Carrier Ethernet Technology : Multicast and QoS

  1. 1. Netmanias Technical Document: Carrier Ethernet Technology – Multicast and QoS www.nmcgroups.com About NMC Consulting Group NMC Consulting Group is an advanced and professional network consulting company, specializing in IP network areas (e.g., FTTH, Metro Ethernet and IP/MPLS), service areas (e.g., IPTV, IMS and CDN), and wireless network areas (e.g., Mobile WiMAX, LTE and Wi-Fi) since 2002.

In existing traditional TPS networks, IPTV broadcast is delivered using IGMP and PIM protocols. 2. In MPLS networks, it can be delivered using P2MP LSP and RSVP-TE extension for P2MP allowing fast convergence which is a key advantage of MPLS. 3. Carrier Ethernet technology should provide effective multicast replication and fast convergence functions. IGMP PIM Ethernet Multicast IP Multicast RSVP-TE for P2MP MPLS P2MP LSP Ethernet IP MPLS

PBB (+ STP) Market Requirement • Multicast should be supported and fast recovery from link or node failure should be ensured System Requirement see an example in the following page

In MEF, (1) UNI port-based bandwidth control, (2) EVC-based bandwidth control and (3) COS-based bandwidth control within EVC are defined for enterprise services. 2. Some operators provide both COS-based bandwidth control and EVC-based bandwidth control (will be introduced later) 3. Therefore, PBT equipments should provide H-QoS function listed in step 2 as well as basic functions defined by MEF.

Per EVC Bandwidth Control 3. Per COS Bandwidth Control 4. H-QOS: Per COS + Per EVC Bandwidth Control Market Requirement • Followings should be supported for enterprise services defined by MEF: (1) UNI port-based bandwidth control, (2) EVC-based bandwidth control and (3) COS-based bandwidth control within EVC (Support of the combinations of 1, 2 and 3).
