What’s Carrier Ethernet ?

Quelle:

Scalability • Services and

Bandwidth • 100,000’s of EVC’s • From Mbps to

x10Gbps

Protection • 50ms Protection • End to End Path Protection • Aggregated Line & Node Protection

Hard QoS • Guaranteed end to end SLA • End to End CIR and EIR • Business, Mobile, Residential

TDM Support • Seamless integration of TDM • Circuit Emulation Services • Support existing voice applications

Service Management • Fast service creation • Carrier class OAM capabilities • Customer Network Management (CNM)

Policy-Based QoS Traffic Grouping Classification + QoS Profile => Policy • Classifications: L1-L4 information, WINS username (using EEM and DLCS), Observe and/or

overwrite 802.1p and IPDiffServ packet markings. • QoS Profile: Determines Bandwidth Management (e.g. Min. Bandwidth %; Max Bandwidth

%; priority). Option for Random Early Detection. • Layer Independent QoS: Use of Layer 3 & 4, IP DiffServ info without routing;

Scalable and Available Unix based Operating System

Modularity Availability and scale • Memory protection • Process Monitoring and Restart • Dynamic module loads (e.g. SSH2, SCP2)

Expensibility and open-ness New features faster

• POSIX APIs gives a great starting point for new code

• TCL and scriptable CLI enable easier management

• Configurable CLI • XML Internal configuration representation

Security • ClearFlow • Denial of Service Detection and Prevention • Hooks for Interactive Threat Containment

ExtremeWare XOS, Tested by Tolly Group

Key Findings of Tolly Group: Modularity has benefits: • Extensible OS • Higher network availability • Dynamically add functionality

Process recovery: • Higher network availability • No single process can take down the system

XOS ACL’s: • Wirespeed ACL forwarding • Dynamic ACL editing • Precise wirespeed “accounting” on matching ACL

Virtual Domains: • Ability to collapse multiple L3 switches on one device • Flexibility to support overlapping IP addresses

Pain Point: Ethernet Provisioning Complexity

SPs needs multi-vendor, multi-technology provisioning of:

E-Line services (Point to Point) Private line, and Virtual private line

E-LAN services (Multipt to Multipt) Private LAN, and Virtual private LAN

Advanced Traffic Management Engine

Bi-directional (ingress and egress) rate limiting • On egress, “phantom” scheduling is supported to distribute unused

bandwidth to other customers

3-tiered hierarchical rate limiting 1. Per application (up to 8 apps per customer) 2. Per customer (up to 4K per 10Gig link / 32K customer in total) 3. Per physical port (up to 160 = 2 * 80-port)

Packet Classification • Any data field can be used to classify the packet (in 4GNSS

programmable packet processor = Cartman)
