Ethernet VPN Prduct Definitin A Virtual Private Netwrk (VPN) service is a private netwrk that shares a cmmn platfrm with ther users, this service that has been ppular ver the past few years. In parallel, there has been an increasing interest in scalable, end-t-end Ethernet services. Several develpments in the area f VPNs have helped t enable Ethernet-based VPNs. Chief amng these are tw MPLS technlgies; Virtual Leased Line (VLL) and Virtual Private LAN Service (VPLS) Virtual Leased Line (VLL), als knwn as Ethernet Pint-t-pint VPN service, emulates the behavir f a leased line between tw pints. In the industry, this technlgy is als referred t as Virtual Private Wire Service (VPWS) r Ethernet ver MPLS (EMPLS). VLLs use the pseud-wire encapsulatin fr transprting Ethernet traffic ver an MPLS tunnel acrss an IP/MPLS netwrk. Virtual Private LAN Service (VPLS), als knwn as Ethernet Multipint-t-multipint VPN service, emulates the behavir f a traditinal bridge between multiple pints. Ethernet Pint-t-multipint VPN service can be cnsidered a special cases f Ethernet Multipint-t-multipint VPN service. Service prviders can use these technlgies t ffer advanced services t their custmers such as managed VPN services. Similarly, large enterprises can use these technlgies t virtually segment their netwrks based n business needs, and acrss gegraphical bundaries.

IP VPN Prduct Definitin An IP VPN (Virtual Private Netwrk) service is a private netwrk (cannt be seen by users utside the VPN service) that shares a cmmn netwrk with ther users fr IP traffic nly. Anther name fr an IP VPN is a Virtual Private Ruted Netwrk (VPRN). IP VPN emulates the behavir f a ruter between multiple pints. Several elements cmbine fr an IP VPN service: 1. Any number f legs can attach t the IP VPN service at any MPLS service ruter. 2. This service functins like ne large virtual ruter. 3. IP VPN services are terminated int PE (Prvider Edge) ruters. 4. Extending the IP VPN interface t the custmer allws IP VPN services t be extended frm the PE ruters. This service is much mre cmplex than Ethernet VPNs and requires mre interactin between custmer and service prvider fr IP addressing and ruting prtcls.

Dedicated Internet Access Prduct Definitin Dedicated Internet Access prvides ruted Internet bandwidth ver the FPL FiberNet netwrk t multiple, gegraphically diverse, peering lcatins within Flrida. Based n the Alcatel-Lucent Service Ruting platfrm, the FPL FiberNet netwrk ensures these cnnectins are fully resilient and highly reliable. FPL FiberNet has established intercnnectin arrangements in Miami (NAP) and diverse lcatins in Flrida, allwing us t survive disaster scenaris affecting any particular facility. Additinally, ur Dedicated Internet Access service includes dynamic selectin f ptimal rutes amng these hub sites. This allws FPL FiberNet t ffer a higher level f perfrmance and reliability when cmpared t any single lcatin service prvider.

Prtectin ver the lcal fiber infrastructure is prvided by LAG links ver a Switch Ethernet Netwrk. The benefit prvided by this feature is that in the event f a fiber cut in the lcal fiber infrastructure r a prt failure at either PE (blue) r CE (teal), 100% f CIR bandwidth (PIR bandwidth is nt prtected) wuld still be available at custmer premise.

Fr custmers that require a larger MTU, we ffer supprt fr Jumb frames that increases MTU t 9000 bytes, available nly with 1000Mbps prts. Prt Upgrade The standard Ethernet VPN r IP VPN slutin cmes with a 100Mbps prt fr CIR < 100 Mbps. Fr custmers that require a 1000Mbps prt but d nt wish t cmmit t at least 100Mbps CIR, we ffer a value added feature t upgrade standard 100Mbps prt t a 1000Mbps prt. 11

VLAN Service The standard Ethernet VPN prvides service t a custmer thrugh a physical prt per lcatin. As a value added feature, multiple services can be delivered t a custmer at a single lcatin thrugh the same physical prt. This feature, in accrdance with IEEE 802.1q, requires that services be tagged at the lcatin with different VLAN tags s that traffic can be separated by the custmer and FPL FiberNet. VLAN 200 = Dedicated Internet Access Bth services prvided ver same physical prt Custmer Equipment NID PE PE Lcal netwrk prviding Access frm FN t Custmer NID Custmer Equipment VLAN 100 = Ethernet Pint-t-pint VPN Additinal Prt The standard Ethernet VPN and IP VPN prvides service t a custmer thrugh ne physical prt per lcatin. As a value added feature, ne additinal 100Mbps r 1000Mbps LAG prt can be added as a shadw prt. In rder t implement LAG prts, the prts need t be the same type and, usually, terminate at the same custmer equipment. PE Lcal netwrk prviding Access frm FN t Custmer NID CE : NID Custmer Equipment Nte: Available nly with prtectin feature r if cmmn equipment is present Bursting The standard Ethernet VPN and IP VPN slutins prvide the highest quality f service up t the Cmmitted Infrmatin Rate (CIR), with the Peak Infrmatin Rate (PIR) set equal t CIR (i.e. CIR = PIR). As a value added feature, PIR can be set at maximum prt speed (100 r 1000Mbps) r fr multiple LAG prt grups, at the maximum LAG grup speed. Fr DIA, in additin t the abve, PIR can be set frm 200-1000Mbps in increments f 100Mbps r bursting can be charged per usage.(available Q3 2008) Bursting bandwidth is available at best-effrt quality. Since bursting is best-effrt, verall service quality may degrade during perids f bursting if critical packets are nt able t meet required SLAs (i.e. delay, jitter, lss packets, etc.). T mitigate this effect, custmers can priritize their traffic using Quality f Service feature described n next page. 12

Multicasting The standard Ethernet VPN and IP VPN services have limited (1 Mbps) multicasting bandwidth. As a value added feature, multicasting can be supprted. This feature will enable custmers t multicast withut limitatins (up t 2 Gbps). Nte: This feature is nly applicable t Pint-t-Multipint and Multipint-t-multipint VPNs Inter-Metr The standard Ethernet VPN and IP VPN services are designed fr traffic within any FPL FiberNet Metr. As a value added feature, we can expand these services acrss any FPL FiberNet Metr. FPL FiberNet MPLS Metrs: 1. Miami / Frt Lauderdale / Palm Beach 2. Tampa / St. Petersburg 3. Orland E/W 4. Jacksnville / Daytna 5. Sarasta / Frt Myers Quality f Service The standard Ethernet VPN and IP VPN services prvide fr the highest quality f service fr the Cmmitted Infrmatin Rate (CIR).
