[. . . ] Alcatel-Lucent Service Router and Ethernet Service Switch M U LT I SERV I CE I N T EGR AT ED SERV I CE A DA P T ER | RELEASE 8 The Alcatel-Lucent Multiservice Integrated Service Adapter (MS-ISA) extends the level of intelligence of the industry-leading Alcatel-Lucent 7750 Service Router (SR) and 7450 Ethernet Service Switch (ESS) platforms by virtualizing advanced service capabilities into a unified service edge. The Alcatel-Lucent MS-ISA provides purpose-built, extended functionality and enables deeper levels of integrated service capabilities with higher scale than typically available from costly dedicated appliances. The Alcatel-Lucent MS-ISA provides a powerful platform for delivering advanced business and residential services on the 7750 SR and 7450 ESS without the need for costly external dedicated appliances. [. . . ] By integrating L2TP LNS on the 7750 SR, a single platform can support both PPP-based customers and provide an evolution towards IPoE (DHCP) while delivering a consistent user experience. One of the featured applications of L2TP LNS is the ability to introduce IPv6 services over existing BRAS, where IPv6 subscriber traffic is carried transparently in an L2TP tunnel and over IPv4 without any IPv6 support in the L2TP Access Concentrator (LAC). LNS services support the Alcatel-Lucent Service Router Operating System (SR OS) IPv4 and IPv6 ESM features, so IPv4, IPv6, and dual-stack IPv4 and IPv6 subscribers are concurrently supported. NAT services operate in two modes: Network Address and Port Translation (NAPT), with optimizations to provide scale and a subscriber-aware, Layer 2aware NAT. In NAPT mode, an operator can deploy centralized 7750 SR to provide IPv4 continuity with minimal changes to the access network and customer equipment. Layer 2-aware NAT enhances NAPT to create a virtual NAT table per subscriber, allowing customized NAT policies, integrated RADIUS accounting, and it uniquely permits all subscribers to share a common inside IP address to simplify IPv4 address assignment and administration. NAT services on the MS-ISA can also be used to extend IPv4 services and provide additional sources of revenue. NAT services allow for forwarding of traffic between VPN services with overlapping address spaces; for example, where a branch office VPN service needs to be merged into a larger corporate VPN service. NAT services can also be used to provide Internet access to an existing VPRN service. Benefits · Mitigates service provider IPv4 address exhaustion · Allows IPv4 services to continue and evolve during the migration to IPv6 services · Layer 2-aware NAT removes requirement for unique private IP addresses per subscriber · Allows for unique NAT subscriber policies that are consistent with other 7750 SR service access methods: PPP, PPPoE, L2TP LNS, and IPoE (DHCP) IPsec services IPsec services on the MS-ISA provide comprehensive, highly scalable, and network-integrated Layer 3 IPsec VPN connectivity as a Remote Access Concentrator (RAC) or for site-to-site or network-to-network encrypted IPsec security. Any physical interface can operate as an encrypted IPsec VPN port, enabling support for a diverse range of network traffic types, interfaces, and topologies. In addition, IPsec services can be combined with the 7750 SR comprehensive range of IP/MPLS service offerings. Feature highlights · Retains all ESM features for IPv4 and IPv6 · Supports up to 64, 000 L2TP sessions and 16, 000 L2TP tunnels per chassis · Concurrent support for NAT on the same MS-ISA Benefits · Features, management, and accounting for LNS subscribers are consistent with ESM services on existing IPoE (DHCP), PPP, and PPPoE subscriber access methods · Allows the introduction of IPv6 services over an IPv4 access network and LAC Feature highlights · NAT44 with high scale, high transaction rate, and N+1 MS-ISA redundancy · Two modes of operation: ¬ NAPT with traditional inside and outside addresses ¬ Layer 2-aware NAT where NAT is agnostic to subscriber (inside) IP addresses, allowing for overlap and reuse · Each host assigned port range blocks for greater scalability and reduced logging requirements · Per-subscriber port limits with application priority based on traffic forwarding class · Configurable high/low prioritization of applications traversing the NAT, based on traffic forwarding class · Concurrent support for L2TP Network Server on the same MS-ISA Feature highlights · High performance, hardware-based encryption and decryption and up to 16K concurrent IPsec tunnels per ISA · Tunnel-mode Encapsulating Security Payload (ESP) with authentication support · Bidirectional Forward Detection (BFD) within IPsec tunnels for fast tunnel failure detection NAT services NAT services on the Alcatel-Lucent MS-ISA add large-scale NAT capabilities to the Alcatel-Lucent 7750 SR, allowing service providers to conserve IPv4 addresses and maintain IPv4 Internet access while migrating to IPv6. NAT services on the MS-ISA were developed to satisfy service provider, large-scale NAT requirements, starting with the carrier-grade 7750 SR and MS-ISA platform and optimizing the software implementation to provide scale, transaction rates, and complete logging and accounting. Benefits · Integrated IPsec services allow combining of connectivity services, greater service scale and resiliency, and reduced network latency · Fully integrated with Alcatel-Lucent SR OS for unified service management, encryption and security, available to any Layer 3 service on any physical port Alcatel-Lucent Service Router and Ethernet Service Switch | Release 8 | Data Sheet 3 Video services The Alcatel-Lucent MS-ISA can be used to deliver superior Internet Protocol Television (IPTV) QoE by incorporating advanced video services into the network elements, offering high scalability and flexible deployment scenarios. Advanced video services enabled by the MS-ISA include: · Retransmission (RET) and Fast Channel Change (FCC) for IPTV running over RTP · Linear TV Ad Insertion (ADI) Benefits · Allows for a greater service footprint for IPTV services by ensuring quality video delivery where the last mile infrastructure would otherwise have unacceptable packet loss · Allows flexible, distributed, and hierarchical deployment options that optimize network resources, increase scale, and reduce CAPEX Linear TV Ad Insertion The Alcatel-Lucent MS-ISA Video Services support local/zoned Linear TV ADI into the multicast video stream, thereby opening up new sources of revenue by allowing IPTV service providers to participate in the advertising value chain. The Alcatel-Lucent MS-ISA supports up to 16 unique advertisement zones per main multicast channel stream.
