includes not only the structure of the package but all the elements that make up the package such as image file, VNF Descriptor, pre and post-processing scripts, monitoring drivers, etc.
But until such time that there is convergence within the standards bodies and adoption by the industry, CSPs need to consider tools today that can address the disparity in formats and packaging.
Typically, VNF Onboarding involves the following high-level activities with each activity having multiple tasks or sub-activities. The experience of onboarding many different types of VNFs from numerous vendors who are part of this partner ecosystem was the genesis for the VNF Onboarding Factory. The above onboarding activities include ongoing testing in a staging environment before it can be taken to production deployment.
Testing includes smoke test, full functional tests, assurance, performance, capacity tests, etc. We encourage you to share your comments on this post.

The replacement of the QH payroll system must take a place in the front rank of failures in public administration in this country.
It may be the worst. It also shows the potential financial impacts when vendors are managed poorly and communication breaks down. In an ultra-competitive global marketplace, businesses must look at creative ways to extract more value from suppliers, while simultaneously reducing risk and upholding quality.
Simply beating them down on price year after year is not a sustainable strategy.
Basics of Virtual Network Functions (VNFs) & Challenges
This is where vendor management comes in. Done well, it's a repeatable, effective method for developing and monitoring third-party providers of goods and services, in order to derive as much value as possible from contracts and to build mutually-beneficial long-term relationships.
In this article, we're going to take you through five key areas of vendor management, offering practical, actionable advice. Wherever you identify your organisation being along this continuum, there is likely to be improvements you can make. Key to reaching stages 4 and 5 of the process is measurement and tracking relevant metrics that can be improved.
The Institute for Supply Management ISM has identified five categories of supplier management activity that should be measured and managed to achieve a level of excellence. Information about the amount of money spent with each vendor on an annual basis is one key indicator of his importance to your business. Data needs to be collected from all types of financial transactions, summarised and then classified in a way that makes sense to you, and from which you can draw conclusions to help identify your key suppliers.
You might find suppliers that you have limited awareness of are receiving more significant sums of money than other higher profile ones. There is no one perfect way to segment vendorschoose a method that works for you.
Key to this exercise is centralising your data into a spreadsheet or ideally, a dedicated vendor management solution. Large organisations will often run VRM programs. These can help but will often require some significant investment into people and resources and so may only make sense for those larger businesses, when focusing on strategic suppliers or if automation can be achieved using a supplier management solution. Many organisations have a problem with working openly with suppliers thinking that sharing operational and financial information leaves them in a weaker negotiating position.
The opposite may be the case.Brawlhalla bot
Sharing of new technologies and innovative ideas can lead to added value and cost savings for both parties.
This is harder to measure but may be counted in terms of number of supplier contacts and how often business reviews are conducted. Where there is poor or no focus on managing performance, all actions are reactive and unlikely to help improve delivery.Uk49 bankers
