Compared with traditional IP Internet, the carrier-class IP bearer network sees revolutionary changes which enable the IP network to become a manageable, maintainable, trustworthy secure network that offers the same QoS as the existing telecom network. The carrier-class IP network is able to support a new value chain system.

Driving Force of IP Bearer Network

Cost：Reduce cost

Single Multi-service IP bearer network instead of multiple separate network（PSTN/ATM/FR/DDN）

Flat IP network structure, reduce the network layer Provide same service cross different network Marketing：Improve the network competed ability

Different service provided by different port in same network instead of different network, improve response speed

Network components configured according requirement Providing multi-service improve the network values Services：Service binding improve the customer faithfulness

Redundancy and Backup

Principles

Basic principles

Backup cost _≤ loss caused by equipment failure

N+1 backup, through which the network operation will not be affected in case of any fault in key equipment, links, and modules 。

Backup of topology, equipment, and protocols

Access layer backup

Usually select the devices without redundancy function in key modules Usually not considering dual-host backup

Only provide the dual-uplink for backup if necessary

Convergence layer backup

Usually select devices with redundancy function in key modules 。

Usually considering dual-host backup, dual-uplink backup, and ring connection among convergence layer devices Core layer backup

Usually select devices with carrier-class reliability

Considering full mesh or partially mesh topology connection among core layer devices

(33)

Redundancy and Backup Principles

Symmetrical backup

Equal bandwidth on active and standby links; standby devices or links participating in operation

Asymmetrical backup

Less or equal bandwidth on standby links; standby devices or links participating in operation only in case of active link failure

Naming

Unique

The same IP address cannot be shared by two hosts in an IP network.

Continuous

Continuous addresses can facilitate path coverage, reduce the size of routing tables, and improve the efficiency of routing algorithms in the hierarchical network.

Expandable

Some address should be reserved during address assignment on each layer ensure the continuity of address coverage during network expansion.

Meaningful

Use the meaningful name

Designing Models for Addressing

Loopback address

Concept: logical interface, always UP Address planning

A 32-bit mask address is required.

Odd number of the last digit for routers, and even number for switches The nearer the devices is to the core, the smaller the loopback address becomes

Interconnection address

Concept: address for port connection of two network devices Address planning

A 30-bit mask address is required. Use smaller address for core devices Use continuous aggregatable address

Service address

Concept: gateway address and address for connecting Ethernet servers and hosts Address planning

(36)

Name the devices in the form of AA-B-YYYY-X to facilitate the management.

AA: device level and name, usually the name of the region

B: name of equipment supplier YYYY: equipment model

X: identity numbered by 1, 2... if the previous three items are the same

Examples:

Name of the first switch 3526E in Beihai: BH-H3-S3526E-1 Name of the router AR4640 at Chongkou: ChongKB-H3-AR4640

Designing Models for Naming

The description for each port in use should indicate and the peer connection and bandwidth. Naming format: name of peer device bandwidth

Example:

description to ZD-H3-NE16E-2 8MThis indicates the standby router NE16E with 8 Mbps bandwidth at the peer end.

(37)

Designing Models for Naming

Naming of logical interface

For MP, Ethernet sub-interface, and VLAN interface, assign meaningful numbers for their names.

For MP-group A/B/C, "A" indicates the slot number; "B" indicates card number, which is fixed; "C" is set to a digit that indicates the information of the peer device, for example, an identification digit of peer loopback interface address, or OSPF area number of peer device.

Strictly keep Ethernet sub-interface number consistent with the VLAN information.

Make a uniform plan for the use of numbers for global VLAN interfaces, for example, 100 and 200 for the VLAN of VPN, and 1000 for NM VLAN.

Comparison Among Routing Protocols

Selection of Distance Vector Protocol

and Link State Protocol

Distance vector protocol

Simple, flat network topology, no need of hierarchy design Simple hub-and-spoke topology

Network manager is unfamiliar with link state protocols and unable to shoot troubles in link state database

No need to consider convergence time in the worst case

Link state protocol

Hierarchical large network

Network administrator has rich knowledge about link state protocol Fast convergence is of much importance

(39)

Metric Method

Metric result affects scalability

Traditional distance vector protocol uses only hop counts

Routing protocol of new generation considers delay, bandwidth, and reliability

Hierarchical and Non-hierarchical

Routing Protocols

With non-hierarchical routing protocol, all routers must perform the same tasks

With hierarchical routing protocol, routers of different roles perform different tasks

(40)

Interior and Exterior Routing Protocols

Interior routing protocol runs within an enterprise network or autonomous system

Exterior routing protocol runs between autonomous systems

Classful and Classless Routing Protocols

Classful protocol

Discontinuous subnets invisible to each other Not support variable length subnet mask (VLSM) Classless protocol

Support discontinuous subnet and VLSM

(41)

Dynamic, Static, and Default Routing

Protocols

Static routing protocol

Manual configuration, suitable for stub network No protocol messages occupy bandwidth Easy fault removal

User has higher control over path selection Difficult to manage in large networks Routing details are not known

Default route

Simple; suitable for the network with only one ingress and egress link Routing details are not known

Routing Protocol Expandability

Whether there is any limit on metric Convergence speed upon network changes

Frequency and triggering method of route update and Link State Advertisement

Information transmission upon route update Bandwidth occupation by route update Advertisement range of route update CPU occupation by routing protocols Whether it supports default and static routes Whether it supports route aggregation

(42)

Selection of Routing Protocol in

Hierarchical Network

Selection of routing protocol for core layer

Support of redundancy links and load sharing Recommended: OSPF, IS-IS

Not recommended: RIP

Selection of routing protocol for convergence layer

Recommended: OSPF, IS-IS, RIPv2

Selection of routing protocol for access layer

Recommended: OSPF, RIPv2, static routing protocol IS-IS is not suitable for access layer

Redistribution Among Routing Protocols

A router runs more than one routing protocol Routing protocols need share routing information Determine boundary of routing areas

One-way distribution and two-way distribution

One-way distribution refers to distribution of routing information from one protocol to another protocol, and use of static or default route in the reverse direction.

Two-way distribution refers to distribution of routing information from one protocol to another protocol or vice versa.

Use route filter

Avoid re-advertisement of routes learnt from a protocol back to it Measures of different protocols are different.

IP Backhaul Network Planning and

Design Procedure

Network design and planning have different stage,

High level design (HLD): The HLD focuses on determining an

appropriate solution based on analysis of the existing networks and services. This phase is the network planning phase that comes out with the topology, services, protection, and QoS.

Low level design (LLD): Based on the outputs of the HLD, a

detailed network design is completed in the LLD phase, the

QoS Technologies for

IP Bearer Network

Foreword

IP bearer network bears multiple services such as voice, signaling, IPTV and Internet, it encapsulates these services in IP packet. In fact, the importance of these services is different. They should be forwarded differentially to ensure the quality of key service.

(65)

Objectives

Upon completion of this course, you will be able to: Know the QoS requirement of IP bearer network Master the principle of QoS

Know the QoS configuration process on VRP platform

Basic Concept of QoS

Qos (Quality of Service) means expected service quality of subscriber service in case of packet loss, delay, jitter and bandwidth while network communication.

Quality of Service (QoS) is used to measure the performance of service providers in meeting client’s requirements. Instead of giving accurate marks, QoS evaluation stresses on analyzing the service performance, which helps to guide service improvement.

IP QoS target:

Prevent and manage IP network congestion. Reduce the rate of IP message lose. Control IP network traffic.

Provide private bandwidth for specific subscribers or service. Support real-time service over IP network.

(69)

Three Models of IP QoS

Best-Effort model: Best-Effort model do not ensure the quality of service

IntServ model: The service sends a signaling to NM to request special QoS. The NM reserves the resource according to the traffic parameter to satisfy the request. DiffServ model: In case of network congestion, control the traffic and forward differently according to the different service level stipulated to solve the congestion.

Best-Effort Model

Best-Effort is a single service model

Using Best-Effort model can transfer any number of packets at any time without getting previous approval

There is no guarantee with respect to time delay and reliability

It is implemented by first in and first out (FIFO) queue technology

(70)

IntServ Model

Provide controllable end-to-end service.

Network units support QoS control mechanism.

The application applies to NM for specific QoS service. Signaling protocol deploys in network according to QoS request.

RSVP is the most frequently used.

QoS Requirement

QoS Requirements of Voice Traffic

Transfer delay < 100ms Jitter < 10ms

Independent physical or logical network, and able to prevent different illegal attacks
