Netmanias Blog 9일, 10일자에서 LTE QoS에 대해서 소개드린 적이 있습니다. 오늘은 LTE QoS 실전 편으로 LTE망에서 LTE QoS를 이용하여 P2P 트래픽을 제어하는 예를 보여 드리도록 하겟습니다. 가상의 통신사업자 "NMC Telecom"이 있다 하구요, 이 통신사업자는 LTE 가입자에게 다음과 같은 상품(Service Plan)을 제공하고 있습니다. 인터넷 사용에 대해서는 대역폭 제어를 하지 않습니다. 다만 BitTorrent와 같은 P2P 트래픽에 대해서는 하향(Download) 512Kbps, 상향(Upload) 128Kbps로 속도 제어를 합니다. 이를 위한 LTE QoS 구조가 아래와 같습니다.

Let's say there is a network operator named "NMC Telecom", and it offers a service plan with the following features: No bandwidth limitation for Internet usage Data rate limitation (512 Kbps for download, and 128 Kbps fo...

We will talk about LTE QoS this time. QoS functions provided by any network, whether wired or wireless, are all based on standards (IETF RFC, IEEE 802, 3GPP TS, etc.). They may work differently using different standards depending on whether the network is wired (Ethernet/IP/MPLS) or wireless (LTE/WiBro/Wi-Fi). But, basically what the QoS is about is that traffic quality is guaranteed (i) if...
