Re: gre gtp tunnel
The GRE and GTP inclusion arrangement empowers the Cisco SCE to screen and control the GRE and GTP. This area incorporates: •GRE Feature Overview •GTP Feature Overview GRE Feature Overview Burrowing conventions are utilized as a part of many systems for different purposes, including VPNs, movement building (TE), security, et cetera. A few epitomes are IP based, for example, GRE, and some are set in lower levels, for instance in Layer 2.5. Cisco SCE locally breaks down IP-based activity. IP locations are the reason for stream order (the 5-tuple contains IP locations) and supporter recognizable proof (most usually utilized endorser ID is the endorser IP address). In burrowed systems, the IP parcel is additionally typified by some embodiment convention. To investigate the IP parcel, Cisco SCE necessities to perform particular parsing of the embodying convention. Besides, in a few systems, the IP addresses utilized inside the burrowed activity are private IP addresses. For instance, addresses that are not remarkable among the streams seen on a solitary SCE. In these cases, the recognizable proof of the source and goal of the bundle must be founded on both the IP address and the passage data found in the parcel. In systems with private IP addresses, or without them, it is attractive to treat an entire fragment of the system as a solitary supporter. Such a section might be an entire VPN, a particular VLAN, a particular passage, et cetera. In these cases, SCE characterizes the endorser by a general identifier that applies to all the IP addresses creating activity over that system section. This strategy permits the SCE to neglect the particular customer, and allude just to the gathering it is related with, when characterizing the endorsers. GTP Feature Overview In a General Packet Radio Service (GPRS) spine organize, GTP is an abnormal state burrowing convention used to convey flagging and information. A GPRS spine system (or center system) contains a few hubs of GPRS Support Node (GSN), which speak with each other utilizing IP as appeared in Figure 1. GSNs are either Serving GPRS Support Nodes (SGSNs) or Gateway GPRS Support Nodes (GGSNs). The SGSN is utilized to speak with Mobile Terminal (MT) gear or transfer information inside the spine system to outside associations and the GGSNs thusly controls these SGSNs. This handing-off is executed in the spine organize by utilizing GTP on top of UDP/IP (GTPv1). A GTP passage is a virtual association between two GSNs (for the most part between SGSN/RNC and GGSN). One GTP Tunnel can contain a few multiplexed client information associations (a few MTs can share same GTP burrow with no learning of each other). The GTP burrow utilizes a bundle information way in the GPRS spine arrange, which is the UDP/IP way. The evolvement of the remote innovation makes the remote fragment more like the wire line showcase and subsequently the interest for profound parcel investigation (DPI) applications in this portion is expanded. The GTP bolster enables SCE to screen neighborhood and wandering activity in the Gn/Gp channels. Separated Services Code Point (DCSP) stamping of dynamic application can be actualized in the GTP condition also.
