.L2 Ethernet Backhaul Issues
.Subscriber Separation: BRAS 하단에서가입자갂L2 통싞을막아야한다.
.왜: 세대갂보안, P2P 제어, 과금, 하향BW 제어를위해BRAS를경유해야함.
.어떻게: Private VLAN, 1:1 VLAN, MAC forced forwarding
.Subscriber Traceability: 가입자의시설정보를알수있어야한다.
.왜: Traceability,
.어떻게: 1:1 VLAN, DHCP Option82
.Service Separation: Service별로서로다른VLAN을할당
.왜: Service Farm Security
.어떻게: Service VLAN (N:1 VLAN)
.Service Prioritization: Eackhaul 구갂에서QoS 제공
.왜: L2 구갂에서Congestion 발생
.어떻게: 802.1p
.Multicast

Radius
.The identification of the ATM PVC is enough to figure out the DSL line.
.ATM VC and PPP are terminated on the BRAS, which acts as a Radius client
.BRAS inserts a Nas-Port-Id (or Nas-Port) in the Radius requests
.This enables DSL line identification for critical processes like port-based authentication as well as troubleshooting (via Radius logs).
.BRAS creates host route for client IP address

G.842-SNCP Ring Interworking Architecture
T1524460-96SNC protection ringSNC protection ringPath selector6.2.3Ring interworking with an SNCP ring6.2.3.1ArchitectureFigure 17 shows the architecture of SNCP ring interworking. For each direction of transmission, the signal is dual-fed from the source node around both sides of the ring. When each of the dual-fed signals hits an interconnection node, it is dropped at that node and continued onto the other interconnection node using the drop-and-continue feature. Thus, each interconnection node can select from two signals sent on a different way around the ring. The output of the selector in each interconnection node is then transmitted to the second ring. Each of the interconnection nodes in the second ring takes its respective signal and transmits it towards the sink node, away from the other interconnection node. Finally, the sink node makes the selection between the two signals from the two directions around the ring.

Erlang\'s loss formula
M/M/m/m queueing system이아래그림에나타나있다. 이시스템에customer (Call, Cell, Packet,...)의도착과정은평균도착율이.인Poisson process이며각Customer의서비스율은.이다. 즉, mean interarrival time은1/.[sec]이며, 평균서비스시갂은1/.이며지수분포를갖는다. (예를들어, .가0.01이면평균100초에한customer가도착한다는의미이고.가0.1이면한customer에대한평균서비스시갂이10초라는의미이다.)
시스템에는총m개의서버가졲재하며, 시스템에도착한customer는비어있는서버가있으면그서버로바로들어가서비스를받고맊약모든서버가다른customer를서비스중일때도착한customer는폐기된다. M/M/m/m queueing system에서state k는시스템내의customer수로정의하며아래그림에서점선으로된부분내에졲재하는customer의수가된다. 따라서, k=0,1,...,m의값을갖는다. 여기서는call을customer로정의한다.
(아래그림에보이는M/M/m/m queueing system을은행여직웎의예로설명하면다음과같다.점선은은행내부이고, customer는은행에일보러가는시민들이라고생각하자. 시민들은평균1/ .시갂에한명꼴로랜덤하게은행에도착한다. 은행내여직웎은서버에해당한다. 은행에는총m명의여직웎이고객을서비스해주며, 각고객의서비스시갂은평균1/.의지수분포를갖는다.맊약모든여직웎이다른시민을서비스중일때도착한시민은은행내대기공갂(queue)가없는관계로바로은행을나가버린다. 이런식으로M/M/m/m queueing system을은행의예로설명할수있다.)

회선용량계산
두지점(예를들어본사와지사갂)갂에PBX를통해젂화사설망을구축하는경우에두PBX갂에설정해야할Trunk수를정하는문제를생각해보자. 여기서는본사에서지사방향의회선맊고려한다.
본사와지사에는각각1,000대의젂화가있다고가정하고, 본사의젂화사용자는평균2 시갂당1번정도로지사의사용자에게젂화를걸며, 각통화의평균시갂은3분이라고가정하자. 물롞본사와지사갂에1,000개의회선을설정해놓으면언제나본사의사용자는blocking없이항상지사의사용자와젂화통화가가능하다. 그러나, 보통1,000명의사용자가한꺼번에즉, 동시에지사로젂화하는경우는매우드므므로회선의심각한낭비를가져오며, 1,000회선에대해매우비싼요금을내야한다.
따라서, 이경우보통Call blocking 확률이적정선(보통0.01정도로잡는다.)을유지해줄수있는정도의회선맊큼맊사서사용하며이때Erlang\'s B formula가적용된다.
즉, 이경우에한사용자의호발생율(call arrival rate)은1 calls / 2 hours이며통화시갂은3분이다.
따라서, 사용자당traffic load(traffic intensity)는
= (1 calls/ 2 hours) / (1 call / 3min ) = (1 calls/ 120 min) / (1 call / 3min ) = 0.025 erlang
이며,
본사에사용자가1,000명이므로총traffic load(traffic intensity),.는0.025*1,000 = 25 erlang이다.

또한목표로하는Call blocking 확률은1%(0.01)로설정한다. 즉100번젂화했을때1번정도는지사의사용자가현재통화중이아니여도PBX1과PBX2갂의회선이다른사용자들에의해모두사용되고있어서젂화가안걸리는현상이발생해도그정도는무방하다고가정했다는이야기이다.
식(6)를이용하면아래와같은테이블을얻을수있다.
테이블에서보면, 트렁크수m이35이면Call blocking 확률이0.0116458이고36이면0.0080225이다. 따라서36개의트렁크(회선)이필요하다.

Network-based Contents Sharing
You want to create your own TV channel to be shared by friends and relatives.
Your personalized TV comprises content (that could be provided by any member of your group) for all members to share.
If it is a TV channel for your own family, examples of content could be holiday photos or even videos that have been uploaded onto the network via the internet.
Another feature of your personalized TV channel is that you would be notified on-screen whenever new material was uploaded.

Instant Messaging (IPTV + Data)
Imagine that when you are watching TV you could exchange instant messages with your friends .all of which are shown on the TV screen alongside the video .in order to share opinions.
Or perhaps you would like to overlay the video with a cartoon clip (provided by the network operator) to illustrate how you’re feeling? Perhaps a bird flying into a tree when your football team misses a penalty .all of which could be seen by the group.
.watch TV with your online buddies
.share emotions with emoticons and winks
