Transport Agnostic - capability is achieved by splitting the control/management ‘planes’ from the data ‘plane’, using software defined networking (SDN) mechanisms to dynamically redirect traffic to the best transport, as opposed to having control/management/data on the same ‘plane’. The users/edge devices delegate (are agnostic) the tasks of assigning transport addresses/routes/protocols/mechanisms are used. From a security point of view, users/edge never access the control/management ‘planes’!

Cognitive Network (CN)

In communication networks, cognitive network is a new type of data network that makes use of cutting edge technology from several research areas to solve some problems current networks are faced with. Cognitive network is different from cognitive radio as it covers all the layers of the OSI model. Cognitive Network | Wikipedia

Multiprotocol Label Switching (MPLS)

Multiprotocol Label Switching (MPLS) is a networking technology that enhances the efficiency and speed of data transmission across networks by using labels to route packets instead of traditional IP addresses. This technology is particularly useful in large networks where the traditional routing methods can become complex and inefficient. MPLS operates independently of the underlying IP addressing and routing protocols, allowing for more flexible and efficient routing of traffic.

MPLS works by assigning labels to packets, which are then used to determine the path the packet should take through the network. This label-switched path (LSP) is determined by the first device (usually a router) that processes the packet, which then forwards the packet along the LSP to its destination. This process is much faster and more efficient than traditional routing methods, which require each device in the path to perform a routing lookup for each packet.

MPLS supports a variety of protocols and technologies, including IP, ATM, and Frame Relay, and it interfaces with existing routing protocols such as RSVP and OSPF. It also provides mechanisms for traffic engineering, quality of service (QoS), and the creation of virtual private networks (VPNs) both at Layer 2 and Layer 3.

In addition to improving network performance, MPLS also offers features like traffic engineering, which allows for the optimization of network paths based on various constraints such as bandwidth availability, and the creation of VPNs that can transport different types of traffic over the same network infrastructure.

MPLS is widely used in enterprise and service provider networks to deliver advanced, value-added services over a single infrastructure. It can be integrated seamlessly with existing infrastructure and supports a wide range of platforms, making it a versatile solution for both service providers and enterprises.

For example, in a service provider network, MPLS can be used to aggregate subscribers with differing access links on an MPLS edge without changing their current environments. This allows for the delivery of a wide variety of services over a single infrastructure, including Layer 3 VPNs, Layer 2 VPNs, Traffic Engineering, QoS, GMPLS, and IPv6.

In summary, MPLS is a powerful technology that enhances network efficiency and performance by using labels to route packets, supporting a wide range of protocols and technologies, and offering advanced features like traffic engineering and VPN creation.

Towards application aware networking
Featuring: Beth Cohen, NFV/SDN Network Product Strategy, Verizon SD-WAN is the first step towards application aware networking, but intelligent networking is still very much in its infancy. Not only do telecoms networks need to respond to the applications they run, but the applications themselves need to be better at responding to the network. Meanwhile, work continues at a rapid rate to minimize the number of NFVi architectures available and make their compatibility with VNFs more straightforward and faster for CSPs to implement.

Network Functions Virtualization (NFV)

Youtube search... ...Google search

NFV or Virtual Network Function (VNF) allows network operators to manage and expand their network capabilities on demand using virtual, software based applications where physical boxes once stood in the network architecture. This makes it easier to load-balance, scale up and down, and move functions across distributed hardware resources. With continual updates, operators can keep things running on the latest software without interruption to their customers. On the road to NFV deployment | Ericsson

For example, a virtual session border controller could be deployed to protect a network without the typical cost and complexity of obtaining and installing physical network protection units. Other examples of NFV include virtualized load balancers, firewalls, intrusion detection devices and WAN accelerators. ...The NFV framework consists of three main components:

  1. Virtualized network functions (VNFs) are software implementations of network functions that can be deployed on a network functions virtualization infrastructure (NFVI).
  2. Network functions virtualization infrastructure (NFVI) is the totality of all hardware and software components that build the environment where NFVs are deployed. The NFV infrastructure can span several locations. The network providing connectivity between these locations is considered as part of the NFV infrastructure.
  3. Network functions virtualization management and orchestration architectural framework (NFV-MANO Architectural Framework) is the collection of all functional blocks, data repositories used by these blocks, and reference points and interfaces through which these functional blocks exchange information for the purpose of managing and orchestrating NFVI and VNFs.

The building block for both the NFVI and the NFV-MANO is the NFV platform. In the NFVI role, it consists of both virtual and physical processing and storage resources, and virtualization software. Network function virtualization | Wikipedia

Dynamic Service Chaining for SDN NFV
Kishore Inampudi, A10 Networks In talk focus on framework for dynamic L4-L7 services in NFV/SDN environments. The modern service provider and data center networks demand cloud delivery model for agile and cost-effective rollout of services for revenue generation. There are some proposals to incorporate service insertion in the emerging SDN and NFV environments. However, the current methods are sub-optimal, complex and inflexible in delivering automated end-to-end service delivery. In a virtualized cloud environment, service delivery requires intelligence in the network for policy-based traffic handling and differentiated services. Dynamic service chaining is a fundamental component in building an on-demand and scalable model for policy enforcement. This session will cover following topics: 1. NFV & Service chaining use cases 2. Challenges with existing solutions 3. Opportunities with dynamic service chaining 4. Policy Enforcement model in SDN/NFV environment 5. Dynamic Service Chaining Architecture & Design considerations 6. Benefits of Dynamic Service Chaining
