PTX Use Cases Chris Whyte We live in a connected world and the foundation for these connections is the network. Broadband Internet traffic is doubling each and every year (according to IDC) [or] Internet traffic worldwide will grow three-fold by the year 2017. (Internet Trends, Mary Meeker (KCPB) Today we have 2.5 billion Internet users in the world – roughly one-third of the Earth’s population. In the next decade, the number of Internet users will double to 5 billion (Mary Meeker, KPCB) That means that two-thirds of the world will be connected by 2023. When you add in the big trends of cloud, mobility, video and security, the combined rate of acceleration is placing unprecedented demands on the network. [Optional stats/factoids] 100 hours of video uploaded every single minute to YouTube (YouTube)   Mobile video traffic exceeded 50 percent for the first time in 2012. (Cisco VNI) Mobile network connection speeds more than doubled in 2012. (Cisco VNI) In 2012, a fourth-generation (4G) connection generated 19 times more traffic on average than a non-4G connection. Although 4G connections represent only 0.9 percent of mobile connections today, they already account for 14 percent of mobile data traffic. (Cisco VNI) [NOTE: Consider finding alternate source for above stats to avoid siting Cisco] As you just described (refer to pain points from previous slide), you are living in this world and feeling the pressure every day. Pradeep Sindhu founded Juniper 17 years ago on the belief that we should solve technology problems that matter most to our customers and that make a difference in the world. He recognized the importance of the network and the impact it would have on our world. Our mission is simple, but powerful; to connect everything and empower everyone. In today’s connected world, this mission is more relevant than ever. Here at Juniper we are focused on helping alleviate those pain points through our portfolio of high performance networking products. [T] And we do this by listening to our customers and helping them address their challenges and capitalize on their opportunities. PTX Use Cases Chris Whyte

Use Case Definitions MPLS LSR CORE Router responsible for MPLS label swap operations, a.k.a., label switching, in the (super)core backbone infrastructure. Requires small IP FIB and large LFIB. IP CORE Router responsible for IPv4/IPv6 routing in (super)core backbone. Typically requires full IP FIB. CONVERGED CORE (core/optical) Similar router to IP/LSR core but also performs packet optical integration. The convergence aspect is due to the integration of both L3 core routing/MPLS switching and transport functionality. Can require small or full IP FIB but large LFIB. METRO PACKET OPTICAL TRANSPORT Router responsible for providing packet optical transport (MPLS LSR) in metro core network. Typically requires medium to large LFIB. INTERNET PEERING Router responsible for connectivity to transit providers and peers to exchange of IPv4 and IPv6 reachability via eBGP in order to route internet traffic. Interconnects with IP/MPLS core. Typically requires full IP FIB and large LFIB. VPN Autonomous System Boundary Router (ASBR) Interprovider L3VPN Option A provides inter-AS VRF-to-VRF connectivity at the ASBRs. Interprovider L3VPN Option B provides inter-AS eBGP redistribution of labeled VPN-IPv4/v6 routes between neighboring ASs. Interprovider L3VPN Option C provides inter-AS multihop eBGP redistribution of labeled VPN-IPv4/v6 routes between source and destination ASs and with eBGP redistribution of labeled IPv4/v6 routes between neighboring ASs.

Use Case Definitions Seamless MPLS Border Node (BN) Border Node is LER (LSP ingress/egress) for intra-domain (LDP, RSVP-TE) and transit LSR for inter-domain LSP. Infrastructure Edge Transport IP and MPLS infrastructure related to the customers business. Used to Interconnect data center network/fabric/cloud over metro/WAN network. On the client side it is used for L3 aggregation and packet optical transport. DCI TRANSPORT Router responsible for interconnecting two or more datacenter (DC) sites using packet optical integration typically over dark fiber. Requires large LFIB. DCI Core Router responsible for interconnecting DC to IP/MPLS core backbone infrastructure. Requires small or full IP FIB but large LFIB.
