EPG on Juniper

           Based on the Juniper M320 or M120 router, the EPG supports Physical Interface Cards (PICs) of the following types: ·          EPG services PIC : All EPG application software entities run on the EPG services PIC. These entities consist of Globe Session Controller (GSC), SGW Session Controller (SSC) and PGW Session Controller (PSC) for Control Plane, and Packet Processor (PP) and L2TP Packet Processor (TPP) for User Plane. The EPG services PIC is PB-GGSN3 Services PIC. ·          Network interface PIC: The network interface PIC provides 1GE or 10GE Ethernet connectivity for the EPG. ·          Standard services PIC : the standard services PIC runs platform-generic services, such as encapsulation and decapsulation of user payload into Generic Routing Encapsulation (GRE) or IPsec tunnels. For EPG on Juniper, the following Network Interface PICs are supported: ·          2-Port Gigabit Ethernet  PIC ·          4-Port Gigabit Ethernet PIC ·          8-Port Gigabi

EPG- Evolved Packet Gateway

The EPG combines the GGSN, SGW and PGW functions in one physical node. In addition, the evolved platform adaptation layer supports the EPG application running on both operating systems: Junos OS (the OS of Juniper M series routers) and IPOS (the OS of Smart Services Router),  The EPG is available on different hardware platforms: ·          Juniper (M320, M120) ·          Smart Services Router (SSR 8020) The EPG based on Juniper hardware is simply called EPG on Juniper and the EPG based on SSR hardware is respectively called EPG on SSR. In the EIN documents, these terms are used to distinguish between these hardware platforms. If the hardware platform does not matter, the EPG term covers all possible EPG configurations. The EPG on SSR has an increased capacity, up to 10 times greater than the EPG on Juniper. Therefore, the EPG on SSR has a big impact on the PS core network, and this needs to be sustained in terms of capacity from the other PS network elements and

What is 5G ?

It is a mobile broadband system that will provide higher performance than is available today’s most advanced 4G networks.  These performance improvements will be measurable in terms of speed, latency, reliability, scale and openness.  The 5G system will achieve this higher performance by integrating many new devices over multiple wireless technologies with new management and orchestration systems.  A 5G system will include existing and new technologies such as: LTE, new radio technology, highly variable end devices especially for M2M, virtualized software and management and orchestration systems.  There will be a single global 5G standard to ensure global coverage.  It will be deployed in commercial service by 2020, but components may be ready earlier.  The main focus is now on research where evolution of existing technologies is on-going in parallel with innovation of new technologies. A lot of research is done in cooperation with universities and partners. By join forces, we ca

SIGNAL ENCODING

We can represent bits as digital electrical signals in many ways. Data bits can be coded into following two types of codes : (a)                  Non Return to Zero (NRZ Codes). (b)                  Return to Zero (RZ Codes) NRZ Codes In this type of codes, the signal level remains constant during a bit duration. There are 3 types of NRZ codes. NRZ-L Coding Bit is represented as a voltage level which remains constant during the bit duration. NRZ-M Coding A transition in the beginning of a bit interval whenever there is a 'Mark. NRZ-S Coding A transition in the beginning of a bit interval whenever there is a 'Space'. Let us see the following bit stream 10100110 into three different types of NRZ codes  RZ Codes: Following are the RZ Codes (a)         Manchester Coding (b)         Biphase-M Coding (c)          Biphase-S Coding (d)         Differential Manchester Coding.
