4 What is MPLS MPLS: Multi-Protocol Label Switching
Any-to-any connectivity Supports existing Legacy Protocols Frame Relay, Pt to Pt, Ethernet, ATM, DSL Secure Layer 3 Routing using VPN’s and VRF’s Provides a Fully Meshed Network Solution Provides differentiated services Class of Service (COS) Allows for convergence of Voice, Data, Video networks Intranet/Extranet Verizon’s MPLS network is branded as Private IP MPLS (Multiprotocol Label Switching) is an IETF-defined protocol that overcomes some of the shortcomings of IP-based networks. MPLS is meant for service provider core networks or large enterprise networks. It brings traffic engineering, bandwidth management, and quality of service to IP networks. A form of MPLS is used to set up and manage wavelength optical circuits (lambdas) on the core optical networks of the Internet. MPLS's key feature is the ability to build virtual circuits across IP networks. These VCs are called label switched paths (LSPs). LSPs are similar to virtual circuits in ATM and frame relay networks. Labels are attached to packets, which help MPLS nodes forward the packet across an LSP. The labels are like tracking slips on express delivery packages. They contain an index into a forwarding table, which specifies the next hop for the packet. Nodes in the core MPLS network do not need to examine packets and perform next-hop routing tasks. The label carries the information that determines which path a packet should take. MPLS supports traffic engineering to provide traffic prioritization and QoS. For example, a path can be created that provides high bandwidth and low delay for "premium" customers who are willing to pay for it. In another example, multiple paths can be defined between two endpoints to provide load balancing and backup service in the event of a line failure. This is similar to using metrics in IP routing to force traffic in one direction or another, but it is much more powerful. Any to Any connectivity is the result of a Fully Meshed Network. How we achieve that fully meshed network is what we need to look at - depending on what technology we use, this will look different. Any location on the Verizon’s Private IP network can connect to any other location on the Verizon’s Private IP network. Important to realize that every location has to be hooked into the Verizon network. But, the outcome of fully meshed, means that every location can communicate with every other location directly. This is not as critical in networks where remote sites need only communicate with a single host site where all the servers and information is located. In networks with distributed servers and distributed databases, as well as networks with requirements to communicate between remote sites such as when applications such as Voice over IP are used, any-to-any connectivity becomes extremely beneficial. Layer 2/3 – The main point is that lower layers provide services to upper layers. Applications are the usual source of messages and data that are passed down through the protocol stack, but each protocol layer may also generate its own messages in order to manage the communication session. One other thing to note is that the lower-layer physical and data link protocols operate across physical point-to-point links while the transport layer protocols operate on end-to-end virtual circuits that are created across the underlying network. Layer 2 refers to the Data Link Layer of the Open Systems Interconnection (OSI) model. The data link layer defines the rules for sending and receiving information across a physical connection between two systems. Data links are typically network segments (not internetworks) and point-to-point links. Data is packaged into frames for transport across the underlying physical network. Some reliability functions may be used, such as acknowledgment of received data. In broadcast networks such as Ethernet, a MAC (Medium Access Control) sublayer was added to allow multiple devices to share the same medium. Layer 3 refers to the network layer of the Open Systems Interconnection (OSI) model. This layer provides internetworking services that deliver data across multiple networks. An internetwork addressing scheme assigns each network and each node a unique address. The network layer supports multiple data link connections. In the Internet Protocol suite, IP is the network layer internetworking protocol. In the IPX/SPX suite, IPX is the network layer protocol. In order to utilize the Private IP infrastructure, customers must utilize the IP protocol. If there is a requirement for other protocols to be used, those protocols must be ‘tunneled’ by the customer CE router within IP in order to be communicated across the Private IP infrastructure. QoS – network with quality of service has the ability to deliver data traffic based on desired characteristics such as a minimum amount of delay in an environment in which many users share the same network. QoS should not be confused with CoS (class of service). CoS - not to be confused with QoS (Quality of Service) - It is a way of classifying and prioritizing packets based on application type (voice, video, file transfers, transaction processing), the type of user (CEO, secretary), or other settings that ultimately classifies traffic into categories such as high, medium, and low priority. Low-priority traffic is "drop eligible," while high-priority traffic gets the best service. However, if the network does not have enough bandwidth, even high-priority traffic may not get through. Traffic engineering, which enables QoS, is about making sure that the network can deliver the expected traffic loads. CoS is a queuing discipline while QoS covers a wider range of techniques to manage bandwidth and network resources. CoS classifies packets by examining packet parameters or CoS markings and places packets in queues of different priorities based on predefined criteria. QoS has to do with guaranteeing certain levels of network performance to meet service contracts or to support real-time traffic. With QoS, some method is used to reserve bandwidth across a network in advance of sending packets. An intranet is a private network that is contained within an enterprise or company. It may consist of many interlinked local area networks. Typically, an intranet includes connections through one or more gateway computers to the outside Internet. The main purpose of an intranet is to share company information and computing resources among employees. Typically, larger enterprises allow users within their intranet to access the public Internet through firewall servers that have the ability to screen messages in both directions so that company security is maintained. When part of an intranet is made accessible to customers, partners, suppliers, or others outside the company, that part becomes part of an extranet. An extranet is a private network that uses the Internet Protocol and the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers, or other businesses. An extranet can be viewed as part of a company's intranet that is extended to users outside the company. It has also been described as a "state of mind" in which the Internet is perceived as a way to do business with other companies as well as to sell products to customers.

6 Private IP High-Level Architecture
Verizon Internet and Dial Network Access: Direct and Indirect Private IP Edge Router Private IP Core Customer Router Private IP MPLS Core DS3-OC192 Direct Private IP Connection: 56K, T1, T3, OC3 Indirect Frame UNI: NxDS0, T1, T3 Indirect ATM UNI: T1, OC3 Fault Management Service Level Agreement Provider Edge Router FR or ATM Private IP is a network capability that compliments and extends our customers’ networks. First, it readily integrates sites that use Frame Relay and ATM today. Secondly, the Private IP capability is being extended with solutions such as our network-based remote access that uses our Secure Interworking Gateway. Verizon Business provides the fault management and stringent, comprehensive end-to-end Service Level Agreements that our customers expect. Connectivity can be attained directly or indirectly. Direct access is when the customers router (referred to as the Customer Edge (CE) device) connects directly to on the of the Provider Edge (PE) router. This connectivity is typically via copper of fiber facilities but can also be via satellite services. Indirect access is where the CE router connects to a Frame Relay or ATM node. These nodes all interconnect with the Private IP network and the customers layer two data link connectivity simply passes through the Frame Relay or ATM switch and terminates into the PE device. Verizon's Private IP backbone topology has been engineered to maximize resiliency and minimize failover times. The P-core (Private IP Core) is a closed private MPLS backbone, i.e., there is no Internet connectivity, the network is dedicated solely to MPLS Label Switching and does not support any direct customer access connections. Using a dedicated P-core enhances network scalability by reducing OSPF adjacencies and providing OC48 trunking and high density aggregation of PE (Provider Edge) trunks. Every PE router is diversely trunked into two diverse P-core routers to insure a node will never be isolated. Dual Cisco GSR routers are deployed at each P-core site and diversely trunked using OC48 POS (Packet Over SONET) trunks. Every P-core router has at least two physically diverse SONET/SDH paths to other P-core sites to insure a node will never be isolated. It also shows the areas in which the SLAs cover. Note: unless a customer buys Managed Services with Private IP (Managed WAN) the SLA’s will cover metrics within the network, not out to the customer's CE or their router The Verizon Private IP network will automatically detect and dynamically reroute around transmission path failures.

Current Data 05 Access types are available Frame Relay at $380.00 Multilink Frame Relay at $ $20.00 Feature Additional Access types available Private line DS-1 access to PIP Ethernet Satellite DSL

9 Connectionless Environment Reduced Cost/Simplified Network Planning
Star Configuration Fully Meshed Configuration Private IP In typical Private Network solutions such as ATM and Frame Relay, Permanent Virtual Circuits (PVC’s) have to be established between all pairs of sites required to communicate. Each of these connections requires effort to manage and monitor and typically includes an additional cost component. With Private IP there are no layer 2 connections defined across the network, all sites have the ability to communicate with all other sites that are members of a common VPN. The customer can further define or limit the sites they would like to allow communications to occur between, but the typical design defaults to a full mesh which comes at no additional expense to the customer.

10 Private IP Routing Topologies
Multiple logical VPN topologies are available The most common and recommended topology for flexibility is the any-to-any VPN design Customer CPE can utilize Access Lists or Route Filters to control the routing topology learned by each location or can utilize VRF-Lite. Shared Intranet or Extranet Topology Support Frame Relay and ATM access to the Private IP service network not only extends the availability of the service to additional areas globally, but it also lends itself to a smooth migration for customers connected to these legacy networks looking to move to Private IP services Benefit: Provides an evolutionary service – anywhere the customer has existing Frame Relay or ATM connectivity, they can also use Verizon’s Private IP Service. Migrations from an existing Frame Relay or ATM network can be accomplished with minimal to no downtime since the access loops and entry ports can be reused to access the Private IP infrastructure. Scalability – access speeds from DS-0 through OC-3 and above are available and all speeds in between including Fractional DS-1, DS-1, NxDS-1, Fractional DS-3 and DS-3. These speeds are not limited to standard private line access, they can be realized thorough Ethernet, Satellite, DSL and other technologies as well. Benefit: Customers can expand their networks to higher speeds or to multiple locations in a fully meshed environment with minimal disruption. Sites can be designed independently based on local requirements, connectivity requirements at one location have no direct affect on connectivity at any other location. Security is inherent in Private IP and no encryption is required to guarantee that security. Benefit: Customers do not have to add a connection-oriented overlay to the Verizon’s Private IP Service network to encrypt tunnels, which would be required if the customer was using Internet Protocol Security (IPsec). The Verizon Private IP Service network is as secure as a layer 2 network. Any-to-any connectivity Benefit: Customers have the flexibility to choose either Frame Relay, ATM, Packet over SONET (POS), High Level Data Link Control (HDLC), Point to Point Protocol (PPP) or a combination of these access alternatives when building their networks. Regardless of the layer 2 access protocols chosen at each site, the Private IP network allows all of these sites to communicate without the need for formally defining PVC as in a later 2 switched environment. The benefits of this feature are most successfully realized in a fully-meshed network environment. Class of service (CoS) – Private IP offers industry leading 5 classes of service with 8 unique priority levels. This allows customers to prioritize applications to ensure mission critical traffic takes precedence over regular business traffic, and traffic with real time requirements such as voice is not adversely affected when it shares access and transport with other date applications. Benefit: The customer is able to leverage the benefits of classifying their data traffic by making the priority of the Type of Service (ToS) byte in the IP header which allows for them to indicate the performance levels required for any applications that share their infrastructure.

15 How Private IP Class of Service Is Applied
Private IP provides IP-based class of service: Complaint with IETF Diff-Serv RFCs Performs packet classification at customer ingress interfaces Customers gain access to these traffic priority classes based either on the Differentiated Services (DiffServ) Code Point (DSCP) settings or IP precedence settings applied to the Type of Service (ToS) byte in the IP header of their IP traffic. “Private IP provides IP-based class of service which is complaint with IETF Diff-Serv RFCs. Verizon Business has based the CoS scheme loosely upon the Diff-Serv model proposed by the IETF. The various traffic types may be marked for a particular CoS level by the CPE (at the customers premise). These code points (Differentiated Service Code Points) are not in the exact Diff-Serv code point form, but the Private IP network is designed to deliver the Per Hop Behaviour (PHB) envisioned for the Expedited Forwarding (EF) and Assured Forwarding (AF) PHBs of Diff-Serv. Private IP may be said to be ‘Diff-Serv-like’.” “The IP precedence bit can only be used with Standard or just Silver CAR service.” Private IP Provides IP based Class of Service Compliant with IETF Diff-Serv RFCs – The class of services offered do not include the entire spectrum defined by the IETF, but utilize a robust subset with simplicity and versatility in mind. Differentiated Services (DiffServ, or DS) is a protocol for specifying and controlling network traffic by class so that certain types of traffic get precedence - for example, voice traffic, which requires a relatively uninterrupted flow of data, might get precedence over other kinds of traffic. Differentiated Services is the most advanced method for managing traffic in terms of what is called Class of Service (CoS). Unlike the earlier mechanisms of 802.1p tagging and Type of Service (ToS), Differentiated Services avoids simple priority tagging and depends on more complex policy or rule statements to determine how to forward a given network packet. An analogy is made to travel services, in which a person can choose among different modes of travel - train, bus, airplane - degree of comfort, the number of stops on the route, standby status, the time of day or period of year for the trip, and so forth. For a given set of packet travel rules, a packet is given one of 64 possible forwarding behaviors - known as per hop behaviors (PHBs). Verizon Business has defined a service offering that utilized a subset of these available classes. A six-bit field, known as the Differentiated Services Code Point (DSCP), in the Internet Protocol (IP) header specifies the per hop behavior for a given flow of packets. Performs packet classification at customer ingress interfaces Customers gain access to these traffic priority classes based either on the Differentiated Services (DiffServ) Code Point (DSCP) settings or IP precedence settings applied to the Type of Service (ToS) byte in the IP header of their IP traffic. It is the customers responsibility to program their routers to identify specific applications and have their router identify the class of service required prior to forwarding it to the provider network. Examples of setting up a router to perform packet classification can be found in the “Private IP Solutions Design” class.
