BT's IP Clear service provides a secure and reliable corporate IP Virtual Private Network (VPN) using its Multi-Protocol Label Switching (MPLS) infrastructure. Key benefits of IP Clear include a full range of access types from leased lines to ADSL, optimal support for converged voice and data applications, any-to-any connectivity between sites, increased cost-effectiveness, greater scalability and flexibility, and high resilience ensured by BT's autonomous MPLS network.

Segment routing is a technology that is gaining popularity as a way to simplify MPLS networks. It has the benefits of interfacing with software-defined networks and allows for source-based routing. It does this without keeping state in the core of the network and needless to use LDP and RSVP-TE.
“MPLS is that it’s a technique, not a service.”
The fundamental concept behind MPLS is that of labeling packets. In a traditional routed IP network,
each router makes an independent forwarding decision for each packet based solely on the packet’s
network-layer header. Thus, every time a packet arrives at a router, the router has to “think through”
where to send the packet next.
VRF (Virtual Routing and Forwarding) is a technology that allows multiple instances of a routing table to
co-exist within the same router at the same time. This increases functionality by allowing network paths
to be segmented without using multiple devices. Because traffic is automatically segregated, VRF also
increases network security and can eliminate the need for encryption and authentication. Internet
service providers (ISPs) often take advantage of VRF to create separate virtual private networks (VPNs)
for customers; thus the technology is also referred to as VPN routing and forwarding. Because the
routing instances are independent, the same or overlapping IP addresses can be used without
conflicting with each other.

Description:
Networks are moving toward simplification, increased operational efficiency, and programmability using technologies such as software-defined networking. Cisco continues to demonstrate innovation by introducing the concept of segment routing in the data center, making the network more intelligent and adaptive to the applications running on top of it. Segment routing delivers application-optimized network transport. Encoding the path information directly at the source (that is, either at the virtual switch or at the top of rack) and using per-app policies, segment routing puts control in the hands of the network operators by empowering them to create secure, adaptive, and optimal paths based on the requirements of the application itself.
Please join us in the session to learn how Cisco is helping organizations increase network efficiency by allocating resources on demand and optimizing the network to better support business-critical applications, all while preserving security.
Agenda
Topics to discuss include:
- Introducing segment routing
- Why the need for application-optimized transport
- Features and benefits of segment routing
- Differences between segment routing and MPLS transport
- Relevance of segment routing in the data center
- Use cases and applicability of segment routing
- Summary and conclusion
Building DataCenter networks with VXLAN BGP-EVPNCisco Canada
The session specifically covers the requirements and approaches for deploying the Underlay, Overlay as well as the inter-Fabric connectivity of Data Center Networks or Fabrics. Within the VXLAN BGP-EVPN based Overlay, we focus on the insights like forwarding and control plane functions which are critical to the simplicity operation of the architecture in achieving scale, small failure domains and consistent configuration. To complete the overlay view on VXLAN BGP-EVPN, we are going to the insides of BGP and its EVPN address-familiy and extend to about how multiple DC Fabric can be interconnected within, either as stretched Fabrics or with true DCI. The session concludes with a brief overview of manageability functions, network orchestration capabilities and multi-tenancy details. This Advanced session is intended for network, design and operation engineers from Enterprises to Service Providers.

Cisco Live! :: Introduction to Segment Routing :: BRKRST-2124 | Las Vegas 2017Bruno Teixeira
This session provides an overview of the segment routing technology and its use cases. This new routing paradigm provides high operational simplicity and maximum network scalability and flexibility. You will get an understanding of the basic concepts behind the technology and its wide applicability ranging from simple transport for MPLS services, disjoint routing, traffic engineering and its benefits in the context of software defined networking. Previous knowledge of IP routing and MPLS is required.
Getting clocks to agree on the time is tricky. Getting them to agree on the time better than 100 nanoseconds is even trickier.
In this talk I will provide an introduction to the basic principles of the Precision Time Protocol (PTP) and how it can be used to precisely synchronize computers over a LAN.
