An HTTP proxy is similar, and may be used for the same purpose when clients are behind a firewall and are prevented from making outgoing TCP connections to servers outside the firewall. However, unlike the SOCKS server, an HTTP proxy does understand and interpret the network traffic that passes between the client and downstream server, namely the HTTP protocol. Because of this the HTTP proxy can ONLY be used to handle HTTP traffic, but it can be very smart about how it does it. In particular, it can recognize often repeated requests and cache the replies to improve performance. Many ISPs use HTTP proxies regardless of how the browser is configured because they simply route all traffic on port 80 through the proxy server.

End point address: IP address, MPLS, SD
MPLS = Multiprotocol Label Switching is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints, the labels identify established paths between endpoints.
Enterprise networks carry a varied range of traffic, such as video, voice, and data. Each one of these traffic classes has its own set of performance requirements and traffic characteristics. A wisely carved out network framework places the right elements to facilitate sufficient resources to each traffic class in order to guarantee the required quality-of-service (QoS) and incremental performance improvements.
A Hybrid WAN architecture for example, combines broadband and MPLS, allowing network managers to keep mission critical traffic on the MPLS network and offload best effort traffic like e-mail and remote backups. This is certainly a better use of bandwidth than running everything over the MPLS network.
SD-WAN - combines all protcols, traffic into a single software-defined flexible appliance including routing, security, firewall for a single control plane
r>> users going to cloud platforms more than data center now
v>> independent of the ISP so you can mix providers as needed, where needed
v>> mix protocols including wireless for failure if needed
f>> QOS controlled well in private net but SD-WAN has dynamic QOS optimization services that normally do well for MOST use cases on latency
h>> migrate apps to SD-WAN as needed moving P2P

Introduction to Software Defined Technologies: The video introduces software-defined technologies, including Software-Defined Networking (SDN), Software-Defined WAN (SD-WAN), and Software-Defined Access (SD-Access), discussing their roles and components in Cisco's solutions.
Traditional Networking Devices: Discusses traditional networking devices like routers and switches, which operate on three planes: data plane (handling data forwarding), control plane (running algorithms like OSPF or spanning tree protocol), and management plane (for configuration and administration).
Shift to SDN: SDN represents a shift from traditional networking, moving from a distributed control plane, where each device has its own control plane, to a centralized model where the control plane is managed by an SDN controller.
Role of APIs in SDN: Emphasizes the use of Application Programming Interfaces (APIs) in SDN, particularly southbound interfaces (SBIs) for communication between the controller and devices, and northbound interfaces (NBIs) for communication between the controller and applications.
Intent-Based Networking: Highlights the concept of intent-based networking in SDN, allowing administrators to express network intentions through applications rather than configuring each device individually.
Cisco's SDN Solutions: Distinguishes Cisco's SDN solutions in different contexts: Cisco APIC (Application Policy Infrastructure Controller) in data centers as part of Cisco's ACI (Application Centric Infrastructure) and Cisco DNA Center for enterprise networks.
SD-WAN Overview: Introduces SD-WAN, noting its advantages over traditional WAN by creating virtual, secure, and efficient overlay networks, thus overcoming inefficiencies like backhauling through a headquarters or data center.
Cisco’s Viptela-Based SD-WAN Solution: Cisco's SD-WAN solution, based on technology from their Viptela acquisition, includes components like vSmart for centralized control and vBond for network orchestration and zero-touch provisioning.
SD-WAN Network Infrastructure: Details the structure of SD-WAN networks, distinguishing between the physical underlay network and the virtual overlay network, with secure IPsec tunnels forming the data plane.
SD-Access as ACL Replacement: Describes SD-Access as an advancement over traditional access control lists (ACLs), enabling more dynamic policy enforcement using security groups and identities, irrespective of physical location.
Cisco's SD Access Architecture: Breaks down Cisco's SD Access solution into layers, starting from the physical layer (infrastructure devices) up to the management layer, indicating its comprehensive approach to network management.
Closing Remarks and Learning Opportunities: Concludes with a reminder of the educational opportunities available for learning more about these technologies, encouraging viewers to explore further through Cisco's training courses.

As the number of IoT devices continues to grow, keeping them all connected to the internet in an affordable way has proven difficult which is why Napster’s Co-creator Shawn Fanning, Sproutling founder Chris Bruce and Amir Haleem set out to build the word’s first peer-to-peer wireless network. Their company, Helium has created its own hotspot that is used to power the People’s Network. In addition to providing IoT devices with connectivity, the Helium hotspot also rewards its users with a new cryptocurrency that can be used to offset the initial cost of the device.
To learn more about the Helium hotspot and the peer-to-peer wireless network it powers, TechRadar Pro spoke with Helium’s CEO Amir Haleem.
